See deflatePending(), + which can be used if desired to determine whether or not there is more ouput + in that case. + + Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to + decide how much data to accumulate before producing output, in order to + maximize compression. + + If the parameter flush is set to Z_SYNC_FLUSH, all pending output is + flushed to the output buffer and the output is aligned on a byte boundary, so + that the decompressor can get all input data available so far. (In + particular avail_in is zero after the call if enough output space has been + provided before the call.) Flushing may degrade compression for some + compression algorithms and so it should be used only when necessary. This + completes the current deflate block and follows it with an empty stored block + that is three bits plus filler bits to the next byte, followed by four bytes + (00 00 ff ff). + + If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the + output buffer, but the output is not aligned to a byte boundary. All of the + input data so far will be available to the decompressor, as for Z_SYNC_FLUSH. + This completes the current deflate block and follows it with an empty fixed + codes block that is 10 bits long. This assures that enough bytes are output + in order for the decompressor to finish the block before the empty fixed + codes block. + + If flush is set to Z_BLOCK, a deflate block is completed and emitted, as + for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to + seven bits of the current block are held to be written as the next byte after + the next deflate block is completed. In this case, the decompressor may not + be provided enough bits at this point in order to complete decompression of + the data provided so far to the compressor. It may need to wait for the next + block to be emitted. This is for advanced applications that need to control + the emission of deflate blocks. + + If flush is set to Z_FULL_FLUSH, all output is flushed as with + Z_SYNC_FLUSH, and the compression state is reset so that decompression can + restart from this point if previous compressed data has been damaged or if + random access is desired. Using Z_FULL_FLUSH too often can seriously degrade + compression. + + If deflate returns with avail_out == 0, this function must be called again + with the same value of the flush parameter and more output space (updated + avail_out), until the flush is complete (deflate returns with non-zero + avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that + avail_out is greater than six to avoid repeated flush markers due to + avail_out == 0 on return. + + If the parameter flush is set to Z_FINISH, pending input is processed, + pending output is flushed and deflate returns with Z_STREAM_END if there was + enough output space. If deflate returns with Z_OK or Z_BUF_ERROR, this + function must be called again with Z_FINISH and more output space (updated + avail_out) but no more input data, until it returns with Z_STREAM_END or an + error. After deflate has returned Z_STREAM_END, the only possible operations + on the stream are deflateReset or deflateEnd. + + Z_FINISH can be used in the first deflate call after deflateInit if all the + compression is to be done in a single step.

This allows the caller to determine the length of the + deflate block header for later use in random access within a deflate block. + 256 is added to the value of strm->data_type when inflate() returns + immediately after reaching the end of the deflate block header. + + inflate() should normally be called until it returns Z_STREAM_END or an + error. However if all decompression is to be performed in a single step (a + single call of inflate), the parameter flush should be set to Z_FINISH. In + this case all pending input is processed and all pending output is flushed; + avail_out must be large enough to hold all of the uncompressed data for the + operation to complete. (The size of the uncompressed data may have been + saved by the compressor for this purpose.) The use of Z_FINISH is not + required to perform an inflation in one step. However it may be used to + inform inflate that a faster approach can be used for the single inflate() + call. Z_FINISH also informs inflate to not maintain a sliding window if the + stream completes, which reduces inflate's memory footprint. If the stream + does not complete, either because not all of the stream is provided or not + enough output space is provided, then a sliding window will be allocated and + inflate() can be called again to continue the operation as if Z_NO_FLUSH had + been used. + + In this implementation, inflate() always flushes as much output as + possible to the output buffer, and always uses the faster approach on the + first call. So the effects of the flush parameter in this implementation are + on the return value of inflate() as noted below, when inflate() returns early + when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of + memory for a sliding window when Z_FINISH is used. + + If a preset dictionary is needed after this call (see inflateSetDictionary + below), inflate sets strm->adler to the Adler-32 checksum of the dictionary + chosen by the compressor and returns Z_NEED_DICT; otherwise it sets + strm->adler to the Adler-32 checksum of all output produced so far (that is, + total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described + below. At the end of the stream, inflate() checks that its computed Adler-32 + checksum is equal to that saved by the compressor and returns Z_STREAM_END + only if the checksum is correct. + + inflate() can decompress and check either zlib-wrapped or gzip-wrapped + deflate data. The header type is detected automatically, if requested when + initializing with inflateInit2(). Any information contained in the gzip + header is not retained unless inflateGetHeader() is used. When processing + gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output + produced so far. The CRC-32 is checked against the gzip trailer, as is the + uncompressed length, modulo 2^32. + + inflate() returns Z_OK if some progress has been made (more input processed + or more output produced), Z_STREAM_END if the end of the compressed data has + been reached and all uncompressed output has been produced, Z_NEED_DICT if a + preset dictionary is needed at this point, Z_DATA_ERROR if the input data was + corrupted (input stream not conforming to the zlib format or incorrect check + value, in which case strm->msg points to a string with a more specific + error), Z_STREAM_ERROR if the stream structure was inconsistent (for example + next_in or next_out was Z_NULL, or the state was inadvertently written over + by the application), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR + if no progress was possible or if there was not enough room in the output + buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and + inflate() can be called again with more input and more output space to + continue decompressing.

Some information +can also be found in the JPEG FAQ (Frequently Asked Questions) article. See +ARCHIVE LOCATIONS below to find out where to obtain the FAQ article. + +If you want to understand how the JPEG code works, we suggest reading one or +more of the REFERENCES, then looking at the documentation files (in roughly +the order listed) before diving into the code. + + +OVERVIEW +======== + +This package contains C software to implement JPEG image encoding, decoding, +and transcoding. JPEG (pronounced "jay-peg") is a standardized compression +method for full-color and grayscale images. + +This software implements JPEG baseline, extended-sequential, and progressive +compression processes. Provision is made for supporting all variants of these +processes, although some uncommon parameter settings aren't implemented yet. +We have made no provision for supporting the hierarchical or lossless +processes defined in the standard. + +We provide a set of library routines for reading and writing JPEG image files, +plus two sample applications "cjpeg" and "djpeg", which use the library to +perform conversion between JPEG and some other popular image file formats. +The library is intended to be reused in other applications. + +In order to support file conversion and viewing software, we have included +considerable functionality beyond the bare JPEG coding/decoding capability; +for example, the color quantization modules are not strictly part of JPEG +decoding, but they are essential for output to colormapped file formats or +colormapped displays. These extra functions can be compiled out of the +library if not required for a particular application. + +We have also included "jpegtran", a utility for lossless transcoding between +different JPEG processes, and "rdjpgcom" and "wrjpgcom", two simple +applications for inserting and extracting textual comments in JFIF files. + +The emphasis in designing this software has been on achieving portability and +flexibility, while also making it fast enough to be useful. In particular, +the software is not intended to be read as a tutorial on JPEG. (See the +REFERENCES section for introductory material.) Rather, it is intended to +be reliable, portable, industrial-strength code. We do not claim to have +achieved that goal in every aspect of the software, but we strive for it. + +We welcome the use of this software as a component of commercial products. +No royalty is required, but we do ask for an acknowledgement in product +documentation, as described under LEGAL ISSUES. + + +LEGAL ISSUES +============ + +In plain English: + +1.

Another support script, install-sh, is copyright by X Consortium +but is also freely distributable. + +The IJG distribution formerly included code to read and write GIF files. +To avoid entanglement with the Unisys LZW patent (now expired), GIF reading +support has been removed altogether, and the GIF writer has been simplified +to produce "uncompressed GIFs". This technique does not use the LZW +algorithm; the resulting GIF files are larger than usual, but are readable +by all standard GIF decoders. + + +REFERENCES +========== + +We recommend reading one or more of these references before trying to +understand the innards of the JPEG software. + +The best short technical introduction to the JPEG compression algorithm is + Wallace, Gregory K. "The JPEG Still Picture Compression Standard", + Communications of the ACM, April 1991 (vol. 34 no. 4), pp. 30-44. +(Adjacent articles in that issue discuss MPEG motion picture compression, +applications of JPEG, and related topics.) If you don't have the CACM issue +handy, a PDF file containing a revised version of Wallace's article is +available at http://www.ijg.org/files/Wallace.JPEG.pdf. The file (actually +a preprint for an article that appeared in IEEE Trans. Consumer Electronics) +omits the sample images that appeared in CACM, but it includes corrections +and some added material. Note: the Wallace article is copyright ACM and IEEE, +and it may not be used for commercial purposes. + +A somewhat less technical, more leisurely introduction to JPEG can be found in +"The Data Compression Book" by Mark Nelson and Jean-loup Gailly, published by +M&T Books (New York), 2nd ed. 1996, ISBN 1-55851-434-1. This book provides +good explanations and example C code for a multitude of compression methods +including JPEG. It is an excellent source if you are comfortable reading C +code but don't know much about data compression in general. The book's JPEG +sample code is far from industrial-strength, but when you are ready to look +at a full implementation, you've got one here... + +The best currently available description of JPEG is the textbook "JPEG Still +Image Data Compression Standard" by William B. Pennebaker and Joan L. +Mitchell, published by Van Nostrand Reinhold, 1993, ISBN 0-442-01272-1. +Price US$59.95, 638 pp. The book includes the complete text of the ISO JPEG +standards (DIS 10918-1 and draft DIS 10918-2). +Although this is by far the most detailed and comprehensive exposition of +JPEG publicly available, we point out that it is still missing an explanation +of the most essential properties and algorithms of the underlying DCT +technology. +If you think that you know about DCT-based JPEG after reading this book, +then you are in delusion. The real fundamentals and corresponding potential +of DCT-based JPEG are not publicly known so far, and that is the reason for +all the mistaken developments taking place in the image coding domain. + +The original JPEG standard is divided into two parts, Part 1 being the actual +specification, while Part 2 covers compliance testing methods. Part 1 is +titled "Digital Compression and Coding of Continuous-tone Still Images, +Part 1: Requirements and guidelines" and has document numbers ISO/IEC IS +10918-1, ITU-T T.81. Part 2 is titled "Digital Compression and Coding of +Continuous-tone Still Images, Part 2: Compliance testing" and has document +numbers ISO/IEC IS 10918-2, ITU-T T.83. +IJG JPEG 8 introduced an implementation of the JPEG SmartScale extension +which is specified in two documents: A contributed document at ITU and ISO +with title "ITU-T JPEG-Plus Proposal for Extending ITU-T T.81 for Advanced +Image Coding", April 2006, Geneva, Switzerland. The latest version of this +document is Revision 3. And a contributed document ISO/IEC JTC1/SC29/WG1 N +5799 with title "Evolution of JPEG", June/July 2011, Berlin, Germany. +IJG JPEG 9 introduces a reversible color transform for improved lossless +compression which is described in a contributed document ISO/IEC JTC1/SC29/ +WG1 N 6080 with title "JPEG 9 Lossless Coding", June/July 2012, Paris, +France. + +The JPEG standard does not specify all details of an interchangeable file +format. For the omitted details we follow the "JFIF" conventions, version 2. +JFIF version 1 has been adopted as Recommendation ITU-T T.871 (05/2011) : +Information technology - Digital compression and coding of continuous-tone +still images: JPEG File Interchange Format (JFIF). It is available as a +free download in PDF file format from http://www.itu.int/rec/T-REC-T.871. +A PDF file of the older JFIF document is available at +http://www.w3.org/Graphics/JPEG/jfif3.pdf. + +The TIFF 6.0 file format specification can be obtained by FTP from +ftp://ftp.sgi.com/graphics/tiff/TIFF6.ps.gz. The JPEG incorporation scheme +found in the TIFF 6.0 spec of 3-June-92 has a number of serious problems. +IJG does not recommend use of the TIFF 6.0 design (TIFF Compression tag 6). +Instead, we recommend the JPEG design proposed by TIFF Technical Note #2 +(Compression tag 7). Copies of this Note can be obtained from +http://www.ijg.org/files/. It is expected that the next revision +of the TIFF spec will replace the 6.0 JPEG design with the Note's design. +Although IJG's own code does not support TIFF/JPEG, the free libtiff library +uses our library to implement TIFF/JPEG per the Note. + + +ARCHIVE LOCATIONS +================= + +The "official" archive site for this software is www.ijg.org. +The most recent released version can always be found there in +directory "files".

Lane for the original +design and development of this singular software package. + + +FILE FORMAT WARS +================ + +The ISO/IEC JTC1/SC29/WG1 standards committee (previously known as JPEG, +together with ITU-T SG16) currently promotes different formats containing +the name "JPEG" which is misleading because these formats are incompatible +with original DCT-based JPEG and are based on faulty technologies. +IJG therefore does not and will not support such momentary mistakes +(see REFERENCES). +There exist also distributions under the name "OpenJPEG" promoting such +kind of formats which is misleading because they don't support original +JPEG images. +We have no sympathy for the promotion of inferior formats. Indeed, one of +the original reasons for developing this free software was to help force +convergence on common, interoperable format standards for JPEG files. +Don't use an incompatible file format! +(In any case, our decoder will remain capable of reading existing JPEG +image files indefinitely.) + +The ISO committee pretends to be "responsible for the popular JPEG" in their +public reports which is not true because they don't respond to actual +requirements for the maintenance of the original JPEG specification. +Furthermore, the ISO committee pretends to "ensure interoperability" with +their standards which is not true because their "standards" support only +application-specific and proprietary use cases and contain mathematically +incorrect code. + +There are currently different distributions in circulation containing the +name "libjpeg" which is misleading because they don't have the features and +are incompatible with formats supported by actual IJG libjpeg distributions. +One of those fakes is released by members of the ISO committee and just uses +the name of libjpeg for misdirection of people, similar to the abuse of the +name JPEG as described above, while having nothing in common with actual IJG +libjpeg distributions and containing mathematically incorrect code. +The other one claims to be a "derivative" or "fork" of the original libjpeg, +but violates the license conditions as described under LEGAL ISSUES above +and violates basic C programming properties. +We have no sympathy for the release of misleading, incorrect and illegal +distributions derived from obsolete code bases. +Don't use an obsolete code base! + +According to the UCC (Uniform Commercial Code) law, IJG has the lawful and +legal right to foreclose on certain standardization bodies and other +institutions or corporations that knowingly perform substantial and +systematic deceptive acts and practices, fraud, theft, and damaging of the +value of the people of this planet without their knowing, willing and +intentional consent. +The titles, ownership, and rights of these institutions and all their assets +are now duly secured and held in trust for the free people of this planet. +People of the planet, on every country, may have a financial interest in +the assets of these former principals, agents, and beneficiaries of the +foreclosed institutions and corporations. +IJG asserts what is: that each man, woman, and child has unalienable value +and rights granted and deposited in them by the Creator and not any one of +the people is subordinate to any artificial principality, corporate fiction +or the special interest of another without their appropriate knowing, +willing and intentional consent made by contract or accommodation agreement. +IJG expresses that which already was. +The people have already determined and demanded that public administration +entities, national governments, and their supporting judicial systems must +be fully transparent, accountable, and liable. +IJG has secured the value for all concerned free people of the planet. + +A partial list of foreclosed institutions and corporations ("Hall of Shame") +is currently prepared and will be published later. + + +TO DO +===== + +Version 9 is the second release of a new generation JPEG standard +to overcome the limitations of the original JPEG specification, +and is the first true source reference JPEG codec. +More features are being prepared for coming releases... + +Please send bug reports, offers of help, etc. to jpeg-info@jpegclub.org. diff --git a/project/jni/sdl2_image/external/jpeg-9b/aclocal.m4 b/project/jni/sdl2_image/external/jpeg-9b/aclocal.m4 new file mode 100644 index 000000000..2329dd171 --- /dev/null +++ b/project/jni/sdl2_image/external/jpeg-9b/aclocal.m4 @@ -0,0 +1,10277 @@ +# generated automatically by aclocal 1.15 -*- Autoconf -*- + +# Copyright (C) 1996-2014 Free Software Foundation, Inc. + +# This file is free software; the Free Software Foundation +# gives unlimited permission to copy and/or distribute it, +# with or without modifications, as long as this notice is preserved. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY, to the extent permitted by law; without +# even the implied warranty of MERCHANTABILITY or FITNESS FOR A +# PARTICULAR PURPOSE. + +m4_ifndef([AC_CONFIG_MACRO_DIRS], [m4_defun([_AM_CONFIG_MACRO_DIRS], [])m4_defun([AC_CONFIG_MACRO_DIRS], [_AM_CONFIG_MACRO_DIRS($@)])]) +m4_ifndef([AC_AUTOCONF_VERSION], + [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl +m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.69],, +[m4_warning([this file was generated for autoconf 2.69. +You have another version of autoconf.

A (draft) specification of the JPEG SmartScale extension is +available as a contributed document at ITU and ISO. Revision 2 or later +of the document is required (latest document version is Revision 3). +The SmartScale extension will enable more features beside lossless resize +in future implementations, as described in the document (new compression +options). + +Add sanity check in BMP reader module to avoid cjpeg crash for empty input +image (thank to Isaev Ildar of ISP RAS, Moscow, RU for reporting this error). + +Add data source and destination managers for read from and write to +memory buffers. New API functions jpeg_mem_src and jpeg_mem_dest. +Thank to Roberto Boni from Italy for the suggestion. + + +Version 7 27-Jun-2009 +---------------------- + +New scaled DCTs implemented. +djpeg now supports scalings N/8 with all N from 1 to 16. +cjpeg now supports scalings 8/N with all N from 1 to 16. +Scaled DCTs with size larger than 8 are now also used for resolving the +common 2x2 chroma subsampling case without additional spatial resampling. +Separate spatial resampling for those kind of files is now only necessary +for N>8 scaling cases. +Furthermore, separate scaled DCT functions are provided for direct resolving +of the common asymmetric subsampling cases (2x1 and 1x2) without additional +spatial resampling. + +cjpeg -quality option has been extended for support of separate quality +settings for luminance and chrominance (or in general, for every provided +quantization table slot). +New API function jpeg_default_qtables() and q_scale_factor array in library. + +Added -nosmooth option to cjpeg, complementary to djpeg. +New variable "do_fancy_downsampling" in library, complement to fancy +upsampling. Fancy upsampling now uses direct DCT scaling with sizes +larger than 8. The old method is not reversible and has been removed. + +Support arithmetic entropy encoding and decoding. +Added files jaricom.c, jcarith.c, jdarith.c. + +Straighten the file structure: +Removed files jidctred.c, jcphuff.c, jchuff.h, jdphuff.c, jdhuff.h. + +jpegtran has a new "lossless" cropping feature. + +Implement -perfect option in jpegtran, new API function +jtransform_perfect_transform() in transupp. (DP 204_perfect.dpatch) + +Better error messages for jpegtran fopen failure. +(DP 203_jpegtran_errmsg.dpatch) + +Fix byte order issue with 16bit PPM/PGM files in rdppm.c/wrppm.c: +according to Netpbm, the de facto standard implementation of the PNM formats, +the most significant byte is first. (DP 203_rdppm.dpatch) + +Add -raw option to rdjpgcom not to mangle the output. +(DP 205_rdjpgcom_raw.dpatch) + +Make rdjpgcom locale aware. (DP 201_rdjpgcom_locale.dpatch) + +Add extern "C" to jpeglib.h. +This avoids the need to put extern "C" { ... } around #include "jpeglib.h" +in your C++ application. Defining the symbol DONT_USE_EXTERN_C in the +configuration prevents this. (DP 202_jpeglib.h_c++.dpatch) + + +Version 6b 27-Mar-1998 +----------------------- + +jpegtran has new features for lossless image transformations (rotation +and flipping) as well as "lossless" reduction to grayscale. + +jpegtran now copies comments by default; it has a -copy switch to enable +copying all APPn blocks as well, or to suppress comments. (Formerly it +always suppressed comments and APPn blocks.) jpegtran now also preserves +JFIF version and resolution information. + +New decompressor library feature: COM and APPn markers found in the input +file can be saved in memory for later use by the application. (Before, +you had to code this up yourself with a custom marker processor.) + +There is an unused field "void * client_data" now in compress and decompress +parameter structs; this may be useful in some applications. + +JFIF version number information is now saved by the decoder and accepted by +the encoder. jpegtran uses this to copy the source file's version number, +to ensure "jpegtran -copy all" won't create bogus files that contain JFXX +extensions but claim to be version 1.01. Applications that generate their +own JFXX extension markers also (finally) have a supported way to cause the +encoder to emit JFIF version number 1.02. + +djpeg's trace mode reports JFIF 1.02 thumbnail images as such, rather +than as unknown APP0 markers. + +In -verbose mode, djpeg and rdjpgcom will try to print the contents of +APP12 markers as text. Some digital cameras store useful text information +in APP12 markers. + +Handling of truncated data streams is more robust: blocks beyond the one in +which the error occurs will be output as uniform gray, or left unchanged +if decoding a progressive JPEG. The appearance no longer depends on the +Huffman tables being used. + +Huffman tables are checked for validity much more carefully than before. + +To avoid the Unisys LZW patent, djpeg's GIF output capability has been +changed to produce "uncompressed GIFs", and cjpeg's GIF input capability +has been removed altogether. We're not happy about it either, but there +seems to be no good alternative. + +The configure script now supports building libjpeg as a shared library +on many flavors of Unix (all the ones that GNU libtool knows how to +build shared libraries for). Use "./configure --enable-shared" to +try this out. + +New jconfig file and makefiles for Microsoft Visual C++ and Developer Studio. +Also, a jconfig file and a build script for Metrowerks CodeWarrior +on Apple Macintosh. makefile.dj has been updated for DJGPP v2, and there +are miscellaneous other minor improvements in the makefiles. + +jmemmac.c now knows how to create temporary files following Mac System 7 +conventions. + +djpeg's -map switch is now able to read raw-format PPM files reliably. + +cjpeg -progressive -restart no longer generates any unnecessary DRI markers. + +Multiple calls to jpeg_simple_progression for a single JPEG object +no longer leak memory. + + +Version 6a 7-Feb-96 +-------------------- + +Library initialization sequence modified to detect version mismatches +and struct field packing mismatches between library and calling application. +This change requires applications to be recompiled, but does not require +any application source code change. + +All routine declarations changed to the style "GLOBAL(type) name ...", +that is, GLOBAL, LOCAL, METHODDEF, EXTERN are now macros taking the +routine's return type as an argument. This makes it possible to add +Microsoft-style linkage keywords to all the routines by changing just +these macros. Note that any application code that was using these macros +will have to be changed. + +DCT coefficient quantization tables are now stored in normal array order +rather than zigzag order. Application code that calls jpeg_add_quant_table, +or otherwise manipulates quantization tables directly, will need to be +changed. If you need to make such code work with either older or newer +versions of the library, a test like "#if JPEG_LIB_VERSION >= 61" is +recommended. + +djpeg's trace capability now dumps DQT tables in natural order, not zigzag +order. This allows the trace output to be made into a "-qtables" file +more easily. + +New system-dependent memory manager module for use on Apple Macintosh. + +Fix bug in cjpeg's -smooth option: last one or two scanlines would be +duplicates of the prior line unless the image height mod 16 was 1 or 2. + +Repair minor problems in VMS, BCC, MC6 makefiles. + +New configure script based on latest GNU Autoconf. + +Correct the list of include files needed by MetroWerks C for ccommand(). + +Numerous small documentation updates. + + +Version 6 2-Aug-95 +------------------- + +Progressive JPEG support: library can read and write full progressive JPEG +files. A "buffered image" mode supports incremental decoding for on-the-fly +display of progressive images. Simply recompiling an existing IJG-v5-based +decoder with v6 should allow it to read progressive files, though of course +without any special progressive display. + +New "jpegtran" application performs lossless transcoding between different +JPEG formats; primarily, it can be used to convert baseline to progressive +JPEG and vice versa. In support of jpegtran, the library now allows lossless +reading and writing of JPEG files as DCT coefficient arrays. This ability +may be of use in other applications. + +Notes for programmers: +* We changed jpeg_start_decompress() to be able to suspend; this makes all +decoding modes available to suspending-input applications. However, +existing applications that use suspending input will need to be changed +to check the return value from jpeg_start_decompress(). You don't need to +do anything if you don't use a suspending data source. +* We changed the interface to the virtual array routines: access_virt_array +routines now take a count of the number of rows to access this time. The +last parameter to request_virt_array routines is now interpreted as the +maximum number of rows that may be accessed at once, but not necessarily +the height of every access. + + +Version 5b 15-Mar-95 +--------------------- + +Correct bugs with grayscale images having v_samp_factor > 1. + +jpeg_write_raw_data() now supports output suspension. + +Correct bugs in "configure" script for case of compiling in +a directory other than the one containing the source files. + +Repair bug in jquant1.c: sometimes didn't use as many colors as it could. + +Borland C makefile and jconfig file work under either MS-DOS or OS/2. + +Miscellaneous improvements to documentation. + + +Version 5a 7-Dec-94 +-------------------- + +Changed color conversion roundoff behavior so that grayscale values are +represented exactly. (This causes test image files to change.) + +Make ordered dither use 16x16 instead of 4x4 pattern for a small quality +improvement. + +New configure script based on latest GNU Autoconf. +Fix configure script to handle CFLAGS correctly. +Rename *.auto files to *.cfg, so that configure script still works if +file names have been truncated for DOS. + +Fix bug in rdbmp.c: didn't allow for extra data between header and image. + +Modify rdppm.c/wrppm.c to handle 2-byte raw PPM/PGM formats for 12-bit data. + +Fix several bugs in rdrle.c. + +NEED_SHORT_EXTERNAL_NAMES option was broken. + +Revise jerror.h/jerror.c for more flexibility in message table. + +Repair oversight in jmemname.c NO_MKTEMP case: file could be there +but unreadable. + + +Version 5 24-Sep-94 +-------------------- + +Version 5 represents a nearly complete redesign and rewrite of the IJG +software. Major user-visible changes include: + * Automatic configuration simplifies installation for most Unix systems. + * A range of speed vs. image quality tradeoffs are supported. + This includes resizing of an image during decompression: scaling down + by a factor of 1/2, 1/4, or 1/8 is handled very efficiently. + * New programs rdjpgcom and wrjpgcom allow insertion and extraction + of text comments in a JPEG file. + +The application programmer's interface to the library has changed completely. +Notable improvements include: + * We have eliminated the use of callback routines for handling the + uncompressed image data. The application now sees the library as a + set of routines that it calls to read or write image data on a + scanline-by-scanline basis. + * The application image data is represented in a conventional interleaved- + pixel format, rather than as a separate array for each color channel. + This can save a copying step in many programs. + * The handling of compressed data has been cleaned up: the application can + supply routines to source or sink the compressed data. It is possible to + suspend processing on source/sink buffer overrun, although this is not + supported in all operating modes. + * All static state has been eliminated from the library, so that multiple + instances of compression or decompression can be active concurrently. + * JPEG abbreviated datastream formats are supported, ie, quantization and + Huffman tables can be stored separately from the image data. + * And not only that, but the documentation of the library has improved + considerably! + + +The last widely used release before the version 5 rewrite was version 4A of +18-Feb-93. Change logs before that point have been discarded, since they +are not of much interest after the rewrite. diff --git a/project/jni/sdl2_image/external/jpeg-9b/cjpeg.1 b/project/jni/sdl2_image/external/jpeg-9b/cjpeg.1 new file mode 100644 index 000000000..7d685be58 --- /dev/null +++ b/project/jni/sdl2_image/external/jpeg-9b/cjpeg.1 @@ -0,0 +1,387 @@ +.TH CJPEG 1 "26 July 2015" +.SH NAME +cjpeg \- compress an image file to a JPEG file +.SH SYNOPSIS +.B cjpeg +[ +.I options +] +[ +.I filename +] +.LP +.SH DESCRIPTION +.LP +.B cjpeg +compresses the named image file, or the standard input if no file is +named, and produces a JPEG/JFIF file on the standard output. +The currently supported input file formats are: PPM (PBMPLUS color +format), PGM (PBMPLUS grayscale format), BMP, Targa, and RLE (Utah Raster +Toolkit format). (RLE is supported only if the URT library is available.) +.SH OPTIONS +All switch names may be abbreviated; for example, +.B \-grayscale +may be written +.B \-gray +or +.BR \-gr . +Most of the "basic" switches can be abbreviated to as little as one letter. +Upper and lower case are equivalent (thus +.B \-BMP +is the same as +.BR \-bmp ). +British spellings are also accepted (e.g., +.BR \-greyscale ), +though for brevity these are not mentioned below. +.PP +The basic switches are: +.TP +.BI \-quality " N[,...]" +Scale quantization tables to adjust image quality. Quality is 0 (worst) to +100 (best); default is 75. (See below for more info.) +.TP +.B \-grayscale +Create monochrome JPEG file from color input. Be sure to use this switch when +compressing a grayscale BMP file, because +.B cjpeg +isn't bright enough to notice whether a BMP file uses only shades of gray. +By saying +.BR \-grayscale , +you'll get a smaller JPEG file that takes less time to process. +.TP +.B \-rgb +Create RGB JPEG file. +Using this switch suppresses the conversion from RGB +colorspace input to the default YCbCr JPEG colorspace. +You can use this switch in combination with the +.BI \-block " N" +switch (see below) for lossless JPEG coding. +See also the +.B \-rgb1 +switch below. +.TP +.B \-optimize +Perform optimization of entropy encoding parameters. Without this, default +encoding parameters are used. +.B \-optimize +usually makes the JPEG file a little smaller, but +.B cjpeg +runs somewhat slower and needs much more memory. Image quality and speed of +decompression are unaffected by +.BR \-optimize . +.TP +.B \-progressive +Create progressive JPEG file (see below). +.TP +.BI \-scale " M/N" +Scale the output image by a factor M/N. Currently supported scale factors are +M/N with all N from 1 to 16, where M is the destination DCT size, which is 8 +by default (see +.BI \-block " N" +switch below). +.TP +.B \-targa +Input file is Targa format. Targa files that contain an "identification" +field will not be automatically recognized by +.BR cjpeg ; +for such files you must specify +.B \-targa +to make +.B cjpeg +treat the input as Targa format. +For most Targa files, you won't need this switch. +.PP +The +.B \-quality +switch lets you trade off compressed file size against quality of the +reconstructed image: the higher the quality setting, the larger the JPEG file, +and the closer the output image will be to the original input. Normally you +want to use the lowest quality setting (smallest file) that decompresses into +something visually indistinguishable from the original image. For this +purpose the quality setting should be between 50 and 95; the default of 75 is +often about right. If you see defects at +.B \-quality +75, then go up 5 or 10 counts at a time until you are happy with the output +image. (The optimal setting will vary from one image to another.) +.PP +.B \-quality +100 will generate a quantization table of all 1's, minimizing loss in the +quantization step (but there is still information loss in subsampling, as well +as roundoff error). This setting is mainly of interest for experimental +purposes. Quality values above about 95 are +.B not +recommended for normal use; the compressed file size goes up dramatically for +hardly any gain in output image quality. +.PP +In the other direction, quality values below 50 will produce very small files +of low image quality. Settings around 5 to 10 might be useful in preparing an +index of a large image library, for example. Try +.B \-quality +2 (or so) for some amusing Cubist effects. (Note: quality +values below about 25 generate 2-byte quantization tables, which are +considered optional in the JPEG standard. +.B cjpeg +emits a warning message when you give such a quality value, because some +other JPEG programs may be unable to decode the resulting file. Use +.B \-baseline +if you need to ensure compatibility at low quality values.) +.PP +The +.B \-quality +option has been extended in IJG version 7 for support of separate quality +settings for luminance and chrominance (or in general, for every provided +quantization table slot). This feature is useful for high-quality +applications which cannot accept the damage of color data by coarse +subsampling settings. You can now easily reduce the color data amount more +smoothly with finer control without separate subsampling. The resulting file +is fully compliant with standard JPEG decoders. +Note that the +.B \-quality +ratings refer to the quantization table slots, and that the last value is +replicated if there are more q-table slots than parameters. The default +q-table slots are 0 for luminance and 1 for chrominance with default tables as +given in the JPEG standard. This is compatible with the old behaviour in case +that only one parameter is given, which is then used for both luminance and +chrominance (slots 0 and 1). More or custom quantization tables can be set +with +.B \-qtables +and assigned to components with +.B \-qslots +parameter (see the "wizard" switches below). +.B Caution: +You must explicitly add +.BI \-sample " 1x1" +for efficient separate color +quality selection, since the default value used by library is 2x2! +.PP +The +.B \-progressive +switch creates a "progressive JPEG" file. In this type of JPEG file, the data +is stored in multiple scans of increasing quality. If the file is being +transmitted over a slow communications link, the decoder can use the first +scan to display a low-quality image very quickly, and can then improve the +display with each subsequent scan. The final image is exactly equivalent to a +standard JPEG file of the same quality setting, and the total file size is +about the same --- often a little smaller. +.PP +Switches for advanced users: +.TP +.B \-arithmetic +Use arithmetic coding. +.B Caution: +arithmetic coded JPEG is not yet widely implemented, so many decoders will +be unable to view an arithmetic coded JPEG file at all. +.TP +.BI \-block " N" +Set DCT block size. All N from 1 to 16 are possible. +Default is 8 (baseline format). +Larger values produce higher compression, +smaller values produce higher quality +(exact DCT stage possible with 1 or 2; with the default quality of 75 and +default Luminance qtable the DCT+Quantization stage is lossless for N=1). +.B Caution: +An implementation of the JPEG SmartScale extension is required for this +feature. SmartScale enabled JPEG is not yet widely implemented, so many +decoders will be unable to view a SmartScale extended JPEG file at all. +.TP +.B \-rgb1 +Create RGB JPEG file with reversible color transform. +Works like the +.B \-rgb +switch (see above) and inserts a simple reversible color transform +into the processing which significantly improves the compression. +Use this switch in combination with the +.BI \-block " N" +switch (see above) for lossless JPEG coding. +.B Caution: +A decoder with inverse color transform support is required for +this feature. Reversible color transform support is not yet +widely implemented, so many decoders will be unable to view +a reversible color transformed JPEG file at all. +.TP +.B \-bgycc +Create big gamut YCC JPEG file. +In this type of encoding the color difference components are quantized +further by a factor of 2 compared to the normal Cb/Cr values, thus creating +space to allow larger color values with higher saturation than the normal +gamut limits to be encoded. In order to compensate for the loss of color +fidelity compared to a normal YCC encoded file, the color quantization +tables can be adjusted accordingly. For example, +.B cjpeg \-bgycc \-quality +80,90 will give similar results as +.B cjpeg \-quality +80. +.B Caution: +For correct decompression a decoder with big gamut YCC support (JFIF +version 2) is required. An old decoder may or may not display a big +gamut YCC encoded JPEG file, depending on JFIF version check and +corresponding warning/error configuration. In case of a granted +decompression the old decoder will display the image with half +saturated colors. +.TP +.B \-dct int +Use integer DCT method (default). +.TP +.B \-dct fast +Use fast integer DCT (less accurate). +.TP +.B \-dct float +Use floating-point DCT method. +The float method is very slightly more accurate than the int method, but is +much slower unless your machine has very fast floating-point hardware. Also +note that results of the floating-point method may vary slightly across +machines, while the integer methods should give the same results everywhere. +The fast integer method is much less accurate than the other two. +.TP +.B \-nosmooth +Don't use high-quality downsampling. +.TP +.BI \-restart " N" +Emit a JPEG restart marker every N MCU rows, or every N MCU blocks if "B" is +attached to the number. +.B \-restart 0 +(the default) means no restart markers. +.TP +.BI \-smooth " N" +Smooth the input image to eliminate dithering noise. N, ranging from 1 to +100, indicates the strength of smoothing. 0 (the default) means no smoothing. +.TP +.BI \-maxmemory " N" +Set limit for amount of memory to use in processing large images. Value is +in thousands of bytes, or millions of bytes if "M" is attached to the +number. For example, +.B \-max 4m +selects 4000000 bytes. If more space is needed, temporary files will be used. +.TP +.BI \-outfile " name" +Send output image to the named file, not to standard output. +.TP +.B \-verbose +Enable debug printout. More +.BR \-v 's +give more output. Also, version information is printed at startup. +.TP +.B \-debug +Same as +.BR \-verbose . +.PP +The +.B \-restart +option inserts extra markers that allow a JPEG decoder to resynchronize after +a transmission error. Without restart markers, any damage to a compressed +file will usually ruin the image from the point of the error to the end of the +image; with restart markers, the damage is usually confined to the portion of +the image up to the next restart marker. Of course, the restart markers +occupy extra space. We recommend +.B \-restart 1 +for images that will be transmitted across unreliable networks such as Usenet. +.PP +The +.B \-smooth +option filters the input to eliminate fine-scale noise. This is often useful +when converting dithered images to JPEG: a moderate smoothing factor of 10 to +50 gets rid of dithering patterns in the input file, resulting in a smaller +JPEG file and a better-looking image. Too large a smoothing factor will +visibly blur the image, however. +.PP +Switches for wizards: +.TP +.B \-baseline +Force baseline-compatible quantization tables to be generated. This clamps +quantization values to 8 bits even at low quality settings. (This switch is +poorly named, since it does not ensure that the output is actually baseline +JPEG. For example, you can use +.B \-baseline +and +.B \-progressive +together.) +.TP +.BI \-qtables " file" +Use the quantization tables given in the specified text file. +.TP +.BI \-qslots " N[,...]" +Select which quantization table to use for each color component. +.TP +.BI \-sample " HxV[,...]" +Set JPEG sampling factors for each color component. +.TP +.BI \-scans " file" +Use the scan script given in the specified text file. +.PP +The "wizard" switches are intended for experimentation with JPEG. If you +don't know what you are doing, \fBdon't use them\fR. These switches are +documented further in the file wizard.txt. +.SH EXAMPLES +.LP +This example compresses the PPM file foo.ppm with a quality factor of +60 and saves the output as foo.jpg: +.IP +.B cjpeg \-quality +.I 60 foo.ppm +.B > +.I foo.jpg +.SH HINTS +Color GIF files are not the ideal input for JPEG; JPEG is really intended for +compressing full-color (24-bit) images. In particular, don't try to convert +cartoons, line drawings, and other images that have only a few distinct +colors. GIF works great on these, JPEG does not. If you want to convert a +GIF to JPEG, you should experiment with +.BR cjpeg 's +.B \-quality +and +.B \-smooth +options to get a satisfactory conversion. +.B \-smooth 10 +or so is often helpful. +.PP +Avoid running an image through a series of JPEG compression/decompression +cycles. Image quality loss will accumulate; after ten or so cycles the image +may be noticeably worse than it was after one cycle. It's best to use a +lossless format while manipulating an image, then convert to JPEG format when +you are ready to file the image away. +.PP +The +.B \-optimize +option to +.B cjpeg +is worth using when you are making a "final" version for posting or archiving. +It's also a win when you are using low quality settings to make very small +JPEG files; the percentage improvement is often a lot more than it is on +larger files. (At present, +.B \-optimize +mode is always selected when generating progressive JPEG files.) +.SH ENVIRONMENT +.TP +.B JPEGMEM +If this environment variable is set, its value is the default memory limit. +The value is specified as described for the +.B \-maxmemory +switch. +.B JPEGMEM +overrides the default value specified when the program was compiled, and +itself is overridden by an explicit +.BR \-maxmemory . +.SH SEE ALSO +.BR djpeg (1), +.BR jpegtran (1), +.BR rdjpgcom (1), +.BR wrjpgcom (1) +.br +.BR ppm (5), +.BR pgm (5) +.br +Wallace, Gregory K.

Lane. +This file is part of the Independent JPEG Group's software. +For conditions of distribution and use, see the accompanying README file. + + +Since numerous people will be contributing code and bug fixes, it's important +to establish a common coding style. The goal of using similar coding styles +is much more important than the details of just what that style is. + +In general we follow the recommendations of "Recommended C Style and Coding +Standards" revision 6.1 (Cannon et al. as modified by Spencer, Keppel and +Brader). This document is available in the IJG FTP archive (see +jpeg/doc/cstyle.ms.tbl.Z, or cstyle.txt.Z for those without nroff/tbl). + +Block comments should be laid out thusly: + +/* + * Block comments in this style. + */ + +We indent statements in K&R style, e.g., + if (test) { + then-part; + } else { + else-part; + } +with two spaces per indentation level. (This indentation convention is +handled automatically by GNU Emacs and many other text editors.) + +Multi-word names should be written in lower case with underscores, e.g., +multi_word_name (not multiWordName). Preprocessor symbols and enum constants +are similar but upper case (MULTI_WORD_NAME). Names should be unique within +the first fifteen characters. (On some older systems, global names must be +unique within six characters. We accommodate this without cluttering the +source code by using macros to substitute shorter names.) + +We use function prototypes everywhere; we rely on automatic source code +transformation to feed prototype-less C compilers. Transformation is done +by the simple and portable tool 'ansi2knr.c' (courtesy of Ghostscript). +ansi2knr is not very bright, so it imposes a format requirement on function +declarations: the function name MUST BEGIN IN COLUMN 1. Thus all functions +should be written in the following style: + +LOCAL(int *) +function_name (int a, char *b) +{ + code... +} + +Note that each function definition must begin with GLOBAL(type), LOCAL(type), +or METHODDEF(type). These macros expand to "static type" or just "type" as +appropriate. They provide a readable indication of the routine's usage and +can readily be changed for special needs. (For instance, special linkage +keywords can be inserted for use in Windows DLLs.) + +ansi2knr does not transform method declarations (function pointers in +structs). We handle these with a macro JMETHOD, defined as + #ifdef HAVE_PROTOTYPES + #define JMETHOD(type,methodname,arglist) type (*methodname) arglist + #else + #define JMETHOD(type,methodname,arglist) type (*methodname) () + #endif +which is used like this: + struct function_pointers { + JMETHOD(void, init_entropy_encoder, (int somearg, jparms *jp)); + JMETHOD(void, term_entropy_encoder, (void)); + }; +Note the set of parentheses surrounding the parameter list. + +A similar solution is used for forward and external function declarations +(see the EXTERN and JPP macros). + +If the code is to work on non-ANSI compilers, we cannot rely on a prototype +declaration to coerce actual parameters into the right types. Therefore, use +explicit casts on actual parameters whenever the actual parameter type is not +identical to the formal parameter. Beware of implicit conversions to "int". + +It seems there are some non-ANSI compilers in which the sizeof() operator +is defined to return int, yet size_t is defined as long. Needless to say, +this is brain-damaged. Always use the SIZEOF() macro in place of sizeof(), +so that the result is guaranteed to be of type size_t. + + +The JPEG library is intended to be used within larger programs. Furthermore, +we want it to be reentrant so that it can be used by applications that process +multiple images concurrently. The following rules support these requirements: + +1. Avoid direct use of file I/O, "malloc", error report printouts, etc; +pass these through the common routines provided. + +2. Minimize global namespace pollution. Functions should be declared static +wherever possible. (Note that our method-based calling conventions help this +a lot: in many modules only the initialization function will ever need to be +called directly, so only that function need be externally visible.) All +global function names should begin with "jpeg_", and should have an +abbreviated name (unique in the first six characters) substituted by macro +when NEED_SHORT_EXTERNAL_NAMES is set. + +3. Don't use global variables; anything that must be used in another module +should be in the common data structures. + +4. Don't use static variables except for read-only constant tables. Variables +that should be private to a module can be placed into private structures (see +the system architecture document, structure.txt). + +5. Source file names should begin with "j" for files that are part of the +library proper; source files that are not part of the library, such as cjpeg.c +and djpeg.c, do not begin with "j". Keep source file names to eight +characters (plus ".c" or ".h", etc) to make life easy for MS-DOSers. Keep +compression and decompression code in separate source files --- some +applications may want only one half of the library. + +Note: these rules (particularly #4) are not followed religiously in the +modules that are used in cjpeg/djpeg but are not part of the JPEG library +proper. Those modules are not really intended to be used in other +applications. diff --git a/project/jni/sdl2_image/external/jpeg-9b/compile b/project/jni/sdl2_image/external/jpeg-9b/compile new file mode 100755 index 000000000..a85b723c7 --- /dev/null +++ b/project/jni/sdl2_image/external/jpeg-9b/compile @@ -0,0 +1,347 @@ +#! /bin/sh +# Wrapper for compilers which do not understand '-c -o'. + +scriptversion=2012-10-14.11; # UTC + +# Copyright (C) 1999-2014 Free Software Foundation, Inc. +# Written by Tom Tromey . +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2, or (at your option) +# any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

PBMPLUS (PPM/PGM), BMP, +GIF, Targa, or RLE (Utah Raster Toolkit) output format can be selected. +(RLE is supported only if the URT library is available.) +.SH OPTIONS +All switch names may be abbreviated; for example, +.B \-grayscale +may be written +.B \-gray +or +.BR \-gr . +Most of the "basic" switches can be abbreviated to as little as one letter. +Upper and lower case are equivalent (thus +.B \-BMP +is the same as +.BR \-bmp ). +British spellings are also accepted (e.g., +.BR \-greyscale ), +though for brevity these are not mentioned below. +.PP +The basic switches are: +.TP +.BI \-colors " N" +Reduce image to at most N colors. This reduces the number of colors used in +the output image, so that it can be displayed on a colormapped display or +stored in a colormapped file format. For example, if you have an 8-bit +display, you'd need to reduce to 256 or fewer colors. +.TP +.BI \-quantize " N" +Same as +.BR \-colors . +.B \-colors +is the recommended name, +.B \-quantize +is provided only for backwards compatibility. +.TP +.B \-fast +Select recommended processing options for fast, low quality output. (The +default options are chosen for highest quality output.) Currently, this is +equivalent to \fB\-dct fast \-nosmooth \-onepass \-dither ordered\fR. +.TP +.B \-grayscale +Force grayscale output even if JPEG file is color. +Useful for viewing on monochrome displays; also, +.B djpeg +runs noticeably faster in this mode. +.TP +.B \-rgb +Force RGB output even if JPEG file is grayscale. +This is provided to support applications that don't +want to cope with grayscale as a separate case. +.TP +.BI \-scale " M/N" +Scale the output image by a factor M/N. Currently supported scale factors are +M/N with all M from 1 to 16, where N is the source DCT size, which is 8 for +baseline JPEG. If the /N part is omitted, then M specifies the DCT scaled +size to be applied on the given input. For baseline JPEG this is equivalent +to M/8 scaling, since the source DCT size for baseline JPEG is 8. +Scaling is handy if the image is larger than your screen; also, +.B djpeg +runs much faster when scaling down the output. +.TP +.B \-bmp +Select BMP output format (Windows flavor). 8-bit colormapped format is +emitted if +.B \-colors +or +.B \-grayscale +is specified, or if the JPEG file is grayscale; otherwise, 24-bit full-color +format is emitted. +.TP +.B \-gif +Select GIF output format. Since GIF does not support more than 256 colors, +.B \-colors 256 +is assumed (unless you specify a smaller number of colors). +.TP +.B \-os2 +Select BMP output format (OS/2 1.x flavor). 8-bit colormapped format is +emitted if +.B \-colors +or +.B \-grayscale +is specified, or if the JPEG file is grayscale; otherwise, 24-bit full-color +format is emitted. +.TP +.B \-pnm +Select PBMPLUS (PPM/PGM) output format (this is the default format). +PGM is emitted if the JPEG file is grayscale or if +.B \-grayscale +is specified; otherwise PPM is emitted. +.TP +.B \-rle +Select RLE output format. (Requires URT library.) +.TP +.B \-targa +Select Targa output format. Grayscale format is emitted if the JPEG file is +grayscale or if +.B \-grayscale +is specified; otherwise, colormapped format is emitted if +.B \-colors +is specified; otherwise, 24-bit full-color format is emitted. +.PP +Switches for advanced users: +.TP +.B \-dct int +Use integer DCT method (default). +.TP +.B \-dct fast +Use fast integer DCT (less accurate). +.TP +.B \-dct float +Use floating-point DCT method. +The float method is very slightly more accurate than the int method, but is +much slower unless your machine has very fast floating-point hardware. Also +note that results of the floating-point method may vary slightly across +machines, while the integer methods should give the same results everywhere. +The fast integer method is much less accurate than the other two. +.TP +.B \-dither fs +Use Floyd-Steinberg dithering in color quantization. +.TP +.B \-dither ordered +Use ordered dithering in color quantization. +.TP +.B \-dither none +Do not use dithering in color quantization. +By default, Floyd-Steinberg dithering is applied when quantizing colors; this +is slow but usually produces the best results. Ordered dither is a compromise +between speed and quality; no dithering is fast but usually looks awful. Note +that these switches have no effect unless color quantization is being done. +Ordered dither is only available in +.B \-onepass +mode. +.TP +.BI \-map " file" +Quantize to the colors used in the specified image file. This is useful for +producing multiple files with identical color maps, or for forcing a +predefined set of colors to be used. The +.I file +must be a GIF or PPM file. This option overrides +.B \-colors +and +.BR \-onepass . +.TP +.B \-nosmooth +Don't use high-quality upsampling. +.TP +.B \-onepass +Use one-pass instead of two-pass color quantization. The one-pass method is +faster and needs less memory, but it produces a lower-quality image. +.B \-onepass +is ignored unless you also say +.B \-colors +.IR N . +Also, the one-pass method is always used for grayscale output (the two-pass +method is no improvement then). +.TP +.BI \-maxmemory " N" +Set limit for amount of memory to use in processing large images. Value is +in thousands of bytes, or millions of bytes if "M" is attached to the +number. For example, +.B \-max 4m +selects 4000000 bytes. If more space is needed, temporary files will be used. +.TP +.BI \-outfile " name" +Send output image to the named file, not to standard output. +.TP +.B \-verbose +Enable debug printout. More +.BR \-v 's +give more output. Also, version information is printed at startup. +.TP +.B \-debug +Same as +.BR \-verbose . +.SH EXAMPLES +.LP +This example decompresses the JPEG file foo.jpg, quantizes it to +256 colors, and saves the output in 8-bit BMP format in foo.bmp: +.IP +.B djpeg \-colors 256 \-bmp +.I foo.jpg +.B > +.I foo.bmp +.SH HINTS +To get a quick preview of an image, use the +.B \-grayscale +and/or +.B \-scale +switches. +.B \-grayscale \-scale 1/8 +is the fastest case. +.PP +Several options are available that trade off image quality to gain speed. +.B \-fast +turns on the recommended settings. +.PP +.B \-dct fast +and/or +.B \-nosmooth +gain speed at a small sacrifice in quality. +When producing a color-quantized image, +.B \-onepass \-dither ordered +is fast but much lower quality than the default behavior. +.B \-dither none +may give acceptable results in two-pass mode, but is seldom tolerable in +one-pass mode. +.PP +If you are fortunate enough to have very fast floating point hardware, +\fB\-dct float\fR may be even faster than \fB\-dct fast\fR.

Lane, Guido Vollbeding. +This file is part of the Independent JPEG Group's software. +For conditions of distribution and use, see the accompanying README file. + + +This file explains how to configure and install the IJG software. We have +tried to make this software extremely portable and flexible, so that it can be +adapted to almost any environment. The downside of this decision is that the +installation process is complicated. We have provided shortcuts to simplify +the task on common systems. But in any case, you will need at least a little +familiarity with C programming and program build procedures for your system. + +If you are only using this software as part of a larger program, the larger +program's installation procedure may take care of configuring the IJG code. +For example, Ghostscript's installation script will configure the IJG code. +You don't need to read this file if you just want to compile Ghostscript. + +If you are on a Unix machine, you may not need to read this file at all. +Try doing + ./configure + make + make test +If that doesn't complain, do + make install +(better do "make -n install" first to see if the makefile will put the files +where you want them). Read further if you run into snags or want to customize +the code for your system. + + +TABLE OF CONTENTS +----------------- + +Before you start +Configuring the software: + using the automatic "configure" script + using one of the supplied jconfig and makefile files + by hand +Building the software +Testing the software +Installing the software +Optional stuff +Optimization +Hints for specific systems + + +BEFORE YOU START +================ + +Before installing the software you must unpack the distributed source code. +Since you are reading this file, you have probably already succeeded in this +task. However, there is a potential for error if you needed to convert the +files to the local standard text file format (for example, if you are on +MS-DOS you may have converted LF end-of-line to CR/LF). You must apply +such conversion to all the files EXCEPT those whose names begin with "test". +The test files contain binary data; if you change them in any way then the +self-test will give bad results. + +Please check the last section of this file to see if there are hints for the +specific machine or compiler you are using. + + +CONFIGURING THE SOFTWARE +======================== + +To configure the IJG code for your system, you need to create two files: + * jconfig.h: contains values for system-dependent #define symbols. + * Makefile: controls the compilation process. +(On a non-Unix machine, you may create "project files" or some other +substitute for a Makefile. jconfig.h is needed in any environment.) + +We provide three different ways to generate these files: + * On a Unix system, you can just run the "configure" script. + * We provide sample jconfig files and makefiles for popular machines; + if your machine matches one of the samples, just copy the right sample + files to jconfig.h and Makefile. + * If all else fails, read the instructions below and make your own files. + + +Configuring the software using the automatic "configure" script +--------------------------------------------------------------- + +If you are on a Unix machine, you can just type + ./configure +and let the configure script construct appropriate configuration files. +If you're using "csh" on an old version of System V, you might need to type + sh configure +instead to prevent csh from trying to execute configure itself. +Expect configure to run for a few minutes, particularly on slower machines; +it works by compiling a series of test programs. + +Configure was created with GNU Autoconf and it follows the usual conventions +for GNU configure scripts. It makes a few assumptions that you may want to +override. You can do this by providing optional switches to configure: + +* Configure will build both static and shared libraries, if possible. +If you want to build libjpeg only as a static library, say + ./configure --disable-shared +If you want to build libjpeg only as a shared library, say + ./configure --disable-static +Configure uses GNU libtool to take care of system-dependent shared library +building methods. + +* Configure will use gcc (GNU C compiler) if it's available, otherwise cc. +To force a particular compiler to be selected, use the CC option, for example + ./configure CC='cc' +The same method can be used to include any unusual compiler switches. +For example, on HP-UX you probably want to say + ./configure CC='cc -Aa' +to get HP's compiler to run in ANSI mode. + +* The default CFLAGS setting is "-g" for non-gcc compilers, "-g -O2" for gcc. +You can override this by saying, for example, + ./configure CFLAGS='-O2' +if you want to compile without debugging support. + +* Configure will set up the makefile so that "make install" will install files +into /usr/local/bin, /usr/local/man, etc. You can specify an installation +prefix other than "/usr/local" by giving configure the option "--prefix=PATH". + +* If you don't have a lot of swap space, you may need to enable the IJG +software's internal virtual memory mechanism. To do this, give the option +"--enable-maxmem=N" where N is the default maxmemory limit in megabytes. +This is discussed in more detail under "Selecting a memory manager", below. +You probably don't need to worry about this on reasonably-sized Unix machines, +unless you plan to process very large images. + +Configure has some other features that are useful if you are cross-compiling +or working in a network of multiple machine types; but if you need those +features, you probably already know how to use them. + + +Configuring the software using one of the supplied jconfig and makefile files +----------------------------------------------------------------------------- + +If you have one of these systems, you can just use the provided configuration +files: + +Makefile jconfig file System and/or compiler + +makefile.manx jconfig.manx Amiga, Manx Aztec C +makefile.sas jconfig.sas Amiga, SAS C +makeproj.mac jconfig.mac Apple Macintosh, Metrowerks CodeWarrior +mak*jpeg.st jconfig.st Atari ST/STE/TT, Pure C or Turbo C +makefile.bcc jconfig.bcc MS-DOS or OS/2, Borland C +makefile.dj jconfig.dj MS-DOS, DJGPP (Delorie's port of GNU C) +makefile.mc6 jconfig.mc6 MS-DOS, Microsoft C (16-bit only) +makefile.wat jconfig.wat MS-DOS, OS/2, or Windows NT, Watcom C +makefile.vc jconfig.vc Windows NT/9x, MS Visual C++ +make*.vc6 jconfig.vc Windows NT/9x, MS Visual C++ 6 +make*.v10 jconfig.vc Windows NT/9x, MS Visual C++ 2010 (v10) +makefile.b32 jconfig.vc Windows NT/9x, Borland C++ 32-bit (bcc32) +makefile.mms jconfig.vms Digital VMS, with MMS software +makefile.vms jconfig.vms Digital VMS, without MMS software + +Copy the proper jconfig file to jconfig.h and the makefile to Makefile (or +whatever your system uses as the standard makefile name). For more info see +the appropriate system-specific hints section near the end of this file. + + +Configuring the software by hand +-------------------------------- + +First, generate a jconfig.h file. If you are moderately familiar with C, +the comments in jconfig.txt should be enough information to do this; just +copy jconfig.txt to jconfig.h and edit it appropriately. Otherwise, you may +prefer to use the ckconfig.c program. You will need to compile and execute +ckconfig.c by hand --- we hope you know at least enough to do that. +ckconfig.c may not compile the first try (in fact, the whole idea is for it +to fail if anything is going to). If you get compile errors, fix them by +editing ckconfig.c according to the directions given in ckconfig.c. Once +you get it to run, it will write a suitable jconfig.h file, and will also +print out some advice about which makefile to use. + +You may also want to look at the canned jconfig files, if there is one for a +system similar to yours. + +Second, select a makefile and copy it to Makefile (or whatever your system +uses as the standard makefile name). The most generic makefiles we provide +are + makefile.ansi: if your C compiler supports function prototypes + makefile.unix: if not. +(You have function prototypes if ckconfig.c put "#define HAVE_PROTOTYPES" +in jconfig.h.) You may want to start from one of the other makefiles if +there is one for a system similar to yours. + +Look over the selected Makefile and adjust options as needed. In particular +you may want to change the CC and CFLAGS definitions. For instance, if you +are using GCC, set CC=gcc. If you had to use any compiler switches to get +ckconfig.c to work, make sure the same switches are in CFLAGS. + +If you are on a system that doesn't use makefiles, you'll need to set up +project files (or whatever you do use) to compile all the source files and +link them into executable files cjpeg, djpeg, jpegtran, rdjpgcom, and wrjpgcom. +See the file lists in any of the makefiles to find out which files go into +each program. Note that the provided makefiles all make a "library" file +libjpeg first, but you don't have to do that if you don't want to; the file +lists identify which source files are actually needed for compression, +decompression, or both. As a last resort, you can make a batch script that +just compiles everything and links it all together; makefile.vms is an example +of this (it's for VMS systems that have no make-like utility). + +Here are comments about some specific configuration decisions you'll +need to make: + +Command line style +------------------ + +These programs can use a Unix-like command line style which supports +redirection and piping, like this: + cjpeg inputfile >outputfile + cjpeg outputfile + source program | cjpeg >outputfile +The simpler "two file" command line style is just + cjpeg inputfile outputfile +You may prefer the two-file style, particularly if you don't have pipes. + +You MUST use two-file style on any system that doesn't cope well with binary +data fed through stdin/stdout; this is true for some MS-DOS compilers, for +example. If you're not on a Unix system, it's safest to assume you need +two-file style. (But if your compiler provides either the Posix-standard +fdopen() library routine or a Microsoft-compatible setmode() routine, you +can safely use the Unix command line style, by defining USE_FDOPEN or +USE_SETMODE respectively.) + +To use the two-file style, make jconfig.h say "#define TWO_FILE_COMMANDLINE". + +Selecting a memory manager +-------------------------- + +The IJG code is capable of working on images that are too big to fit in main +memory; data is swapped out to temporary files as necessary. However, the +code to do this is rather system-dependent. We provide five different +memory managers: + +* jmemansi.c This version uses the ANSI-standard library routine tmpfile(), + which not all non-ANSI systems have. On some systems + tmpfile() may put the temporary file in a non-optimal + location; if you don't like what it does, use jmemname.c. + +* jmemname.c This version creates named temporary files. For anything + except a Unix machine, you'll need to configure the + select_file_name() routine appropriately; see the comments + near the head of jmemname.c. If you use this version, define + NEED_SIGNAL_CATCHER in jconfig.h to make sure the temp files + are removed if the program is aborted. + +* jmemnobs.c (That stands for No Backing Store :-).) This will compile on + almost any system, but it assumes you have enough main memory + or virtual memory to hold the biggest images you work with. + +* jmemdos.c This should be used with most 16-bit MS-DOS compilers. + See the system-specific notes about MS-DOS for more info. + IMPORTANT: if you use this, define USE_MSDOS_MEMMGR in + jconfig.h, and include the assembly file jmemdosa.asm in the + programs. The supplied makefiles and jconfig files for + 16-bit MS-DOS compilers already do both. + +* jmemmac.c Custom version for Apple Macintosh; see the system-specific + notes for Macintosh for more info. + +To use a particular memory manager, change the SYSDEPMEM variable in your +makefile to equal the corresponding object file name (for example, jmemansi.o +or jmemansi.obj for jmemansi.c). + +If you have plenty of (real or virtual) main memory, just use jmemnobs.c. +"Plenty" means about ten bytes for every pixel in the largest images +you plan to process, so a lot of systems don't meet this criterion. +If yours doesn't, try jmemansi.c first. If that doesn't compile, you'll have +to use jmemname.c; be sure to adjust select_file_name() for local conditions. +You may also need to change unlink() to remove() in close_backing_store(). + +Except with jmemnobs.c or jmemmac.c, you need to adjust the DEFAULT_MAX_MEM +setting to a reasonable value for your system (either by adding a #define for +DEFAULT_MAX_MEM to jconfig.h, or by adding a -D switch to the Makefile). +This value limits the amount of data space the program will attempt to +allocate. Code and static data space isn't counted, so the actual memory +needs for cjpeg or djpeg are typically 100 to 150Kb more than the max-memory +setting. Larger max-memory settings reduce the amount of I/O needed to +process a large image, but too large a value can result in "insufficient +memory" failures. On most Unix machines (and other systems with virtual +memory), just set DEFAULT_MAX_MEM to several million and forget it. At the +other end of the spectrum, for MS-DOS machines you probably can't go much +above 300K to 400K. (On MS-DOS the value refers to conventional memory only. +Extended/expanded memory is handled separately by jmemdos.c.) + + +BUILDING THE SOFTWARE +===================== + +Now you should be able to compile the software. Just say "make" (or +whatever's necessary to start the compilation). Have a cup of coffee. + +Here are some things that could go wrong: + +If your compiler complains about undefined structures, you should be able to +shut it up by putting "#define INCOMPLETE_TYPES_BROKEN" in jconfig.h. + +If you have trouble with missing system include files or inclusion of the +wrong ones, read jinclude.h. This shouldn't happen if you used configure +or ckconfig.c to set up jconfig.h. + +There are a fair number of routines that do not use all of their parameters; +some compilers will issue warnings about this, which you can ignore. There +are also a few configuration checks that may give "unreachable code" warnings. +Any other warning deserves investigation. + +If you don't have a getenv() library routine, define NO_GETENV. + +Also see the system-specific hints, below. + + +TESTING THE SOFTWARE +==================== + +As a quick test of functionality we've included a small sample image in +several forms: + testorig.jpg Starting point for the djpeg tests. + testimg.ppm The output of djpeg testorig.jpg + testimg.bmp The output of djpeg -bmp -colors 256 testorig.jpg + testimg.jpg The output of cjpeg testimg.ppm + testprog.jpg Progressive-mode equivalent of testorig.jpg. + testimgp.jpg The output of cjpeg -progressive -optimize testimg.ppm +(The first- and second-generation .jpg files aren't identical since the +default compression parameters are lossy.) If you can generate duplicates +of the testimg* files then you probably have working programs. + +With most of the makefiles, "make test" will perform the necessary +comparisons. + +If you're using a makefile that doesn't provide the test option, run djpeg +and cjpeg by hand and compare the output files to testimg* with whatever +binary file comparison tool you have. The files should be bit-for-bit +identical. + +If the programs complain "MAX_ALLOC_CHUNK is wrong, please fix", then you +need to reduce MAX_ALLOC_CHUNK to a value that fits in type size_t. +Try adding "#define MAX_ALLOC_CHUNK 65520L" to jconfig.h. A less likely +configuration error is "ALIGN_TYPE is wrong, please fix": defining ALIGN_TYPE +as long should take care of that one. + +If the cjpeg test run fails with "Missing Huffman code table entry", it's a +good bet that you needed to define RIGHT_SHIFT_IS_UNSIGNED. Go back to the +configuration step and run ckconfig.c. (This is a good plan for any other +test failure, too.) + +If you are using Unix (one-file) command line style on a non-Unix system, +it's a good idea to check that binary I/O through stdin/stdout actually +works. You should get the same results from "djpeg out.ppm" +as from "djpeg -outfile out.ppm testorig.jpg". Note that the makefiles all +use the latter style and therefore do not exercise stdin/stdout! If this +check fails, try recompiling with USE_SETMODE or USE_FDOPEN defined. +If it still doesn't work, better use two-file style. + +If you chose a memory manager other than jmemnobs.c, you should test that +temporary-file usage works. Try "djpeg -bmp -colors 256 -max 0 testorig.jpg" +and make sure its output matches testimg.bmp. If you have any really large +images handy, try compressing them with -optimize and/or decompressing with +-colors 256 to make sure your DEFAULT_MAX_MEM setting is not too large. + +NOTE: this is far from an exhaustive test of the JPEG software; some modules, +such as 1-pass color quantization, are not exercised at all. It's just a +quick test to give you some confidence that you haven't missed something +major. + + +INSTALLING THE SOFTWARE +======================= + +Once you're done with the above steps, you can install the software by +copying the executable files (cjpeg, djpeg, jpegtran, rdjpgcom, and wrjpgcom) +to wherever you normally install programs. On Unix systems, you'll also want +to put the man pages (cjpeg.1, djpeg.1, jpegtran.1, rdjpgcom.1, wrjpgcom.1) +in the man-page directory. The pre-fab makefiles don't support this step +since there's such a wide variety of installation procedures on different +systems. + +If you generated a Makefile with the "configure" script, you can just say + make install +to install the programs and their man pages into the standard places. +(You'll probably need to be root to do this.) We recommend first saying + make -n install +to see where configure thought the files should go. You may need to edit +the Makefile, particularly if your system's conventions for man page +filenames don't match what configure expects. + +If you want to install the IJG library itself, for use in compiling other +programs besides ours, then you need to put the four include files + jpeglib.h jerror.h jconfig.h jmorecfg.h +into your include-file directory, and put the library file libjpeg.a +(extension may vary depending on system) wherever library files go. +If you generated a Makefile with "configure", it will do what it thinks +is the right thing if you say + make install-lib + + +OPTIONAL STUFF +============== + +Progress monitor: + +If you like, you can #define PROGRESS_REPORT (in jconfig.h) to enable display +of percent-done progress reports. The routine provided in cdjpeg.c merely +prints percentages to stderr, but you can customize it to do something +fancier. + +Utah RLE file format support: + +We distribute the software with support for RLE image files (Utah Raster +Toolkit format) disabled, because the RLE support won't compile without the +Utah library. If you have URT version 3.1 or later, you can enable RLE +support as follows: + 1. #define RLE_SUPPORTED in jconfig.h. + 2. Add a -I option to CFLAGS in the Makefile for the directory + containing the URT .h files (typically the "include" + subdirectory of the URT distribution). + 3. Add -L... -lrle to LDLIBS in the Makefile, where ... specifies + the directory containing the URT "librle.a" file (typically the + "lib" subdirectory of the URT distribution). + +Support for 9-bit to 12-bit deep pixel data: + +The IJG code currently allows 8, 9, 10, 11, or 12 bits sample data precision. +(For color, this means 8 to 12 bits per channel, of course.) If you need to +work with deeper than 8-bit data, you can compile the IJG code for 9-bit to +12-bit operation. +To do so: + 1. In jmorecfg.h, define BITS_IN_JSAMPLE as 9, 10, 11, or 12 rather than 8. + 2. In jconfig.h, undefine BMP_SUPPORTED, RLE_SUPPORTED, and TARGA_SUPPORTED, + because the code for those formats doesn't handle deeper than 8-bit data + and won't even compile. (The PPM code does work, as explained below. + The GIF code works too; it scales 8-bit GIF data to and from 12-bit + depth automatically.) + 3. Compile. Don't expect "make test" to pass, since the supplied test + files are for 8-bit data. + +Currently, 9-bit to 12-bit support does not work on 16-bit-int machines. + +Run-time selection and conversion of data precision are currently not +supported and may be added later. +Exception: The transcoding part (jpegtran) supports all settings in a +single instance, since it operates on the level of DCT coefficients and +not sample values. + +The PPM reader (rdppm.c) can read deeper than 8-bit data from either +text-format or binary-format PPM and PGM files. Binary-format PPM/PGM files +which have a maxval greater than 255 are assumed to use 2 bytes per sample, +MSB first (big-endian order). As of early 1995, 2-byte binary format is not +officially supported by the PBMPLUS library, but it is expected that a +future release of PBMPLUS will support it. Note that the PPM reader will +read files of any maxval regardless of the BITS_IN_JSAMPLE setting; incoming +data is automatically rescaled to maxval=MAXJSAMPLE as appropriate for the +cjpeg bit depth. + +The PPM writer (wrppm.c) will normally write 2-byte binary PPM or PGM +format, maxval=MAXJSAMPLE, when compiled with BITS_IN_JSAMPLE>8. Since this +format is not yet widely supported, you can disable it by compiling wrppm.c +with PPM_NORAWWORD defined; then the data is scaled down to 8 bits to make a +standard 1-byte/sample PPM or PGM file. (Yes, this means still another copy +of djpeg to keep around. But hopefully you won't need it for very long. +Poskanzer's supposed to get that new PBMPLUS release out Real Soon Now.) + +Of course, if you are working with 9-bit to 12-bit data, you probably have +it stored in some other, nonstandard format. In that case you'll probably +want to write your own I/O modules to read and write your format. + +Note: +The standard Huffman tables are only valid for 8-bit data precision. If +you selected more than 8-bit data precision, cjpeg uses arithmetic coding +by default. The Huffman encoder normally uses entropy optimization to +compute usable tables for higher precision. Otherwise, you'll have to +supply different default Huffman tables. + +Removing code: + +If you need to make a smaller version of the JPEG software, some optional +functions can be removed at compile time. See the xxx_SUPPORTED #defines in +jconfig.h and jmorecfg.h. If at all possible, we recommend that you leave in +decoder support for all valid JPEG files, to ensure that you can read anyone's +output. Taking out support for image file formats that you don't use is the +most painless way to make the programs smaller. Another possibility is to +remove some of the DCT methods: in particular, the "IFAST" method may not be +enough faster than the others to be worth keeping on your machine. (If you +do remove ISLOW or IFAST, be sure to redefine JDCT_DEFAULT or JDCT_FASTEST +to a supported method, by adding a #define in jconfig.h.) + + +OPTIMIZATION +============ + +Unless you own a Cray, you'll probably be interested in making the JPEG +software go as fast as possible. This section covers some machine-dependent +optimizations you may want to try. We suggest that before trying any of +this, you first get the basic installation to pass the self-test step. +Repeat the self-test after any optimization to make sure that you haven't +broken anything. + +The integer DCT routines perform a lot of multiplications. These +multiplications must yield 32-bit results, but none of their input values +are more than 16 bits wide. On many machines, notably the 680x0 and 80x86 +CPUs, a 16x16=>32 bit multiply instruction is faster than a full 32x32=>32 +bit multiply. Unfortunately there is no portable way to specify such a +multiplication in C, but some compilers can generate one when you use the +right combination of casts. See the MULTIPLYxxx macro definitions in +jdct.h. If your compiler makes "int" be 32 bits and "short" be 16 bits, +defining SHORTxSHORT_32 is fairly likely to work. When experimenting with +alternate definitions, be sure to test not only whether the code still works +(use the self-test), but also whether it is actually faster --- on some +compilers, alternate definitions may compute the right answer, yet be slower +than the default. Timing cjpeg on a large PGM (grayscale) input file is the +best way to check this, as the DCT will be the largest fraction of the runtime +in that mode. (Note: some of the distributed compiler-specific jconfig files +already contain #define switches to select appropriate MULTIPLYxxx +definitions.) + +If your machine has sufficiently fast floating point hardware, you may find +that the float DCT method is faster than the integer DCT methods, even +after tweaking the integer multiply macros. In that case you may want to +make the float DCT be the default method. (The only objection to this is +that float DCT results may vary slightly across machines.) To do that, add +"#define JDCT_DEFAULT JDCT_FLOAT" to jconfig.h. Even if you don't change +the default, you should redefine JDCT_FASTEST, which is the method selected +by djpeg's -fast switch. Don't forget to update the documentation files +(usage.txt and/or cjpeg.1, djpeg.1) to agree with what you've done. + +If access to "short" arrays is slow on your machine, it may be a win to +define type JCOEF as int rather than short. This will cost a good deal of +memory though, particularly in some multi-pass modes, so don't do it unless +you have memory to burn and short is REALLY slow. + +If your compiler can compile function calls in-line, make sure the INLINE +macro in jmorecfg.h is defined as the keyword that marks a function +inline-able. Some compilers have a switch that tells the compiler to inline +any function it thinks is profitable (e.g., -finline-functions for gcc). +Enabling such a switch is likely to make the compiled code bigger but faster. + +In general, it's worth trying the maximum optimization level of your compiler, +and experimenting with any optional optimizations such as loop unrolling. +(Unfortunately, far too many compilers have optimizer bugs ... be prepared to +back off if the code fails self-test.) If you do any experimentation along +these lines, please report the optimal settings to jpeg-info@jpegclub.org so +we can mention them in future releases. Be sure to specify your machine and +compiler version. + + +HINTS FOR SPECIFIC SYSTEMS +========================== + +We welcome reports on changes needed for systems not mentioned here. Submit +'em to jpeg-info@jpegclub.org. Also, if configure or ckconfig.c is wrong +about how to configure the JPEG software for your system, please let us know. + + +Acorn RISC OS: + +(Thanks to Simon Middleton for these hints on compiling with Desktop C.) +After renaming the files according to Acorn conventions, take a copy of +makefile.ansi, change all occurrences of 'libjpeg.a' to 'libjpeg.o' and +change these definitions as indicated: + +CFLAGS= -throwback -IC: -Wn +LDLIBS=C:o.Stubs +SYSDEPMEM=jmemansi.o +LN=Link +AR=LibFile -c -o + +Also add a new line '.c.o:; $(cc) $< $(cflags) -c -o $@'. Remove the +lines '$(RM) libjpeg.o' and '$(AR2) libjpeg.o' and the 'jconfig.h' +dependency section. + +Copy jconfig.txt to jconfig.h. Edit jconfig.h to define TWO_FILE_COMMANDLINE +and CHAR_IS_UNSIGNED. + +Run the makefile using !AMU not !Make. If you want to use the 'clean' and +'test' makefile entries then you will have to fiddle with the syntax a bit +and rename the test files. + + +Amiga: + +SAS C 6.50 reportedly is too buggy to compile the IJG code properly. +A patch to update to 6.51 is available from SAS or AmiNet FTP sites. + +The supplied config files are set up to use jmemname.c as the memory +manager, with temporary files being created on the device named by +"JPEGTMP:". + + +Atari ST/STE/TT: + +Copy the project files makcjpeg.st, makdjpeg.st, maktjpeg.st, and makljpeg.st +to cjpeg.prj, djpeg.prj, jpegtran.prj, and libjpeg.prj respectively. The +project files should work as-is with Pure C. For Turbo C, change library +filenames "pc..." to "tc..." in each project file. Note that libjpeg.prj +selects jmemansi.c as the recommended memory manager. You'll probably want to +adjust the DEFAULT_MAX_MEM setting --- you want it to be a couple hundred K +less than your normal free memory. Put "#define DEFAULT_MAX_MEM nnnn" into +jconfig.h to do this. + +To use the 68881/68882 coprocessor for the floating point DCT, add the +compiler option "-8" to the project files and replace pcfltlib.lib with +pc881lib.lib in cjpeg.prj and djpeg.prj. Or if you don't have a +coprocessor, you may prefer to remove the float DCT code by undefining +DCT_FLOAT_SUPPORTED in jmorecfg.h (since without a coprocessor, the float +code will be too slow to be useful). In that case, you can delete +pcfltlib.lib from the project files. + +Note that you must make libjpeg.lib before making cjpeg.ttp, djpeg.ttp, +or jpegtran.ttp. You'll have to perform the self-test by hand. + +We haven't bothered to include project files for rdjpgcom and wrjpgcom. +Those source files should just be compiled by themselves; they don't +depend on the JPEG library. You can use the default.prj project file +of the Pure C distribution to make the programs. + +There is a bug in some older versions of the Turbo C library which causes the +space used by temporary files created with "tmpfile()" not to be freed after +an abnormal program exit. If you check your disk afterwards, you will find +cluster chains that are allocated but not used by a file. This should not +happen in cjpeg/djpeg/jpegtran, since we enable a signal catcher to explicitly +close temp files before exiting. But if you use the JPEG library with your +own code, be sure to supply a signal catcher, or else use a different +system-dependent memory manager. + + +Cray: + +Should you be so fortunate as to be running JPEG on a Cray YMP, there is a +compiler bug in old versions of Cray's Standard C (prior to 3.1). If you +still have an old compiler, you'll need to insert a line reading +"#pragma novector" just before the loop + for (i = 1; i <= (int) htbl->bits[l]; i++) + huffsize[p++] = (char) l; +in fix_huff_tbl (in V5beta1, line 204 of jchuff.c and line 176 of jdhuff.c). +[This bug may or may not still occur with the current IJG code, but it's +probably a dead issue anyway...] + + +HP-UX: + +If you have HP-UX 7.05 or later with the "software development" C compiler, +you should run the compiler in ANSI mode. If using the configure script, +say + ./configure CC='cc -Aa' +(or -Ae if you prefer). If configuring by hand, use makefile.ansi and add +"-Aa" to the CFLAGS line in the makefile. + +If you have a pre-7.05 system, or if you are using the non-ANSI C compiler +delivered with a minimum HP-UX system, then you must use makefile.unix +(and do NOT add -Aa); or just run configure without the CC option. + +On HP 9000 series 800 machines, the HP C compiler is buggy in revisions prior +to A.08.07. If you get complaints about "not a typedef name", you'll have to +use makefile.unix, or run configure without the CC option. + + +Macintosh, generic comments: + +The supplied user-interface files (cjpeg.c, djpeg.c, etc) are set up to +provide a Unix-style command line interface. You can use this interface on +the Mac by means of the ccommand() library routine provided by Metrowerks +CodeWarrior or Think C. This is only appropriate for testing the library, +however; to make a user-friendly equivalent of cjpeg/djpeg you'd really want +to develop a Mac-style user interface. There isn't a complete example +available at the moment, but there are some helpful starting points: +1. Sam Bushell's free "To JPEG" applet provides drag-and-drop conversion to +JPEG under System 7 and later. This only illustrates how to use the +compression half of the library, but it does a very nice job of that part. +The CodeWarrior source code is available from http://www.pobox.com/~jsam. +2. Jim Brunner prepared a Mac-style user interface for both compression and +decompression. Unfortunately, it hasn't been updated since IJG v4, and +the library's API has changed considerably since then. Still it may be of +some help, particularly as a guide to compiling the IJG code under Think C. +Jim's code is available from the Info-Mac archives, at sumex-aim.stanford.edu +or mirrors thereof; see file /info-mac/dev/src/jpeg-convert-c.hqx. + +jmemmac.c is the recommended memory manager back end for Macintosh. It uses +NewPtr/DisposePtr instead of malloc/free, and has a Mac-specific +implementation of jpeg_mem_available(). It also creates temporary files that +follow Mac conventions. (That part of the code relies on System-7-or-later OS +functions. See the comments in jmemmac.c if you need to run it on System 6.) +NOTE that USE_MAC_MEMMGR must be defined in jconfig.h to use jmemmac.c. + +You can also use jmemnobs.c, if you don't care about handling images larger +than available memory. If you use any memory manager back end other than +jmemmac.c, we recommend replacing "malloc" and "free" by "NewPtr" and +"DisposePtr", because Mac C libraries often have peculiar implementations of +malloc/free. (For instance, free() may not return the freed space to the +Mac Memory Manager. This is undesirable for the IJG code because jmemmgr.c +already clumps space requests.) + + +Macintosh, Metrowerks CodeWarrior: + +The Unix-command-line-style interface can be used by defining USE_CCOMMAND. +You'll also need to define TWO_FILE_COMMANDLINE to avoid stdin/stdout. +This means that when using the cjpeg/djpeg programs, you'll have to type the +input and output file names in the "Arguments" text-edit box, rather than +using the file radio buttons. (Perhaps USE_FDOPEN or USE_SETMODE would +eliminate the problem, but I haven't heard from anyone who's tried it.) + +On 680x0 Macs, Metrowerks defines type "double" as a 10-byte IEEE extended +float. jmemmgr.c won't like this: it wants sizeof(ALIGN_TYPE) to be a power +of 2. Add "#define ALIGN_TYPE long" to jconfig.h to eliminate the complaint. + +The supplied configuration file jconfig.mac can be used for your jconfig.h; +it includes all the recommended symbol definitions. If you have AppleScript +installed, you can run the supplied script makeproj.mac to create CodeWarrior +project files for the library and the testbed applications, then build the +library and applications. (Thanks to Dan Sears and Don Agro for this nifty +hack, which saves us from trying to maintain CodeWarrior project files as part +of the IJG distribution...) + + +Macintosh, Think C: + +The documentation in Jim Brunner's "JPEG Convert" source code (see above) +includes detailed build instructions for Think C; it's probably somewhat +out of date for the current release, but may be helpful. + +If you want to build the minimal command line version, proceed as follows. +You'll have to prepare project files for the programs; we don't include any +in the distribution since they are not text files. Use the file lists in +any of the supplied makefiles as a guide. Also add the ANSI and Unix C +libraries in a separate segment. You may need to divide the JPEG files into +more than one segment; we recommend dividing compression and decompression +modules. Define USE_CCOMMAND in jconfig.h so that the ccommand() routine is +called. You must also define TWO_FILE_COMMANDLINE because stdin/stdout +don't handle binary data correctly. + +On 680x0 Macs, Think C defines type "double" as a 12-byte IEEE extended float. +jmemmgr.c won't like this: it wants sizeof(ALIGN_TYPE) to be a power of 2. +Add "#define ALIGN_TYPE long" to jconfig.h to eliminate the complaint. + +jconfig.mac should work as a jconfig.h configuration file for Think C, +but the makeproj.mac AppleScript script is specific to CodeWarrior. Sorry. + + +MIPS R3000: + +MIPS's cc version 1.31 has a rather nasty optimization bug. Don't use -O +if you have that compiler version. (Use "cc -V" to check the version.) +Note that the R3000 chip is found in workstations from DEC and others. + + +MS-DOS, generic comments for 16-bit compilers: + +The IJG code is designed to work well in 80x86 "small" or "medium" memory +models (i.e., data pointers are 16 bits unless explicitly declared "far"; +code pointers can be either size). You may be able to use small model to +compile cjpeg or djpeg by itself, but you will probably have to use medium +model for any larger application. This won't make much difference in +performance. You *will* take a noticeable performance hit if you use a +large-data memory model, and you should avoid "huge" model if at all +possible. Be sure that NEED_FAR_POINTERS is defined in jconfig.h if you use +a small-data memory model; be sure it is NOT defined if you use a large-data +model. (The supplied makefiles and jconfig files for Borland and Microsoft C +compile in medium model and define NEED_FAR_POINTERS.) + +The DOS-specific memory manager, jmemdos.c, should be used if possible. +It needs some assembly-code routines which are in jmemdosa.asm; make sure +your makefile assembles that file and includes it in the library. If you +don't have a suitable assembler, you can get pre-assembled object files for +jmemdosa by FTP from ftp.uu.net:/graphics/jpeg/jdosaobj.zip. (DOS-oriented +distributions of the IJG source code often include these object files.) + +When using jmemdos.c, jconfig.h must define USE_MSDOS_MEMMGR and must set +MAX_ALLOC_CHUNK to less than 64K (65520L is a typical value). If your +C library's far-heap malloc() can't allocate blocks that large, reduce +MAX_ALLOC_CHUNK to whatever it can handle. + +If you can't use jmemdos.c for some reason --- for example, because you +don't have an assembler to assemble jmemdosa.asm --- you'll have to fall +back to jmemansi.c or jmemname.c. You'll probably still need to set +MAX_ALLOC_CHUNK in jconfig.h, because most DOS C libraries won't malloc() +more than 64K at a time. IMPORTANT: if you use jmemansi.c or jmemname.c, +you will have to compile in a large-data memory model in order to get the +right stdio library. Too bad. + +wrjpgcom needs to be compiled in large model, because it malloc()s a 64KB +work area to hold the comment text. If your C library's malloc can't +handle that, reduce MAX_COM_LENGTH as necessary in wrjpgcom.c. + +Most MS-DOS compilers treat stdin/stdout as text files, so you must use +two-file command line style. But if your compiler has either fdopen() or +setmode(), you can use one-file style if you like. To do this, define +USE_SETMODE or USE_FDOPEN so that stdin/stdout will be set to binary mode. +(USE_SETMODE seems to work with more DOS compilers than USE_FDOPEN.) You +should test that I/O through stdin/stdout produces the same results as I/O +to explicitly named files... the "make test" procedures in the supplied +makefiles do NOT use stdin/stdout. + + +MS-DOS, generic comments for 32-bit compilers: + +None of the above comments about memory models apply if you are using a +32-bit flat-memory-space environment, such as DJGPP or Watcom C. (And you +should use one if you have it, as performance will be much better than +8086-compatible code!) For flat-memory-space compilers, do NOT define +NEED_FAR_POINTERS, and do NOT use jmemdos.c. Use jmemnobs.c if the +environment supplies adequate virtual memory, otherwise use jmemansi.c or +jmemname.c. + +You'll still need to be careful about binary I/O through stdin/stdout. +See the last paragraph of the previous section. + + +MS-DOS, Borland C: + +Be sure to convert all the source files to DOS text format (CR/LF newlines). +Although Borland C will often work OK with unmodified Unix (LF newlines) +source files, sometimes it will give bogus compile errors. +"Illegal character '#'" is the most common such error. (This is true with +Borland C 3.1, but perhaps is fixed in newer releases.) + +If you want one-file command line style, just undefine TWO_FILE_COMMANDLINE. +jconfig.bcc already includes #define USE_SETMODE to make this work. +(fdopen does not work correctly.) + + +MS-DOS, Microsoft C: + +makefile.mc6 works with Microsoft C, DOS Visual C++, etc. It should only +be used if you want to build a 16-bit (small or medium memory model) program. + +If you want one-file command line style, just undefine TWO_FILE_COMMANDLINE. +jconfig.mc6 already includes #define USE_SETMODE to make this work. +(fdopen does not work correctly.) + +Note that this makefile assumes that the working copy of itself is called +"makefile". If you want to call it something else, say "makefile.mak", +be sure to adjust the dependency line that reads "$(RFILE) : makefile". +Otherwise the make will fail because it doesn't know how to create "makefile". +Worse, some releases of Microsoft's make utilities give an incorrect error +message in this situation. + +Old versions of MS C fail with an "out of macro expansion space" error +because they can't cope with the macro TRACEMS8 (defined in jerror.h). +If this happens to you, the easiest solution is to change TRACEMS8 to +expand to nothing. You'll lose the ability to dump out JPEG coefficient +tables with djpeg -debug -debug, but at least you can compile. + +Original MS C 6.0 is very buggy; it compiles incorrect code unless you turn +off optimization entirely (remove -O from CFLAGS). 6.00A is better, but it +still generates bad code if you enable loop optimizations (-Ol or -Ox). + +MS C 8.0 crashes when compiling jquant1.c with optimization switch /Oo ... +which is on by default. To work around this bug, compile that one file +with /Oo-. + + +Microsoft Windows (all versions), generic comments: + +Some Windows system include files define typedef boolean as "unsigned char". +The IJG code also defines typedef boolean, but we make it an "enum" by default. +This doesn't affect the IJG programs because we don't import those Windows +include files. But if you use the JPEG library in your own program, and some +of your program's files import one definition of boolean while some import the +other, you can get all sorts of mysterious problems. A good preventive step +is to make the IJG library use "unsigned char" for boolean. To do that, +add something like this to your jconfig.h file: + /* Define "boolean" as unsigned char, not enum, per Windows custom */ + #ifndef __RPCNDR_H__ /* don't conflict if rpcndr.h already read */ + typedef unsigned char boolean; + #endif + #ifndef FALSE /* in case these macros already exist */ + #define FALSE 0 /* values of boolean */ + #endif + #ifndef TRUE + #define TRUE 1 + #endif + #define HAVE_BOOLEAN /* prevent jmorecfg.h from redefining it */ +(This is already in jconfig.vc, by the way.) + +windef.h contains the declarations + #define far + #define FAR far +Since jmorecfg.h tries to define FAR as empty, you may get a compiler +warning if you include both jpeglib.h and windef.h (which windows.h +includes). To suppress the warning, you can put "#ifndef FAR"/"#endif" +around the line "#define FAR" in jmorecfg.h. +(Something like this is already in jmorecfg.h, by the way.) + +When using the library in a Windows application, you will almost certainly +want to modify or replace the error handler module jerror.c, since our +default error handler does a couple of inappropriate things: + 1. it tries to write error and warning messages on stderr; + 2. in event of a fatal error, it exits by calling exit(). + +A simple stopgap solution for problem 1 is to replace the line + fprintf(stderr, "%s\n", buffer); +(in output_message in jerror.c) with + MessageBox(GetActiveWindow(),buffer,"JPEG Error",MB_OK|MB_ICONERROR); +It's highly recommended that you at least do that much, since otherwise +error messages will disappear into nowhere. (Beginning with IJG v6b, this +code is already present in jerror.c; just define USE_WINDOWS_MESSAGEBOX in +jconfig.h to enable it.) + +The proper solution for problem 2 is to return control to your calling +application after a library error. This can be done with the setjmp/longjmp +technique discussed in libjpeg.txt and illustrated in example.c. (NOTE: +some older Windows C compilers provide versions of setjmp/longjmp that +don't actually work under Windows. You may need to use the Windows system +functions Catch and Throw instead.) + +The recommended memory manager under Windows is jmemnobs.c; in other words, +let Windows do any virtual memory management needed. You should NOT use +jmemdos.c nor jmemdosa.asm under Windows. + +For Windows 3.1, we recommend compiling in medium or large memory model; +for newer Windows versions, use a 32-bit flat memory model. (See the MS-DOS +sections above for more info about memory models.) In the 16-bit memory +models only, you'll need to put + #define MAX_ALLOC_CHUNK 65520L /* Maximum request to malloc() */ +into jconfig.h to limit allocation chunks to 64Kb. (Without that, you'd +have to use huge memory model, which slows things down unnecessarily.) +jmemnobs.c works without modification in large or flat memory models, but to +use medium model, you need to modify its jpeg_get_large and jpeg_free_large +routines to allocate far memory. In any case, you might like to replace +its calls to malloc and free with direct calls on Windows memory allocation +functions. + +You may also want to modify jdatasrc.c and jdatadst.c to use Windows file +operations rather than fread/fwrite. This is only necessary if your C +compiler doesn't provide a competent implementation of C stdio functions. + +You might want to tweak the RGB_xxx macros in jmorecfg.h so that the library +will accept or deliver color pixels in BGR sample order, not RGB; BGR order +is usually more convenient under Windows. Note that this change will break +the sample applications cjpeg/djpeg, but the library itself works fine. + + +Many people want to convert the IJG library into a DLL. This is reasonably +straightforward, but watch out for the following: + + 1. Don't try to compile as a DLL in small or medium memory model; use +large model, or even better, 32-bit flat model. Many places in the IJG code +assume the address of a local variable is an ordinary (not FAR) pointer; +that isn't true in a medium-model DLL. + + 2. Microsoft C cannot pass file pointers between applications and DLLs. +(See Microsoft Knowledge Base, PSS ID Number Q50336.) So jdatasrc.c and +jdatadst.c don't work if you open a file in your application and then pass +the pointer to the DLL. One workaround is to make jdatasrc.c/jdatadst.c +part of your main application rather than part of the DLL. + + 3. You'll probably need to modify the macros GLOBAL() and EXTERN() to +attach suitable linkage keywords to the exported routine names. Similarly, +you'll want to modify METHODDEF() and JMETHOD() to ensure function pointers +are declared in a way that lets application routines be called back through +the function pointers. These macros are in jmorecfg.h. Typical definitions +for a 16-bit DLL are: + #define GLOBAL(type) type _far _pascal _loadds _export + #define EXTERN(type) extern type _far _pascal _loadds + #define METHODDEF(type) static type _far _pascal + #define JMETHOD(type,methodname,arglist) \ + type (_far _pascal *methodname) arglist +For a 32-bit DLL you may want something like + #define GLOBAL(type) __declspec(dllexport) type + #define EXTERN(type) extern __declspec(dllexport) type +Although not all the GLOBAL routines are actually intended to be called by +the application, the performance cost of making them all DLL entry points is +negligible. + +The unmodified IJG library presents a very C-specific application interface, +so the resulting DLL is only usable from C or C++ applications. There has +been some talk of writing wrapper code that would present a simpler interface +usable from other languages, such as Visual Basic. This is on our to-do list +but hasn't been very high priority --- any volunteers out there? + + +Microsoft Windows, Borland C: + +The provided jconfig.bcc should work OK in a 32-bit Windows environment, +but you'll need to tweak it in a 16-bit environment (you'd need to define +NEED_FAR_POINTERS and MAX_ALLOC_CHUNK). Beware that makefile.bcc will need +alteration if you want to use it for Windows --- in particular, you should +use jmemnobs.c not jmemdos.c under Windows. + +Borland C++ 4.5 fails with an internal compiler error when trying to compile +jdmerge.c in 32-bit mode. If enough people complain, perhaps Borland will fix +it. In the meantime, the simplest known workaround is to add a redundant +definition of the variable range_limit in h2v1_merged_upsample(), at the head +of the block that handles odd image width (about line 268 in v6 jdmerge.c): + /* If image width is odd, do the last output column separately */ + if (cinfo->output_width & 1) { + register JSAMPLE * range_limit = cinfo->sample_range_limit; /* ADD THIS */ + cb = GETJSAMPLE(*inptr1); +Pretty bizarre, especially since the very similar routine h2v2_merged_upsample +doesn't trigger the bug. +Recent reports suggest that this bug does not occur with "bcc32a" (the +Pentium-optimized version of the compiler). + +Another report from a user of Borland C 4.5 was that incorrect code (leading +to a color shift in processed images) was produced if any of the following +optimization switch combinations were used: + -Ot -Og + -Ot -Op + -Ot -Om +So try backing off on optimization if you see such a problem. (Are there +several different releases all numbered "4.5"??) + + +Microsoft Windows, Microsoft Visual C++: + +jconfig.vc should work OK with any Microsoft compiler for a 32-bit memory +model. makefile.vc is intended for command-line use. (If you are using +the Developer Studio environment, you may prefer the DevStudio project +files; see below.) + +IJG JPEG 7 adds extern "C" to jpeglib.h. This avoids the need to put +extern "C" { ... } around #include "jpeglib.h" in your C++ application. +You can also force VC++ to treat the library as C++ code by renaming +all the *.c files to *.cpp (and adjusting the makefile to match). +In this case you also need to define the symbol DONT_USE_EXTERN_C in +the configuration to prevent jpeglib.h from using extern "C". + + +Microsoft Windows, Microsoft Visual C++ 6 Developer Studio: + +We include makefiles that should work as project files in DevStudio 6.0 or +later. There is a library makefile that builds the IJG library as a static +Win32 library, and application makefiles that build the sample applications +as Win32 console applications. (Even if you only want the library, we +recommend building the applications so that you can run the self-test.) + +To use: +1. Open the command prompt, change to the main directory and execute the + command line + NMAKE /f makefile.vc setup-vc6 + This will move jconfig.vc to jconfig.h and makefiles to project files. + (Note that the renaming is critical!) +2. Open the workspace file jpeg.dsw, build the library project. + (If you are using DevStudio more recent than 6.0, you'll probably + get a message saying that the project files are being updated.) +3. Open the workspace file apps.dsw, build the application projects. +4. To perform the self-test, execute the command line + NMAKE /f makefile.vc test-build +5. Move the application .exe files from `app`\Release to an + appropriate location on your path. + + +Microsoft Windows, Microsoft Visual C++ 2010 Developer Studio (v10): + +We include makefiles that should work as project files in Visual Studio +2010 or later. There is a library makefile that builds the IJG library +as a static Win32 library, and application makefiles that build the sample +applications as Win32 console applications. (Even if you only want the +library, we recommend building the applications so that you can run the +self-test.) + +To use: +1. Open the command prompt, change to the main directory and execute the + command line + NMAKE /f makefile.vc setup-v10 + This will move jconfig.vc to jconfig.h and makefiles to project files. + (Note that the renaming is critical!) +2. Open the solution file jpeg.sln, build the library project. + (If you are using Visual Studio more recent than 2010 (v10), you'll + probably get a message saying that the project files are being updated.) +3. Open the solution file apps.sln, build the application projects. +4. To perform the self-test, execute the command line + NMAKE /f makefile.vc test-build +5. Move the application .exe files from `app`\Release to an + appropriate location on your path. + +Note: +There seems to be an optimization bug in the compiler which causes the +self-test to fail with the color quantization option. +We have disabled optimization for the file jquant2.c in the library +project file which causes the self-test to pass properly. + + +OS/2, Borland C++: + +Watch out for optimization bugs in older Borland compilers; you may need +to back off the optimization switch settings. See the comments in +makefile.bcc. + + +SGI: + +On some SGI systems, you may need to set "AR2= ar -ts" in the Makefile. +If you are using configure, you can do this by saying + ./configure RANLIB='ar -ts' +This change is not needed on all SGIs. Use it only if the make fails at the +stage of linking the completed programs. + +On the MIPS R4000 architecture (Indy, etc.), the compiler option "-mips2" +reportedly speeds up the float DCT method substantially, enough to make it +faster than the default int method (but still slower than the fast int +method). If you use -mips2, you may want to alter the default DCT method to +be float. To do this, put "#define JDCT_DEFAULT JDCT_FLOAT" in jconfig.h. + + +VMS: + +On an Alpha/VMS system with MMS, be sure to use the "/Marco=Alpha=1" +qualifier with MMS when building the JPEG package. + +VAX/VMS v5.5-1 may have problems with the test step of the build procedure +reporting differences when it compares the original and test images. If the +error points to the last block of the files, it is most likely bogus and may +be safely ignored. It seems to be because the files are Stream_LF and +Backup/Compare has difficulty with the (presumably) null padded files. +This problem was not observed on VAX/VMS v6.1 or AXP/VMS v6.1. diff --git a/project/jni/sdl2_image/external/jpeg-9b/jaricom.c b/project/jni/sdl2_image/external/jpeg-9b/jaricom.c new file mode 100644 index 000000000..690068861 --- /dev/null +++ b/project/jni/sdl2_image/external/jpeg-9b/jaricom.c @@ -0,0 +1,153 @@ +/* + * jaricom.c + * + * Developed 1997-2011 by Guido Vollbeding. + * This file is part of the Independent JPEG Group's software. + * For conditions of distribution and use, see the accompanying README file. + * + * This file contains probability estimation tables for common use in + * arithmetic entropy encoding and decoding routines. + * + * This data represents Table D.3 in the JPEG spec (D.2 in the draft), + * ISO/IEC IS 10918-1 and CCITT Recommendation ITU-T T.81, and Table 24 + * in the JBIG spec, ISO/IEC IS 11544 and CCITT Recommendation ITU-T T.82. + */ + +#define JPEG_INTERNALS +#include "jinclude.h" +#include "jpeglib.h" + +/* The following #define specifies the packing of the four components + * into the compact INT32 representation. + * Note that this formula must match the actual arithmetic encoder + * and decoder implementation.

Nonetheless, the main controller is not + * trivial. Its responsibility is to provide context rows for upsampling/ + * rescaling, and doing this in an efficient fashion is a bit tricky. + * + * Postprocessor input data is counted in "row groups". A row group + * is defined to be (v_samp_factor * DCT_scaled_size / min_DCT_scaled_size) + * sample rows of each component. (We require DCT_scaled_size values to be + * chosen such that these numbers are integers. In practice DCT_scaled_size + * values will likely be powers of two, so we actually have the stronger + * condition that DCT_scaled_size / min_DCT_scaled_size is an integer.) + * Upsampling will typically produce max_v_samp_factor pixel rows from each + * row group (times any additional scale factor that the upsampler is + * applying). + * + * The coefficient controller will deliver data to us one iMCU row at a time; + * each iMCU row contains v_samp_factor * DCT_scaled_size sample rows, or + * exactly min_DCT_scaled_size row groups. (This amount of data corresponds + * to one row of MCUs when the image is fully interleaved.) Note that the + * number of sample rows varies across components, but the number of row + * groups does not. Some garbage sample rows may be included in the last iMCU + * row at the bottom of the image. + * + * Depending on the vertical scaling algorithm used, the upsampler may need + * access to the sample row(s) above and below its current input row group. + * The upsampler is required to set need_context_rows TRUE at global selection + * time if so. When need_context_rows is FALSE, this controller can simply + * obtain one iMCU row at a time from the coefficient controller and dole it + * out as row groups to the postprocessor. + * + * When need_context_rows is TRUE, this controller guarantees that the buffer + * passed to postprocessing contains at least one row group's worth of samples + * above and below the row group(s) being processed. Note that the context + * rows "above" the first passed row group appear at negative row offsets in + * the passed buffer. At the top and bottom of the image, the required + * context rows are manufactured by duplicating the first or last real sample + * row; this avoids having special cases in the upsampling inner loops. + * + * The amount of context is fixed at one row group just because that's a + * convenient number for this controller to work with. The existing + * upsamplers really only need one sample row of context. An upsampler + * supporting arbitrary output rescaling might wish for more than one row + * group of context when shrinking the image; tough, we don't handle that. + * (This is justified by the assumption that downsizing will be handled mostly + * by adjusting the DCT_scaled_size values, so that the actual scale factor at + * the upsample step needn't be much less than one.) + * + * To provide the desired context, we have to retain the last two row groups + * of one iMCU row while reading in the next iMCU row. (The last row group + * can't be processed until we have another row group for its below-context, + * and so we have to save the next-to-last group too for its above-context.) + * We could do this most simply by copying data around in our buffer, but + * that'd be very slow. We can avoid copying any data by creating a rather + * strange pointer structure. Here's how it works. We allocate a workspace + * consisting of M+2 row groups (where M = min_DCT_scaled_size is the number + * of row groups per iMCU row). We create two sets of redundant pointers to + * the workspace. Labeling the physical row groups 0 to M+1, the synthesized + * pointer lists look like this: + * M+1 M-1 + * master pointer --> 0 master pointer --> 0 + * 1 1 + * ... ... + * M-3 M-3 + * M-2 M + * M-1 M+1 + * M M-2 + * M+1 M-1 + * 0 0 + * We read alternate iMCU rows using each master pointer; thus the last two + * row groups of the previous iMCU row remain un-overwritten in the workspace. + * The pointer lists are set up so that the required context rows appear to + * be adjacent to the proper places when we pass the pointer lists to the + * upsampler. + * + * The above pictures describe the normal state of the pointer lists. + * At top and bottom of the image, we diddle the pointer lists to duplicate + * the first or last sample row as necessary (this is cheaper than copying + * sample rows around). + * + * This scheme breaks down if M < 2, ie, min_DCT_scaled_size is 1. In that + * situation each iMCU row provides only one row group so the buffering logic + * must be different (eg, we must read two iMCU rows before we can emit the + * first row group). For now, we simply do not support providing context + * rows when min_DCT_scaled_size is 1. That combination seems unlikely to + * be worth providing --- if someone wants a 1/8th-size preview, they probably + * want it quick and dirty, so a context-free upsampler is sufficient. + */ + + +/* Private buffer controller object */ + +typedef struct { + struct jpeg_d_main_controller pub; /* public fields */ + + /* Pointer to allocated workspace (M or M+2 row groups). */ + JSAMPARRAY buffer[MAX_COMPONENTS]; + + boolean buffer_full; /* Have we gotten an iMCU row from decoder? */ + JDIMENSION rowgroup_ctr; /* counts row groups output to postprocessor */ + + /* Remaining fields are only used in the context case. */ + + /* These are the master pointers to the funny-order pointer lists. */ + JSAMPIMAGE xbuffer[2]; /* pointers to weird pointer lists */ + + int whichptr; /* indicates which pointer set is now in use */ + int context_state; /* process_data state machine status */ + JDIMENSION rowgroups_avail; /* row groups available to postprocessor */ + JDIMENSION iMCU_row_ctr; /* counts iMCU rows to detect image top/bot */ +} my_main_controller; + +typedef my_main_controller * my_main_ptr; + +/* context_state values: */ +#define CTX_PREPARE_FOR_IMCU 0 /* need to prepare for MCU row */ +#define CTX_PROCESS_IMCU 1 /* feeding iMCU to postprocessor */ +#define CTX_POSTPONED_ROW 2 /* feeding postponed row group */ + + +/* Forward declarations */ +METHODDEF(void) process_data_simple_main + JPP((j_decompress_ptr cinfo, JSAMPARRAY output_buf, + JDIMENSION *out_row_ctr, JDIMENSION out_rows_avail)); +METHODDEF(void) process_data_context_main + JPP((j_decompress_ptr cinfo, JSAMPARRAY output_buf, + JDIMENSION *out_row_ctr, JDIMENSION out_rows_avail)); +#ifdef QUANT_2PASS_SUPPORTED +METHODDEF(void) process_data_crank_post + JPP((j_decompress_ptr cinfo, JSAMPARRAY output_buf, + JDIMENSION *out_row_ctr, JDIMENSION out_rows_avail)); +#endif + + +LOCAL(void) +alloc_funny_pointers (j_decompress_ptr cinfo) +/* Allocate space for the funny pointer lists. + * This is done only once, not once per pass. + */ +{ + my_main_ptr mainp = (my_main_ptr) cinfo->main; + int ci, rgroup; + int M = cinfo->min_DCT_v_scaled_size; + jpeg_component_info *compptr; + JSAMPARRAY xbuf; + + /* Get top-level space for component array pointers. + * We alloc both arrays with one call to save a few cycles. + */ + mainp->xbuffer[0] = (JSAMPIMAGE) + (*cinfo->mem->alloc_small) ((j_common_ptr) cinfo, JPOOL_IMAGE, + cinfo->num_components * 2 * SIZEOF(JSAMPARRAY)); + mainp->xbuffer[1] = mainp->xbuffer[0] + cinfo->num_components; + + for (ci = 0, compptr = cinfo->comp_info; ci < cinfo->num_components; + ci++, compptr++) { + rgroup = (compptr->v_samp_factor * compptr->DCT_v_scaled_size) / + cinfo->min_DCT_v_scaled_size; /* height of a row group of component */ + /* Get space for pointer lists --- M+4 row groups in each list. + * We alloc both pointer lists with one call to save a few cycles. + */ + xbuf = (JSAMPARRAY) + (*cinfo->mem->alloc_small) ((j_common_ptr) cinfo, JPOOL_IMAGE, + 2 * (rgroup * (M + 4)) * SIZEOF(JSAMPROW)); + xbuf += rgroup; /* want one row group at negative offsets */ + mainp->xbuffer[0][ci] = xbuf; + xbuf += rgroup * (M + 4); + mainp->xbuffer[1][ci] = xbuf; + } +} + + +LOCAL(void) +make_funny_pointers (j_decompress_ptr cinfo) +/* Create the funny pointer lists discussed in the comments above. + * The actual workspace is already allocated (in main->buffer), + * and the space for the pointer lists is allocated too. + * This routine just fills in the curiously ordered lists. + * This will be repeated at the beginning of each pass. + */ +{ + my_main_ptr mainp = (my_main_ptr) cinfo->main; + int ci, i, rgroup; + int M = cinfo->min_DCT_v_scaled_size; + jpeg_component_info *compptr; + JSAMPARRAY buf, xbuf0, xbuf1; + + for (ci = 0, compptr = cinfo->comp_info; ci < cinfo->num_components; + ci++, compptr++) { + rgroup = (compptr->v_samp_factor * compptr->DCT_v_scaled_size) / + cinfo->min_DCT_v_scaled_size; /* height of a row group of component */ + xbuf0 = mainp->xbuffer[0][ci]; + xbuf1 = mainp->xbuffer[1][ci]; + /* First copy the workspace pointers as-is */ + buf = mainp->buffer[ci]; + for (i = 0; i < rgroup * (M + 2); i++) { + xbuf0[i] = xbuf1[i] = buf[i]; + } + /* In the second list, put the last four row groups in swapped order */ + for (i = 0; i < rgroup * 2; i++) { + xbuf1[rgroup*(M-2) + i] = buf[rgroup*M + i]; + xbuf1[rgroup*M + i] = buf[rgroup*(M-2) + i]; + } + /* The wraparound pointers at top and bottom will be filled later + * (see set_wraparound_pointers, below).

Direct algorithms are also available, but they are much more + * complex and seem not to be any faster when reduced to code. + * + * This implementation is based on Arai, Agui, and Nakajima's algorithm for + * scaled DCT. Their original paper (Trans. IEICE E-71(11):1095) is in + * Japanese, but the algorithm is described in the Pennebaker & Mitchell + * JPEG textbook (see REFERENCES section in file README). The following code + * is based directly on figure 4-8 in P&M. + * While an 8-point DCT cannot be done in less than 11 multiplies, it is + * possible to arrange the computation so that many of the multiplies are + * simple scalings of the final outputs. These multiplies can then be + * folded into the multiplications or divisions by the JPEG quantization + * table entries. The AA&N method leaves only 5 multiplies and 29 adds + * to be done in the DCT itself. + * The primary disadvantage of this method is that with fixed-point math, + * accuracy is lost due to imprecise representation of the scaled + * quantization values.

The intended implementation is that there is a strip buffer in + * memory (as high as is possible given the desired memory limit), plus a + * backing file that holds the rest of the array. + * + * The request_virt_array routines are told the total size of the image and + * the maximum number of rows that will be accessed at once. The in-memory + * buffer must be at least as large as the maxaccess value. + * + * The request routines create control blocks but not the in-memory buffers. + * That is postponed until realize_virt_arrays is called. At that time the + * total amount of space needed is known (approximately, anyway), so free + * memory can be divided up fairly. + * + * The access_virt_array routines are responsible for making a specific strip + * area accessible (after reading or writing the backing file, if necessary). + * Note that the access routines are told whether the caller intends to modify + * the accessed strip; during a read-only pass this saves having to rewrite + * data to disk. The access routines are also responsible for pre-zeroing + * any newly accessed rows, if pre-zeroing was requested. + * + * In current usage, the access requests are usually for nonoverlapping + * strips; that is, successive access start_row numbers differ by exactly + * num_rows = maxaccess.

It can also +perform some rearrangements of the image data, for example turning an image +from landscape to portrait format by rotation. +.PP +For EXIF files and JPEG files containing Exif data, you may prefer to use +.B exiftran +instead. +.PP +.B jpegtran +works by rearranging the compressed data (DCT coefficients), without +ever fully decoding the image. Therefore, its transformations are lossless: +there is no image degradation at all, which would not be true if you used +.B djpeg +followed by +.B cjpeg +to accomplish the same conversion. But by the same token, +.B jpegtran +cannot perform lossy operations such as changing the image quality. However, +while the image data is losslessly transformed, metadata can be removed. See +the +.B \-copy +option for specifics. +.PP +.B jpegtran +reads the named JPEG/JFIF file, or the standard input if no file is +named, and produces a JPEG/JFIF file on the standard output. +.SH OPTIONS +All switch names may be abbreviated; for example, +.B \-optimize +may be written +.B \-opt +or +.BR \-o . +Upper and lower case are equivalent. +British spellings are also accepted (e.g., +.BR \-optimise ), +though for brevity these are not mentioned below. +.PP +To specify the coded JPEG representation used in the output file, +.B jpegtran +accepts a subset of the switches recognized by +.BR cjpeg : +.TP +.B \-optimize +Perform optimization of entropy encoding parameters. +.TP +.B \-progressive +Create progressive JPEG file. +.TP +.BI \-restart " N" +Emit a JPEG restart marker every N MCU rows, or every N MCU blocks if "B" is +attached to the number. +.TP +.B \-arithmetic +Use arithmetic coding. +.TP +.BI \-scans " file" +Use the scan script given in the specified text file. +.PP +See +.BR cjpeg (1) +for more details about these switches. +If you specify none of these switches, you get a plain baseline-JPEG output +file. The quality setting and so forth are determined by the input file. +.PP +The image can be losslessly transformed by giving one of these switches: +.TP +.B \-flip horizontal +Mirror image horizontally (left-right). +.TP +.B \-flip vertical +Mirror image vertically (top-bottom). +.TP +.B \-rotate 90 +Rotate image 90 degrees clockwise. +.TP +.B \-rotate 180 +Rotate image 180 degrees. +.TP +.B \-rotate 270 +Rotate image 270 degrees clockwise (or 90 ccw). +.TP +.B \-transpose +Transpose image (across UL-to-LR axis). +.TP +.B \-transverse +Transverse transpose (across UR-to-LL axis). +.IP +The transpose transformation has no restrictions regarding image dimensions. +The other transformations operate rather oddly if the image dimensions are not +a multiple of the iMCU size (usually 8 or 16 pixels), because they can only +transform complete blocks of DCT coefficient data in the desired way. +.IP +.BR jpegtran 's +default behavior when transforming an odd-size image is designed +to preserve exact reversibility and mathematical consistency of the +transformation set. As stated, transpose is able to flip the entire image +area. Horizontal mirroring leaves any partial iMCU column at the right edge +untouched, but is able to flip all rows of the image. Similarly, vertical +mirroring leaves any partial iMCU row at the bottom edge untouched, but is +able to flip all columns. The other transforms can be built up as sequences +of transpose and flip operations; for consistency, their actions on edge +pixels are defined to be the same as the end result of the corresponding +transpose-and-flip sequence. +.IP +For practical use, you may prefer to discard any untransformable edge pixels +rather than having a strange-looking strip along the right and/or bottom edges +of a transformed image. To do this, add the +.B \-trim +switch: +.TP +.B \-trim +Drop non-transformable edge blocks. +.IP +Obviously, a transformation with +.B \-trim +is not reversible, so strictly speaking +.B jpegtran +with this switch is not lossless. Also, the expected mathematical +equivalences between the transformations no longer hold. For example, +.B \-rot 270 -trim +trims only the bottom edge, but +.B \-rot 90 -trim +followed by +.B \-rot 180 -trim +trims both edges. +.IP +If you are only interested in perfect transformation, add the +.B \-perfect +switch: +.TP +.B \-perfect +Fails with an error if the transformation is not perfect. +.IP +For example you may want to do +.IP +.B (jpegtran \-rot 90 -perfect +.I foo.jpg +.B || djpeg +.I foo.jpg +.B | pnmflip \-r90 | cjpeg) +.IP +to do a perfect rotation if available or an approximated one if not. +.PP +We also offer a lossless-crop option, which discards data outside a given +image region but losslessly preserves what is inside. Like the rotate and +flip transforms, lossless crop is restricted by the current JPEG format: the +upper left corner of the selected region must fall on an iMCU boundary. If +this does not hold for the given crop parameters, we silently move the upper +left corner up and/or left to make it so, simultaneously increasing the +region dimensions to keep the lower right crop corner unchanged. (Thus, the +output image covers at least the requested region, but may cover more.) +The adjustment of the region dimensions may be optionally disabled by +attaching an 'f' character ("force") to the width or height number. + +The image can be losslessly cropped by giving the switch: +.TP +.B \-crop WxH+X+Y +Crop to a rectangular subarea of width W, height H starting at point X,Y. +.PP +A complementary lossless-wipe option is provided to discard (gray out) data +inside a given image region while losslessly preserving what is outside: +.TP +.B \-wipe WxH+X+Y +Wipe (gray out) a rectangular subarea of width W, height H starting at point +X,Y. +.PP +Other not-strictly-lossless transformation switches are: +.TP +.B \-grayscale +Force grayscale output. +.IP +This option discards the chrominance channels if the input image is YCbCr +(ie, a standard color JPEG), resulting in a grayscale JPEG file. The +luminance channel is preserved exactly, so this is a better method of reducing +to grayscale than decompression, conversion, and recompression. This switch +is particularly handy for fixing a monochrome picture that was mistakenly +encoded as a color JPEG. (In such a case, the space savings from getting rid +of the near-empty chroma channels won't be large; but the decoding time for +a grayscale JPEG is substantially less than that for a color JPEG.) +.TP +.BI \-scale " M/N" +Scale the output image by a factor M/N. +.IP +Currently supported scale factors are M/N with all M from 1 to 16, where N is +the source DCT size, which is 8 for baseline JPEG. If the /N part is omitted, +then M specifies the DCT scaled size to be applied on the given input. For +baseline JPEG this is equivalent to M/8 scaling, since the source DCT size +for baseline JPEG is 8. +.B Caution: +An implementation of the JPEG SmartScale extension is required for this +feature. SmartScale enabled JPEG is not yet widely implemented, so many +decoders will be unable to view a SmartScale extended JPEG file at all. +.PP +.B jpegtran +also recognizes these switches that control what to do with "extra" markers, +such as comment blocks: +.TP +.B \-copy none +Copy no extra markers from source file. This setting suppresses all +comments and other metadata in the source file. +.TP +.B \-copy comments +Copy only comment markers. This setting copies comments from the source file, +but discards any other metadata. +.TP +.B \-copy all +Copy all extra markers. This setting preserves metadata +found in the source file, such as JFIF thumbnails, Exif data, and Photoshop +settings. In some files these extra markers can be sizable. Note that this +option will copy thumbnails as-is; they will not be transformed. +.IP +The default behavior is +.BR "\-copy comments" . +(Note: in IJG releases v6 and v6a, +.B jpegtran +always did the equivalent of +.BR "\-copy none" .) +.PP +Additional switches recognized by jpegtran are: +.TP +.BI \-maxmemory " N" +Set limit for amount of memory to use in processing large images. Value is +in thousands of bytes, or millions of bytes if "M" is attached to the +number. For example, +.B \-max 4m +selects 4000000 bytes. If more space is needed, temporary files will be used. +.TP +.BI \-outfile " name" +Send output image to the named file, not to standard output. +.TP +.B \-verbose +Enable debug printout.

Dithering is highly recommended with this + * quantizer, though you can turn it off if you really want to. + * + * In 1-pass quantization the colormap must be chosen in advance of seeing the + * image. We use a map consisting of all combinations of Ncolors[i] color + * values for the i'th component. The Ncolors[] values are chosen so that + * their product, the total number of colors, is no more than that requested. + * (In most cases, the product will be somewhat less.) + * + * Since the colormap is orthogonal, the representative value for each color + * component can be determined without considering the other components; + * then these indexes can be combined into a colormap index by a standard + * N-dimensional-array-subscript calculation. Most of the arithmetic involved + * can be precalculated and stored in the lookup table colorindex[]. + * colorindex[i][j] maps pixel value j in component i to the nearest + * representative value (grid plane) for that component; this index is + * multiplied by the array stride for component i, so that the + * index of the colormap entry closest to a given pixel value is just + * sum( colorindex[component-number][pixel-component-value] ) + * Aside from being fast, this scheme allows for variable spacing between + * representative values with no additional lookup cost. + * + * If gamma correction has been applied in color conversion, it might be wise + * to adjust the color grid spacing so that the representative colors are + * equidistant in linear space.

To keep the histogram to a reasonable + * size, we reduce the precision of the input; typical practice is to retain + * 5 or 6 bits per color, so that 8 or 4 different input values are counted + * in the same histogram cell. + * + * Next, the color-selection step begins with a box representing the whole + * color space, and repeatedly splits the "largest" remaining box until we + * have as many boxes as desired colors. Then the mean color in each + * remaining box becomes one of the possible output colors. + * + * The second pass over the image maps each input pixel to the closest output + * color (optionally after applying a Floyd-Steinberg dithering correction). + * This mapping is logically trivial, but making it go fast enough requires + * considerable care. + * + * Heckbert-style quantizers vary a good deal in their policies for choosing + * the "largest" box and deciding where to cut it. The particular policies + * used here have proved out well in experimental comparisons, but better ones + * may yet be found. + * + * In earlier versions of the IJG code, this module quantized in YCbCr color + * space, processing the raw upsampled data without a color conversion step. + * This allowed the color conversion math to be done only once per colormap + * entry, not once per pixel. However, that optimization precluded other + * useful optimizations (such as merging color conversion with upsampling) + * and it also interfered with desired capabilities such as quantizing to an + * externally-supplied colormap. We have therefore abandoned that approach. + * The present code works in the post-conversion color space, typically RGB. + * + * To improve the visual quality of the results, we actually work in scaled + * RGB space, giving G distances more weight than R, and R in turn more than + * B. To do everything in integer math, we must use integer scale factors. + * The 2/3/1 scale factors used here correspond loosely to the relative + * weights of the colors in the NTSC grayscale equation. + * If you want to use this code to quantize a non-RGB color space, you'll + * probably need to change these scale factors. + */ + +#define R_SCALE 2 /* scale R distances by this much */ +#define G_SCALE 3 /* scale G distances by this much */ +#define B_SCALE 1 /* and B by this much */ + +/* Relabel R/G/B as components 0/1/2, respecting the RGB ordering defined + * in jmorecfg.h.

All colors within a + * histogram cell will be mapped to the same colormap entry, namely the one + * closest to the cell's center. This may not be quite the closest entry to + * the actual input color, but it's almost as good. A zero in the cache + * indicates we haven't found the nearest color for that cell yet; the array + * is cleared to zeroes before starting the mapping pass. When we find the + * nearest color for a cell, its colormap index plus one is recorded in the + * cache for future use. The pass2 scanning routines call fill_inverse_cmap + * when they need to use an unfilled entry in the cache. + * + * Our method of efficiently finding nearest colors is based on the "locally + * sorted search" idea described by Heckbert and on the incremental distance + * calculation described by Spencer W. Thomas in chapter III.1 of Graphics + * Gems II (James Arvo, ed. Academic Press, 1991). Thomas points out that + * the distances from a given colormap entry to each cell of the histogram can + * be computed quickly using an incremental method: the differences between + * distances to adjacent cells themselves differ by a constant. This allows a + * fairly fast implementation of the "brute force" approach of computing the + * distance from every colormap entry to every histogram cell. Unfortunately, + * it needs a work array to hold the best-distance-so-far for each histogram + * cell (because the inner loop has to be over cells, not colormap entries). + * The work array elements have to be INT32s, so the work array would need + * 256Kb at our recommended precision. This is not feasible in DOS machines. + * + * To get around these problems, we apply Thomas' method to compute the + * nearest colors for only the cells within a small subbox of the histogram. + * The work array need be only as big as the subbox, so the memory usage + * problem is solved. Furthermore, we need not fill subboxes that are never + * referenced in pass2; many images use only part of the color gamut, so a + * fair amount of work is saved. An additional advantage of this + * approach is that we can apply Heckbert's locality criterion to quickly + * eliminate colormap entries that are far away from the subbox; typically + * three-fourths of the colormap entries are rejected by Heckbert's criterion, + * and we need not compute their distances to individual cells in the subbox. + * The speed of this approach is heavily influenced by the subbox size: too + * small means too much overhead, too big loses because Heckbert's criterion + * can't eliminate as many colormap entries. Empirically the best subbox + * size seems to be about 1/512th of the histogram (1/8th in each direction). + * + * Thomas' article also describes a refined method which is asymptotically + * faster than the brute-force method, but it is also far more complex and + * cannot efficiently be applied to small subboxes.

The sections on advanced features can be read +if and when you need them. + + +OVERVIEW +======== + +Functions provided by the library +--------------------------------- + +The IJG JPEG library provides C code to read and write JPEG-compressed image +files. The surrounding application program receives or supplies image data a +scanline at a time, using a straightforward uncompressed image format. All +details of color conversion and other preprocessing/postprocessing can be +handled by the library. + +The library includes a substantial amount of code that is not covered by the +JPEG standard but is necessary for typical applications of JPEG. These +functions preprocess the image before JPEG compression or postprocess it after +decompression. They include colorspace conversion, downsampling/upsampling, +and color quantization. The application indirectly selects use of this code +by specifying the format in which it wishes to supply or receive image data. +For example, if colormapped output is requested, then the decompression +library automatically invokes color quantization. + +A wide range of quality vs. speed tradeoffs are possible in JPEG processing, +and even more so in decompression postprocessing. The decompression library +provides multiple implementations that cover most of the useful tradeoffs, +ranging from very-high-quality down to fast-preview operation. On the +compression side we have generally not provided low-quality choices, since +compression is normally less time-critical. It should be understood that the +low-quality modes may not meet the JPEG standard's accuracy requirements; +nonetheless, they are useful for viewers. + +A word about functions *not* provided by the library. We handle a subset of +the ISO JPEG standard; most baseline, extended-sequential, and progressive +JPEG processes are supported. (Our subset includes all features now in common +use.) Unsupported ISO options include: + * Hierarchical storage + * Lossless JPEG + * DNL marker + * Nonintegral subsampling ratios +We support 8-bit to 12-bit data precision, but this is a compile-time choice +rather than a run-time choice; hence it is difficult to use different +precisions in a single application. + +By itself, the library handles only interchange JPEG datastreams --- in +particular the widely used JFIF file format. The library can be used by +surrounding code to process interchange or abbreviated JPEG datastreams that +are embedded in more complex file formats. (For example, this library is +used by the free LIBTIFF library to support JPEG compression in TIFF.) + + +Outline of typical usage +------------------------ + +The rough outline of a JPEG compression operation is: + + Allocate and initialize a JPEG compression object + Specify the destination for the compressed data (eg, a file) + Set parameters for compression, including image size & colorspace + jpeg_start_compress(...); + while (scan lines remain to be written) + jpeg_write_scanlines(...); + jpeg_finish_compress(...); + Release the JPEG compression object + +A JPEG compression object holds parameters and working state for the JPEG +library. We make creation/destruction of the object separate from starting +or finishing compression of an image; the same object can be re-used for a +series of image compression operations. This makes it easy to re-use the +same parameter settings for a sequence of images. Re-use of a JPEG object +also has important implications for processing abbreviated JPEG datastreams, +as discussed later. + +The image data to be compressed is supplied to jpeg_write_scanlines() from +in-memory buffers. If the application is doing file-to-file compression, +reading image data from the source file is the application's responsibility. +The library emits compressed data by calling a "data destination manager", +which typically will write the data into a file; but the application can +provide its own destination manager to do something else. + +Similarly, the rough outline of a JPEG decompression operation is: + + Allocate and initialize a JPEG decompression object + Specify the source of the compressed data (eg, a file) + Call jpeg_read_header() to obtain image info + Set parameters for decompression + jpeg_start_decompress(...); + while (scan lines remain to be read) + jpeg_read_scanlines(...); + jpeg_finish_decompress(...); + Release the JPEG decompression object + +This is comparable to the compression outline except that reading the +datastream header is a separate step. This is helpful because information +about the image's size, colorspace, etc is available when the application +selects decompression parameters. For example, the application can choose an +output scaling ratio that will fit the image into the available screen size. + +The decompression library obtains compressed data by calling a data source +manager, which typically will read the data from a file; but other behaviors +can be obtained with a custom source manager. Decompressed data is delivered +into in-memory buffers passed to jpeg_read_scanlines(). + +It is possible to abort an incomplete compression or decompression operation +by calling jpeg_abort(); or, if you do not need to retain the JPEG object, +simply release it by calling jpeg_destroy(). + +JPEG compression and decompression objects are two separate struct types. +However, they share some common fields, and certain routines such as +jpeg_destroy() can work on either type of object. + +The JPEG library has no static variables: all state is in the compression +or decompression object. Therefore it is possible to process multiple +compression and decompression operations concurrently, using multiple JPEG +objects. + +Both compression and decompression can be done in an incremental memory-to- +memory fashion, if suitable source/destination managers are used. See the +section on "I/O suspension" for more details. + + +BASIC LIBRARY USAGE +=================== + +Data formats +------------ + +Before diving into procedural details, it is helpful to understand the +image data format that the JPEG library expects or returns. + +The standard input image format is a rectangular array of pixels, with each +pixel having the same number of "component" or "sample" values (color +channels). You must specify how many components there are and the colorspace +interpretation of the components. Most applications will use RGB data +(three components per pixel) or grayscale data (one component per pixel). +PLEASE NOTE THAT RGB DATA IS THREE SAMPLES PER PIXEL, GRAYSCALE ONLY ONE. +A remarkable number of people manage to miss this, only to find that their +programs don't work with grayscale JPEG files. + +There is no provision for colormapped input. JPEG files are always full-color +or full grayscale (or sometimes another colorspace such as CMYK). You can +feed in a colormapped image by expanding it to full-color format. However +JPEG often doesn't work very well with source data that has been colormapped, +because of dithering noise. This is discussed in more detail in the JPEG FAQ +and the other references mentioned in the README file. + +Pixels are stored by scanlines, with each scanline running from left to +right. The component values for each pixel are adjacent in the row; for +example, R,G,B,R,G,B,R,G,B,... for 24-bit RGB color. Each scanline is an +array of data type JSAMPLE --- which is typically "unsigned char", unless +you've changed jmorecfg.h. (You can also change the RGB pixel layout, say +to B,G,R order, by modifying jmorecfg.h. But see the restrictions listed in +that file before doing so.) + +A 2-D array of pixels is formed by making a list of pointers to the starts of +scanlines; so the scanlines need not be physically adjacent in memory. Even +if you process just one scanline at a time, you must make a one-element +pointer array to conform to this structure. Pointers to JSAMPLE rows are of +type JSAMPROW, and the pointer to the pointer array is of type JSAMPARRAY. + +The library accepts or supplies one or more complete scanlines per call. +It is not possible to process part of a row at a time. Scanlines are always +processed top-to-bottom. You can process an entire image in one call if you +have it all in memory, but usually it's simplest to process one scanline at +a time. + +For best results, source data values should have the precision specified by +BITS_IN_JSAMPLE (normally 8 bits). For instance, if you choose to compress +data that's only 6 bits/channel, you should left-justify each value in a +byte before passing it to the compressor. If you need to compress data +that has more than 8 bits/channel, compile with BITS_IN_JSAMPLE = 9 to 12. +(See "Library compile-time options", later.) + + +The data format returned by the decompressor is the same in all details, +except that colormapped output is supported. (Again, a JPEG file is never +colormapped. But you can ask the decompressor to perform on-the-fly color +quantization to deliver colormapped output.) If you request colormapped +output then the returned data array contains a single JSAMPLE per pixel; +its value is an index into a color map. The color map is represented as +a 2-D JSAMPARRAY in which each row holds the values of one color component, +that is, colormap[i][j] is the value of the i'th color component for pixel +value (map index) j. Note that since the colormap indexes are stored in +JSAMPLEs, the maximum number of colors is limited by the size of JSAMPLE +(ie, at most 256 colors for an 8-bit JPEG library). + + +Compression details +------------------- + +Here we revisit the JPEG compression outline given in the overview. + +1. Allocate and initialize a JPEG compression object. + +A JPEG compression object is a "struct jpeg_compress_struct". (It also has +a bunch of subsidiary structures which are allocated via malloc(), but the +application doesn't control those directly.) This struct can be just a local +variable in the calling routine, if a single routine is going to execute the +whole JPEG compression sequence. Otherwise it can be static or allocated +from malloc(). + +You will also need a structure representing a JPEG error handler. The part +of this that the library cares about is a "struct jpeg_error_mgr". If you +are providing your own error handler, you'll typically want to embed the +jpeg_error_mgr struct in a larger structure; this is discussed later under +"Error handling". For now we'll assume you are just using the default error +handler. The default error handler will print JPEG error/warning messages +on stderr, and it will call exit() if a fatal error occurs. + +You must initialize the error handler structure, store a pointer to it into +the JPEG object's "err" field, and then call jpeg_create_compress() to +initialize the rest of the JPEG object. + +Typical code for this step, if you are using the default error handler, is + + struct jpeg_compress_struct cinfo; + struct jpeg_error_mgr jerr; + ... + cinfo.err = jpeg_std_error(&jerr); + jpeg_create_compress(&cinfo); + +jpeg_create_compress allocates a small amount of memory, so it could fail +if you are out of memory. In that case it will exit via the error handler; +that's why the error handler must be initialized first. + + +2. Specify the destination for the compressed data (eg, a file). + +As previously mentioned, the JPEG library delivers compressed data to a +"data destination" module. The library includes one data destination +module which knows how to write to a stdio stream. You can use your own +destination module if you want to do something else, as discussed later. + +If you use the standard destination module, you must open the target stdio +stream beforehand. Typical code for this step looks like: + + FILE * outfile; + ... + if ((outfile = fopen(filename, "wb")) == NULL) { + fprintf(stderr, "can't open %s\n", filename); + exit(1); + } + jpeg_stdio_dest(&cinfo, outfile); + +where the last line invokes the standard destination module. + +WARNING: it is critical that the binary compressed data be delivered to the +output file unchanged. On non-Unix systems the stdio library may perform +newline translation or otherwise corrupt binary data. To suppress this +behavior, you may need to use a "b" option to fopen (as shown above), or use +setmode() or another routine to put the stdio stream in binary mode. See +cjpeg.c and djpeg.c for code that has been found to work on many systems. + +You can select the data destination after setting other parameters (step 3), +if that's more convenient. You may not change the destination between +calling jpeg_start_compress() and jpeg_finish_compress(). + + +3. Set parameters for compression, including image size & colorspace. + +You must supply information about the source image by setting the following +fields in the JPEG object (cinfo structure): + + image_width Width of image, in pixels + image_height Height of image, in pixels + input_components Number of color channels (samples per pixel) + in_color_space Color space of source image + +The image dimensions are, hopefully, obvious. JPEG supports image dimensions +of 1 to 64K pixels in either direction. The input color space is typically +RGB or grayscale, and input_components is 3 or 1 accordingly. (See "Special +color spaces", later, for more info.) The in_color_space field must be +assigned one of the J_COLOR_SPACE enum constants, typically JCS_RGB or +JCS_GRAYSCALE. + +JPEG has a large number of compression parameters that determine how the +image is encoded. Most applications don't need or want to know about all +these parameters. You can set all the parameters to reasonable defaults by +calling jpeg_set_defaults(); then, if there are particular values you want +to change, you can do so after that. The "Compression parameter selection" +section tells about all the parameters. + +You must set in_color_space correctly before calling jpeg_set_defaults(), +because the defaults depend on the source image colorspace. However the +other three source image parameters need not be valid until you call +jpeg_start_compress(). There's no harm in calling jpeg_set_defaults() more +than once, if that happens to be convenient. + +Typical code for a 24-bit RGB source image is + + cinfo.image_width = Width; /* image width and height, in pixels */ + cinfo.image_height = Height; + cinfo.input_components = 3; /* # of color components per pixel */ + cinfo.in_color_space = JCS_RGB; /* colorspace of input image */ + + jpeg_set_defaults(&cinfo); + /* Make optional parameter settings here */ + + +4. jpeg_start_compress(...); + +After you have established the data destination and set all the necessary +source image info and other parameters, call jpeg_start_compress() to begin +a compression cycle. This will initialize internal state, allocate working +storage, and emit the first few bytes of the JPEG datastream header. + +Typical code: + + jpeg_start_compress(&cinfo, TRUE); + +The "TRUE" parameter ensures that a complete JPEG interchange datastream +will be written. This is appropriate in most cases. If you think you might +want to use an abbreviated datastream, read the section on abbreviated +datastreams, below. + +Once you have called jpeg_start_compress(), you may not alter any JPEG +parameters or other fields of the JPEG object until you have completed +the compression cycle. + + +5. while (scan lines remain to be written) + jpeg_write_scanlines(...); + +Now write all the required image data by calling jpeg_write_scanlines() +one or more times. You can pass one or more scanlines in each call, up +to the total image height. In most applications it is convenient to pass +just one or a few scanlines at a time. The expected format for the passed +data is discussed under "Data formats", above. + +Image data should be written in top-to-bottom scanline order. The JPEG spec +contains some weasel wording about how top and bottom are application-defined +terms (a curious interpretation of the English language...) but if you want +your files to be compatible with everyone else's, you WILL use top-to-bottom +order. If the source data must be read in bottom-to-top order, you can use +the JPEG library's virtual array mechanism to invert the data efficiently. +Examples of this can be found in the sample application cjpeg. + +The library maintains a count of the number of scanlines written so far +in the next_scanline field of the JPEG object. Usually you can just use +this variable as the loop counter, so that the loop test looks like +"while (cinfo.next_scanline < cinfo.image_height)". + +Code for this step depends heavily on the way that you store the source data. +example.c shows the following code for the case of a full-size 2-D source +array containing 3-byte RGB pixels: + + JSAMPROW row_pointer[1]; /* pointer to a single row */ + int row_stride; /* physical row width in buffer */ + + row_stride = image_width * 3; /* JSAMPLEs per row in image_buffer */ + + while (cinfo.next_scanline < cinfo.image_height) { + row_pointer[0] = & image_buffer[cinfo.next_scanline * row_stride]; + jpeg_write_scanlines(&cinfo, row_pointer, 1); + } + +jpeg_write_scanlines() returns the number of scanlines actually written. +This will normally be equal to the number passed in, so you can usually +ignore the return value. It is different in just two cases: + * If you try to write more scanlines than the declared image height, + the additional scanlines are ignored. + * If you use a suspending data destination manager, output buffer overrun + will cause the compressor to return before accepting all the passed lines. + This feature is discussed under "I/O suspension", below. The normal + stdio destination manager will NOT cause this to happen. +In any case, the return value is the same as the change in the value of +next_scanline. + + +6. jpeg_finish_compress(...); + +After all the image data has been written, call jpeg_finish_compress() to +complete the compression cycle. This step is ESSENTIAL to ensure that the +last bufferload of data is written to the data destination. +jpeg_finish_compress() also releases working memory associated with the JPEG +object. + +Typical code: + + jpeg_finish_compress(&cinfo); + +If using the stdio destination manager, don't forget to close the output +stdio stream (if necessary) afterwards. + +If you have requested a multi-pass operating mode, such as Huffman code +optimization, jpeg_finish_compress() will perform the additional passes using +data buffered by the first pass. In this case jpeg_finish_compress() may take +quite a while to complete. With the default compression parameters, this will +not happen. + +It is an error to call jpeg_finish_compress() before writing the necessary +total number of scanlines. If you wish to abort compression, call +jpeg_abort() as discussed below. + +After completing a compression cycle, you may dispose of the JPEG object +as discussed next, or you may use it to compress another image. In that case +return to step 2, 3, or 4 as appropriate. If you do not change the +destination manager, the new datastream will be written to the same target. +If you do not change any JPEG parameters, the new datastream will be written +with the same parameters as before. Note that you can change the input image +dimensions freely between cycles, but if you change the input colorspace, you +should call jpeg_set_defaults() to adjust for the new colorspace; and then +you'll need to repeat all of step 3. + + +7. Release the JPEG compression object. + +When you are done with a JPEG compression object, destroy it by calling +jpeg_destroy_compress(). This will free all subsidiary memory (regardless of +the previous state of the object). Or you can call jpeg_destroy(), which +works for either compression or decompression objects --- this may be more +convenient if you are sharing code between compression and decompression +cases. (Actually, these routines are equivalent except for the declared type +of the passed pointer. To avoid gripes from ANSI C compilers, jpeg_destroy() +should be passed a j_common_ptr.) + +If you allocated the jpeg_compress_struct structure from malloc(), freeing +it is your responsibility --- jpeg_destroy() won't. Ditto for the error +handler structure. + +Typical code: + + jpeg_destroy_compress(&cinfo); + + +8. Aborting. + +If you decide to abort a compression cycle before finishing, you can clean up +in either of two ways: + +* If you don't need the JPEG object any more, just call + jpeg_destroy_compress() or jpeg_destroy() to release memory. This is + legitimate at any point after calling jpeg_create_compress() --- in fact, + it's safe even if jpeg_create_compress() fails. + +* If you want to re-use the JPEG object, call jpeg_abort_compress(), or call + jpeg_abort() which works on both compression and decompression objects. + This will return the object to an idle state, releasing any working memory. + jpeg_abort() is allowed at any time after successful object creation. + +Note that cleaning up the data destination, if required, is your +responsibility; neither of these routines will call term_destination(). +(See "Compressed data handling", below, for more about that.) + +jpeg_destroy() and jpeg_abort() are the only safe calls to make on a JPEG +object that has reported an error by calling error_exit (see "Error handling" +for more info). The internal state of such an object is likely to be out of +whack. Either of these two routines will return the object to a known state. + + +Decompression details +--------------------- + +Here we revisit the JPEG decompression outline given in the overview. + +1. Allocate and initialize a JPEG decompression object. + +This is just like initialization for compression, as discussed above, +except that the object is a "struct jpeg_decompress_struct" and you +call jpeg_create_decompress(). Error handling is exactly the same. + +Typical code: + + struct jpeg_decompress_struct cinfo; + struct jpeg_error_mgr jerr; + ... + cinfo.err = jpeg_std_error(&jerr); + jpeg_create_decompress(&cinfo); + +(Both here and in the IJG code, we usually use variable name "cinfo" for +both compression and decompression objects.) + + +2. Specify the source of the compressed data (eg, a file). + +As previously mentioned, the JPEG library reads compressed data from a "data +source" module. The library includes one data source module which knows how +to read from a stdio stream. You can use your own source module if you want +to do something else, as discussed later. + +If you use the standard source module, you must open the source stdio stream +beforehand. Typical code for this step looks like: + + FILE * infile; + ... + if ((infile = fopen(filename, "rb")) == NULL) { + fprintf(stderr, "can't open %s\n", filename); + exit(1); + } + jpeg_stdio_src(&cinfo, infile); + +where the last line invokes the standard source module. + +WARNING: it is critical that the binary compressed data be read unchanged. +On non-Unix systems the stdio library may perform newline translation or +otherwise corrupt binary data. To suppress this behavior, you may need to use +a "b" option to fopen (as shown above), or use setmode() or another routine to +put the stdio stream in binary mode. See cjpeg.c and djpeg.c for code that +has been found to work on many systems. + +You may not change the data source between calling jpeg_read_header() and +jpeg_finish_decompress(). If you wish to read a series of JPEG images from +a single source file, you should repeat the jpeg_read_header() to +jpeg_finish_decompress() sequence without reinitializing either the JPEG +object or the data source module; this prevents buffered input data from +being discarded. + + +3. Call jpeg_read_header() to obtain image info. + +Typical code for this step is just + + jpeg_read_header(&cinfo, TRUE); + +This will read the source datastream header markers, up to the beginning +of the compressed data proper. On return, the image dimensions and other +info have been stored in the JPEG object. The application may wish to +consult this information before selecting decompression parameters. + +More complex code is necessary if + * A suspending data source is used --- in that case jpeg_read_header() + may return before it has read all the header data. See "I/O suspension", + below. The normal stdio source manager will NOT cause this to happen. + * Abbreviated JPEG files are to be processed --- see the section on + abbreviated datastreams. Standard applications that deal only in + interchange JPEG files need not be concerned with this case either. + +It is permissible to stop at this point if you just wanted to find out the +image dimensions and other header info for a JPEG file. In that case, +call jpeg_destroy() when you are done with the JPEG object, or call +jpeg_abort() to return it to an idle state before selecting a new data +source and reading another header. + + +4. Set parameters for decompression. + +jpeg_read_header() sets appropriate default decompression parameters based on +the properties of the image (in particular, its colorspace). However, you +may well want to alter these defaults before beginning the decompression. +For example, the default is to produce full color output from a color file. +If you want colormapped output you must ask for it. Other options allow the +returned image to be scaled and allow various speed/quality tradeoffs to be +selected. "Decompression parameter selection", below, gives details. + +If the defaults are appropriate, nothing need be done at this step. + +Note that all default values are set by each call to jpeg_read_header(). +If you reuse a decompression object, you cannot expect your parameter +settings to be preserved across cycles, as you can for compression. +You must set desired parameter values each time. + + +5. jpeg_start_decompress(...); + +Once the parameter values are satisfactory, call jpeg_start_decompress() to +begin decompression. This will initialize internal state, allocate working +memory, and prepare for returning data. + +Typical code is just + + jpeg_start_decompress(&cinfo); + +If you have requested a multi-pass operating mode, such as 2-pass color +quantization, jpeg_start_decompress() will do everything needed before data +output can begin. In this case jpeg_start_decompress() may take quite a while +to complete. With a single-scan (non progressive) JPEG file and default +decompression parameters, this will not happen; jpeg_start_decompress() will +return quickly. + +After this call, the final output image dimensions, including any requested +scaling, are available in the JPEG object; so is the selected colormap, if +colormapped output has been requested. Useful fields include + + output_width image width and height, as scaled + output_height + out_color_components # of color components in out_color_space + output_components # of color components returned per pixel + colormap the selected colormap, if any + actual_number_of_colors number of entries in colormap + +output_components is 1 (a colormap index) when quantizing colors; otherwise it +equals out_color_components. It is the number of JSAMPLE values that will be +emitted per pixel in the output arrays. + +Typically you will need to allocate data buffers to hold the incoming image. +You will need output_width * output_components JSAMPLEs per scanline in your +output buffer, and a total of output_height scanlines will be returned. + +Note: if you are using the JPEG library's internal memory manager to allocate +data buffers (as djpeg does), then the manager's protocol requires that you +request large buffers *before* calling jpeg_start_decompress(). This is a +little tricky since the output_XXX fields are not normally valid then. You +can make them valid by calling jpeg_calc_output_dimensions() after setting the +relevant parameters (scaling, output color space, and quantization flag). + + +6. while (scan lines remain to be read) + jpeg_read_scanlines(...); + +Now you can read the decompressed image data by calling jpeg_read_scanlines() +one or more times. At each call, you pass in the maximum number of scanlines +to be read (ie, the height of your working buffer); jpeg_read_scanlines() +will return up to that many lines. The return value is the number of lines +actually read. The format of the returned data is discussed under "Data +formats", above. Don't forget that grayscale and color JPEGs will return +different data formats! + +Image data is returned in top-to-bottom scanline order. If you must write +out the image in bottom-to-top order, you can use the JPEG library's virtual +array mechanism to invert the data efficiently. Examples of this can be +found in the sample application djpeg. + +The library maintains a count of the number of scanlines returned so far +in the output_scanline field of the JPEG object. Usually you can just use +this variable as the loop counter, so that the loop test looks like +"while (cinfo.output_scanline < cinfo.output_height)". (Note that the test +should NOT be against image_height, unless you never use scaling. The +image_height field is the height of the original unscaled image.) +The return value always equals the change in the value of output_scanline. + +If you don't use a suspending data source, it is safe to assume that +jpeg_read_scanlines() reads at least one scanline per call, until the +bottom of the image has been reached. + +If you use a buffer larger than one scanline, it is NOT safe to assume that +jpeg_read_scanlines() fills it. (The current implementation returns only a +few scanlines per call, no matter how large a buffer you pass.) So you must +always provide a loop that calls jpeg_read_scanlines() repeatedly until the +whole image has been read. + + +7. jpeg_finish_decompress(...); + +After all the image data has been read, call jpeg_finish_decompress() to +complete the decompression cycle. This causes working memory associated +with the JPEG object to be released. + +Typical code: + + jpeg_finish_decompress(&cinfo); + +If using the stdio source manager, don't forget to close the source stdio +stream if necessary. + +It is an error to call jpeg_finish_decompress() before reading the correct +total number of scanlines. If you wish to abort decompression, call +jpeg_abort() as discussed below. + +After completing a decompression cycle, you may dispose of the JPEG object as +discussed next, or you may use it to decompress another image. In that case +return to step 2 or 3 as appropriate. If you do not change the source +manager, the next image will be read from the same source. + + +8. Release the JPEG decompression object. + +When you are done with a JPEG decompression object, destroy it by calling +jpeg_destroy_decompress() or jpeg_destroy(). The previous discussion of +destroying compression objects applies here too. + +Typical code: + + jpeg_destroy_decompress(&cinfo); + + +9. Aborting. + +You can abort a decompression cycle by calling jpeg_destroy_decompress() or +jpeg_destroy() if you don't need the JPEG object any more, or +jpeg_abort_decompress() or jpeg_abort() if you want to reuse the object. +The previous discussion of aborting compression cycles applies here too. + + +Mechanics of usage: include files, linking, etc +----------------------------------------------- + +Applications using the JPEG library should include the header file jpeglib.h +to obtain declarations of data types and routines. Before including +jpeglib.h, include system headers that define at least the typedefs FILE and +size_t. On ANSI-conforming systems, including is sufficient; on +older Unix systems, you may need to define size_t. + +If the application needs to refer to individual JPEG library error codes, also +include jerror.h to define those symbols. + +jpeglib.h indirectly includes the files jconfig.h and jmorecfg.h. If you are +installing the JPEG header files in a system directory, you will want to +install all four files: jpeglib.h, jerror.h, jconfig.h, jmorecfg.h. + +The most convenient way to include the JPEG code into your executable program +is to prepare a library file ("libjpeg.a", or a corresponding name on non-Unix +machines) and reference it at your link step. If you use only half of the +library (only compression or only decompression), only that much code will be +included from the library, unless your linker is hopelessly brain-damaged. +The supplied makefiles build libjpeg.a automatically (see install.txt). + +While you can build the JPEG library as a shared library if the whim strikes +you, we don't really recommend it. The trouble with shared libraries is that +at some point you'll probably try to substitute a new version of the library +without recompiling the calling applications. That generally doesn't work +because the parameter struct declarations usually change with each new +version. In other words, the library's API is *not* guaranteed binary +compatible across versions; we only try to ensure source-code compatibility. +(In hindsight, it might have been smarter to hide the parameter structs from +applications and introduce a ton of access functions instead. Too late now, +however.) + +On some systems your application may need to set up a signal handler to ensure +that temporary files are deleted if the program is interrupted. This is most +critical if you are on MS-DOS and use the jmemdos.c memory manager back end; +it will try to grab extended memory for temp files, and that space will NOT be +freed automatically. See cjpeg.c or djpeg.c for an example signal handler. + +It may be worth pointing out that the core JPEG library does not actually +require the stdio library: only the default source/destination managers and +error handler need it. You can use the library in a stdio-less environment +if you replace those modules and use jmemnobs.c (or another memory manager of +your own devising). More info about the minimum system library requirements +may be found in jinclude.h. + + +ADVANCED FEATURES +================= + +Compression parameter selection +------------------------------- + +This section describes all the optional parameters you can set for JPEG +compression, as well as the "helper" routines provided to assist in this +task. Proper setting of some parameters requires detailed understanding +of the JPEG standard; if you don't know what a parameter is for, it's best +not to mess with it! See REFERENCES in the README file for pointers to +more info about JPEG. + +It's a good idea to call jpeg_set_defaults() first, even if you plan to set +all the parameters; that way your code is more likely to work with future JPEG +libraries that have additional parameters. For the same reason, we recommend +you use a helper routine where one is provided, in preference to twiddling +cinfo fields directly. + +The helper routines are: + +jpeg_set_defaults (j_compress_ptr cinfo) + This routine sets all JPEG parameters to reasonable defaults, using + only the input image's color space (field in_color_space, which must + already be set in cinfo). Many applications will only need to use + this routine and perhaps jpeg_set_quality(). + +jpeg_set_colorspace (j_compress_ptr cinfo, J_COLOR_SPACE colorspace) + Sets the JPEG file's colorspace (field jpeg_color_space) as specified, + and sets other color-space-dependent parameters appropriately. See + "Special color spaces", below, before using this. A large number of + parameters, including all per-component parameters, are set by this + routine; if you want to twiddle individual parameters you should call + jpeg_set_colorspace() before rather than after. + +jpeg_default_colorspace (j_compress_ptr cinfo) + Selects an appropriate JPEG colorspace based on cinfo->in_color_space, + and calls jpeg_set_colorspace(). This is actually a subroutine of + jpeg_set_defaults(). It's broken out in case you want to change + just the colorspace-dependent JPEG parameters. + +jpeg_set_quality (j_compress_ptr cinfo, int quality, boolean force_baseline) + Constructs JPEG quantization tables appropriate for the indicated + quality setting. The quality value is expressed on the 0..100 scale + recommended by IJG (cjpeg's "-quality" switch uses this routine). + Note that the exact mapping from quality values to tables may change + in future IJG releases as more is learned about DCT quantization. + If the force_baseline parameter is TRUE, then the quantization table + entries are constrained to the range 1..255 for full JPEG baseline + compatibility. In the current implementation, this only makes a + difference for quality settings below 25, and it effectively prevents + very small/low quality files from being generated. The IJG decoder + is capable of reading the non-baseline files generated at low quality + settings when force_baseline is FALSE, but other decoders may not be. + +jpeg_set_linear_quality (j_compress_ptr cinfo, int scale_factor, + boolean force_baseline) + Same as jpeg_set_quality() except that the generated tables are the + sample tables given in the JPEC spec section K.1, multiplied by the + specified scale factor (which is expressed as a percentage; thus + scale_factor = 100 reproduces the spec's tables). Note that larger + scale factors give lower quality. This entry point is useful for + conforming to the Adobe PostScript DCT conventions, but we do not + recommend linear scaling as a user-visible quality scale otherwise. + force_baseline again constrains the computed table entries to 1..255. + +int jpeg_quality_scaling (int quality) + Converts a value on the IJG-recommended quality scale to a linear + scaling percentage. Note that this routine may change or go away + in future releases --- IJG may choose to adopt a scaling method that + can't be expressed as a simple scalar multiplier, in which case the + premise of this routine collapses. Caveat user. + +jpeg_default_qtables (j_compress_ptr cinfo, boolean force_baseline) + Set default quantization tables with linear q_scale_factor[] values + (see below). + +jpeg_add_quant_table (j_compress_ptr cinfo, int which_tbl, + const unsigned int *basic_table, + int scale_factor, boolean force_baseline) + Allows an arbitrary quantization table to be created. which_tbl + indicates which table slot to fill. basic_table points to an array + of 64 unsigned ints given in normal array order. These values are + multiplied by scale_factor/100 and then clamped to the range 1..65535 + (or to 1..255 if force_baseline is TRUE). + CAUTION: prior to library version 6a, jpeg_add_quant_table expected + the basic table to be given in JPEG zigzag order. If you need to + write code that works with either older or newer versions of this + routine, you must check the library version number. Something like + "#if JPEG_LIB_VERSION >= 61" is the right test. + +jpeg_simple_progression (j_compress_ptr cinfo) + Generates a default scan script for writing a progressive-JPEG file. + This is the recommended method of creating a progressive file, + unless you want to make a custom scan sequence. You must ensure that + the JPEG color space is set correctly before calling this routine. + + +Compression parameters (cinfo fields) include: + +boolean arith_code + If TRUE, use arithmetic coding. + If FALSE, use Huffman coding. + +int block_size + Set DCT block size. All N from 1 to 16 are possible. + Default is 8 (baseline format). + Larger values produce higher compression, + smaller values produce higher quality. + An exact DCT stage is possible with 1 or 2. + With the default quality of 75 and default Luminance qtable + the DCT+Quantization stage is lossless for value 1. + Note that values other than 8 require a SmartScale capable decoder, + introduced with IJG JPEG 8. Setting the block_size parameter for + compression works with version 8c and later. + +J_DCT_METHOD dct_method + Selects the algorithm used for the DCT step. Choices are: + JDCT_ISLOW: slow but accurate integer algorithm + JDCT_IFAST: faster, less accurate integer method + JDCT_FLOAT: floating-point method + JDCT_DEFAULT: default method (normally JDCT_ISLOW) + JDCT_FASTEST: fastest method (normally JDCT_IFAST) + The FLOAT method is very slightly more accurate than the ISLOW method, + but may give different results on different machines due to varying + roundoff behavior. The integer methods should give the same results + on all machines. On machines with sufficiently fast FP hardware, the + floating-point method may also be the fastest. The IFAST method is + considerably less accurate than the other two; its use is not + recommended if high quality is a concern. JDCT_DEFAULT and + JDCT_FASTEST are macros configurable by each installation. + +unsigned int scale_num, scale_denom + Scale the image by the fraction scale_num/scale_denom. Default is + 1/1, or no scaling. Currently, the supported scaling ratios are + M/N with all N from 1 to 16, where M is the destination DCT size, + which is 8 by default (see block_size parameter above). + (The library design allows for arbitrary scaling ratios but this + is not likely to be implemented any time soon.) + +J_COLOR_SPACE jpeg_color_space +int num_components + The JPEG color space and corresponding number of components; see + "Special color spaces", below, for more info. We recommend using + jpeg_set_colorspace() if you want to change these. + +J_COLOR_TRANSFORM color_transform + Internal color transform identifier, writes LSE marker if nonzero + (requires decoder with inverse color transform support, introduced + with IJG JPEG 9). + Two values are currently possible: JCT_NONE and JCT_SUBTRACT_GREEN. + Set this value for lossless RGB application *before* calling + jpeg_set_colorspace(), because entropy table assignment in + jpeg_set_colorspace() depends on color_transform. + +boolean optimize_coding + TRUE causes the compressor to compute optimal Huffman coding tables + for the image. This requires an extra pass over the data and + therefore costs a good deal of space and time. The default is + FALSE, which tells the compressor to use the supplied or default + Huffman tables. In most cases optimal tables save only a few percent + of file size compared to the default tables. Note that when this is + TRUE, you need not supply Huffman tables at all, and any you do + supply will be overwritten. + +unsigned int restart_interval +int restart_in_rows + To emit restart markers in the JPEG file, set one of these nonzero. + Set restart_interval to specify the exact interval in MCU blocks. + Set restart_in_rows to specify the interval in MCU rows. (If + restart_in_rows is not 0, then restart_interval is set after the + image width in MCUs is computed.) Defaults are zero (no restarts). + One restart marker per MCU row is often a good choice. + NOTE: the overhead of restart markers is higher in grayscale JPEG + files than in color files, and MUCH higher in progressive JPEGs. + If you use restarts, you may want to use larger intervals in those + cases. + +const jpeg_scan_info * scan_info +int num_scans + By default, scan_info is NULL; this causes the compressor to write a + single-scan sequential JPEG file. If not NULL, scan_info points to + an array of scan definition records of length num_scans. The + compressor will then write a JPEG file having one scan for each scan + definition record. This is used to generate noninterleaved or + progressive JPEG files. The library checks that the scan array + defines a valid JPEG scan sequence. (jpeg_simple_progression creates + a suitable scan definition array for progressive JPEG.) This is + discussed further under "Progressive JPEG support". + +boolean do_fancy_downsampling + If TRUE, use direct DCT scaling with DCT size > 8 for downsampling + of chroma components. + If FALSE, use only DCT size <= 8 and simple separate downsampling. + Default is TRUE. + For better image stability in multiple generation compression cycles + it is preferable that this value matches the corresponding + do_fancy_upsampling value in decompression. + +int smoothing_factor + If non-zero, the input image is smoothed; the value should be 1 for + minimal smoothing to 100 for maximum smoothing. Consult jcsample.c + for details of the smoothing algorithm. The default is zero. + +boolean write_JFIF_header + If TRUE, a JFIF APP0 marker is emitted. jpeg_set_defaults() and + jpeg_set_colorspace() set this TRUE if a JFIF-legal JPEG color space + (ie, YCbCr or grayscale) is selected, otherwise FALSE. + +UINT8 JFIF_major_version +UINT8 JFIF_minor_version + The version number to be written into the JFIF marker. + jpeg_set_defaults() initializes the version to 1.01 (major=minor=1). + You should set it to 1.02 (major=1, minor=2) if you plan to write + any JFIF 1.02 extension markers. + +UINT8 density_unit +UINT16 X_density +UINT16 Y_density + The resolution information to be written into the JFIF marker; + not used otherwise. density_unit may be 0 for unknown, + 1 for dots/inch, or 2 for dots/cm. The default values are 0,1,1 + indicating square pixels of unknown size. + +boolean write_Adobe_marker + If TRUE, an Adobe APP14 marker is emitted. jpeg_set_defaults() and + jpeg_set_colorspace() set this TRUE if JPEG color space RGB, CMYK, + or YCCK is selected, otherwise FALSE. It is generally a bad idea + to set both write_JFIF_header and write_Adobe_marker. In fact, + you probably shouldn't change the default settings at all --- the + default behavior ensures that the JPEG file's color space can be + recognized by the decoder. + +JQUANT_TBL * quant_tbl_ptrs[NUM_QUANT_TBLS] + Pointers to coefficient quantization tables, one per table slot, + or NULL if no table is defined for a slot. Usually these should + be set via one of the above helper routines; jpeg_add_quant_table() + is general enough to define any quantization table. The other + routines will set up table slot 0 for luminance quality and table + slot 1 for chrominance. + +int q_scale_factor[NUM_QUANT_TBLS] + Linear quantization scaling factors (percentage, initialized 100) + for use with jpeg_default_qtables(). + See rdswitch.c and cjpeg.c for an example of usage. + Note that the q_scale_factor[] fields are the "linear" scales, so you + have to convert from user-defined ratings via jpeg_quality_scaling(). + Here is an example code which corresponds to cjpeg -quality 90,70: + + jpeg_set_defaults(cinfo); + + /* Set luminance quality 90. */ + cinfo->q_scale_factor[0] = jpeg_quality_scaling(90); + /* Set chrominance quality 70. */ + cinfo->q_scale_factor[1] = jpeg_quality_scaling(70); + + jpeg_default_qtables(cinfo, force_baseline); + + CAUTION: You must also set 1x1 subsampling for efficient separate + color quality selection, since the default value used by library + is 2x2: + + cinfo->comp_info[0].v_samp_factor = 1; + cinfo->comp_info[0].h_samp_factor = 1; + +JHUFF_TBL * dc_huff_tbl_ptrs[NUM_HUFF_TBLS] +JHUFF_TBL * ac_huff_tbl_ptrs[NUM_HUFF_TBLS] + Pointers to Huffman coding tables, one per table slot, or NULL if + no table is defined for a slot. Slots 0 and 1 are filled with the + JPEG sample tables by jpeg_set_defaults(). If you need to allocate + more table structures, jpeg_alloc_huff_table() may be used. + Note that optimal Huffman tables can be computed for an image + by setting optimize_coding, as discussed above; there's seldom + any need to mess with providing your own Huffman tables. + + +The actual dimensions of the JPEG image that will be written to the file are +given by the following fields. These are computed from the input image +dimensions and the compression parameters by jpeg_start_compress(). You can +also call jpeg_calc_jpeg_dimensions() to obtain the values that will result +from the current parameter settings.

Decompression parameters control +the postprocessing done on the image to deliver it in a format suitable +for the application's use. Many of the parameters control speed/quality +tradeoffs, in which faster decompression may be obtained at the price of +a poorer-quality image. The defaults select the highest quality (slowest) +processing. + +The following fields in the JPEG object are set by jpeg_read_header() and +may be useful to the application in choosing decompression parameters: + +JDIMENSION image_width Width and height of image +JDIMENSION image_height +int num_components Number of color components +J_COLOR_SPACE jpeg_color_space Colorspace of image +boolean saw_JFIF_marker TRUE if a JFIF APP0 marker was seen + UINT8 JFIF_major_version Version information from JFIF marker + UINT8 JFIF_minor_version + UINT8 density_unit Resolution data from JFIF marker + UINT16 X_density + UINT16 Y_density +boolean saw_Adobe_marker TRUE if an Adobe APP14 marker was seen + UINT8 Adobe_transform Color transform code from Adobe marker + +The JPEG color space, unfortunately, is something of a guess since the JPEG +standard proper does not provide a way to record it. In practice most files +adhere to the JFIF or Adobe conventions, and the decoder will recognize these +correctly. See "Special color spaces", below, for more info. + + +The decompression parameters that determine the basic properties of the +returned image are: + +J_COLOR_SPACE out_color_space + Output color space. jpeg_read_header() sets an appropriate default + based on jpeg_color_space; typically it will be RGB or grayscale. + The application can change this field to request output in a different + colorspace. For example, set it to JCS_GRAYSCALE to get grayscale + output from a color file. (This is useful for previewing: grayscale + output is faster than full color since the color components need not + be processed.) Note that not all possible color space transforms are + currently implemented; you may need to extend jdcolor.c if you want an + unusual conversion. + +unsigned int scale_num, scale_denom + Scale the image by the fraction scale_num/scale_denom. Currently, + the supported scaling ratios are M/N with all M from 1 to 16, where + N is the source DCT size, which is 8 for baseline JPEG. (The library + design allows for arbitrary scaling ratios but this is not likely + to be implemented any time soon.) The values are initialized by + jpeg_read_header() with the source DCT size. For baseline JPEG + this is 8/8. If you change only the scale_num value while leaving + the other unchanged, then this specifies the DCT scaled size to be + applied on the given input. For baseline JPEG this is equivalent + to M/8 scaling, since the source DCT size for baseline JPEG is 8. + Smaller scaling ratios permit significantly faster decoding since + fewer pixels need be processed and a simpler IDCT method can be used. + +boolean quantize_colors + If set TRUE, colormapped output will be delivered.

Ignored when the application supplies its own color map. + +boolean two_pass_quantize + If TRUE, an extra pass over the image is made to select a custom color + map for the image. This usually looks a lot better than the one-size- + fits-all colormap that is used otherwise. Default is TRUE.

Supported values are: + JDITHER_NONE no dithering: fast, very low quality + JDITHER_ORDERED ordered dither: moderate speed and quality + JDITHER_FS Floyd-Steinberg dither: slow, high quality + Default is JDITHER_FS. (At present, ordered dither is implemented + only in the single-pass, standard-colormap case. If you ask for + ordered dither when two_pass_quantize is TRUE or when you supply + an external color map, you'll get F-S dithering.) + +When quantize_colors is TRUE, the target color map is described by the next +two fields. colormap is set to NULL by jpeg_read_header(). The application +can supply a color map by setting colormap non-NULL and setting +actual_number_of_colors to the map size. Otherwise, jpeg_start_decompress() +selects a suitable color map and sets these two fields itself. +[Implementation restriction: at present, an externally supplied colormap is +only accepted for 3-component output color spaces.] + +JSAMPARRAY colormap + The color map, represented as a 2-D pixel array of out_color_components + rows and actual_number_of_colors columns. Ignored if not quantizing. + CAUTION: if the JPEG library creates its own colormap, the storage + pointed to by this field is released by jpeg_finish_decompress(). + Copy the colormap somewhere else first, if you want to save it. + +int actual_number_of_colors + The number of colors in the color map. + +Additional decompression parameters that the application may set include: + +J_DCT_METHOD dct_method + Selects the algorithm used for the DCT step. Choices are the same + as described above for compression. + +boolean do_fancy_upsampling + If TRUE, use direct DCT scaling with DCT size > 8 for upsampling + of chroma components. + If FALSE, use only DCT size <= 8 and simple separate upsampling. + Default is TRUE. + For better image stability in multiple generation compression cycles + it is preferable that this value matches the corresponding + do_fancy_downsampling value in compression. + +boolean do_block_smoothing + If TRUE, interblock smoothing is applied in early stages of decoding + progressive JPEG files; if FALSE, not. Default is TRUE. Early + progression stages look "fuzzy" with smoothing, "blocky" without. + In any case, block smoothing ceases to be applied after the first few + AC coefficients are known to full accuracy, so it is relevant only + when using buffered-image mode for progressive images. + +boolean enable_1pass_quant +boolean enable_external_quant +boolean enable_2pass_quant + These are significant only in buffered-image mode, which is + described in its own section below. + + +The output image dimensions are given by the following fields. These are +computed from the source image dimensions and the decompression parameters +by jpeg_start_decompress(). You can also call jpeg_calc_output_dimensions() +to obtain the values that will result from the current parameter settings. +This can be useful if you are trying to pick a scaling ratio that will get +close to a desired target size. It's also important if you are using the +JPEG library's memory manager to allocate output buffer space, because you +are supposed to request such buffers *before* jpeg_start_decompress(). + +JDIMENSION output_width Actual dimensions of output image. +JDIMENSION output_height +int out_color_components Number of color components in out_color_space. +int output_components Number of color components returned. +int rec_outbuf_height Recommended height of scanline buffer. + +When quantizing colors, output_components is 1, indicating a single color map +index per pixel. Otherwise it equals out_color_components. The output arrays +are required to be output_width * output_components JSAMPLEs wide. + +rec_outbuf_height is the recommended minimum height (in scanlines) of the +buffer passed to jpeg_read_scanlines(). If the buffer is smaller, the +library will still work, but time will be wasted due to unnecessary data +copying. In high-quality modes, rec_outbuf_height is always 1, but some +faster, lower-quality modes set it to larger values (typically 2 to 4). +If you are going to ask for a high-speed processing mode, you may as well +go to the trouble of honoring rec_outbuf_height so as to avoid data copying. +(An output buffer larger than rec_outbuf_height lines is OK, but won't +provide any material speed improvement over that height.) + + +Special color spaces +-------------------- + +The JPEG standard itself is "color blind" and doesn't specify any particular +color space. It is customary to convert color data to a luminance/chrominance +color space before compressing, since this permits greater compression. The +existing JPEG file interchange format standards specify YCbCr or GRAYSCALE +data (JFIF version 1), GRAYSCALE, RGB, YCbCr, CMYK, or YCCK (Adobe), or BG_RGB +or BG_YCC (big gamut color spaces, JFIF version 2). For special applications +such as multispectral images, other color spaces can be used, +but it must be understood that such files will be unportable. + +The JPEG library can handle the most common colorspace conversions (namely +RGB <=> YCbCr and CMYK <=> YCCK). It can also deal with data of an unknown +color space, passing it through without conversion. If you deal extensively +with an unusual color space, you can easily extend the library to understand +additional color spaces and perform appropriate conversions. + +For compression, the source data's color space is specified by field +in_color_space. This is transformed to the JPEG file's color space given +by jpeg_color_space. jpeg_set_defaults() chooses a reasonable JPEG color +space depending on in_color_space, but you can override this by calling +jpeg_set_colorspace(). Of course you must select a supported transformation. +jccolor.c currently supports the following transformations: + RGB => YCbCr + RGB => GRAYSCALE + RGB => BG_YCC + YCbCr => GRAYSCALE + YCbCr => BG_YCC + CMYK => YCCK +plus the null transforms: GRAYSCALE => GRAYSCALE, RGB => RGB, +BG_RGB => BG_RGB, YCbCr => YCbCr, BG_YCC => BG_YCC, CMYK => CMYK, +YCCK => YCCK, and UNKNOWN => UNKNOWN. + +The file interchange format standards (JFIF and Adobe) specify APPn markers +that indicate the color space of the JPEG file. It is important to ensure +that these are written correctly, or omitted if the JPEG file's color space +is not one of the ones supported by the interchange standards. +jpeg_set_colorspace() will set the compression parameters to include or omit +the APPn markers properly, so long as it is told the truth about the JPEG +color space. For example, if you are writing some random 3-component color +space without conversion, don't try to fake out the library by setting +in_color_space and jpeg_color_space to JCS_YCbCr; use JCS_UNKNOWN. +You may want to write an APPn marker of your own devising to identify +the colorspace --- see "Special markers", below. + +When told that the color space is UNKNOWN, the library will default to using +luminance-quality compression parameters for all color components. You may +well want to change these parameters. See the source code for +jpeg_set_colorspace(), in jcparam.c, for details. + +For decompression, the JPEG file's color space is given in jpeg_color_space, +and this is transformed to the output color space out_color_space. +jpeg_read_header's setting of jpeg_color_space can be relied on if the file +conforms to JFIF or Adobe conventions, but otherwise it is no better than a +guess. If you know the JPEG file's color space for certain, you can override +jpeg_read_header's guess by setting jpeg_color_space. jpeg_read_header also +selects a default output color space based on (its guess of) jpeg_color_space; +set out_color_space to override this. Again, you must select a supported +transformation. jdcolor.c currently supports + YCbCr => RGB + YCbCr => GRAYSCALE + BG_YCC => RGB + BG_YCC => GRAYSCALE + RGB => GRAYSCALE + GRAYSCALE => RGB + YCCK => CMYK +as well as the null transforms. (Since GRAYSCALE=>RGB is provided, an +application can force grayscale JPEGs to look like color JPEGs if it only +wants to handle one case.) + +The two-pass color quantizer, jquant2.c, is specialized to handle RGB data +(it weights distances appropriately for RGB colors). You'll need to modify +the code if you want to use it for non-RGB output color spaces. Note that +jquant2.c is used to map to an application-supplied colormap as well as for +the normal two-pass colormap selection process. + +CAUTION: it appears that Adobe Photoshop writes inverted data in CMYK JPEG +files: 0 represents 100% ink coverage, rather than 0% ink as you'd expect. +This is arguably a bug in Photoshop, but if you need to work with Photoshop +CMYK files, you will have to deal with it in your application. We cannot +"fix" this in the library by inverting the data during the CMYK<=>YCCK +transform, because that would break other applications, notably Ghostscript. +Photoshop versions prior to 3.0 write EPS files containing JPEG-encoded CMYK +data in the same inverted-YCCK representation used in bare JPEG files, but +the surrounding PostScript code performs an inversion using the PS image +operator. I am told that Photoshop 3.0 will write uninverted YCCK in +EPS/JPEG files, and will omit the PS-level inversion. (But the data +polarity used in bare JPEG files will not change in 3.0.) In either case, +the JPEG library must not invert the data itself, or else Ghostscript would +read these EPS files incorrectly. + + +Error handling +-------------- + +When the default error handler is used, any error detected inside the JPEG +routines will cause a message to be printed on stderr, followed by exit(). +You can supply your own error handling routines to override this behavior +and to control the treatment of nonfatal warnings and trace/debug messages. +The file example.c illustrates the most common case, which is to have the +application regain control after an error rather than exiting. + +The JPEG library never writes any message directly; it always goes through +the error handling routines. Three classes of messages are recognized: + * Fatal errors: the library cannot continue. + * Warnings: the library can continue, but the data is corrupt, and a + damaged output image is likely to result. + * Trace/informational messages. These come with a trace level indicating + the importance of the message; you can control the verbosity of the + program by adjusting the maximum trace level that will be displayed. + +You may, if you wish, simply replace the entire JPEG error handling module +(jerror.c) with your own code. However, you can avoid code duplication by +only replacing some of the routines depending on the behavior you need. +This is accomplished by calling jpeg_std_error() as usual, but then overriding +some of the method pointers in the jpeg_error_mgr struct, as illustrated by +example.c. + +All of the error handling routines will receive a pointer to the JPEG object +(a j_common_ptr which points to either a jpeg_compress_struct or a +jpeg_decompress_struct; if you need to tell which, test the is_decompressor +field). This struct includes a pointer to the error manager struct in its +"err" field. Frequently, custom error handler routines will need to access +additional data which is not known to the JPEG library or the standard error +handler. The most convenient way to do this is to embed either the JPEG +object or the jpeg_error_mgr struct in a larger structure that contains +additional fields; then casting the passed pointer provides access to the +additional fields. Again, see example.c for one way to do it. (Beginning +with IJG version 6b, there is also a void pointer "client_data" in each +JPEG object, which the application can also use to find related data. +The library does not touch client_data at all.) + +The individual methods that you might wish to override are: + +error_exit (j_common_ptr cinfo) + Receives control for a fatal error. Information sufficient to + generate the error message has been stored in cinfo->err; call + output_message to display it. Control must NOT return to the caller; + generally this routine will exit() or longjmp() somewhere. + Typically you would override this routine to get rid of the exit() + default behavior. Note that if you continue processing, you should + clean up the JPEG object with jpeg_abort() or jpeg_destroy(). + +output_message (j_common_ptr cinfo) + Actual output of any JPEG message. Override this to send messages + somewhere other than stderr. Note that this method does not know + how to generate a message, only where to send it. + +format_message (j_common_ptr cinfo, char * buffer) + Constructs a readable error message string based on the error info + stored in cinfo->err. This method is called by output_message. Few + applications should need to override this method. One possible + reason for doing so is to implement dynamic switching of error message + language. + +emit_message (j_common_ptr cinfo, int msg_level) + Decide whether or not to emit a warning or trace message; if so, + calls output_message. The main reason for overriding this method + would be to abort on warnings. msg_level is -1 for warnings, + 0 and up for trace messages. + +Only error_exit() and emit_message() are called from the rest of the JPEG +library; the other two are internal to the error handler. + +The actual message texts are stored in an array of strings which is pointed to +by the field err->jpeg_message_table. The messages are numbered from 0 to +err->last_jpeg_message, and it is these code numbers that are used in the +JPEG library code. You could replace the message texts (for instance, with +messages in French or German) by changing the message table pointer. See +jerror.h for the default texts. CAUTION: this table will almost certainly +change or grow from one library version to the next. + +It may be useful for an application to add its own message texts that are +handled by the same mechanism. The error handler supports a second "add-on" +message table for this purpose. To define an addon table, set the pointer +err->addon_message_table and the message numbers err->first_addon_message and +err->last_addon_message. If you number the addon messages beginning at 1000 +or so, you won't have to worry about conflicts with the library's built-in +messages. See the sample applications cjpeg/djpeg for an example of using +addon messages (the addon messages are defined in cderror.h). + +Actual invocation of the error handler is done via macros defined in jerror.h: + ERREXITn(...) for fatal errors + WARNMSn(...) for corrupt-data warnings + TRACEMSn(...) for trace and informational messages. +These macros store the message code and any additional parameters into the +error handler struct, then invoke the error_exit() or emit_message() method. +The variants of each macro are for varying numbers of additional parameters. +The additional parameters are inserted into the generated message using +standard printf() format codes. + +See jerror.h and jerror.c for further details. + + +Compressed data handling (source and destination managers) +---------------------------------------------------------- + +The JPEG compression library sends its compressed data to a "destination +manager" module. The default destination manager just writes the data to a +memory buffer or to a stdio stream, but you can provide your own manager to +do something else. Similarly, the decompression library calls a "source +manager" to obtain the compressed data; you can provide your own source +manager if you want the data to come from somewhere other than a memory +buffer or a stdio stream. + +In both cases, compressed data is processed a bufferload at a time: the +destination or source manager provides a work buffer, and the library invokes +the manager only when the buffer is filled or emptied. (You could define a +one-character buffer to force the manager to be invoked for each byte, but +that would be rather inefficient.) The buffer's size and location are +controlled by the manager, not by the library. For example, the memory +source manager just makes the buffer pointer and length point to the original +data in memory. In this case the buffer-reload procedure will be invoked +only if the decompressor ran off the end of the datastream, which would +indicate an erroneous datastream. + +The work buffer is defined as an array of datatype JOCTET, which is generally +"char" or "unsigned char". On a machine where char is not exactly 8 bits +wide, you must define JOCTET as a wider data type and then modify the data +source and destination modules to transcribe the work arrays into 8-bit units +on external storage. + +A data destination manager struct contains a pointer and count defining the +next byte to write in the work buffer and the remaining free space: + + JOCTET * next_output_byte; /* => next byte to write in buffer */ + size_t free_in_buffer; /* # of byte spaces remaining in buffer */ + +The library increments the pointer and decrements the count until the buffer +is filled. The manager's empty_output_buffer method must reset the pointer +and count. The manager is expected to remember the buffer's starting address +and total size in private fields not visible to the library. + +A data destination manager provides three methods: + +init_destination (j_compress_ptr cinfo) + Initialize destination. This is called by jpeg_start_compress() + before any data is actually written. It must initialize + next_output_byte and free_in_buffer. free_in_buffer must be + initialized to a positive value. + +empty_output_buffer (j_compress_ptr cinfo) + This is called whenever the buffer has filled (free_in_buffer + reaches zero). In typical applications, it should write out the + *entire* buffer (use the saved start address and buffer length; + ignore the current state of next_output_byte and free_in_buffer). + Then reset the pointer & count to the start of the buffer, and + return TRUE indicating that the buffer has been dumped. + free_in_buffer must be set to a positive value when TRUE is + returned. A FALSE return should only be used when I/O suspension is + desired (this operating mode is discussed in the next section). + +term_destination (j_compress_ptr cinfo) + Terminate destination --- called by jpeg_finish_compress() after all + data has been written. In most applications, this must flush any + data remaining in the buffer. Use either next_output_byte or + free_in_buffer to determine how much data is in the buffer. + +term_destination() is NOT called by jpeg_abort() or jpeg_destroy(). If you +want the destination manager to be cleaned up during an abort, you must do it +yourself. + +You will also need code to create a jpeg_destination_mgr struct, fill in its +method pointers, and insert a pointer to the struct into the "dest" field of +the JPEG compression object. This can be done in-line in your setup code if +you like, but it's probably cleaner to provide a separate routine similar to +the jpeg_stdio_dest() or jpeg_mem_dest() routines of the supplied destination +managers. + +Decompression source managers follow a parallel design, but with some +additional frammishes. The source manager struct contains a pointer and count +defining the next byte to read from the work buffer and the number of bytes +remaining: + + const JOCTET * next_input_byte; /* => next byte to read from buffer */ + size_t bytes_in_buffer; /* # of bytes remaining in buffer */ + +The library increments the pointer and decrements the count until the buffer +is emptied. The manager's fill_input_buffer method must reset the pointer and +count. In most applications, the manager must remember the buffer's starting +address and total size in private fields not visible to the library. + +A data source manager provides five methods: + +init_source (j_decompress_ptr cinfo) + Initialize source. This is called by jpeg_read_header() before any + data is actually read. Unlike init_destination(), it may leave + bytes_in_buffer set to 0 (in which case a fill_input_buffer() call + will occur immediately). + +fill_input_buffer (j_decompress_ptr cinfo) + This is called whenever bytes_in_buffer has reached zero and more + data is wanted. In typical applications, it should read fresh data + into the buffer (ignoring the current state of next_input_byte and + bytes_in_buffer), reset the pointer & count to the start of the + buffer, and return TRUE indicating that the buffer has been reloaded. + It is not necessary to fill the buffer entirely, only to obtain at + least one more byte. bytes_in_buffer MUST be set to a positive value + if TRUE is returned. A FALSE return should only be used when I/O + suspension is desired (this mode is discussed in the next section). + +skip_input_data (j_decompress_ptr cinfo, long num_bytes) + Skip num_bytes worth of data. The buffer pointer and count should + be advanced over num_bytes input bytes, refilling the buffer as + needed. This is used to skip over a potentially large amount of + uninteresting data (such as an APPn marker). In some applications + it may be possible to optimize away the reading of the skipped data, + but it's not clear that being smart is worth much trouble; large + skips are uncommon. bytes_in_buffer may be zero on return. + A zero or negative skip count should be treated as a no-op. + +resync_to_restart (j_decompress_ptr cinfo, int desired) + This routine is called only when the decompressor has failed to find + a restart (RSTn) marker where one is expected. Its mission is to + find a suitable point for resuming decompression. For most + applications, we recommend that you just use the default resync + procedure, jpeg_resync_to_restart(). However, if you are able to back + up in the input data stream, or if you have a-priori knowledge about + the likely location of restart markers, you may be able to do better. + Read the read_restart_marker() and jpeg_resync_to_restart() routines + in jdmarker.c if you think you'd like to implement your own resync + procedure. + +term_source (j_decompress_ptr cinfo) + Terminate source --- called by jpeg_finish_decompress() after all + data has been read. Often a no-op. + +For both fill_input_buffer() and skip_input_data(), there is no such thing +as an EOF return. If the end of the file has been reached, the routine has +a choice of exiting via ERREXIT() or inserting fake data into the buffer. +In most cases, generating a warning message and inserting a fake EOI marker +is the best course of action --- this will allow the decompressor to output +however much of the image is there. In pathological cases, the decompressor +may swallow the EOI and again demand data ... just keep feeding it fake EOIs. +jdatasrc.c illustrates the recommended error recovery behavior. + +term_source() is NOT called by jpeg_abort() or jpeg_destroy(). If you want +the source manager to be cleaned up during an abort, you must do it yourself. + +You will also need code to create a jpeg_source_mgr struct, fill in its method +pointers, and insert a pointer to the struct into the "src" field of the JPEG +decompression object. This can be done in-line in your setup code if you +like, but it's probably cleaner to provide a separate routine similar to the +jpeg_stdio_src() or jpeg_mem_src() routines of the supplied source managers. + +For more information, consult the memory and stdio source and destination +managers in jdatasrc.c and jdatadst.c. + + +I/O suspension +-------------- + +Some applications need to use the JPEG library as an incremental memory-to- +memory filter: when the compressed data buffer is filled or emptied, they want +control to return to the outer loop, rather than expecting that the buffer can +be emptied or reloaded within the data source/destination manager subroutine. +The library supports this need by providing an "I/O suspension" mode, which we +describe in this section. + +The I/O suspension mode is not a panacea: nothing is guaranteed about the +maximum amount of time spent in any one call to the library, so it will not +eliminate response-time problems in single-threaded applications. If you +need guaranteed response time, we suggest you "bite the bullet" and implement +a real multi-tasking capability. + +To use I/O suspension, cooperation is needed between the calling application +and the data source or destination manager; you will always need a custom +source/destination manager. (Please read the previous section if you haven't +already.) The basic idea is that the empty_output_buffer() or +fill_input_buffer() routine is a no-op, merely returning FALSE to indicate +that it has done nothing. Upon seeing this, the JPEG library suspends +operation and returns to its caller. The surrounding application is +responsible for emptying or refilling the work buffer before calling the +JPEG library again. + +Compression suspension: + +For compression suspension, use an empty_output_buffer() routine that returns +FALSE; typically it will not do anything else. This will cause the +compressor to return to the caller of jpeg_write_scanlines(), with the return +value indicating that not all the supplied scanlines have been accepted. +The application must make more room in the output buffer, adjust the output +buffer pointer/count appropriately, and then call jpeg_write_scanlines() +again, pointing to the first unconsumed scanline. + +When forced to suspend, the compressor will backtrack to a convenient stopping +point (usually the start of the current MCU); it will regenerate some output +data when restarted. Therefore, although empty_output_buffer() is only +called when the buffer is filled, you should NOT write out the entire buffer +after a suspension. Write only the data up to the current position of +next_output_byte/free_in_buffer. The data beyond that point will be +regenerated after resumption. + +Because of the backtracking behavior, a good-size output buffer is essential +for efficiency; you don't want the compressor to suspend often. (In fact, an +overly small buffer could lead to infinite looping, if a single MCU required +more data than would fit in the buffer.) We recommend a buffer of at least +several Kbytes. You may want to insert explicit code to ensure that you don't +call jpeg_write_scanlines() unless there is a reasonable amount of space in +the output buffer; in other words, flush the buffer before trying to compress +more data. + +The compressor does not allow suspension while it is trying to write JPEG +markers at the beginning and end of the file. This means that: + * At the beginning of a compression operation, there must be enough free + space in the output buffer to hold the header markers (typically 600 or + so bytes). The recommended buffer size is bigger than this anyway, so + this is not a problem as long as you start with an empty buffer. However, + this restriction might catch you if you insert large special markers, such + as a JFIF thumbnail image, without flushing the buffer afterwards. + * When you call jpeg_finish_compress(), there must be enough space in the + output buffer to emit any buffered data and the final EOI marker. In the + current implementation, half a dozen bytes should suffice for this, but + for safety's sake we recommend ensuring that at least 100 bytes are free + before calling jpeg_finish_compress(). + +A more significant restriction is that jpeg_finish_compress() cannot suspend. +This means you cannot use suspension with multi-pass operating modes, namely +Huffman code optimization and multiple-scan output. Those modes write the +whole file during jpeg_finish_compress(), which will certainly result in +buffer overrun. (Note that this restriction applies only to compression, +not decompression. The decompressor supports input suspension in all of its +operating modes.) + +Decompression suspension: + +For decompression suspension, use a fill_input_buffer() routine that simply +returns FALSE (except perhaps during error recovery, as discussed below). +This will cause the decompressor to return to its caller with an indication +that suspension has occurred. This can happen at four places: + * jpeg_read_header(): will return JPEG_SUSPENDED. + * jpeg_start_decompress(): will return FALSE, rather than its usual TRUE. + * jpeg_read_scanlines(): will return the number of scanlines already + completed (possibly 0). + * jpeg_finish_decompress(): will return FALSE, rather than its usual TRUE. +The surrounding application must recognize these cases, load more data into +the input buffer, and repeat the call. In the case of jpeg_read_scanlines(), +increment the passed pointers past any scanlines successfully read. + +Just as with compression, the decompressor will typically backtrack to a +convenient restart point before suspending. When fill_input_buffer() is +called, next_input_byte/bytes_in_buffer point to the current restart point, +which is where the decompressor will backtrack to if FALSE is returned. +The data beyond that position must NOT be discarded if you suspend; it needs +to be re-read upon resumption. In most implementations, you'll need to shift +this data down to the start of your work buffer and then load more data after +it. Again, this behavior means that a several-Kbyte work buffer is essential +for decent performance; furthermore, you should load a reasonable amount of +new data before resuming decompression. (If you loaded, say, only one new +byte each time around, you could waste a LOT of cycles.) + +The skip_input_data() source manager routine requires special care in a +suspension scenario. This routine is NOT granted the ability to suspend the +decompressor; it can decrement bytes_in_buffer to zero, but no more. If the +requested skip distance exceeds the amount of data currently in the input +buffer, then skip_input_data() must set bytes_in_buffer to zero and record the +additional skip distance somewhere else. The decompressor will immediately +call fill_input_buffer(), which should return FALSE, which will cause a +suspension return. The surrounding application must then arrange to discard +the recorded number of bytes before it resumes loading the input buffer. +(Yes, this design is rather baroque, but it avoids complexity in the far more +common case where a non-suspending source manager is used.) + +If the input data has been exhausted, we recommend that you emit a warning +and insert dummy EOI markers just as a non-suspending data source manager +would do. This can be handled either in the surrounding application logic or +within fill_input_buffer(); the latter is probably more efficient. If +fill_input_buffer() knows that no more data is available, it can set the +pointer/count to point to a dummy EOI marker and then return TRUE just as +though it had read more data in a non-suspending situation. + +The decompressor does not attempt to suspend within standard JPEG markers; +instead it will backtrack to the start of the marker and reprocess the whole +marker next time. Hence the input buffer must be large enough to hold the +longest standard marker in the file. Standard JPEG markers should normally +not exceed a few hundred bytes each (DHT tables are typically the longest). +We recommend at least a 2K buffer for performance reasons, which is much +larger than any correct marker is likely to be. For robustness against +damaged marker length counts, you may wish to insert a test in your +application for the case that the input buffer is completely full and yet +the decoder has suspended without consuming any data --- otherwise, if this +situation did occur, it would lead to an endless loop. (The library can't +provide this test since it has no idea whether "the buffer is full", or +even whether there is a fixed-size input buffer.) + +The input buffer would need to be 64K to allow for arbitrary COM or APPn +markers, but these are handled specially: they are either saved into allocated +memory, or skipped over by calling skip_input_data(). In the former case, +suspension is handled correctly, and in the latter case, the problem of +buffer overrun is placed on skip_input_data's shoulders, as explained above. +Note that if you provide your own marker handling routine for large markers, +you should consider how to deal with buffer overflow. + +Multiple-buffer management: + +In some applications it is desirable to store the compressed data in a linked +list of buffer areas, so as to avoid data copying. This can be handled by +having empty_output_buffer() or fill_input_buffer() set the pointer and count +to reference the next available buffer; FALSE is returned only if no more +buffers are available. Although seemingly straightforward, there is a +pitfall in this approach: the backtrack that occurs when FALSE is returned +could back up into an earlier buffer. For example, when fill_input_buffer() +is called, the current pointer & count indicate the backtrack restart point. +Since fill_input_buffer() will set the pointer and count to refer to a new +buffer, the restart position must be saved somewhere else. Suppose a second +call to fill_input_buffer() occurs in the same library call, and no +additional input data is available, so fill_input_buffer must return FALSE. +If the JPEG library has not moved the pointer/count forward in the current +buffer, then *the correct restart point is the saved position in the prior +buffer*. Prior buffers may be discarded only after the library establishes +a restart point within a later buffer. Similar remarks apply for output into +a chain of buffers. + +The library will never attempt to backtrack over a skip_input_data() call, +so any skipped data can be permanently discarded. You still have to deal +with the case of skipping not-yet-received data, however. + +It's much simpler to use only a single buffer; when fill_input_buffer() is +called, move any unconsumed data (beyond the current pointer/count) down to +the beginning of this buffer and then load new data into the remaining buffer +space. This approach requires a little more data copying but is far easier +to get right. + + +Progressive JPEG support +------------------------ + +Progressive JPEG rearranges the stored data into a series of scans of +increasing quality. In situations where a JPEG file is transmitted across a +slow communications link, a decoder can generate a low-quality image very +quickly from the first scan, then gradually improve the displayed quality as +more scans are received. The final image after all scans are complete is +identical to that of a regular (sequential) JPEG file of the same quality +setting. Progressive JPEG files are often slightly smaller than equivalent +sequential JPEG files, but the possibility of incremental display is the main +reason for using progressive JPEG. + +The IJG encoder library generates progressive JPEG files when given a +suitable "scan script" defining how to divide the data into scans. +Creation of progressive JPEG files is otherwise transparent to the encoder. +Progressive JPEG files can also be read transparently by the decoder library. +If the decoding application simply uses the library as defined above, it +will receive a final decoded image without any indication that the file was +progressive. Of course, this approach does not allow incremental display. +To perform incremental display, an application needs to use the decoder +library's "buffered-image" mode, in which it receives a decoded image +multiple times. + +Each displayed scan requires about as much work to decode as a full JPEG +image of the same size, so the decoder must be fairly fast in relation to the +data transmission rate in order to make incremental display useful. However, +it is possible to skip displaying the image and simply add the incoming bits +to the decoder's coefficient buffer. This is fast because only Huffman +decoding need be done, not IDCT, upsampling, colorspace conversion, etc. +The IJG decoder library allows the application to switch dynamically between +displaying the image and simply absorbing the incoming bits. A properly +coded application can automatically adapt the number of display passes to +suit the time available as the image is received. Also, a final +higher-quality display cycle can be performed from the buffered data after +the end of the file is reached. + +Progressive compression: + +To create a progressive JPEG file (or a multiple-scan sequential JPEG file), +set the scan_info cinfo field to point to an array of scan descriptors, and +perform compression as usual. Instead of constructing your own scan list, +you can call the jpeg_simple_progression() helper routine to create a +recommended progression sequence; this method should be used by all +applications that don't want to get involved in the nitty-gritty of +progressive scan sequence design. (If you want to provide user control of +scan sequences, you may wish to borrow the scan script reading code found +in rdswitch.c, so that you can read scan script files just like cjpeg's.) +When scan_info is not NULL, the compression library will store DCT'd data +into a buffer array as jpeg_write_scanlines() is called, and will emit all +the requested scans during jpeg_finish_compress(). This implies that +multiple-scan output cannot be created with a suspending data destination +manager, since jpeg_finish_compress() does not support suspension. We +should also note that the compressor currently forces Huffman optimization +mode when creating a progressive JPEG file, because the default Huffman +tables are unsuitable for progressive files. + +Progressive decompression: + +When buffered-image mode is not used, the decoder library will read all of +a multi-scan file during jpeg_start_decompress(), so that it can provide a +final decoded image. (Here "multi-scan" means either progressive or +multi-scan sequential.) This makes multi-scan files transparent to the +decoding application. However, existing applications that used suspending +input with version 5 of the IJG library will need to be modified to check +for a suspension return from jpeg_start_decompress(). + +To perform incremental display, an application must use the library's +buffered-image mode. This is described in the next section. + + +Buffered-image mode +------------------- + +In buffered-image mode, the library stores the partially decoded image in a +coefficient buffer, from which it can be read out as many times as desired. +This mode is typically used for incremental display of progressive JPEG files, +but it can be used with any JPEG file. Each scan of a progressive JPEG file +adds more data (more detail) to the buffered image. The application can +display in lockstep with the source file (one display pass per input scan), +or it can allow input processing to outrun display processing. By making +input and display processing run independently, it is possible for the +application to adapt progressive display to a wide range of data transmission +rates. + +The basic control flow for buffered-image decoding is + + jpeg_create_decompress() + set data source + jpeg_read_header() + set overall decompression parameters + cinfo.buffered_image = TRUE; /* select buffered-image mode */ + jpeg_start_decompress() + for (each output pass) { + adjust output decompression parameters if required + jpeg_start_output() /* start a new output pass */ + for (all scanlines in image) { + jpeg_read_scanlines() + display scanlines + } + jpeg_finish_output() /* terminate output pass */ + } + jpeg_finish_decompress() + jpeg_destroy_decompress() + +This differs from ordinary unbuffered decoding in that there is an additional +level of looping. The application can choose how many output passes to make +and how to display each pass. + +The simplest approach to displaying progressive images is to do one display +pass for each scan appearing in the input file. In this case the outer loop +condition is typically + while (! jpeg_input_complete(&cinfo)) +and the start-output call should read + jpeg_start_output(&cinfo, cinfo.input_scan_number); +The second parameter to jpeg_start_output() indicates which scan of the input +file is to be displayed; the scans are numbered starting at 1 for this +purpose. (You can use a loop counter starting at 1 if you like, but using +the library's input scan counter is easier.) The library automatically reads +data as necessary to complete each requested scan, and jpeg_finish_output() +advances to the next scan or end-of-image marker (hence input_scan_number +will be incremented by the time control arrives back at jpeg_start_output()). +With this technique, data is read from the input file only as needed, and +input and output processing run in lockstep. + +After reading the final scan and reaching the end of the input file, the +buffered image remains available; it can be read additional times by +repeating the jpeg_start_output()/jpeg_read_scanlines()/jpeg_finish_output() +sequence. For example, a useful technique is to use fast one-pass color +quantization for display passes made while the image is arriving, followed by +a final display pass using two-pass quantization for highest quality. This +is done by changing the library parameters before the final output pass. +Changing parameters between passes is discussed in detail below. + +In general the last scan of a progressive file cannot be recognized as such +until after it is read, so a post-input display pass is the best approach if +you want special processing in the final pass. + +When done with the image, be sure to call jpeg_finish_decompress() to release +the buffered image (or just use jpeg_destroy_decompress()). + +If input data arrives faster than it can be displayed, the application can +cause the library to decode input data in advance of what's needed to produce +output. This is done by calling the routine jpeg_consume_input(). +The return value is one of the following: + JPEG_REACHED_SOS: reached an SOS marker (the start of a new scan) + JPEG_REACHED_EOI: reached the EOI marker (end of image) + JPEG_ROW_COMPLETED: completed reading one MCU row of compressed data + JPEG_SCAN_COMPLETED: completed reading last MCU row of current scan + JPEG_SUSPENDED: suspended before completing any of the above +(JPEG_SUSPENDED can occur only if a suspending data source is used.) This +routine can be called at any time after initializing the JPEG object. It +reads some additional data and returns when one of the indicated significant +events occurs. (If called after the EOI marker is reached, it will +immediately return JPEG_REACHED_EOI without attempting to read more data.) + +The library's output processing will automatically call jpeg_consume_input() +whenever the output processing overtakes the input; thus, simple lockstep +display requires no direct calls to jpeg_consume_input(). But by adding +calls to jpeg_consume_input(), you can absorb data in advance of what is +being displayed. This has two benefits: + * You can limit buildup of unprocessed data in your input buffer. + * You can eliminate extra display passes by paying attention to the + state of the library's input processing. + +The first of these benefits only requires interspersing calls to +jpeg_consume_input() with your display operations and any other processing +you may be doing. To avoid wasting cycles due to backtracking, it's best to +call jpeg_consume_input() only after a hundred or so new bytes have arrived. +This is discussed further under "I/O suspension", above. (Note: the JPEG +library currently is not thread-safe. You must not call jpeg_consume_input() +from one thread of control if a different library routine is working on the +same JPEG object in another thread.) + +When input arrives fast enough that more than one new scan is available +before you start a new output pass, you may as well skip the output pass +corresponding to the completed scan. This occurs for free if you pass +cinfo.input_scan_number as the target scan number to jpeg_start_output(). +The input_scan_number field is simply the index of the scan currently being +consumed by the input processor. You can ensure that this is up-to-date by +emptying the input buffer just before calling jpeg_start_output(): call +jpeg_consume_input() repeatedly until it returns JPEG_SUSPENDED or +JPEG_REACHED_EOI. + +The target scan number passed to jpeg_start_output() is saved in the +cinfo.output_scan_number field. The library's output processing calls +jpeg_consume_input() whenever the current input scan number and row within +that scan is less than or equal to the current output scan number and row. +Thus, input processing can "get ahead" of the output processing but is not +allowed to "fall behind". You can achieve several different effects by +manipulating this interlock rule. For example, if you pass a target scan +number greater than the current input scan number, the output processor will +wait until that scan starts to arrive before producing any output. (To avoid +an infinite loop, the target scan number is automatically reset to the last +scan number when the end of image is reached. Thus, if you specify a large +target scan number, the library will just absorb the entire input file and +then perform an output pass. This is effectively the same as what +jpeg_start_decompress() does when you don't select buffered-image mode.) +When you pass a target scan number equal to the current input scan number, +the image is displayed no faster than the current input scan arrives. The +final possibility is to pass a target scan number less than the current input +scan number; this disables the input/output interlock and causes the output +processor to simply display whatever it finds in the image buffer, without +waiting for input. (However, the library will not accept a target scan +number less than one, so you can't avoid waiting for the first scan.) + +When data is arriving faster than the output display processing can advance +through the image, jpeg_consume_input() will store data into the buffered +image beyond the point at which the output processing is reading data out +again. If the input arrives fast enough, it may "wrap around" the buffer to +the point where the input is more than one whole scan ahead of the output. +If the output processing simply proceeds through its display pass without +paying attention to the input, the effect seen on-screen is that the lower +part of the image is one or more scans better in quality than the upper part. +Then, when the next output scan is started, you have a choice of what target +scan number to use. The recommended choice is to use the current input scan +number at that time, which implies that you've skipped the output scans +corresponding to the input scans that were completed while you processed the +previous output scan. In this way, the decoder automatically adapts its +speed to the arriving data, by skipping output scans as necessary to keep up +with the arriving data. + +When using this strategy, you'll want to be sure that you perform a final +output pass after receiving all the data; otherwise your last display may not +be full quality across the whole screen. So the right outer loop logic is +something like this: + do { + absorb any waiting input by calling jpeg_consume_input() + final_pass = jpeg_input_complete(&cinfo); + adjust output decompression parameters if required + jpeg_start_output(&cinfo, cinfo.input_scan_number); + ... + jpeg_finish_output() + } while (! final_pass); +rather than quitting as soon as jpeg_input_complete() returns TRUE. This +arrangement makes it simple to use higher-quality decoding parameters +for the final pass. But if you don't want to use special parameters for +the final pass, the right loop logic is like this: + for (;;) { + absorb any waiting input by calling jpeg_consume_input() + jpeg_start_output(&cinfo, cinfo.input_scan_number); + ... + jpeg_finish_output() + if (jpeg_input_complete(&cinfo) && + cinfo.input_scan_number == cinfo.output_scan_number) + break; + } +In this case you don't need to know in advance whether an output pass is to +be the last one, so it's not necessary to have reached EOF before starting +the final output pass; rather, what you want to test is whether the output +pass was performed in sync with the final input scan. This form of the loop +will avoid an extra output pass whenever the decoder is able (or nearly able) +to keep up with the incoming data. + +When the data transmission speed is high, you might begin a display pass, +then find that much or all of the file has arrived before you can complete +the pass. (You can detect this by noting the JPEG_REACHED_EOI return code +from jpeg_consume_input(), or equivalently by testing jpeg_input_complete().) +In this situation you may wish to abort the current display pass and start a +new one using the newly arrived information. To do so, just call +jpeg_finish_output() and then start a new pass with jpeg_start_output(). + +A variant strategy is to abort and restart display if more than one complete +scan arrives during an output pass; this can be detected by noting +JPEG_REACHED_SOS returns and/or examining cinfo.input_scan_number. This +idea should be employed with caution, however, since the display process +might never get to the bottom of the image before being aborted, resulting +in the lower part of the screen being several passes worse than the upper. +In most cases it's probably best to abort an output pass only if the whole +file has arrived and you want to begin the final output pass immediately. + +When receiving data across a communication link, we recommend always using +the current input scan number for the output target scan number; if a +higher-quality final pass is to be done, it should be started (aborting any +incomplete output pass) as soon as the end of file is received. However, +many other strategies are possible. For example, the application can examine +the parameters of the current input scan and decide whether to display it or +not. If the scan contains only chroma data, one might choose not to use it +as the target scan, expecting that the scan will be small and will arrive +quickly. To skip to the next scan, call jpeg_consume_input() until it +returns JPEG_REACHED_SOS or JPEG_REACHED_EOI. Or just use the next higher +number as the target scan for jpeg_start_output(); but that method doesn't +let you inspect the next scan's parameters before deciding to display it. + + +In buffered-image mode, jpeg_start_decompress() never performs input and +thus never suspends. An application that uses input suspension with +buffered-image mode must be prepared for suspension returns from these +routines: +* jpeg_start_output() performs input only if you request 2-pass quantization + and the target scan isn't fully read yet. (This is discussed below.) +* jpeg_read_scanlines(), as always, returns the number of scanlines that it + was able to produce before suspending. +* jpeg_finish_output() will read any markers following the target scan, + up to the end of the file or the SOS marker that begins another scan. + (But it reads no input if jpeg_consume_input() has already reached the + end of the file or a SOS marker beyond the target output scan.) +* jpeg_finish_decompress() will read until the end of file, and thus can + suspend if the end hasn't already been reached (as can be tested by + calling jpeg_input_complete()). +jpeg_start_output(), jpeg_finish_output(), and jpeg_finish_decompress() +all return TRUE if they completed their tasks, FALSE if they had to suspend. +In the event of a FALSE return, the application must load more input data +and repeat the call. Applications that use non-suspending data sources need +not check the return values of these three routines. + + +It is possible to change decoding parameters between output passes in the +buffered-image mode. The decoder library currently supports only very +limited changes of parameters. ONLY THE FOLLOWING parameter changes are +allowed after jpeg_start_decompress() is called: +* dct_method can be changed before each call to jpeg_start_output(). + For example, one could use a fast DCT method for early scans, changing + to a higher quality method for the final scan. +* dither_mode can be changed before each call to jpeg_start_output(); + of course this has no impact if not using color quantization. Typically + one would use ordered dither for initial passes, then switch to + Floyd-Steinberg dither for the final pass. Caution: changing dither mode + can cause more memory to be allocated by the library. Although the amount + of memory involved is not large (a scanline or so), it may cause the + initial max_memory_to_use specification to be exceeded, which in the worst + case would result in an out-of-memory failure. +* do_block_smoothing can be changed before each call to jpeg_start_output(). + This setting is relevant only when decoding a progressive JPEG image. + During the first DC-only scan, block smoothing provides a very "fuzzy" look + instead of the very "blocky" look seen without it; which is better seems a + matter of personal taste. But block smoothing is nearly always a win + during later stages, especially when decoding a successive-approximation + image: smoothing helps to hide the slight blockiness that otherwise shows + up on smooth gradients until the lowest coefficient bits are sent. +* Color quantization mode can be changed under the rules described below. + You *cannot* change between full-color and quantized output (because that + would alter the required I/O buffer sizes), but you can change which + quantization method is used. + +When generating color-quantized output, changing quantization method is a +very useful way of switching between high-speed and high-quality display. +The library allows you to change among its three quantization methods: +1. Single-pass quantization to a fixed color cube. + Selected by cinfo.two_pass_quantize = FALSE and cinfo.colormap = NULL. +2. Single-pass quantization to an application-supplied colormap. + Selected by setting cinfo.colormap to point to the colormap (the value of + two_pass_quantize is ignored); also set cinfo.actual_number_of_colors. +3. Two-pass quantization to a colormap chosen specifically for the image. + Selected by cinfo.two_pass_quantize = TRUE and cinfo.colormap = NULL. + (This is the default setting selected by jpeg_read_header, but it is + probably NOT what you want for the first pass of progressive display!) +These methods offer successively better quality and lesser speed. However, +only the first method is available for quantizing in non-RGB color spaces. + +IMPORTANT: because the different quantizer methods have very different +working-storage requirements, the library requires you to indicate which +one(s) you intend to use before you call jpeg_start_decompress(). (If we did +not require this, the max_memory_to_use setting would be a complete fiction.) +You do this by setting one or more of these three cinfo fields to TRUE: + enable_1pass_quant Fixed color cube colormap + enable_external_quant Externally-supplied colormap + enable_2pass_quant Two-pass custom colormap +All three are initialized FALSE by jpeg_read_header(). But +jpeg_start_decompress() automatically sets TRUE the one selected by the +current two_pass_quantize and colormap settings, so you only need to set the +enable flags for any other quantization methods you plan to change to later. + +After setting the enable flags correctly at jpeg_start_decompress() time, you +can change to any enabled quantization method by setting two_pass_quantize +and colormap properly just before calling jpeg_start_output(). The following +special rules apply: +1. You must explicitly set cinfo.colormap to NULL when switching to 1-pass + or 2-pass mode from a different mode, or when you want the 2-pass + quantizer to be re-run to generate a new colormap. +2. To switch to an external colormap, or to change to a different external + colormap than was used on the prior pass, you must call + jpeg_new_colormap() after setting cinfo.colormap. +NOTE: if you want to use the same colormap as was used in the prior pass, +you should not do either of these things. This will save some nontrivial +switchover costs. +(These requirements exist because cinfo.colormap will always be non-NULL +after completing a prior output pass, since both the 1-pass and 2-pass +quantizers set it to point to their output colormaps. Thus you have to +do one of these two things to notify the library that something has changed. +Yup, it's a bit klugy, but it's necessary to do it this way for backwards +compatibility.) + +Note that in buffered-image mode, the library generates any requested colormap +during jpeg_start_output(), not during jpeg_start_decompress(). + +When using two-pass quantization, jpeg_start_output() makes a pass over the +buffered image to determine the optimum color map; it therefore may take a +significant amount of time, whereas ordinarily it does little work. The +progress monitor hook is called during this pass, if defined. It is also +important to realize that if the specified target scan number is greater than +or equal to the current input scan number, jpeg_start_output() will attempt +to consume input as it makes this pass. If you use a suspending data source, +you need to check for a FALSE return from jpeg_start_output() under these +conditions. The combination of 2-pass quantization and a not-yet-fully-read +target scan is the only case in which jpeg_start_output() will consume input. + + +Application authors who support buffered-image mode may be tempted to use it +for all JPEG images, even single-scan ones. This will work, but it is +inefficient: there is no need to create an image-sized coefficient buffer for +single-scan images. Requesting buffered-image mode for such an image wastes +memory. Worse, it can cost time on large images, since the buffered data has +to be swapped out or written to a temporary file. If you are concerned about +maximum performance on baseline JPEG files, you should use buffered-image +mode only when the incoming file actually has multiple scans. This can be +tested by calling jpeg_has_multiple_scans(), which will return a correct +result at any time after jpeg_read_header() completes. + +It is also worth noting that when you use jpeg_consume_input() to let input +processing get ahead of output processing, the resulting pattern of access to +the coefficient buffer is quite nonsequential. It's best to use the memory +manager jmemnobs.c if you can (ie, if you have enough real or virtual main +memory). If not, at least make sure that max_memory_to_use is set as high as +possible. If the JPEG memory manager has to use a temporary file, you will +probably see a lot of disk traffic and poor performance. (This could be +improved with additional work on the memory manager, but we haven't gotten +around to it yet.) + +In some applications it may be convenient to use jpeg_consume_input() for all +input processing, including reading the initial markers; that is, you may +wish to call jpeg_consume_input() instead of jpeg_read_header() during +startup. This works, but note that you must check for JPEG_REACHED_SOS and +JPEG_REACHED_EOI return codes as the equivalent of jpeg_read_header's codes. +Once the first SOS marker has been reached, you must call +jpeg_start_decompress() before jpeg_consume_input() will consume more input; +it'll just keep returning JPEG_REACHED_SOS until you do. If you read a +tables-only file this way, jpeg_consume_input() will return JPEG_REACHED_EOI +without ever returning JPEG_REACHED_SOS; be sure to check for this case. +If this happens, the decompressor will not read any more input until you call +jpeg_abort() to reset it. It is OK to call jpeg_consume_input() even when not +using buffered-image mode, but in that case it's basically a no-op after the +initial markers have been read: it will just return JPEG_SUSPENDED. + + +Abbreviated datastreams and multiple images +------------------------------------------- + +A JPEG compression or decompression object can be reused to process multiple +images. This saves a small amount of time per image by eliminating the +"create" and "destroy" operations, but that isn't the real purpose of the +feature. Rather, reuse of an object provides support for abbreviated JPEG +datastreams. Object reuse can also simplify processing a series of images in +a single input or output file. This section explains these features. + +A JPEG file normally contains several hundred bytes worth of quantization +and Huffman tables. In a situation where many images will be stored or +transmitted with identical tables, this may represent an annoying overhead. +The JPEG standard therefore permits tables to be omitted. The standard +defines three classes of JPEG datastreams: + * "Interchange" datastreams contain an image and all tables needed to decode + the image. These are the usual kind of JPEG file. + * "Abbreviated image" datastreams contain an image, but are missing some or + all of the tables needed to decode that image. + * "Abbreviated table specification" (henceforth "tables-only") datastreams + contain only table specifications. +To decode an abbreviated image, it is necessary to load the missing table(s) +into the decoder beforehand. This can be accomplished by reading a separate +tables-only file. A variant scheme uses a series of images in which the first +image is an interchange (complete) datastream, while subsequent ones are +abbreviated and rely on the tables loaded by the first image. It is assumed +that once the decoder has read a table, it will remember that table until a +new definition for the same table number is encountered. + +It is the application designer's responsibility to figure out how to associate +the correct tables with an abbreviated image. While abbreviated datastreams +can be useful in a closed environment, their use is strongly discouraged in +any situation where data exchange with other applications might be needed. +Caveat designer. + +The JPEG library provides support for reading and writing any combination of +tables-only datastreams and abbreviated images. In both compression and +decompression objects, a quantization or Huffman table will be retained for +the lifetime of the object, unless it is overwritten by a new table definition. + + +To create abbreviated image datastreams, it is only necessary to tell the +compressor not to emit some or all of the tables it is using. Each +quantization and Huffman table struct contains a boolean field "sent_table", +which normally is initialized to FALSE. For each table used by the image, the +header-writing process emits the table and sets sent_table = TRUE unless it is +already TRUE. (In normal usage, this prevents outputting the same table +definition multiple times, as would otherwise occur because the chroma +components typically share tables.) Thus, setting this field to TRUE before +calling jpeg_start_compress() will prevent the table from being written at +all. + +If you want to create a "pure" abbreviated image file containing no tables, +just call "jpeg_suppress_tables(&cinfo, TRUE)" after constructing all the +tables. If you want to emit some but not all tables, you'll need to set the +individual sent_table fields directly. + +To create an abbreviated image, you must also call jpeg_start_compress() +with a second parameter of FALSE, not TRUE. Otherwise jpeg_start_compress() +will force all the sent_table fields to FALSE. (This is a safety feature to +prevent abbreviated images from being created accidentally.) + +To create a tables-only file, perform the same parameter setup that you +normally would, but instead of calling jpeg_start_compress() and so on, call +jpeg_write_tables(&cinfo). This will write an abbreviated datastream +containing only SOI, DQT and/or DHT markers, and EOI. All the quantization +and Huffman tables that are currently defined in the compression object will +be emitted unless their sent_tables flag is already TRUE, and then all the +sent_tables flags will be set TRUE. + +A sure-fire way to create matching tables-only and abbreviated image files +is to proceed as follows: + + create JPEG compression object + set JPEG parameters + set destination to tables-only file + jpeg_write_tables(&cinfo); + set destination to image file + jpeg_start_compress(&cinfo, FALSE); + write data... + jpeg_finish_compress(&cinfo); + +Since the JPEG parameters are not altered between writing the table file and +the abbreviated image file, the same tables are sure to be used. Of course, +you can repeat the jpeg_start_compress() ... jpeg_finish_compress() sequence +many times to produce many abbreviated image files matching the table file. + +You cannot suppress output of the computed Huffman tables when Huffman +optimization is selected. (If you could, there'd be no way to decode the +image...) Generally, you don't want to set optimize_coding = TRUE when +you are trying to produce abbreviated files. + +In some cases you might want to compress an image using tables which are +not stored in the application, but are defined in an interchange or +tables-only file readable by the application. This can be done by setting up +a JPEG decompression object to read the specification file, then copying the +tables into your compression object. See jpeg_copy_critical_parameters() +for an example of copying quantization tables. + + +To read abbreviated image files, you simply need to load the proper tables +into the decompression object before trying to read the abbreviated image. +If the proper tables are stored in the application program, you can just +allocate the table structs and fill in their contents directly. For example, +to load a fixed quantization table into table slot "n": + + if (cinfo.quant_tbl_ptrs[n] == NULL) + cinfo.quant_tbl_ptrs[n] = jpeg_alloc_quant_table((j_common_ptr) &cinfo); + quant_ptr = cinfo.quant_tbl_ptrs[n]; /* quant_ptr is JQUANT_TBL* */ + for (i = 0; i < 64; i++) { + /* Qtable[] is desired quantization table, in natural array order */ + quant_ptr->quantval[i] = Qtable[i]; + } + +Code to load a fixed Huffman table is typically (for AC table "n"): + + if (cinfo.ac_huff_tbl_ptrs[n] == NULL) + cinfo.ac_huff_tbl_ptrs[n] = jpeg_alloc_huff_table((j_common_ptr) &cinfo); + huff_ptr = cinfo.ac_huff_tbl_ptrs[n]; /* huff_ptr is JHUFF_TBL* */ + for (i = 1; i <= 16; i++) { + /* counts[i] is number of Huffman codes of length i bits, i=1..16 */ + huff_ptr->bits[i] = counts[i]; + } + for (i = 0; i < 256; i++) { + /* symbols[] is the list of Huffman symbols, in code-length order */ + huff_ptr->huffval[i] = symbols[i]; + } + +(Note that trying to set cinfo.quant_tbl_ptrs[n] to point directly at a +constant JQUANT_TBL object is not safe. If the incoming file happened to +contain a quantization table definition, your master table would get +overwritten! Instead allocate a working table copy and copy the master table +into it, as illustrated above. Ditto for Huffman tables, of course.) + +You might want to read the tables from a tables-only file, rather than +hard-wiring them into your application. The jpeg_read_header() call is +sufficient to read a tables-only file. You must pass a second parameter of +FALSE to indicate that you do not require an image to be present. Thus, the +typical scenario is + + create JPEG decompression object + set source to tables-only file + jpeg_read_header(&cinfo, FALSE); + set source to abbreviated image file + jpeg_read_header(&cinfo, TRUE); + set decompression parameters + jpeg_start_decompress(&cinfo); + read data... + jpeg_finish_decompress(&cinfo); + +In some cases, you may want to read a file without knowing whether it contains +an image or just tables. In that case, pass FALSE and check the return value +from jpeg_read_header(): it will be JPEG_HEADER_OK if an image was found, +JPEG_HEADER_TABLES_ONLY if only tables were found. (A third return value, +JPEG_SUSPENDED, is possible when using a suspending data source manager.) +Note that jpeg_read_header() will not complain if you read an abbreviated +image for which you haven't loaded the missing tables; the missing-table check +occurs later, in jpeg_start_decompress(). + + +It is possible to read a series of images from a single source file by +repeating the jpeg_read_header() ... jpeg_finish_decompress() sequence, +without releasing/recreating the JPEG object or the data source module. +(If you did reinitialize, any partial bufferload left in the data source +buffer at the end of one image would be discarded, causing you to lose the +start of the next image.) When you use this method, stored tables are +automatically carried forward, so some of the images can be abbreviated images +that depend on tables from earlier images. + +If you intend to write a series of images into a single destination file, +you might want to make a specialized data destination module that doesn't +flush the output buffer at term_destination() time. This would speed things +up by some trifling amount. Of course, you'd need to remember to flush the +buffer after the last image. You can make the later images be abbreviated +ones by passing FALSE to jpeg_start_compress(). + + +Special markers +--------------- + +Some applications may need to insert or extract special data in the JPEG +datastream. The JPEG standard provides marker types "COM" (comment) and +"APP0" through "APP15" (application) to hold application-specific data. +Unfortunately, the use of these markers is not specified by the standard. +COM markers are fairly widely used to hold user-supplied text. The JFIF file +format spec uses APP0 markers with specified initial strings to hold certain +data. Adobe applications use APP14 markers beginning with the string "Adobe" +for miscellaneous data. Other APPn markers are rarely seen, but might +contain almost anything. + +If you wish to store user-supplied text, we recommend you use COM markers +and place readable 7-bit ASCII text in them. Newline conventions are not +standardized --- expect to find LF (Unix style), CR/LF (DOS style), or CR +(Mac style). A robust COM reader should be able to cope with random binary +garbage, including nulls, since some applications generate COM markers +containing non-ASCII junk. (But yours should not be one of them.) + +For program-supplied data, use an APPn marker, and be sure to begin it with an +identifying string so that you can tell whether the marker is actually yours. +It's probably best to avoid using APP0 or APP14 for any private markers. +(NOTE: the upcoming SPIFF standard will use APP8 markers; we recommend you +not use APP8 markers for any private purposes, either.) + +Keep in mind that at most 65533 bytes can be put into one marker, but you +can have as many markers as you like. + +By default, the IJG compression library will write a JFIF APP0 marker if the +selected JPEG colorspace is grayscale or YCbCr, or an Adobe APP14 marker if +the selected colorspace is RGB, CMYK, or YCCK. You can disable this, but +we don't recommend it. The decompression library will recognize JFIF and +Adobe markers and will set the JPEG colorspace properly when one is found. + + +You can write special markers immediately following the datastream header by +calling jpeg_write_marker() after jpeg_start_compress() and before the first +call to jpeg_write_scanlines(). When you do this, the markers appear after +the SOI and the JFIF APP0 and Adobe APP14 markers (if written), but before +all else. Specify the marker type parameter as "JPEG_COM" for COM or +"JPEG_APP0 + n" for APPn. (Actually, jpeg_write_marker will let you write +any marker type, but we don't recommend writing any other kinds of marker.) +For example, to write a user comment string pointed to by comment_text: + jpeg_write_marker(cinfo, JPEG_COM, comment_text, strlen(comment_text)); + +If it's not convenient to store all the marker data in memory at once, +you can instead call jpeg_write_m_header() followed by multiple calls to +jpeg_write_m_byte(). If you do it this way, it's your responsibility to +call jpeg_write_m_byte() exactly the number of times given in the length +parameter to jpeg_write_m_header(). (This method lets you empty the +output buffer partway through a marker, which might be important when +using a suspending data destination module. In any case, if you are using +a suspending destination, you should flush its buffer after inserting +any special markers. See "I/O suspension".) + +Or, if you prefer to synthesize the marker byte sequence yourself, +you can just cram it straight into the data destination module. + +If you are writing JFIF 1.02 extension markers (thumbnail images), don't +forget to set cinfo.JFIF_minor_version = 2 so that the encoder will write the +correct JFIF version number in the JFIF header marker. The library's default +is to write version 1.01, but that's wrong if you insert any 1.02 extension +markers. (We could probably get away with just defaulting to 1.02, but there +used to be broken decoders that would complain about unknown minor version +numbers. To reduce compatibility risks it's safest not to write 1.02 unless +you are actually using 1.02 extensions.) + + +When reading, two methods of handling special markers are available: +1. You can ask the library to save the contents of COM and/or APPn markers +into memory, and then examine them at your leisure afterwards. +2. You can supply your own routine to process COM and/or APPn markers +on-the-fly as they are read. +The first method is simpler to use, especially if you are using a suspending +data source; writing a marker processor that copes with input suspension is +not easy (consider what happens if the marker is longer than your available +input buffer). However, the second method conserves memory since the marker +data need not be kept around after it's been processed. + +For either method, you'd normally set up marker handling after creating a +decompression object and before calling jpeg_read_header(), because the +markers of interest will typically be near the head of the file and so will +be scanned by jpeg_read_header. Once you've established a marker handling +method, it will be used for the life of that decompression object +(potentially many datastreams), unless you change it. Marker handling is +determined separately for COM markers and for each APPn marker code. + + +To save the contents of special markers in memory, call + jpeg_save_markers(cinfo, marker_code, length_limit) +where marker_code is the marker type to save, JPEG_COM or JPEG_APP0+n. +(To arrange to save all the special marker types, you need to call this +routine 17 times, for COM and APP0-APP15.) If the incoming marker is longer +than length_limit data bytes, only length_limit bytes will be saved; this +parameter allows you to avoid chewing up memory when you only need to see the +first few bytes of a potentially large marker. If you want to save all the +data, set length_limit to 0xFFFF; that is enough since marker lengths are only +16 bits. As a special case, setting length_limit to 0 prevents that marker +type from being saved at all. (That is the default behavior, in fact.) + +After jpeg_read_header() completes, you can examine the special markers by +following the cinfo->marker_list pointer chain. All the special markers in +the file appear in this list, in order of their occurrence in the file (but +omitting any markers of types you didn't ask for). Both the original data +length and the saved data length are recorded for each list entry; the latter +will not exceed length_limit for the particular marker type. Note that these +lengths exclude the marker length word, whereas the stored representation +within the JPEG file includes it. (Hence the maximum data length is really +only 65533.) + +It is possible that additional special markers appear in the file beyond the +SOS marker at which jpeg_read_header stops; if so, the marker list will be +extended during reading of the rest of the file. This is not expected to be +common, however. If you are short on memory you may want to reset the length +limit to zero for all marker types after finishing jpeg_read_header, to +ensure that the max_memory_to_use setting cannot be exceeded due to addition +of later markers. + +The marker list remains stored until you call jpeg_finish_decompress or +jpeg_abort, at which point the memory is freed and the list is set to empty. +(jpeg_destroy also releases the storage, of course.) + +Note that the library is internally interested in APP0 and APP14 markers; +if you try to set a small nonzero length limit on these types, the library +will silently force the length up to the minimum it wants. (But you can set +a zero length limit to prevent them from being saved at all.) Also, in a +16-bit environment, the maximum length limit may be constrained to less than +65533 by malloc() limitations. It is therefore best not to assume that the +effective length limit is exactly what you set it to be. + + +If you want to supply your own marker-reading routine, you do it by calling +jpeg_set_marker_processor(). A marker processor routine must have the +signature + boolean jpeg_marker_parser_method (j_decompress_ptr cinfo) +Although the marker code is not explicitly passed, the routine can find it +in cinfo->unread_marker. At the time of call, the marker proper has been +read from the data source module. The processor routine is responsible for +reading the marker length word and the remaining parameter bytes, if any. +Return TRUE to indicate success. (FALSE should be returned only if you are +using a suspending data source and it tells you to suspend. See the standard +marker processors in jdmarker.c for appropriate coding methods if you need to +use a suspending data source.) + +If you override the default APP0 or APP14 processors, it is up to you to +recognize JFIF and Adobe markers if you want colorspace recognition to occur +properly. We recommend copying and extending the default processors if you +want to do that. (A better idea is to save these marker types for later +examination by calling jpeg_save_markers(); that method doesn't interfere +with the library's own processing of these markers.) + +jpeg_set_marker_processor() and jpeg_save_markers() are mutually exclusive +--- if you call one it overrides any previous call to the other, for the +particular marker type specified. + +A simple example of an external COM processor can be found in djpeg.c. +Also, see jpegtran.c for an example of using jpeg_save_markers. + + +Raw (downsampled) image data +---------------------------- + +Some applications need to supply already-downsampled image data to the JPEG +compressor, or to receive raw downsampled data from the decompressor. The +library supports this requirement by allowing the application to write or +read raw data, bypassing the normal preprocessing or postprocessing steps. +The interface is different from the standard one and is somewhat harder to +use. If your interest is merely in bypassing color conversion, we recommend +that you use the standard interface and simply set jpeg_color_space = +in_color_space (or jpeg_color_space = out_color_space for decompression). +The mechanism described in this section is necessary only to supply or +receive downsampled image data, in which not all components have the same +dimensions. + + +To compress raw data, you must supply the data in the colorspace to be used +in the JPEG file (please read the earlier section on Special color spaces) +and downsampled to the sampling factors specified in the JPEG parameters. +You must supply the data in the format used internally by the JPEG library, +namely a JSAMPIMAGE array. This is an array of pointers to two-dimensional +arrays, each of type JSAMPARRAY. Each 2-D array holds the values for one +color component. This structure is necessary since the components are of +different sizes. If the image dimensions are not a multiple of the MCU size, +you must also pad the data correctly (usually, this is done by replicating +the last column and/or row). The data must be padded to a multiple of a DCT +block in each component: that is, each downsampled row must contain a +multiple of block_size valid samples, and there must be a multiple of +block_size sample rows for each component. (For applications such as +conversion of digital TV images, the standard image size is usually a +multiple of the DCT block size, so that no padding need actually be done.) + +The procedure for compression of raw data is basically the same as normal +compression, except that you call jpeg_write_raw_data() in place of +jpeg_write_scanlines(). Before calling jpeg_start_compress(), you must do +the following: + * Set cinfo->raw_data_in to TRUE. (It is set FALSE by jpeg_set_defaults().) + This notifies the library that you will be supplying raw data. + Furthermore, set cinfo->do_fancy_downsampling to FALSE if you want to use + real downsampled data. (It is set TRUE by jpeg_set_defaults().) + * Ensure jpeg_color_space is correct --- an explicit jpeg_set_colorspace() + call is a good idea. Note that since color conversion is bypassed, + in_color_space is ignored, except that jpeg_set_defaults() uses it to + choose the default jpeg_color_space setting. + * Ensure the sampling factors, cinfo->comp_info[i].h_samp_factor and + cinfo->comp_info[i].v_samp_factor, are correct. Since these indicate the + dimensions of the data you are supplying, it's wise to set them + explicitly, rather than assuming the library's defaults are what you want. + +To pass raw data to the library, call jpeg_write_raw_data() in place of +jpeg_write_scanlines(). The two routines work similarly except that +jpeg_write_raw_data takes a JSAMPIMAGE data array rather than JSAMPARRAY. +The scanlines count passed to and returned from jpeg_write_raw_data is +measured in terms of the component with the largest v_samp_factor. + +jpeg_write_raw_data() processes one MCU row per call, which is to say +v_samp_factor*block_size sample rows of each component. The passed num_lines +value must be at least max_v_samp_factor*block_size, and the return value +will be exactly that amount (or possibly some multiple of that amount, in +future library versions). This is true even on the last call at the bottom +of the image; don't forget to pad your data as necessary. + +The required dimensions of the supplied data can be computed for each +component as + cinfo->comp_info[i].width_in_blocks*block_size samples per row + cinfo->comp_info[i].height_in_blocks*block_size rows in image +after jpeg_start_compress() has initialized those fields. If the valid data +is smaller than this, it must be padded appropriately. For some sampling +factors and image sizes, additional dummy DCT blocks are inserted to make +the image a multiple of the MCU dimensions. The library creates such dummy +blocks itself; it does not read them from your supplied data. Therefore you +need never pad by more than block_size samples. An example may help here. +Assume 2h2v downsampling of YCbCr data, that is + cinfo->comp_info[0].h_samp_factor = 2 for Y + cinfo->comp_info[0].v_samp_factor = 2 + cinfo->comp_info[1].h_samp_factor = 1 for Cb + cinfo->comp_info[1].v_samp_factor = 1 + cinfo->comp_info[2].h_samp_factor = 1 for Cr + cinfo->comp_info[2].v_samp_factor = 1 +and suppose that the nominal image dimensions (cinfo->image_width and +cinfo->image_height) are 101x101 pixels. Then jpeg_start_compress() will +compute downsampled_width = 101 and width_in_blocks = 13 for Y, +downsampled_width = 51 and width_in_blocks = 7 for Cb and Cr (and the same +for the height fields). You must pad the Y data to at least 13*8 = 104 +columns and rows, the Cb/Cr data to at least 7*8 = 56 columns and rows. The +MCU height is max_v_samp_factor = 2 DCT rows so you must pass at least 16 +scanlines on each call to jpeg_write_raw_data(), which is to say 16 actual +sample rows of Y and 8 each of Cb and Cr. A total of 7 MCU rows are needed, +so you must pass a total of 7*16 = 112 "scanlines". The last DCT block row +of Y data is dummy, so it doesn't matter what you pass for it in the data +arrays, but the scanlines count must total up to 112 so that all of the Cb +and Cr data gets passed. + +Output suspension is supported with raw-data compression: if the data +destination module suspends, jpeg_write_raw_data() will return 0. +In this case the same data rows must be passed again on the next call. + + +Decompression with raw data output implies bypassing all postprocessing. +You must deal with the color space and sampling factors present in the +incoming file. If your application only handles, say, 2h1v YCbCr data, +you must check for and fail on other color spaces or other sampling factors. +The library will not convert to a different color space for you. + +To obtain raw data output, set cinfo->raw_data_out = TRUE before +jpeg_start_decompress() (it is set FALSE by jpeg_read_header()). Be sure to +verify that the color space and sampling factors are ones you can handle. +Furthermore, set cinfo->do_fancy_upsampling = FALSE if you want to get real +downsampled data (it is set TRUE by jpeg_read_header()). +Then call jpeg_read_raw_data() in place of jpeg_read_scanlines(). The +decompression process is otherwise the same as usual. + +jpeg_read_raw_data() returns one MCU row per call, and thus you must pass a +buffer of at least max_v_samp_factor*block_size scanlines (scanline counting +is the same as for raw-data compression). The buffer you pass must be large +enough to hold the actual data plus padding to DCT-block boundaries. As with +compression, any entirely dummy DCT blocks are not processed so you need not +allocate space for them, but the total scanline count includes them. The +above example of computing buffer dimensions for raw-data compression is +equally valid for decompression. + +Input suspension is supported with raw-data decompression: if the data source +module suspends, jpeg_read_raw_data() will return 0. You can also use +buffered-image mode to read raw data in multiple passes. + + +Really raw data: DCT coefficients +--------------------------------- + +It is possible to read or write the contents of a JPEG file as raw DCT +coefficients. This facility is mainly intended for use in lossless +transcoding between different JPEG file formats. Other possible applications +include lossless cropping of a JPEG image, lossless reassembly of a +multi-strip or multi-tile TIFF/JPEG file into a single JPEG datastream, etc. + +To read the contents of a JPEG file as DCT coefficients, open the file and do +jpeg_read_header() as usual. But instead of calling jpeg_start_decompress() +and jpeg_read_scanlines(), call jpeg_read_coefficients(). This will read the +entire image into a set of virtual coefficient-block arrays, one array per +component. The return value is a pointer to an array of virtual-array +descriptors. Each virtual array can be accessed directly using the JPEG +memory manager's access_virt_barray method (see Memory management, below, +and also read structure.txt's discussion of virtual array handling). Or, +for simple transcoding to a different JPEG file format, the array list can +just be handed directly to jpeg_write_coefficients(). + +Each block in the block arrays contains quantized coefficient values in +normal array order (not JPEG zigzag order). The block arrays contain only +DCT blocks containing real data; any entirely-dummy blocks added to fill out +interleaved MCUs at the right or bottom edges of the image are discarded +during reading and are not stored in the block arrays. (The size of each +block array can be determined from the width_in_blocks and height_in_blocks +fields of the component's comp_info entry.) This is also the data format +expected by jpeg_write_coefficients(). + +When you are done using the virtual arrays, call jpeg_finish_decompress() +to release the array storage and return the decompression object to an idle +state; or just call jpeg_destroy() if you don't need to reuse the object. + +If you use a suspending data source, jpeg_read_coefficients() will return +NULL if it is forced to suspend; a non-NULL return value indicates successful +completion. You need not test for a NULL return value when using a +non-suspending data source. + +It is also possible to call jpeg_read_coefficients() to obtain access to the +decoder's coefficient arrays during a normal decode cycle in buffered-image +mode. This frammish might be useful for progressively displaying an incoming +image and then re-encoding it without loss. To do this, decode in buffered- +image mode as discussed previously, then call jpeg_read_coefficients() after +the last jpeg_finish_output() call. The arrays will be available for your use +until you call jpeg_finish_decompress(). + + +To write the contents of a JPEG file as DCT coefficients, you must provide +the DCT coefficients stored in virtual block arrays. You can either pass +block arrays read from an input JPEG file by jpeg_read_coefficients(), or +allocate virtual arrays from the JPEG compression object and fill them +yourself. In either case, jpeg_write_coefficients() is substituted for +jpeg_start_compress() and jpeg_write_scanlines(). Thus the sequence is + * Create compression object + * Set all compression parameters as necessary + * Request virtual arrays if needed + * jpeg_write_coefficients() + * jpeg_finish_compress() + * Destroy or re-use compression object +jpeg_write_coefficients() is passed a pointer to an array of virtual block +array descriptors; the number of arrays is equal to cinfo.num_components. + +The virtual arrays need only have been requested, not realized, before +jpeg_write_coefficients() is called. A side-effect of +jpeg_write_coefficients() is to realize any virtual arrays that have been +requested from the compression object's memory manager. Thus, when obtaining +the virtual arrays from the compression object, you should fill the arrays +after calling jpeg_write_coefficients(). The data is actually written out +when you call jpeg_finish_compress(); jpeg_write_coefficients() only writes +the file header. + +When writing raw DCT coefficients, it is crucial that the JPEG quantization +tables and sampling factors match the way the data was encoded, or the +resulting file will be invalid. For transcoding from an existing JPEG file, +we recommend using jpeg_copy_critical_parameters(). This routine initializes +all the compression parameters to default values (like jpeg_set_defaults()), +then copies the critical information from a source decompression object. +The decompression object should have just been used to read the entire +JPEG input file --- that is, it should be awaiting jpeg_finish_decompress(). + +jpeg_write_coefficients() marks all tables stored in the compression object +as needing to be written to the output file (thus, it acts like +jpeg_start_compress(cinfo, TRUE)). This is for safety's sake, to avoid +emitting abbreviated JPEG files by accident. If you really want to emit an +abbreviated JPEG file, call jpeg_suppress_tables(), or set the tables' +individual sent_table flags, between calling jpeg_write_coefficients() and +jpeg_finish_compress(). + + +Progress monitoring +------------------- + +Some applications may need to regain control from the JPEG library every so +often. The typical use of this feature is to produce a percent-done bar or +other progress display. (For a simple example, see cjpeg.c or djpeg.c.) +Although you do get control back frequently during the data-transferring pass +(the jpeg_read_scanlines or jpeg_write_scanlines loop), any additional passes +will occur inside jpeg_finish_compress or jpeg_start_decompress; those +routines may take a long time to execute, and you don't get control back +until they are done. + +You can define a progress-monitor routine which will be called periodically +by the library. No guarantees are made about how often this call will occur, +so we don't recommend you use it for mouse tracking or anything like that. +At present, a call will occur once per MCU row, scanline, or sample row +group, whichever unit is convenient for the current processing mode; so the +wider the image, the longer the time between calls. During the data +transferring pass, only one call occurs per call of jpeg_read_scanlines or +jpeg_write_scanlines, so don't pass a large number of scanlines at once if +you want fine resolution in the progress count. (If you really need to use +the callback mechanism for time-critical tasks like mouse tracking, you could +insert additional calls inside some of the library's inner loops.) + +To establish a progress-monitor callback, create a struct jpeg_progress_mgr, +fill in its progress_monitor field with a pointer to your callback routine, +and set cinfo->progress to point to the struct. The callback will be called +whenever cinfo->progress is non-NULL. (This pointer is set to NULL by +jpeg_create_compress or jpeg_create_decompress; the library will not change +it thereafter. So if you allocate dynamic storage for the progress struct, +make sure it will live as long as the JPEG object does. Allocating from the +JPEG memory manager with lifetime JPOOL_PERMANENT will work nicely.) You +can use the same callback routine for both compression and decompression. + +The jpeg_progress_mgr struct contains four fields which are set by the library: + long pass_counter; /* work units completed in this pass */ + long pass_limit; /* total number of work units in this pass */ + int completed_passes; /* passes completed so far */ + int total_passes; /* total number of passes expected */ +During any one pass, pass_counter increases from 0 up to (not including) +pass_limit; the step size is usually but not necessarily 1. The pass_limit +value may change from one pass to another. The expected total number of +passes is in total_passes, and the number of passes already completed is in +completed_passes. Thus the fraction of work completed may be estimated as + completed_passes + (pass_counter/pass_limit) + -------------------------------------------- + total_passes +ignoring the fact that the passes may not be equal amounts of work. + +When decompressing, pass_limit can even change within a pass, because it +depends on the number of scans in the JPEG file, which isn't always known in +advance. The computed fraction-of-work-done may jump suddenly (if the library +discovers it has overestimated the number of scans) or even decrease (in the +opposite case). It is not wise to put great faith in the work estimate. + +When using the decompressor's buffered-image mode, the progress monitor work +estimate is likely to be completely unhelpful, because the library has no way +to know how many output passes will be demanded of it. Currently, the library +sets total_passes based on the assumption that there will be one more output +pass if the input file end hasn't yet been read (jpeg_input_complete() isn't +TRUE), but no more output passes if the file end has been reached when the +output pass is started. This means that total_passes will rise as additional +output passes are requested. If you have a way of determining the input file +size, estimating progress based on the fraction of the file that's been read +will probably be more useful than using the library's value. + + +Memory management +----------------- + +This section covers some key facts about the JPEG library's built-in memory +manager. For more info, please read structure.txt's section about the memory +manager, and consult the source code if necessary. + +All memory and temporary file allocation within the library is done via the +memory manager. If necessary, you can replace the "back end" of the memory +manager to control allocation yourself (for example, if you don't want the +library to use malloc() and free() for some reason). + +Some data is allocated "permanently" and will not be freed until the JPEG +object is destroyed. Most data is allocated "per image" and is freed by +jpeg_finish_compress, jpeg_finish_decompress, or jpeg_abort. You can call the +memory manager yourself to allocate structures that will automatically be +freed at these times. Typical code for this is + ptr = (*cinfo->mem->alloc_small) ((j_common_ptr) cinfo, JPOOL_IMAGE, size); +Use JPOOL_PERMANENT to get storage that lasts as long as the JPEG object. +Use alloc_large instead of alloc_small for anything bigger than a few Kbytes. +There are also alloc_sarray and alloc_barray routines that automatically +build 2-D sample or block arrays. + +The library's minimum space requirements to process an image depend on the +image's width, but not on its height, because the library ordinarily works +with "strip" buffers that are as wide as the image but just a few rows high. +Some operating modes (eg, two-pass color quantization) require full-image +buffers. Such buffers are treated as "virtual arrays": only the current strip +need be in memory, and the rest can be swapped out to a temporary file. + +If you use the simplest memory manager back end (jmemnobs.c), then no +temporary files are used; virtual arrays are simply malloc()'d. Images bigger +than memory can be processed only if your system supports virtual memory. +The other memory manager back ends support temporary files of various flavors +and thus work in machines without virtual memory. They may also be useful on +Unix machines if you need to process images that exceed available swap space. + +When using temporary files, the library will make the in-memory buffers for +its virtual arrays just big enough to stay within a "maximum memory" setting. +Your application can set this limit by setting cinfo->mem->max_memory_to_use +after creating the JPEG object. (Of course, there is still a minimum size for +the buffers, so the max-memory setting is effective only if it is bigger than +the minimum space needed.) If you allocate any large structures yourself, you +must allocate them before jpeg_start_compress() or jpeg_start_decompress() in +order to have them counted against the max memory limit. Also keep in mind +that space allocated with alloc_small() is ignored, on the assumption that +it's too small to be worth worrying about; so a reasonable safety margin +should be left when setting max_memory_to_use. + +If you use the jmemname.c or jmemdos.c memory manager back end, it is +important to clean up the JPEG object properly to ensure that the temporary +files get deleted. (This is especially crucial with jmemdos.c, where the +"temporary files" may be extended-memory segments; if they are not freed, +DOS will require a reboot to recover the memory.) Thus, with these memory +managers, it's a good idea to provide a signal handler that will trap any +early exit from your program. The handler should call either jpeg_abort() +or jpeg_destroy() for any active JPEG objects. A handler is not needed with +jmemnobs.c, and shouldn't be necessary with jmemansi.c or jmemmac.c either, +since the C library is supposed to take care of deleting files made with +tmpfile(). + + +Memory usage +------------ + +Working memory requirements while performing compression or decompression +depend on image dimensions, image characteristics (such as colorspace and +JPEG process), and operating mode (application-selected options). + +As of v6b, the decompressor requires: + 1. About 24K in more-or-less-fixed-size data. This varies a bit depending + on operating mode and image characteristics (particularly color vs. + grayscale), but it doesn't depend on image dimensions. + 2. Strip buffers (of size proportional to the image width) for IDCT and + upsampling results. The worst case for commonly used sampling factors + is about 34 bytes * width in pixels for a color image. A grayscale image + only needs about 8 bytes per pixel column. + 3. A full-image DCT coefficient buffer is needed to decode a multi-scan JPEG + file (including progressive JPEGs), or whenever you select buffered-image + mode. This takes 2 bytes/coefficient. At typical 2x2 sampling, that's + 3 bytes per pixel for a color image. Worst case (1x1 sampling) requires + 6 bytes/pixel. For grayscale, figure 2 bytes/pixel. + 4. To perform 2-pass color quantization, the decompressor also needs a + 128K color lookup table and a full-image pixel buffer (3 bytes/pixel). +This does not count any memory allocated by the application, such as a +buffer to hold the final output image. + +The above figures are valid for 8-bit JPEG data precision and a machine with +32-bit ints. For 9-bit to 12-bit JPEG data, double the size of the strip +buffers and quantization pixel buffer. The "fixed-size" data will be +somewhat smaller with 16-bit ints, larger with 64-bit ints. Also, CMYK +or other unusual color spaces will require different amounts of space. + +The full-image coefficient and pixel buffers, if needed at all, do not +have to be fully RAM resident; you can have the library use temporary +files instead when the total memory usage would exceed a limit you set. +(But if your OS supports virtual memory, it's probably better to just use +jmemnobs and let the OS do the swapping.) + +The compressor's memory requirements are similar, except that it has no need +for color quantization. Also, it needs a full-image DCT coefficient buffer +if Huffman-table optimization is asked for, even if progressive mode is not +requested. + +If you need more detailed information about memory usage in a particular +situation, you can enable the MEM_STATS code in jmemmgr.c. + + +Library compile-time options +---------------------------- + +A number of compile-time options are available by modifying jmorecfg.h. + +The IJG code currently supports 8-bit to 12-bit sample data precision by +defining BITS_IN_JSAMPLE as 8, 9, 10, 11, or 12. +Note that a value larger than 8 causes JSAMPLE to be larger than a char, +so it affects the surrounding application's image data. +The sample applications cjpeg and djpeg can support deeper than 8-bit data +only for PPM and GIF file formats; you must disable the other file formats +to compile a 9-bit to 12-bit cjpeg or djpeg. (install.txt has more +information about that.) +Run-time selection and conversion of data precision are currently not +supported and may be added later. +Exception: The transcoding part (jpegtran) supports all settings in a +single instance, since it operates on the level of DCT coefficients and +not sample values. +(If you need to include an 8-bit library and a 9-bit to 12-bit library for +compression or decompression in a single application, you could probably do +it by defining NEED_SHORT_EXTERNAL_NAMES for just one of the copies. You'd +have to access the 8-bit and the 9-bit to 12-bit copies from separate +application source files. This is untested ... if you try it, we'd like to +hear whether it works!) + +Note that the standard Huffman tables are only valid for 8-bit data precision. +If you selected more than 8-bit data precision, cjpeg uses arithmetic coding +by default. The Huffman encoder normally uses entropy optimization to +compute usable tables for higher precision. Otherwise, you'll have to +supply different default Huffman tables. You may also want to supply your +own DCT quantization tables; the existing quality-scaling code has been +developed for 8-bit use, and probably doesn't generate especially good tables +for 9-bit to 12-bit. + +The maximum number of components (color channels) in the image is determined +by MAX_COMPONENTS. The JPEG standard allows up to 255 components, but we +expect that few applications will need more than four or so. + +On machines with unusual data type sizes, you may be able to improve +performance or reduce memory space by tweaking the various typedefs in +jmorecfg.h. In particular, on some RISC CPUs, access to arrays of "short"s +is quite slow; consider trading memory for speed by making JCOEF, INT16, and +UINT16 be "int" or "unsigned int". UINT8 is also a candidate to become int. +You probably don't want to make JSAMPLE be int unless you have lots of memory +to burn. + +You can reduce the size of the library by compiling out various optional +functions. To do this, undefine xxx_SUPPORTED symbols as necessary. + +You can also save a few K by not having text error messages in the library; +the standard error message table occupies about 5Kb. This is particularly +reasonable for embedded applications where there's no good way to display +a message anyway. To do this, remove the creation of the message table +(jpeg_std_message_table[]) from jerror.c, and alter format_message to do +something reasonable without it. You could output the numeric value of the +message code number, for example. If you do this, you can also save a couple +more K by modifying the TRACEMSn() macros in jerror.h to expand to nothing; +you don't need trace capability anyway, right? + + +Portability considerations +-------------------------- + +The JPEG library has been written to be extremely portable; the sample +applications cjpeg and djpeg are slightly less so. This section summarizes +the design goals in this area. (If you encounter any bugs that cause the +library to be less portable than is claimed here, we'd appreciate hearing +about them.) + +The code works fine on ANSI C, C++, and pre-ANSI C compilers, using any of +the popular system include file setups, and some not-so-popular ones too. +See install.txt for configuration procedures. + +The code is not dependent on the exact sizes of the C data types. As +distributed, we make the assumptions that + char is at least 8 bits wide + short is at least 16 bits wide + int is at least 16 bits wide + long is at least 32 bits wide +(These are the minimum requirements of the ANSI C standard.) Wider types will +work fine, although memory may be used inefficiently if char is much larger +than 8 bits or short is much bigger than 16 bits. The code should work +equally well with 16- or 32-bit ints. + +In a system where these assumptions are not met, you may be able to make the +code work by modifying the typedefs in jmorecfg.h. However, you will probably +have difficulty if int is less than 16 bits wide, since references to plain +int abound in the code. + +char can be either signed or unsigned, although the code runs faster if an +unsigned char type is available. If char is wider than 8 bits, you will need +to redefine JOCTET and/or provide custom data source/destination managers so +that JOCTET represents exactly 8 bits of data on external storage. + +The JPEG library proper does not assume ASCII representation of characters. +But some of the image file I/O modules in cjpeg/djpeg do have ASCII +dependencies in file-header manipulation; so does cjpeg's select_file_type() +routine. + +The JPEG library does not rely heavily on the C library. In particular, C +stdio is used only by the data source/destination modules and the error +handler, all of which are application-replaceable. (cjpeg/djpeg are more +heavily dependent on stdio.) malloc and free are called only from the memory +manager "back end" module, so you can use a different memory allocator by +replacing that one file. + +The code generally assumes that C names must be unique in the first 15 +characters. However, global function names can be made unique in the +first 6 characters by defining NEED_SHORT_EXTERNAL_NAMES. + +More info about porting the code may be gleaned by reading jconfig.txt, +jmorecfg.h, and jinclude.h. + + +Notes for MS-DOS implementors +----------------------------- + +The IJG code is designed to work efficiently in 80x86 "small" or "medium" +memory models (i.e., data pointers are 16 bits unless explicitly declared +"far"; code pointers can be either size). You may be able to use small +model to compile cjpeg or djpeg by itself, but you will probably have to use +medium model for any larger application. This won't make much difference in +performance. You *will* take a noticeable performance hit if you use a +large-data memory model (perhaps 10%-25%), and you should avoid "huge" model +if at all possible. + +The JPEG library typically needs 2Kb-3Kb of stack space. It will also +malloc about 20K-30K of near heap space while executing (and lots of far +heap, but that doesn't count in this calculation). This figure will vary +depending on selected operating mode, and to a lesser extent on image size. +There is also about 5Kb-6Kb of constant data which will be allocated in the +near data segment (about 4Kb of this is the error message table). +Thus you have perhaps 20K available for other modules' static data and near +heap space before you need to go to a larger memory model. The C library's +static data will account for several K of this, but that still leaves a good +deal for your needs. (If you are tight on space, you could reduce the sizes +of the I/O buffers allocated by jdatasrc.c and jdatadst.c, say from 4K to +1K. Another possibility is to move the error message table to far memory; +this should be doable with only localized hacking on jerror.c.) + +About 2K of the near heap space is "permanent" memory that will not be +released until you destroy the JPEG object. This is only an issue if you +save a JPEG object between compression or decompression operations. + +Far data space may also be a tight resource when you are dealing with large +images. The most memory-intensive case is decompression with two-pass color +quantization, or single-pass quantization to an externally supplied color +map. This requires a 128Kb color lookup table plus strip buffers amounting +to about 40 bytes per column for typical sampling ratios (eg, about 25600 +bytes for a 640-pixel-wide image). You may not be able to process wide +images if you have large data structures of your own. + +Of course, all of these concerns vanish if you use a 32-bit flat-memory-model +compiler, such as DJGPP or Watcom C. We highly recommend flat model if you +can use it; the JPEG library is significantly faster in flat model. diff --git a/project/jni/sdl2_image/external/jpeg-9b/ltmain.sh b/project/jni/sdl2_image/external/jpeg-9b/ltmain.sh new file mode 100644 index 000000000..0f0a2da3f --- /dev/null +++ b/project/jni/sdl2_image/external/jpeg-9b/ltmain.sh @@ -0,0 +1,11147 @@ +#! /bin/sh +## DO NOT EDIT - This file generated from ./build-aux/ltmain.in +## by inline-source v2014-01-03.01 + +# libtool (GNU libtool) 2.4.6 +# Provide generalized library-building support services. +# Written by Gordon Matzigkeit , 1996 + +# Copyright (C) 1996-2015 Free Software Foundation, Inc. +# This is free software; see the source for copying conditions.

Lane, Guido Vollbeding. +This file is part of the Independent JPEG Group's software. +For conditions of distribution and use, see the accompanying README file. + + +This file provides an overview of the architecture of the IJG JPEG software; +that is, the functions of the various modules in the system and the interfaces +between modules. For more precise details about any data structure or calling +convention, see the include files and comments in the source code. + +We assume that the reader is already somewhat familiar with the JPEG standard. +The README file includes references for learning about JPEG. The file +libjpeg.txt describes the library from the viewpoint of an application +programmer using the library; it's best to read that file before this one. +Also, the file coderules.txt describes the coding style conventions we use. + +In this document, JPEG-specific terminology follows the JPEG standard: + A "component" means a color channel, e.g., Red or Luminance. + A "sample" is a single component value (i.e., one number in the image data). + A "coefficient" is a frequency coefficient (a DCT transform output number). + A "block" is an array of samples or coefficients. + An "MCU" (minimum coded unit) is an interleaved set of blocks of size + determined by the sampling factors, or a single block in a + noninterleaved scan. +We do not use the terms "pixel" and "sample" interchangeably. When we say +pixel, we mean an element of the full-size image, while a sample is an element +of the downsampled image. Thus the number of samples may vary across +components while the number of pixels does not. (This terminology is not used +rigorously throughout the code, but it is used in places where confusion would +otherwise result.) + + +*** System features *** + +The IJG distribution contains two parts: + * A subroutine library for JPEG compression and decompression. + * cjpeg/djpeg, two sample applications that use the library to transform + JFIF JPEG files to and from several other image formats. +cjpeg/djpeg are of no great intellectual complexity: they merely add a simple +command-line user interface and I/O routines for several uncompressed image +formats. This document concentrates on the library itself. + +We desire the library to be capable of supporting all JPEG baseline, extended +sequential, and progressive DCT processes. The library does not support the +hierarchical or lossless processes defined in the standard. + +Within these limits, any set of compression parameters allowed by the JPEG +spec should be readable for decompression. (We can be more restrictive about +what formats we can generate.) Although the system design allows for all +parameter values, some uncommon settings are not yet implemented and may +never be; nonintegral sampling ratios are the prime example. Furthermore, +we treat 8-bit vs. 12-bit data precision as a compile-time switch, not a +run-time option, because most machines can store 8-bit pixels much more +compactly than 12-bit. + +By itself, the library handles only interchange JPEG datastreams --- in +particular the widely used JFIF file format. The library can be used by +surrounding code to process interchange or abbreviated JPEG datastreams that +are embedded in more complex file formats. (For example, libtiff uses this +library to implement JPEG compression within the TIFF file format.) + +The library includes a substantial amount of code that is not covered by the +JPEG standard but is necessary for typical applications of JPEG. These +functions preprocess the image before JPEG compression or postprocess it after +decompression. They include colorspace conversion, downsampling/upsampling, +and color quantization. This code can be omitted if not needed. + +A wide range of quality vs. speed tradeoffs are possible in JPEG processing, +and even more so in decompression postprocessing. The decompression library +provides multiple implementations that cover most of the useful tradeoffs, +ranging from very-high-quality down to fast-preview operation. On the +compression side we have generally not provided low-quality choices, since +compression is normally less time-critical. It should be understood that the +low-quality modes may not meet the JPEG standard's accuracy requirements; +nonetheless, they are useful for viewers. + + +*** Portability issues *** + +Portability is an essential requirement for the library. The key portability +issues that show up at the level of system architecture are: + +1. Memory usage. We want the code to be able to run on PC-class machines +with limited memory. Images should therefore be processed sequentially (in +strips), to avoid holding the whole image in memory at once. Where a +full-image buffer is necessary, we should be able to use either virtual memory +or temporary files. + +2. Near/far pointer distinction. To run efficiently on 80x86 machines, the +code should distinguish "small" objects (kept in near data space) from +"large" ones (kept in far data space). This is an annoying restriction, but +fortunately it does not impact code quality for less brain-damaged machines, +and the source code clutter turns out to be minimal with sufficient use of +pointer typedefs. + +3. Data precision. We assume that "char" is at least 8 bits, "short" and +"int" at least 16, "long" at least 32. The code will work fine with larger +data sizes, although memory may be used inefficiently in some cases. However, +the JPEG compressed datastream must ultimately appear on external storage as a +sequence of 8-bit bytes if it is to conform to the standard. This may pose a +problem on machines where char is wider than 8 bits. The library represents +compressed data as an array of values of typedef JOCTET. If no data type +exactly 8 bits wide is available, custom data source and data destination +modules must be written to unpack and pack the chosen JOCTET datatype into +8-bit external representation. + + +*** System overview *** + +The compressor and decompressor are each divided into two main sections: +the JPEG compressor or decompressor proper, and the preprocessing or +postprocessing functions. The interface between these two sections is the +image data that the official JPEG spec regards as its input or output: this +data is in the colorspace to be used for compression, and it is downsampled +to the sampling factors to be used. The preprocessing and postprocessing +steps are responsible for converting a normal image representation to or from +this form. (Those few applications that want to deal with YCbCr downsampled +data can skip the preprocessing or postprocessing step.) + +Looking more closely, the compressor library contains the following main +elements: + + Preprocessing: + * Color space conversion (e.g., RGB to YCbCr). + * Edge expansion and downsampling. Optionally, this step can do simple + smoothing --- this is often helpful for low-quality source data. + JPEG proper: + * MCU assembly, DCT, quantization. + * Entropy coding (sequential or progressive, Huffman or arithmetic). + +In addition to these modules we need overall control, marker generation, +and support code (memory management & error handling). There is also a +module responsible for physically writing the output data --- typically +this is just an interface to fwrite(), but some applications may need to +do something else with the data. + +The decompressor library contains the following main elements: + + JPEG proper: + * Entropy decoding (sequential or progressive, Huffman or arithmetic). + * Dequantization, inverse DCT, MCU disassembly. + Postprocessing: + * Upsampling. Optionally, this step may be able to do more general + rescaling of the image. + * Color space conversion (e.g., YCbCr to RGB). This step may also + provide gamma adjustment [ currently it does not ]. + * Optional color quantization (e.g., reduction to 256 colors). + * Optional color precision reduction (e.g., 24-bit to 15-bit color). + [This feature is not currently implemented.] + +We also need overall control, marker parsing, and a data source module. +The support code (memory management & error handling) can be shared with +the compression half of the library. + +There may be several implementations of each of these elements, particularly +in the decompressor, where a wide range of speed/quality tradeoffs is very +useful. It must be understood that some of the best speedups involve +merging adjacent steps in the pipeline. For example, upsampling, color space +conversion, and color quantization might all be done at once when using a +low-quality ordered-dither technique. The system architecture is designed to +allow such merging where appropriate. + + +Note: it is convenient to regard edge expansion (padding to block boundaries) +as a preprocessing/postprocessing function, even though the JPEG spec includes +it in compression/decompression. We do this because downsampling/upsampling +can be simplified a little if they work on padded data: it's not necessary to +have special cases at the right and bottom edges. Therefore the interface +buffer is always an integral number of blocks wide and high, and we expect +compression preprocessing to pad the source data properly. Padding will occur +only to the next block (block_size-sample) boundary. In an interleaved-scan +situation, additional dummy blocks may be used to fill out MCUs, but the MCU +assembly and disassembly logic will create or discard these blocks internally. +(This is advantageous for speed reasons, since we avoid DCTing the dummy +blocks. It also permits a small reduction in file size, because the +compressor can choose dummy block contents so as to minimize their size +in compressed form. Finally, it makes the interface buffer specification +independent of whether the file is actually interleaved or not.) +Applications that wish to deal directly with the downsampled data must +provide similar buffering and padding for odd-sized images. + + +*** Poor man's object-oriented programming *** + +It should be clear by now that we have a lot of quasi-independent processing +steps, many of which have several possible behaviors. To avoid cluttering the +code with lots of switch statements, we use a simple form of object-style +programming to separate out the different possibilities. + +For example, two different color quantization algorithms could be implemented +as two separate modules that present the same external interface; at runtime, +the calling code will access the proper module indirectly through an "object". + +We can get the limited features we need while staying within portable C. +The basic tool is a function pointer. An "object" is just a struct +containing one or more function pointer fields, each of which corresponds to +a method name in real object-oriented languages. During initialization we +fill in the function pointers with references to whichever module we have +determined we need to use in this run. Then invocation of the module is done +by indirecting through a function pointer; on most machines this is no more +expensive than a switch statement, which would be the only other way of +making the required run-time choice. The really significant benefit, of +course, is keeping the source code clean and well structured. + +We can also arrange to have private storage that varies between different +implementations of the same kind of object. We do this by making all the +module-specific object structs be separately allocated entities, which will +be accessed via pointers in the master compression or decompression struct. +The "public" fields or methods for a given kind of object are specified by +a commonly known struct. But a module's initialization code can allocate +a larger struct that contains the common struct as its first member, plus +additional private fields. With appropriate pointer casting, the module's +internal functions can access these private fields. (For a simple example, +see jdatadst.c, which implements the external interface specified by struct +jpeg_destination_mgr, but adds extra fields.) + +(Of course this would all be a lot easier if we were using C++, but we are +not yet prepared to assume that everyone has a C++ compiler.) + +An important benefit of this scheme is that it is easy to provide multiple +versions of any method, each tuned to a particular case. While a lot of +precalculation might be done to select an optimal implementation of a method, +the cost per invocation is constant. For example, the upsampling step might +have a "generic" method, plus one or more "hardwired" methods for the most +popular sampling factors; the hardwired methods would be faster because they'd +use straight-line code instead of for-loops. The cost to determine which +method to use is paid only once, at startup, and the selection criteria are +hidden from the callers of the method. + +This plan differs a little bit from usual object-oriented structures, in that +only one instance of each object class will exist during execution. The +reason for having the class structure is that on different runs we may create +different instances (choose to execute different modules). You can think of +the term "method" as denoting the common interface presented by a particular +set of interchangeable functions, and "object" as denoting a group of related +methods, or the total shared interface behavior of a group of modules. + + +*** Overall control structure *** + +We previously mentioned the need for overall control logic in the compression +and decompression libraries. In IJG implementations prior to v5, overall +control was mostly provided by "pipeline control" modules, which proved to be +large, unwieldy, and hard to understand. To improve the situation, the +control logic has been subdivided into multiple modules. The control modules +consist of: + +1. Master control for module selection and initialization. This has two +responsibilities: + + 1A. Startup initialization at the beginning of image processing. + The individual processing modules to be used in this run are selected + and given initialization calls. + + 1B. Per-pass control. This determines how many passes will be performed + and calls each active processing module to configure itself + appropriately at the beginning of each pass. End-of-pass processing, + where necessary, is also invoked from the master control module. + + Method selection is partially distributed, in that a particular processing + module may contain several possible implementations of a particular method, + which it will select among when given its initialization call. The master + control code need only be concerned with decisions that affect more than + one module. + +2. Data buffering control. A separate control module exists for each + inter-processing-step data buffer. This module is responsible for + invoking the processing steps that write or read that data buffer. + +Each buffer controller sees the world as follows: + +input data => processing step A => buffer => processing step B => output data + | | | + ------------------ controller ------------------ + +The controller knows the dataflow requirements of steps A and B: how much data +they want to accept in one chunk and how much they output in one chunk. Its +function is to manage its buffer and call A and B at the proper times. + +A data buffer control module may itself be viewed as a processing step by a +higher-level control module; thus the control modules form a binary tree with +elementary processing steps at the leaves of the tree. + +The control modules are objects. A considerable amount of flexibility can +be had by replacing implementations of a control module. For example: +* Merging of adjacent steps in the pipeline is done by replacing a control + module and its pair of processing-step modules with a single processing- + step module. (Hence the possible merges are determined by the tree of + control modules.) +* In some processing modes, a given interstep buffer need only be a "strip" + buffer large enough to accommodate the desired data chunk sizes. In other + modes, a full-image buffer is needed and several passes are required. + The control module determines which kind of buffer is used and manipulates + virtual array buffers as needed. One or both processing steps may be + unaware of the multi-pass behavior. + +In theory, we might be able to make all of the data buffer controllers +interchangeable and provide just one set of implementations for all. In +practice, each one contains considerable special-case processing for its +particular job. The buffer controller concept should be regarded as an +overall system structuring principle, not as a complete description of the +task performed by any one controller. + + +*** Compression object structure *** + +Here is a sketch of the logical structure of the JPEG compression library: + + |-- Colorspace conversion + |-- Preprocessing controller --| + | |-- Downsampling +Main controller --| + | |-- Forward DCT, quantize + |-- Coefficient controller --| + |-- Entropy encoding + +This sketch also describes the flow of control (subroutine calls) during +typical image data processing. Each of the components shown in the diagram is +an "object" which may have several different implementations available. One +or more source code files contain the actual implementation(s) of each object. + +The objects shown above are: + +* Main controller: buffer controller for the subsampled-data buffer, which + holds the preprocessed input data. This controller invokes preprocessing to + fill the subsampled-data buffer, and JPEG compression to empty it. There is + usually no need for a full-image buffer here; a strip buffer is adequate. + +* Preprocessing controller: buffer controller for the downsampling input data + buffer, which lies between colorspace conversion and downsampling. Note + that a unified conversion/downsampling module would probably replace this + controller entirely. + +* Colorspace conversion: converts application image data into the desired + JPEG color space; also changes the data from pixel-interleaved layout to + separate component planes. Processes one pixel row at a time. + +* Downsampling: performs reduction of chroma components as required. + Optionally may perform pixel-level smoothing as well. Processes a "row + group" at a time, where a row group is defined as Vmax pixel rows of each + component before downsampling, and Vk sample rows afterwards (remember Vk + differs across components). Some downsampling or smoothing algorithms may + require context rows above and below the current row group; the + preprocessing controller is responsible for supplying these rows via proper + buffering. The downsampler is responsible for edge expansion at the right + edge (i.e., extending each sample row to a multiple of block_size samples); + but the preprocessing controller is responsible for vertical edge expansion + (i.e., duplicating the bottom sample row as needed to make a multiple of + block_size rows). + +* Coefficient controller: buffer controller for the DCT-coefficient data. + This controller handles MCU assembly, including insertion of dummy DCT + blocks when needed at the right or bottom edge. When performing + Huffman-code optimization or emitting a multiscan JPEG file, this + controller is responsible for buffering the full image. The equivalent of + one fully interleaved MCU row of subsampled data is processed per call, + even when the JPEG file is noninterleaved. + +* Forward DCT and quantization: Perform DCT, quantize, and emit coefficients. + Works on one or more DCT blocks at a time. (Note: the coefficients are now + emitted in normal array order, which the entropy encoder is expected to + convert to zigzag order as necessary. Prior versions of the IJG code did + the conversion to zigzag order within the quantization step.) + +* Entropy encoding: Perform Huffman or arithmetic entropy coding and emit the + coded data to the data destination module. Works on one MCU per call. + For progressive JPEG, the same DCT blocks are fed to the entropy coder + during each pass, and the coder must emit the appropriate subset of + coefficients. + +In addition to the above objects, the compression library includes these +objects: + +* Master control: determines the number of passes required, controls overall + and per-pass initialization of the other modules. + +* Marker writing: generates JPEG markers (except for RSTn, which is emitted + by the entropy encoder when needed). + +* Data destination manager: writes the output JPEG datastream to its final + destination (e.g., a file). The destination manager supplied with the + library knows how to write to a stdio stream or to a memory buffer; + for other behaviors, the surrounding application may provide its own + destination manager. + +* Memory manager: allocates and releases memory, controls virtual arrays + (with backing store management, where required). + +* Error handler: performs formatting and output of error and trace messages; + determines handling of nonfatal errors. The surrounding application may + override some or all of this object's methods to change error handling. + +* Progress monitor: supports output of "percent-done" progress reports. + This object represents an optional callback to the surrounding application: + if wanted, it must be supplied by the application. + +The error handler, destination manager, and progress monitor objects are +defined as separate objects in order to simplify application-specific +customization of the JPEG library. A surrounding application may override +individual methods or supply its own all-new implementation of one of these +objects. The object interfaces for these objects are therefore treated as +part of the application interface of the library, whereas the other objects +are internal to the library. + +The error handler and memory manager are shared by JPEG compression and +decompression; the progress monitor, if used, may be shared as well. + + +*** Decompression object structure *** + +Here is a sketch of the logical structure of the JPEG decompression library: + + |-- Entropy decoding + |-- Coefficient controller --| + | |-- Dequantize, Inverse DCT +Main controller --| + | |-- Upsampling + |-- Postprocessing controller --| |-- Colorspace conversion + |-- Color quantization + |-- Color precision reduction + +As before, this diagram also represents typical control flow. The objects +shown are: + +* Main controller: buffer controller for the subsampled-data buffer, which + holds the output of JPEG decompression proper. This controller's primary + task is to feed the postprocessing procedure. Some upsampling algorithms + may require context rows above and below the current row group; when this + is true, the main controller is responsible for managing its buffer so as + to make context rows available. In the current design, the main buffer is + always a strip buffer; a full-image buffer is never required. + +* Coefficient controller: buffer controller for the DCT-coefficient data. + This controller handles MCU disassembly, including deletion of any dummy + DCT blocks at the right or bottom edge. When reading a multiscan JPEG + file, this controller is responsible for buffering the full image. + (Buffering DCT coefficients, rather than samples, is necessary to support + progressive JPEG.) The equivalent of one fully interleaved MCU row of + subsampled data is processed per call, even when the source JPEG file is + noninterleaved. + +* Entropy decoding: Read coded data from the data source module and perform + Huffman or arithmetic entropy decoding. Works on one MCU per call. + For progressive JPEG decoding, the coefficient controller supplies the prior + coefficients of each MCU (initially all zeroes), which the entropy decoder + modifies in each scan. + +* Dequantization and inverse DCT: like it says. Note that the coefficients + buffered by the coefficient controller have NOT been dequantized; we + merge dequantization and inverse DCT into a single step for speed reasons. + When scaled-down output is asked for, simplified DCT algorithms may be used + that need fewer coefficients and emit fewer samples per DCT block, not the + full 8x8. Works on one DCT block at a time. + +* Postprocessing controller: buffer controller for the color quantization + input buffer, when quantization is in use. (Without quantization, this + controller just calls the upsampler.) For two-pass quantization, this + controller is responsible for buffering the full-image data. + +* Upsampling: restores chroma components to full size. (May support more + general output rescaling, too. Note that if undersized DCT outputs have + been emitted by the DCT module, this module must adjust so that properly + sized outputs are created.) Works on one row group at a time. This module + also calls the color conversion module, so its top level is effectively a + buffer controller for the upsampling->color conversion buffer. However, in + all but the highest-quality operating modes, upsampling and color + conversion are likely to be merged into a single step. + +* Colorspace conversion: convert from JPEG color space to output color space, + and change data layout from separate component planes to pixel-interleaved. + Works on one pixel row at a time. + +* Color quantization: reduce the data to colormapped form, using either an + externally specified colormap or an internally generated one. This module + is not used for full-color output. Works on one pixel row at a time; may + require two passes to generate a color map. Note that the output will + always be a single component representing colormap indexes. In the current + design, the output values are JSAMPLEs, so an 8-bit compilation cannot + quantize to more than 256 colors. This is unlikely to be a problem in + practice. + +* Color reduction: this module handles color precision reduction, e.g., + generating 15-bit color (5 bits/primary) from JPEG's 24-bit output. + Not quite clear yet how this should be handled... should we merge it with + colorspace conversion??? + +Note that some high-speed operating modes might condense the entire +postprocessing sequence to a single module (upsample, color convert, and +quantize in one step). + +In addition to the above objects, the decompression library includes these +objects: + +* Master control: determines the number of passes required, controls overall + and per-pass initialization of the other modules. This is subdivided into + input and output control: jdinput.c controls only input-side processing, + while jdmaster.c handles overall initialization and output-side control. + +* Marker reading: decodes JPEG markers (except for RSTn). + +* Data source manager: supplies the input JPEG datastream. The source + manager supplied with the library knows how to read from a stdio stream + or from a memory buffer; for other behaviors, the surrounding application + may provide its own source manager. + +* Memory manager: same as for compression library. + +* Error handler: same as for compression library. + +* Progress monitor: same as for compression library. + +As with compression, the data source manager, error handler, and progress +monitor are candidates for replacement by a surrounding application. + + +*** Decompression input and output separation *** + +To support efficient incremental display of progressive JPEG files, the +decompressor is divided into two sections that can run independently: + +1. Data input includes marker parsing, entropy decoding, and input into the + coefficient controller's DCT coefficient buffer. Note that this + processing is relatively cheap and fast. + +2. Data output reads from the DCT coefficient buffer and performs the IDCT + and all postprocessing steps. + +For a progressive JPEG file, the data input processing is allowed to get +arbitrarily far ahead of the data output processing. (This occurs only +if the application calls jpeg_consume_input(); otherwise input and output +run in lockstep, since the input section is called only when the output +section needs more data.) In this way the application can avoid making +extra display passes when data is arriving faster than the display pass +can run. Furthermore, it is possible to abort an output pass without +losing anything, since the coefficient buffer is read-only as far as the +output section is concerned. See libjpeg.txt for more detail. + +A full-image coefficient array is only created if the JPEG file has multiple +scans (or if the application specifies buffered-image mode anyway). When +reading a single-scan file, the coefficient controller normally creates only +a one-MCU buffer, so input and output processing must run in lockstep in this +case. jpeg_consume_input() is effectively a no-op in this situation. + +The main impact of dividing the decompressor in this fashion is that we must +be very careful with shared variables in the cinfo data structure. Each +variable that can change during the course of decompression must be +classified as belonging to data input or data output, and each section must +look only at its own variables. For example, the data output section may not +depend on any of the variables that describe the current scan in the JPEG +file, because these may change as the data input section advances into a new +scan. + +The progress monitor is (somewhat arbitrarily) defined to treat input of the +file as one pass when buffered-image mode is not used, and to ignore data +input work completely when buffered-image mode is used. Note that the +library has no reliable way to predict the number of passes when dealing +with a progressive JPEG file, nor can it predict the number of output passes +in buffered-image mode. So the work estimate is inherently bogus anyway. + +No comparable division is currently made in the compression library, because +there isn't any real need for it. + + +*** Data formats *** + +Arrays of pixel sample values use the following data structure: + + typedef something JSAMPLE; a pixel component value, 0..MAXJSAMPLE + typedef JSAMPLE *JSAMPROW; ptr to a row of samples + typedef JSAMPROW *JSAMPARRAY; ptr to a list of rows + typedef JSAMPARRAY *JSAMPIMAGE; ptr to a list of color-component arrays + +The basic element type JSAMPLE will typically be one of unsigned char, +(signed) char, or short. Short will be used if samples wider than 8 bits are +to be supported (this is a compile-time option). Otherwise, unsigned char is +used if possible. If the compiler only supports signed chars, then it is +necessary to mask off the value when reading. Thus, all reads of JSAMPLE +values must be coded as "GETJSAMPLE(value)", where the macro will be defined +as "((value) & 0xFF)" on signed-char machines and "((int) (value))" elsewhere. + +With these conventions, JSAMPLE values can be assumed to be >= 0. This helps +simplify correct rounding during downsampling, etc. The JPEG standard's +specification that sample values run from -128..127 is accommodated by +subtracting 128 from the sample value in the DCT step. Similarly, during +decompression the output of the IDCT step will be immediately shifted back to +0..255. (NB: different values are required when 12-bit samples are in use. +The code is written in terms of MAXJSAMPLE and CENTERJSAMPLE, which will be +defined as 255 and 128 respectively in an 8-bit implementation, and as 4095 +and 2048 in a 12-bit implementation.) + +We use a pointer per row, rather than a two-dimensional JSAMPLE array. This +choice costs only a small amount of memory and has several benefits: +* Code using the data structure doesn't need to know the allocated width of + the rows. This simplifies edge expansion/compression, since we can work + in an array that's wider than the logical picture width. +* Indexing doesn't require multiplication; this is a performance win on many + machines. +* Arrays with more than 64K total elements can be supported even on machines + where malloc() cannot allocate chunks larger than 64K. +* The rows forming a component array may be allocated at different times + without extra copying. This trick allows some speedups in smoothing steps + that need access to the previous and next rows. + +Note that each color component is stored in a separate array; we don't use the +traditional layout in which the components of a pixel are stored together. +This simplifies coding of modules that work on each component independently, +because they don't need to know how many components there are. Furthermore, +we can read or write each component to a temporary file independently, which +is helpful when dealing with noninterleaved JPEG files. + +In general, a specific sample value is accessed by code such as + GETJSAMPLE(image[colorcomponent][row][col]) +where col is measured from the image left edge, but row is measured from the +first sample row currently in memory. Either of the first two indexings can +be precomputed by copying the relevant pointer. + + +Since most image-processing applications prefer to work on images in which +the components of a pixel are stored together, the data passed to or from the +surrounding application uses the traditional convention: a single pixel is +represented by N consecutive JSAMPLE values, and an image row is an array of +(# of color components)*(image width) JSAMPLEs. One or more rows of data can +be represented by a pointer of type JSAMPARRAY in this scheme. This scheme is +converted to component-wise storage inside the JPEG library. (Applications +that want to skip JPEG preprocessing or postprocessing will have to contend +with component-wise storage.) + + +Arrays of DCT-coefficient values use the following data structure: + + typedef short JCOEF; a 16-bit signed integer + typedef JCOEF JBLOCK[DCTSIZE2]; an 8x8 block of coefficients + typedef JBLOCK *JBLOCKROW; ptr to one horizontal row of 8x8 blocks + typedef JBLOCKROW *JBLOCKARRAY; ptr to a list of such rows + typedef JBLOCKARRAY *JBLOCKIMAGE; ptr to a list of color component arrays + +The underlying type is at least a 16-bit signed integer; while "short" is big +enough on all machines of interest, on some machines it is preferable to use +"int" for speed reasons, despite the storage cost. Coefficients are grouped +into 8x8 blocks (but we always use #defines DCTSIZE and DCTSIZE2 rather than +"8" and "64"). + +The contents of a coefficient block may be in either "natural" or zigzagged +order, and may be true values or divided by the quantization coefficients, +depending on where the block is in the processing pipeline. In the current +library, coefficient blocks are kept in natural order everywhere; the entropy +codecs zigzag or dezigzag the data as it is written or read. The blocks +contain quantized coefficients everywhere outside the DCT/IDCT subsystems. +(This latter decision may need to be revisited to support variable +quantization a la JPEG Part 3.) + +Notice that the allocation unit is now a row of 8x8 coefficient blocks, +corresponding to block_size rows of samples. Otherwise the structure +is much the same as for samples, and for the same reasons. + +On machines where malloc() can't handle a request bigger than 64Kb, this data +structure limits us to rows of less than 512 JBLOCKs, or a picture width of +4000+ pixels. This seems an acceptable restriction. + + +On 80x86 machines, the bottom-level pointer types (JSAMPROW and JBLOCKROW) +must be declared as "far" pointers, but the upper levels can be "near" +(implying that the pointer lists are allocated in the DS segment). +We use a #define symbol FAR, which expands to the "far" keyword when +compiling on 80x86 machines and to nothing elsewhere. + + +*** Suspendable processing *** + +In some applications it is desirable to use the JPEG library as an +incremental, memory-to-memory filter. In this situation the data source or +destination may be a limited-size buffer, and we can't rely on being able to +empty or refill the buffer at arbitrary times. Instead the application would +like to have control return from the library at buffer overflow/underrun, and +then resume compression or decompression at a later time. + +This scenario is supported for simple cases. (For anything more complex, we +recommend that the application "bite the bullet" and develop real multitasking +capability.) The libjpeg.txt file goes into more detail about the usage and +limitations of this capability; here we address the implications for library +structure. + +The essence of the problem is that the entropy codec (coder or decoder) must +be prepared to stop at arbitrary times. In turn, the controllers that call +the entropy codec must be able to stop before having produced or consumed all +the data that they normally would handle in one call. That part is reasonably +straightforward: we make the controller call interfaces include "progress +counters" which indicate the number of data chunks successfully processed, and +we require callers to test the counter rather than just assume all of the data +was processed. + +Rather than trying to restart at an arbitrary point, the current Huffman +codecs are designed to restart at the beginning of the current MCU after a +suspension due to buffer overflow/underrun. At the start of each call, the +codec's internal state is loaded from permanent storage (in the JPEG object +structures) into local variables. On successful completion of the MCU, the +permanent state is updated. (This copying is not very expensive, and may even +lead to *improved* performance if the local variables can be registerized.) +If a suspension occurs, the codec simply returns without updating the state, +thus effectively reverting to the start of the MCU. Note that this implies +leaving some data unprocessed in the source/destination buffer (ie, the +compressed partial MCU). The data source/destination module interfaces are +specified so as to make this possible. This also implies that the data buffer +must be large enough to hold a worst-case compressed MCU; a couple thousand +bytes should be enough. + +In a successive-approximation AC refinement scan, the progressive Huffman +decoder has to be able to undo assignments of newly nonzero coefficients if it +suspends before the MCU is complete, since decoding requires distinguishing +previously-zero and previously-nonzero coefficients. This is a bit tedious +but probably won't have much effect on performance. Other variants of Huffman +decoding need not worry about this, since they will just store the same values +again if forced to repeat the MCU. + +This approach would probably not work for an arithmetic codec, since its +modifiable state is quite large and couldn't be copied cheaply. Instead it +would have to suspend and resume exactly at the point of the buffer end. + +The JPEG marker reader is designed to cope with suspension at an arbitrary +point. It does so by backing up to the start of the marker parameter segment, +so the data buffer must be big enough to hold the largest marker of interest. +Again, a couple KB should be adequate. (A special "skip" convention is used +to bypass COM and APPn markers, so these can be larger than the buffer size +without causing problems; otherwise a 64K buffer would be needed in the worst +case.) + +The JPEG marker writer currently does *not* cope with suspension. +We feel that this is not necessary; it is much easier simply to require +the application to ensure there is enough buffer space before starting. (An +empty 2K buffer is more than sufficient for the header markers; and ensuring +there are a dozen or two bytes available before calling jpeg_finish_compress() +will suffice for the trailer.) This would not work for writing multi-scan +JPEG files, but we simply do not intend to support that capability with +suspension. + + +*** Memory manager services *** + +The JPEG library's memory manager controls allocation and deallocation of +memory, and it manages large "virtual" data arrays on machines where the +operating system does not provide virtual memory. Note that the same +memory manager serves both compression and decompression operations. + +In all cases, allocated objects are tied to a particular compression or +decompression master record, and they will be released when that master +record is destroyed. + +The memory manager does not provide explicit deallocation of objects. +Instead, objects are created in "pools" of free storage, and a whole pool +can be freed at once. This approach helps prevent storage-leak bugs, and +it speeds up operations whenever malloc/free are slow (as they often are). +The pools can be regarded as lifetime identifiers for objects. Two +pools/lifetimes are defined: + * JPOOL_PERMANENT lasts until master record is destroyed + * JPOOL_IMAGE lasts until done with image (JPEG datastream) +Permanent lifetime is used for parameters and tables that should be carried +across from one datastream to another; this includes all application-visible +parameters. Image lifetime is used for everything else. (A third lifetime, +JPOOL_PASS = one processing pass, was originally planned. However it was +dropped as not being worthwhile. The actual usage patterns are such that the +peak memory usage would be about the same anyway; and having per-pass storage +substantially complicates the virtual memory allocation rules --- see below.) + +The memory manager deals with three kinds of object: +1. "Small" objects. Typically these require no more than 10K-20K total. +2. "Large" objects. These may require tens to hundreds of K depending on + image size. Semantically they behave the same as small objects, but we + distinguish them for two reasons: + * On MS-DOS machines, large objects are referenced by FAR pointers, + small objects by NEAR pointers. + * Pool allocation heuristics may differ for large and small objects. + Note that individual "large" objects cannot exceed the size allowed by + type size_t, which may be 64K or less on some machines. +3. "Virtual" objects. These are large 2-D arrays of JSAMPLEs or JBLOCKs + (typically large enough for the entire image being processed). The + memory manager provides stripwise access to these arrays. On machines + without virtual memory, the rest of the array may be swapped out to a + temporary file. + +(Note: JSAMPARRAY and JBLOCKARRAY data structures are a combination of large +objects for the data proper and small objects for the row pointers. For +convenience and speed, the memory manager provides single routines to create +these structures. Similarly, virtual arrays include a small control block +and a JSAMPARRAY or JBLOCKARRAY working buffer, all created with one call.) + +In the present implementation, virtual arrays are only permitted to have image +lifespan. (Permanent lifespan would not be reasonable, and pass lifespan is +not very useful since a virtual array's raison d'etre is to store data for +multiple passes through the image.) We also expect that only "small" objects +will be given permanent lifespan, though this restriction is not required by +the memory manager. + +In a non-virtual-memory machine, some performance benefit can be gained by +making the in-memory buffers for virtual arrays be as large as possible. +(For small images, the buffers might fit entirely in memory, so blind +swapping would be very wasteful.) The memory manager will adjust the height +of the buffers to fit within a prespecified maximum memory usage. In order +to do this in a reasonably optimal fashion, the manager needs to allocate all +of the virtual arrays at once. Therefore, there isn't a one-step allocation +routine for virtual arrays; instead, there is a "request" routine that simply +allocates the control block, and a "realize" routine (called just once) that +determines space allocation and creates all of the actual buffers. The +realize routine must allow for space occupied by non-virtual large objects. +(We don't bother to factor in the space needed for small objects, on the +grounds that it isn't worth the trouble.) + +To support all this, we establish the following protocol for doing business +with the memory manager: + 1. Modules must request virtual arrays (which may have only image lifespan) + during the initial setup phase, i.e., in their jinit_xxx routines. + 2. All "large" objects (including JSAMPARRAYs and JBLOCKARRAYs) must also be + allocated during initial setup. + 3. realize_virt_arrays will be called at the completion of initial setup. + The above conventions ensure that sufficient information is available + for it to choose a good size for virtual array buffers. +Small objects of any lifespan may be allocated at any time. We expect that +the total space used for small objects will be small enough to be negligible +in the realize_virt_arrays computation. + +In a virtual-memory machine, we simply pretend that the available space is +infinite, thus causing realize_virt_arrays to decide that it can allocate all +the virtual arrays as full-size in-memory buffers. The overhead of the +virtual-array access protocol is very small when no swapping occurs. + +A virtual array can be specified to be "pre-zeroed"; when this flag is set, +never-yet-written sections of the array are set to zero before being made +available to the caller. If this flag is not set, never-written sections +of the array contain garbage. (This feature exists primarily because the +equivalent logic would otherwise be needed in jdcoefct.c for progressive +JPEG mode; we may as well make it available for possible other uses.) + +The first write pass on a virtual array is required to occur in top-to-bottom +order; read passes, as well as any write passes after the first one, may +access the array in any order. This restriction exists partly to simplify +the virtual array control logic, and partly because some file systems may not +support seeking beyond the current end-of-file in a temporary file. The main +implication of this restriction is that rearrangement of rows (such as +converting top-to-bottom data order to bottom-to-top) must be handled while +reading data out of the virtual array, not while putting it in. + + +*** Memory manager internal structure *** + +To isolate system dependencies as much as possible, we have broken the +memory manager into two parts. There is a reasonably system-independent +"front end" (jmemmgr.c) and a "back end" that contains only the code +likely to change across systems. All of the memory management methods +outlined above are implemented by the front end. The back end provides +the following routines for use by the front end (none of these routines +are known to the rest of the JPEG code): + +jpeg_mem_init, jpeg_mem_term system-dependent initialization/shutdown + +jpeg_get_small, jpeg_free_small interface to malloc and free library routines + (or their equivalents) + +jpeg_get_large, jpeg_free_large interface to FAR malloc/free in MSDOS machines; + else usually the same as + jpeg_get_small/jpeg_free_small + +jpeg_mem_available estimate available memory + +jpeg_open_backing_store create a backing-store object + +read_backing_store, manipulate a backing-store object +write_backing_store, +close_backing_store + +On some systems there will be more than one type of backing-store object +(specifically, in MS-DOS a backing store file might be an area of extended +memory as well as a disk file). jpeg_open_backing_store is responsible for +choosing how to implement a given object. The read/write/close routines +are method pointers in the structure that describes a given object; this +lets them be different for different object types. + +It may be necessary to ensure that backing store objects are explicitly +released upon abnormal program termination. For example, MS-DOS won't free +extended memory by itself. To support this, we will expect the main program +or surrounding application to arrange to call self_destruct (typically via +jpeg_destroy) upon abnormal termination. This may require a SIGINT signal +handler or equivalent. We don't want to have the back end module install its +own signal handler, because that would pre-empt the surrounding application's +ability to control signal handling. + +The IJG distribution includes several memory manager back end implementations. +Usually the same back end should be suitable for all applications on a given +system, but it is possible for an application to supply its own back end at +need. + + +*** Implications of DNL marker *** + +Some JPEG files may use a DNL marker to postpone definition of the image +height (this would be useful for a fax-like scanner's output, for instance). +In these files the SOF marker claims the image height is 0, and you only +find out the true image height at the end of the first scan. + +We could read these files as follows: +1. Upon seeing zero image height, replace it by 65535 (the maximum allowed). +2. When the DNL is found, update the image height in the global image + descriptor. +This implies that control modules must avoid making copies of the image +height, and must re-test for termination after each MCU row. This would +be easy enough to do. + +In cases where image-size data structures are allocated, this approach will +result in very inefficient use of virtual memory or much-larger-than-necessary +temporary files. This seems acceptable for something that probably won't be a +mainstream usage. People might have to forgo use of memory-hogging options +(such as two-pass color quantization or noninterleaved JPEG files) if they +want efficient conversion of such files. (One could improve efficiency by +demanding a user-supplied upper bound for the height, less than 65536; in most +cases it could be much less.) + +The standard also permits the SOF marker to overestimate the image height, +with a DNL to give the true, smaller height at the end of the first scan. +This would solve the space problems if the overestimate wasn't too great. +However, it implies that you don't even know whether DNL will be used. + +This leads to a couple of very serious objections: +1. Testing for a DNL marker must occur in the inner loop of the decompressor's + Huffman decoder; this implies a speed penalty whether the feature is used + or not. +2. There is no way to hide the last-minute change in image height from an + application using the decoder. Thus *every* application using the IJG + library would suffer a complexity penalty whether it cared about DNL or + not. +We currently do not support DNL because of these problems. + +A different approach is to insist that DNL-using files be preprocessed by a +separate program that reads ahead to the DNL, then goes back and fixes the SOF +marker. This is a much simpler solution and is probably far more efficient. +Even if one wants piped input, buffering the first scan of the JPEG file needs +a lot smaller temp file than is implied by the maximum-height method. For +this approach we'd simply treat DNL as a no-op in the decompressor (at most, +check that it matches the SOF image height). + +We will not worry about making the compressor capable of outputting DNL. +Something similar to the first scheme above could be applied if anyone ever +wants to make that work. diff --git a/project/jni/sdl2_image/external/jpeg-9b/testimg.bmp

/* to declare isdigit() */ + + +#if TRANSFORMS_SUPPORTED + +/* + * Lossless image transformation routines. These routines work on DCT + * coefficient arrays and thus do not require any lossy decompression + * or recompression of the image. + * Thanks to Guido Vollbeding for the initial design and code of this feature, + * and to Ben Jackson for introducing the cropping feature. + * + * Horizontal flipping is done in-place, using a single top-to-bottom + * pass through the virtual source array. It will thus be much the + * fastest option for images larger than main memory. + * + * The other routines require a set of destination virtual arrays, so they + * need twice as much memory as jpegtran normally does. The destination + * arrays are always written in normal scan order (top to bottom) because + * the virtual array manager expects this. The source arrays will be scanned + * in the corresponding order, which means multiple passes through the source + * arrays for most of the transforms. That could result in much thrashing + * if the image is larger than main memory. + * + * If cropping or trimming is involved, the destination arrays may be smaller + * than the source arrays. Note it is not possible to do horizontal flip + * in-place when a nonzero Y crop offset is specified, since we'd have to move + * data from one block row to another but the virtual array manager doesn't + * guarantee we can touch more than one row at a time. So in that case, + * we have to use a separate destination array. + * + * Some notes about the operating environment of the individual transform + * routines: + * 1. Both the source and destination virtual arrays are allocated from the + * source JPEG object, and therefore should be manipulated by calling the + * source's memory manager. + * 2. The destination's component count should be used. It may be smaller + * than the source's when forcing to grayscale. + * 3. Likewise the destination's sampling factors should be used. When + * forcing to grayscale the destination's sampling factors will be all 1, + * and we may as well take that as the effective iMCU size. + * 4. When "trim" is in effect, the destination's dimensions will be the + * trimmed values but the source's will be untrimmed. + * 5. When "crop" is in effect, the destination's dimensions will be the + * cropped values but the source's will be uncropped. Each transform + * routine is responsible for picking up source data starting at the + * correct X and Y offset for the crop region. (The X and Y offsets + * passed to the transform routines are measured in iMCU blocks of the + * destination.) + * 6. All the routines assume that the source and destination buffers are + * padded out to a full iMCU boundary.

The right and bottom + * image edges are padded out to the next iMCU boundary with junk data; but + * no padding is possible at the top and left edges. If we were to flip + * the whole image including the pad data, then pad garbage would become + * visible at the top and/or left, and real pixels would disappear into the + * pad margins --- perhaps permanently, since encoders & decoders may not + * bother to preserve DCT blocks that appear to be completely outside the + * nominal image area. So, we have to exclude any partial iMCUs from the + * basic transformation. + * + * Transpose is the only transformation that can handle partial iMCUs at the + * right and bottom edges completely cleanly. flip_h can flip partial iMCUs + * at the bottom, but leaves any partial iMCUs at the right edge untouched. + * Similarly flip_v leaves any partial iMCUs at the bottom edge untouched. + * The other transforms are defined as combinations of these basic transforms + * and process edge blocks in a way that preserves the equivalence. + * + * The "trim" option causes untransformable partial iMCUs to be dropped; + * this is not strictly lossless, but it usually gives the best-looking + * result for odd-size images. Note that when this option is active, + * the expected mathematical equivalences between the transforms may not hold. + * (For example, -rot 270 -trim trims only the bottom edge, but -rot 90 -trim + * followed by -rot 180 -trim trims both edges.) + * + * We also offer a lossless-crop option, which discards data outside a given + * image region but losslessly preserves what is inside. Like the rotate and + * flip transforms, lossless crop is restricted by the current JPEG format: the + * upper left corner of the selected region must fall on an iMCU boundary. If + * this does not hold for the given crop parameters, we silently move the upper + * left corner up and/or left to make it so, simultaneously increasing the + * region dimensions to keep the lower right crop corner unchanged. (Thus, the + * output image covers at least the requested region, but may cover more.) + * The adjustment of the region dimensions may be optionally disabled. + * + * A complementary lossless-wipe option is provided to discard (gray out) data + * inside a given image region while losslessly preserving what is outside. + * + * We also provide a lossless-resize option, which is kind of a lossless-crop + * operation in the DCT coefficient block domain - it discards higher-order + * coefficients and losslessly preserves lower-order coefficients of a + * sub-block. + * + * Rotate/flip transform, resize, and crop can be requested together in a + * single invocation.

(See +the other documentation files if you wish to use the JPEG library within +your own programs.) + +If you are on a Unix machine you may prefer to read the Unix-style manual +pages in files cjpeg.1, djpeg.1, jpegtran.1, rdjpgcom.1, wrjpgcom.1. + + +INTRODUCTION + +These programs implement JPEG image encoding, decoding, and transcoding. +JPEG (pronounced "jay-peg") is a standardized compression method for +full-color and grayscale images. + + +GENERAL USAGE + +We provide two programs, cjpeg to compress an image file into JPEG format, +and djpeg to decompress a JPEG file back into a conventional image format. + +On Unix-like systems, you say: + cjpeg [switches] [imagefile] >jpegfile +or + djpeg [switches] [jpegfile] >imagefile +The programs read the specified input file, or standard input if none is +named. They always write to standard output (with trace/error messages to +standard error). These conventions are handy for piping images between +programs. + +On most non-Unix systems, you say: + cjpeg [switches] imagefile jpegfile +or + djpeg [switches] jpegfile imagefile +i.e., both the input and output files are named on the command line. This +style is a little more foolproof, and it loses no functionality if you don't +have pipes. (You can get this style on Unix too, if you prefer, by defining +TWO_FILE_COMMANDLINE when you compile the programs; see install.txt.) + +You can also say: + cjpeg [switches] -outfile jpegfile imagefile +or + djpeg [switches] -outfile imagefile jpegfile +This syntax works on all systems, so it is useful for scripts. + +The currently supported image file formats are: PPM (PBMPLUS color format), +PGM (PBMPLUS grayscale format), BMP, Targa, and RLE (Utah Raster Toolkit +format). (RLE is supported only if the URT library is available, which it +isn't on most non-Unix systems.) cjpeg recognizes the input image format +automatically, with the exception of some Targa-format files. You have to +tell djpeg which format to generate. + +JPEG files are in the standard JFIF file format. There are other, +less widely used JPEG-based file formats, but we don't support them. + +All switch names may be abbreviated; for example, -grayscale may be written +-gray or -gr. Most of the "basic" switches can be abbreviated to as little as +one letter. Upper and lower case are equivalent (-BMP is the same as -bmp). +British spellings are also accepted (e.g., -greyscale), though for brevity +these are not mentioned below. + + +CJPEG DETAILS + +The basic command line switches for cjpeg are: + + -quality N[,...] Scale quantization tables to adjust image quality. + Quality is 0 (worst) to 100 (best); default is 75. + (See below for more info.) + + -grayscale Create monochrome JPEG file from color input. + Be sure to use this switch when compressing a grayscale + BMP file, because cjpeg isn't bright enough to notice + whether a BMP file uses only shades of gray. By + saying -grayscale, you'll get a smaller JPEG file that + takes less time to process. + + -rgb Create RGB JPEG file. + Using this switch suppresses the conversion from RGB + colorspace input to the default YCbCr JPEG colorspace. + You can use this switch in combination with the + -block N switch (see below) for lossless JPEG coding. + See also the -rgb1 switch below. + + -optimize Perform optimization of entropy encoding parameters. + Without this, default encoding parameters are used. + -optimize usually makes the JPEG file a little smaller, + but cjpeg runs somewhat slower and needs much more + memory. Image quality and speed of decompression are + unaffected by -optimize. + + -progressive Create progressive JPEG file (see below). + + -scale M/N Scale the output image by a factor M/N. Currently + supported scale factors are M/N with all N from 1 to + 16, where M is the destination DCT size, which is 8 by + default (see -block N switch below). + + -targa Input file is Targa format. Targa files that contain + an "identification" field will not be automatically + recognized by cjpeg; for such files you must specify + -targa to make cjpeg treat the input as Targa format. + For most Targa files, you won't need this switch. + +The -quality switch lets you trade off compressed file size against quality of +the reconstructed image: the higher the quality setting, the larger the JPEG +file, and the closer the output image will be to the original input. Normally +you want to use the lowest quality setting (smallest file) that decompresses +into something visually indistinguishable from the original image. For this +purpose the quality setting should be between 50 and 95; the default of 75 is +often about right. If you see defects at -quality 75, then go up 5 or 10 +counts at a time until you are happy with the output image. (The optimal +setting will vary from one image to another.) + +-quality 100 will generate a quantization table of all 1's, minimizing loss +in the quantization step (but there is still information loss in subsampling, +as well as roundoff error). This setting is mainly of interest for +experimental purposes. Quality values above about 95 are NOT recommended for +normal use; the compressed file size goes up dramatically for hardly any gain +in output image quality. + +In the other direction, quality values below 50 will produce very small files +of low image quality. Settings around 5 to 10 might be useful in preparing an +index of a large image library, for example. Try -quality 2 (or so) for some +amusing Cubist effects. (Note: quality values below about 25 generate 2-byte +quantization tables, which are considered optional in the JPEG standard. +cjpeg emits a warning message when you give such a quality value, because some +other JPEG programs may be unable to decode the resulting file. Use -baseline +if you need to ensure compatibility at low quality values.) + +The -quality option has been extended in IJG version 7 for support of separate +quality settings for luminance and chrominance (or in general, for every +provided quantization table slot). This feature is useful for high-quality +applications which cannot accept the damage of color data by coarse +subsampling settings. You can now easily reduce the color data amount more +smoothly with finer control without separate subsampling. The resulting file +is fully compliant with standard JPEG decoders. +Note that the -quality ratings refer to the quantization table slots, and that +the last value is replicated if there are more q-table slots than parameters. +The default q-table slots are 0 for luminance and 1 for chrominance with +default tables as given in the JPEG standard. This is compatible with the old +behaviour in case that only one parameter is given, which is then used for +both luminance and chrominance (slots 0 and 1). More or custom quantization +tables can be set with -qtables and assigned to components with -qslots +parameter (see the "wizard" switches below). +CAUTION: You must explicitly add -sample 1x1 for efficient separate color +quality selection, since the default value used by library is 2x2! + +The -progressive switch creates a "progressive JPEG" file. In this type of +JPEG file, the data is stored in multiple scans of increasing quality. If the +file is being transmitted over a slow communications link, the decoder can use +the first scan to display a low-quality image very quickly, and can then +improve the display with each subsequent scan. The final image is exactly +equivalent to a standard JPEG file of the same quality setting, and the total +file size is about the same --- often a little smaller. + +Switches for advanced users: + + -arithmetic Use arithmetic coding. + CAUTION: arithmetic coded JPEG is not yet widely + implemented, so many decoders will be unable to + view an arithmetic coded JPEG file at all. + + -block N Set DCT block size. All N from 1 to 16 are possible. + Default is 8 (baseline format). + Larger values produce higher compression, + smaller values produce higher quality + (exact DCT stage possible with 1 or 2; with the + default quality of 75 and default Luminance qtable + the DCT+Quantization stage is lossless for N=1). + CAUTION: An implementation of the JPEG SmartScale + extension is required for this feature. SmartScale + enabled JPEG is not yet widely implemented, so many + decoders will be unable to view a SmartScale extended + JPEG file at all. + + -rgb1 Create RGB JPEG file with reversible color transform. + Works like the -rgb switch (see above) and inserts a + simple reversible color transform into the processing + which significantly improves the compression. + Use this switch in combination with the -block N + switch (see above) for lossless JPEG coding. + CAUTION: A decoder with inverse color transform + support is required for this feature. Reversible + color transform support is not yet widely implemented, + so many decoders will be unable to view a reversible + color transformed JPEG file at all. + + -bgycc Create big gamut YCC JPEG file. + In this type of encoding the color difference + components are quantized further by a factor of 2 + compared to the normal Cb/Cr values, thus creating + space to allow larger color values with higher + saturation than the normal gamut limits to be encoded. + In order to compensate for the loss of color fidelity + compared to a normal YCC encoded file, the color + quantization tables can be adjusted accordingly. + For example, cjpeg -bgycc -quality 80,90 will give + similar results as cjpeg -quality 80. + CAUTION: For correct decompression a decoder with big + gamut YCC support (JFIF version 2) is required. + An old decoder may or may not display a big gamut YCC + encoded JPEG file, depending on JFIF version check + and corresponding warning/error configuration. + In case of a granted decompression the old decoder + will display the image with half saturated colors. + + -dct int Use integer DCT method (default). + -dct fast Use fast integer DCT (less accurate). + -dct float Use floating-point DCT method. + The float method is very slightly more accurate than + the int method, but is much slower unless your machine + has very fast floating-point hardware. Also note that + results of the floating-point method may vary slightly + across machines, while the integer methods should give + the same results everywhere. The fast integer method + is much less accurate than the other two. + + -nosmooth Don't use high-quality downsampling. + + -restart N Emit a JPEG restart marker every N MCU rows, or every + N MCU blocks if "B" is attached to the number. + -restart 0 (the default) means no restart markers. + + -smooth N Smooth the input image to eliminate dithering noise. + N, ranging from 1 to 100, indicates the strength of + smoothing. 0 (the default) means no smoothing. + + -maxmemory N Set limit for amount of memory to use in processing + large images. Value is in thousands of bytes, or + millions of bytes if "M" is attached to the number. + For example, -max 4m selects 4000000 bytes. If more + space is needed, temporary files will be used. + + -verbose Enable debug printout. More -v's give more printout. + or -debug Also, version information is printed at startup. + +The -restart option inserts extra markers that allow a JPEG decoder to +resynchronize after a transmission error. Without restart markers, any damage +to a compressed file will usually ruin the image from the point of the error +to the end of the image; with restart markers, the damage is usually confined +to the portion of the image up to the next restart marker. Of course, the +restart markers occupy extra space. We recommend -restart 1 for images that +will be transmitted across unreliable networks such as Usenet. + +The -smooth option filters the input to eliminate fine-scale noise. This is +often useful when converting dithered images to JPEG: a moderate smoothing +factor of 10 to 50 gets rid of dithering patterns in the input file, resulting +in a smaller JPEG file and a better-looking image. Too large a smoothing +factor will visibly blur the image, however. + +Switches for wizards: + + -baseline Force baseline-compatible quantization tables to be + generated. This clamps quantization values to 8 bits + even at low quality settings. (This switch is poorly + named, since it does not ensure that the output is + actually baseline JPEG. For example, you can use + -baseline and -progressive together.) + + -qtables file Use the quantization tables given in the specified + text file. + + -qslots N[,...] Select which quantization table to use for each color + component. + + -sample HxV[,...] Set JPEG sampling factors for each color component. + + -scans file Use the scan script given in the specified text file. + +The "wizard" switches are intended for experimentation with JPEG. If you +don't know what you are doing, DON'T USE THEM. These switches are documented +further in the file wizard.txt. + + +DJPEG DETAILS + +The basic command line switches for djpeg are: + + -colors N Reduce image to at most N colors. This reduces the + or -quantize N number of colors used in the output image, so that it + can be displayed on a colormapped display or stored in + a colormapped file format. For example, if you have + an 8-bit display, you'd need to reduce to 256 or fewer + colors. (-colors is the recommended name, -quantize + is provided only for backwards compatibility.) + + -fast Select recommended processing options for fast, low + quality output. (The default options are chosen for + highest quality output.) Currently, this is equivalent + to "-dct fast -nosmooth -onepass -dither ordered". + + -grayscale Force grayscale output even if JPEG file is color. + Useful for viewing on monochrome displays; also, + djpeg runs noticeably faster in this mode. + + -rgb Force RGB output even if JPEG file is grayscale. + This is provided to support applications that don't + want to cope with grayscale as a separate case. + + -scale M/N Scale the output image by a factor M/N. Currently + supported scale factors are M/N with all M from 1 to + 16, where N is the source DCT size, which is 8 for + baseline JPEG. If the /N part is omitted, then M + specifies the DCT scaled size to be applied on the + given input. For baseline JPEG this is equivalent to + M/8 scaling, since the source DCT size for baseline + JPEG is 8. Scaling is handy if the image is larger + than your screen; also, djpeg runs much faster when + scaling down the output. + + -bmp Select BMP output format (Windows flavor). 8-bit + colormapped format is emitted if -colors or -grayscale + is specified, or if the JPEG file is grayscale; + otherwise, 24-bit full-color format is emitted. + + -gif Select GIF output format. Since GIF does not support + more than 256 colors, -colors 256 is assumed (unless + you specify a smaller number of colors). If you + specify -fast, the default number of colors is 216. + + -os2 Select BMP output format (OS/2 1.x flavor). 8-bit + colormapped format is emitted if -colors or -grayscale + is specified, or if the JPEG file is grayscale; + otherwise, 24-bit full-color format is emitted. + + -pnm Select PBMPLUS (PPM/PGM) output format (this is the + default format). PGM is emitted if the JPEG file is + grayscale or if -grayscale is specified; otherwise + PPM is emitted. + + -rle Select RLE output format. (Requires URT library.) + + -targa Select Targa output format. Grayscale format is + emitted if the JPEG file is grayscale or if + -grayscale is specified; otherwise, colormapped format + is emitted if -colors is specified; otherwise, 24-bit + full-color format is emitted. + +Switches for advanced users: + + -dct int Use integer DCT method (default). + -dct fast Use fast integer DCT (less accurate). + -dct float Use floating-point DCT method. + The float method is very slightly more accurate than + the int method, but is much slower unless your machine + has very fast floating-point hardware. Also note that + results of the floating-point method may vary slightly + across machines, while the integer methods should give + the same results everywhere. The fast integer method + is much less accurate than the other two. + + -dither fs Use Floyd-Steinberg dithering in color quantization. + -dither ordered Use ordered dithering in color quantization. + -dither none Do not use dithering in color quantization. + By default, Floyd-Steinberg dithering is applied when + quantizing colors; this is slow but usually produces + the best results. Ordered dither is a compromise + between speed and quality; no dithering is fast but + usually looks awful. Note that these switches have + no effect unless color quantization is being done. + Ordered dither is only available in -onepass mode. + + -map FILE Quantize to the colors used in the specified image + file. This is useful for producing multiple files + with identical color maps, or for forcing a predefined + set of colors to be used. The FILE must be a GIF + or PPM file. This option overrides -colors and + -onepass. + + -nosmooth Don't use high-quality upsampling. + + -onepass Use one-pass instead of two-pass color quantization. + The one-pass method is faster and needs less memory, + but it produces a lower-quality image. -onepass is + ignored unless you also say -colors N. Also, + the one-pass method is always used for grayscale + output (the two-pass method is no improvement then). + + -maxmemory N Set limit for amount of memory to use in processing + large images. Value is in thousands of bytes, or + millions of bytes if "M" is attached to the number. + For example, -max 4m selects 4000000 bytes. If more + space is needed, temporary files will be used. + + -verbose Enable debug printout. More -v's give more printout. + or -debug Also, version information is printed at startup. + + +HINTS FOR CJPEG + +Color GIF files are not the ideal input for JPEG; JPEG is really intended for +compressing full-color (24-bit) images. In particular, don't try to convert +cartoons, line drawings, and other images that have only a few distinct +colors. GIF works great on these, JPEG does not. If you want to convert a +GIF to JPEG, you should experiment with cjpeg's -quality and -smooth options +to get a satisfactory conversion. -smooth 10 or so is often helpful. + +Avoid running an image through a series of JPEG compression/decompression +cycles. Image quality loss will accumulate; after ten or so cycles the image +may be noticeably worse than it was after one cycle. It's best to use a +lossless format while manipulating an image, then convert to JPEG format when +you are ready to file the image away. + +The -optimize option to cjpeg is worth using when you are making a "final" +version for posting or archiving. It's also a win when you are using low +quality settings to make very small JPEG files; the percentage improvement +is often a lot more than it is on larger files. (At present, -optimize +mode is always selected when generating progressive JPEG files.) + +GIF input files are no longer supported, to avoid the Unisys LZW patent +(now expired). +(Conversion of GIF files to JPEG is usually a bad idea anyway.) + + +HINTS FOR DJPEG + +To get a quick preview of an image, use the -grayscale and/or -scale switches. +"-grayscale -scale 1/8" is the fastest case. + +Several options are available that trade off image quality to gain speed. +"-fast" turns on the recommended settings. + +"-dct fast" and/or "-nosmooth" gain speed at a small sacrifice in quality. +When producing a color-quantized image, "-onepass -dither ordered" is fast but +much lower quality than the default behavior. "-dither none" may give +acceptable results in two-pass mode, but is seldom tolerable in one-pass mode. + +If you are fortunate enough to have very fast floating point hardware, +"-dct float" may be even faster than "-dct fast". But on most machines +"-dct float" is slower than "-dct int"; in this case it is not worth using, +because its theoretical accuracy advantage is too small to be significant +in practice. + +Two-pass color quantization requires a good deal of memory; on MS-DOS machines +it may run out of memory even with -maxmemory 0. In that case you can still +decompress, with some loss of image quality, by specifying -onepass for +one-pass quantization. + +To avoid the Unisys LZW patent (now expired), djpeg produces uncompressed GIF +files. These are larger than they should be, but are readable by standard GIF +decoders. + + +HINTS FOR BOTH PROGRAMS + +If more space is needed than will fit in the available main memory (as +determined by -maxmemory), temporary files will be used. (MS-DOS versions +will try to get extended or expanded memory first.) The temporary files are +often rather large: in typical cases they occupy three bytes per pixel, for +example 3*800*600 = 1.44Mb for an 800x600 image. If you don't have enough +free disk space, leave out -progressive and -optimize (for cjpeg) or specify +-onepass (for djpeg). + +On MS-DOS, the temporary files are created in the directory named by the TMP +or TEMP environment variable, or in the current directory if neither of those +exist. Amiga implementations put the temp files in the directory named by +JPEGTMP:, so be sure to assign JPEGTMP: to a disk partition with adequate free +space. + +The default memory usage limit (-maxmemory) is set when the software is +compiled. If you get an "insufficient memory" error, try specifying a smaller +-maxmemory value, even -maxmemory 0 to use the absolute minimum space. You +may want to recompile with a smaller default value if this happens often. + +On machines that have "environment" variables, you can define the environment +variable JPEGMEM to set the default memory limit. The value is specified as +described for the -maxmemory switch. JPEGMEM overrides the default value +specified when the program was compiled, and itself is overridden by an +explicit -maxmemory switch. + +On MS-DOS machines, -maxmemory is the amount of main (conventional) memory to +use. (Extended or expanded memory is also used if available.) Most +DOS-specific versions of this software do their own memory space estimation +and do not need you to specify -maxmemory. + + +JPEGTRAN + +jpegtran performs various useful transformations of JPEG files. +It can translate the coded representation from one variant of JPEG to another, +for example from baseline JPEG to progressive JPEG or vice versa. It can also +perform some rearrangements of the image data, for example turning an image +from landscape to portrait format by rotation. For EXIF files and JPEG files +containing Exif data, you may prefer to use exiftran instead. + +jpegtran works by rearranging the compressed data (DCT coefficients), without +ever fully decoding the image. Therefore, its transformations are lossless: +there is no image degradation at all, which would not be true if you used +djpeg followed by cjpeg to accomplish the same conversion. But by the same +token, jpegtran cannot perform lossy operations such as changing the image +quality. However, while the image data is losslessly transformed, metadata +can be removed. See the -copy option for specifics. + +jpegtran uses a command line syntax similar to cjpeg or djpeg. +On Unix-like systems, you say: + jpegtran [switches] [inputfile] >outputfile +On most non-Unix systems, you say: + jpegtran [switches] inputfile outputfile +where both the input and output files are JPEG files. + +To specify the coded JPEG representation used in the output file, +jpegtran accepts a subset of the switches recognized by cjpeg: + -optimize Perform optimization of entropy encoding parameters. + -progressive Create progressive JPEG file. + -arithmetic Use arithmetic coding. + -restart N Emit a JPEG restart marker every N MCU rows, or every + N MCU blocks if "B" is attached to the number. + -scans file Use the scan script given in the specified text file. +See the previous discussion of cjpeg for more details about these switches. +If you specify none of these switches, you get a plain baseline-JPEG output +file. The quality setting and so forth are determined by the input file. + +The image can be losslessly transformed by giving one of these switches: + -flip horizontal Mirror image horizontally (left-right). + -flip vertical Mirror image vertically (top-bottom). + -rotate 90 Rotate image 90 degrees clockwise. + -rotate 180 Rotate image 180 degrees. + -rotate 270 Rotate image 270 degrees clockwise (or 90 ccw). + -transpose Transpose image (across UL-to-LR axis). + -transverse Transverse transpose (across UR-to-LL axis). + +The transpose transformation has no restrictions regarding image dimensions. +The other transformations operate rather oddly if the image dimensions are not +a multiple of the iMCU size (usually 8 or 16 pixels), because they can only +transform complete blocks of DCT coefficient data in the desired way. + +jpegtran's default behavior when transforming an odd-size image is designed +to preserve exact reversibility and mathematical consistency of the +transformation set. As stated, transpose is able to flip the entire image +area. Horizontal mirroring leaves any partial iMCU column at the right edge +untouched, but is able to flip all rows of the image. Similarly, vertical +mirroring leaves any partial iMCU row at the bottom edge untouched, but is +able to flip all columns. The other transforms can be built up as sequences +of transpose and flip operations; for consistency, their actions on edge +pixels are defined to be the same as the end result of the corresponding +transpose-and-flip sequence. + +For practical use, you may prefer to discard any untransformable edge pixels +rather than having a strange-looking strip along the right and/or bottom edges +of a transformed image. To do this, add the -trim switch: + -trim Drop non-transformable edge blocks. +Obviously, a transformation with -trim is not reversible, so strictly speaking +jpegtran with this switch is not lossless. Also, the expected mathematical +equivalences between the transformations no longer hold. For example, +"-rot 270 -trim" trims only the bottom edge, but "-rot 90 -trim" followed by +"-rot 180 -trim" trims both edges. + +If you are only interested in perfect transformation, add the -perfect switch: + -perfect Fails with an error if the transformation is not + perfect. +For example you may want to do + jpegtran -rot 90 -perfect foo.jpg || djpeg foo.jpg | pnmflip -r90 | cjpeg +to do a perfect rotation if available or an approximated one if not. + +We also offer a lossless-crop option, which discards data outside a given +image region but losslessly preserves what is inside. Like the rotate and +flip transforms, lossless crop is restricted by the current JPEG format: the +upper left corner of the selected region must fall on an iMCU boundary. If +this does not hold for the given crop parameters, we silently move the upper +left corner up and/or left to make it so, simultaneously increasing the +region dimensions to keep the lower right crop corner unchanged. (Thus, the +output image covers at least the requested region, but may cover more.) +The adjustment of the region dimensions may be optionally disabled by +attaching an 'f' character ("force") to the width or height number. + +The image can be losslessly cropped by giving the switch: + -crop WxH+X+Y Crop to a rectangular subarea of width W, height H + starting at point X,Y. + +A complementary lossless-wipe option is provided to discard (gray out) data +inside a given image region while losslessly preserving what is outside: + -wipe WxH+X+Y Wipe (gray out) a rectangular subarea of + width W, height H starting at point X,Y. + +Other not-strictly-lossless transformation switches are: + + -grayscale Force grayscale output. +This option discards the chrominance channels if the input image is YCbCr +(ie, a standard color JPEG), resulting in a grayscale JPEG file. The +luminance channel is preserved exactly, so this is a better method of reducing +to grayscale than decompression, conversion, and recompression. This switch +is particularly handy for fixing a monochrome picture that was mistakenly +encoded as a color JPEG. (In such a case, the space savings from getting rid +of the near-empty chroma channels won't be large; but the decoding time for +a grayscale JPEG is substantially less than that for a color JPEG.) + + -scale M/N Scale the output image by a factor M/N. +Currently supported scale factors are M/N with all M from 1 to 16, where N is +the source DCT size, which is 8 for baseline JPEG. If the /N part is omitted, +then M specifies the DCT scaled size to be applied on the given input. For +baseline JPEG this is equivalent to M/8 scaling, since the source DCT size +for baseline JPEG is 8. CAUTION: An implementation of the JPEG SmartScale +extension is required for this feature. SmartScale enabled JPEG is not yet +widely implemented, so many decoders will be unable to view a SmartScale +extended JPEG file at all. + +jpegtran also recognizes these switches that control what to do with "extra" +markers, such as comment blocks: + -copy none Copy no extra markers from source file. + This setting suppresses all comments + and other metadata in the source file. + -copy comments Copy only comment markers. + This setting copies comments from the source file, + but discards any other metadata. + -copy all Copy all extra markers. This setting preserves + metadata found in the source file, such as JFIF + thumbnails, Exif data, and Photoshop settings. + In some files these extra markers can be sizable. + Note that this option will copy thumbnails as-is; + they will not be transformed. +The default behavior is -copy comments. (Note: in IJG releases v6 and v6a, +jpegtran always did the equivalent of -copy none.) + +Additional switches recognized by jpegtran are: + -outfile filename + -maxmemory N + -verbose + -debug +These work the same as in cjpeg or djpeg. + + +THE COMMENT UTILITIES + +The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file. +Although the standard doesn't actually define what COM blocks are for, they +are widely used to hold user-supplied text strings. This lets you add +annotations, titles, index terms, etc to your JPEG files, and later retrieve +them as text. COM blocks do not interfere with the image stored in the JPEG +file. The maximum size of a COM block is 64K, but you can have as many of +them as you like in one JPEG file. + +We provide two utility programs to display COM block contents and add COM +blocks to a JPEG file. + +rdjpgcom searches a JPEG file and prints the contents of any COM blocks on +standard output. The command line syntax is + rdjpgcom [-raw] [-verbose] [inputfilename] +The switch "-raw" (or just "-r") causes rdjpgcom to also output non-printable +characters in comments, which are normally escaped for security reasons. +The switch "-verbose" (or just "-v") causes rdjpgcom to also display the JPEG +image dimensions. If you omit the input file name from the command line, +the JPEG file is read from standard input. (This may not work on some +operating systems, if binary data can't be read from stdin.) + +wrjpgcom adds a COM block, containing text you provide, to a JPEG file. +Ordinarily, the COM block is added after any existing COM blocks, but you +can delete the old COM blocks if you wish. wrjpgcom produces a new JPEG +file; it does not modify the input file. DO NOT try to overwrite the input +file by directing wrjpgcom's output back into it; on most systems this will +just destroy your file. + +The command line syntax for wrjpgcom is similar to cjpeg's. On Unix-like +systems, it is + wrjpgcom [switches] [inputfilename] +The output file is written to standard output. The input file comes from +the named file, or from standard input if no input file is named. + +On most non-Unix systems, the syntax is + wrjpgcom [switches] inputfilename outputfilename +where both input and output file names must be given explicitly. + +wrjpgcom understands three switches: + -replace Delete any existing COM blocks from the file. + -comment "Comment text" Supply new COM text on command line. + -cfile name Read text for new COM block from named file. +(Switch names can be abbreviated.) If you have only one line of comment text +to add, you can provide it on the command line with -comment. The comment +text must be surrounded with quotes so that it is treated as a single +argument. Longer comments can be read from a text file. + +If you give neither -comment nor -cfile, then wrjpgcom will read the comment +text from standard input. (In this case an input image file name MUST be +supplied, so that the source JPEG file comes from somewhere else.) You can +enter multiple lines, up to 64KB worth. Type an end-of-file indicator +(usually control-D or control-Z) to terminate the comment text entry. + +wrjpgcom will not add a COM block if the provided comment string is empty. +Therefore -replace -comment "" can be used to delete all COM blocks from a +file. + +These utility programs do not depend on the IJG JPEG library. In +particular, the source code for rdjpgcom is intended as an illustration of +the minimum amount of code required to parse a JPEG file header correctly. diff --git a/project/jni/sdl2_image/external/jpeg-9b/wizard.txt b/project/jni/sdl2_image/external/jpeg-9b/wizard.txt new file mode 100644 index 000000000..54170b227 --- /dev/null +++ b/project/jni/sdl2_image/external/jpeg-9b/wizard.txt @@ -0,0 +1,211 @@ +Advanced usage instructions for the Independent JPEG Group's JPEG software +========================================================================== + +This file describes cjpeg's "switches for wizards". + +The "wizard" switches are intended for experimentation with JPEG by persons +who are reasonably knowledgeable about the JPEG standard. If you don't know +what you are doing, DON'T USE THESE SWITCHES. You'll likely produce files +with worse image quality and/or poorer compression than you'd get from the +default settings. Furthermore, these switches must be used with caution +when making files intended for general use, because not all JPEG decoders +will support unusual JPEG parameter settings. + + +Quantization Table Adjustment +----------------------------- + +Ordinarily, cjpeg starts with a default set of tables (the same ones given +as examples in the JPEG standard) and scales them up or down according to +the -quality setting. The details of the scaling algorithm can be found in +jcparam.c. At very low quality settings, some quantization table entries +can get scaled up to values exceeding 255. Although 2-byte quantization +values are supported by the IJG software, this feature is not in baseline +JPEG and is not supported by all implementations. If you need to ensure +wide compatibility of low-quality files, you can constrain the scaled +quantization values to no more than 255 by giving the -baseline switch. +Note that use of -baseline will result in poorer quality for the same file +size, since more bits than necessary are expended on higher AC coefficients. + +You can substitute a different set of quantization values by using the +-qtables switch: + + -qtables file Use the quantization tables given in the named file. + +The specified file should be a text file containing decimal quantization +values. The file should contain one to four tables, each of 64 elements. +The tables are implicitly numbered 0,1,etc. in order of appearance. Table +entries appear in normal array order (NOT in the zigzag order in which they +will be stored in the JPEG file). + +Quantization table files are free format, in that arbitrary whitespace can +appear between numbers. Also, comments can be included: a comment starts +with '#' and extends to the end of the line. Here is an example file that +duplicates the default quantization tables: + + # Quantization tables given in JPEG spec, section K.1 + + # This is table 0 (the luminance table): + 16 11 10 16 24 40 51 61 + 12 12 14 19 26 58 60 55 + 14 13 16 24 40 57 69 56 + 14 17 22 29 51 87 80 62 + 18 22 37 56 68 109 103 77 + 24 35 55 64 81 104 113 92 + 49 64 78 87 103 121 120 101 + 72 92 95 98 112 100 103 99 + + # This is table 1 (the chrominance table): + 17 18 24 47 99 99 99 99 + 18 21 26 66 99 99 99 99 + 24 26 56 99 99 99 99 99 + 47 66 99 99 99 99 99 99 + 99 99 99 99 99 99 99 99 + 99 99 99 99 99 99 99 99 + 99 99 99 99 99 99 99 99 + 99 99 99 99 99 99 99 99 + +If the -qtables switch is used without -quality, then the specified tables +are used exactly as-is. If both -qtables and -quality are used, then the +tables taken from the file are scaled in the same fashion that the default +tables would be scaled for that quality setting. If -baseline appears, then +the quantization values are constrained to the range 1-255. + +By default, cjpeg will use quantization table 0 for luminance components and +table 1 for chrominance components. To override this choice, use the -qslots +switch: + + -qslots N[,...] Select which quantization table to use for + each color component. + +The -qslots switch specifies a quantization table number for each color +component, in the order in which the components appear in the JPEG SOF marker. +For example, to create a separate table for each of Y,Cb,Cr, you could +provide a -qtables file that defines three quantization tables and say +"-qslots 0,1,2". If -qslots gives fewer table numbers than there are color +components, then the last table number is repeated as necessary. + + +Sampling Factor Adjustment +-------------------------- + +By default, cjpeg uses 2:1 horizontal and vertical downsampling when +compressing YCbCr data, and no downsampling for all other color spaces. +You can override this default with the -sample switch: + + -sample HxV[,...] Set JPEG sampling factors for each color + component. + +The -sample switch specifies the JPEG sampling factors for each color +component, in the order in which they appear in the JPEG SOF marker. +If you specify fewer HxV pairs than there are components, the remaining +components are set to 1x1 sampling. For example, the default YCbCr setting +is equivalent to "-sample 2x2,1x1,1x1", which can be abbreviated to +"-sample 2x2". + +There are still some JPEG decoders in existence that support only 2x1 +sampling (also called 4:2:2 sampling). Compatibility with such decoders can +be achieved by specifying "-sample 2x1". This is not recommended unless +really necessary, since it increases file size and encoding/decoding time +with very little quality gain. + + +Multiple Scan / Progression Control +----------------------------------- + +By default, cjpeg emits a single-scan sequential JPEG file. The +-progressive switch generates a progressive JPEG file using a default series +of progression parameters. You can create multiple-scan sequential JPEG +files or progressive JPEG files with custom progression parameters by using +the -scans switch: + + -scans file Use the scan sequence given in the named file. + +The specified file should be a text file containing a "scan script". +The script specifies the contents and ordering of the scans to be emitted. +Each entry in the script defines one scan. A scan definition specifies +the components to be included in the scan, and for progressive JPEG it also +specifies the progression parameters Ss,Se,Ah,Al for the scan. Scan +definitions are separated by semicolons (';'). A semicolon after the last +scan definition is optional. + +Each scan definition contains one to four component indexes, optionally +followed by a colon (':') and the four progressive-JPEG parameters. The +component indexes denote which color component(s) are to be transmitted in +the scan. Components are numbered in the order in which they appear in the +JPEG SOF marker, with the first component being numbered 0. (Note that these +indexes are not the "component ID" codes assigned to the components, just +positional indexes.) + +The progression parameters for each scan are: + Ss Zigzag index of first coefficient included in scan + Se Zigzag index of last coefficient included in scan + Ah Zero for first scan of a coefficient, else Al of prior scan + Al Successive approximation low bit position for scan +If the progression parameters are omitted, the values 0,63,0,0 are used, +producing a sequential JPEG file. cjpeg automatically determines whether +the script represents a progressive or sequential file, by observing whether +Ss and Se values other than 0 and 63 appear. (The -progressive switch is +not needed to specify this; in fact, it is ignored when -scans appears.) +The scan script must meet the JPEG restrictions on progression sequences. +(cjpeg checks that the spec's requirements are obeyed.) + +Scan script files are free format, in that arbitrary whitespace can appear +between numbers and around punctuation. Also, comments can be included: a +comment starts with '#' and extends to the end of the line. For additional +legibility, commas or dashes can be placed between values. (Actually, any +single punctuation character other than ':' or ';' can be inserted.) For +example, the following two scan definitions are equivalent: + 0 1 2: 0 63 0 0; + 0,1,2 : 0-63, 0,0 ; + +Here is an example of a scan script that generates a partially interleaved +sequential JPEG file: + + 0; # Y only in first scan + 1 2; # Cb and Cr in second scan + +Here is an example of a progressive scan script using only spectral selection +(no successive approximation): + + # Interleaved DC scan for Y,Cb,Cr: + 0,1,2: 0-0, 0, 0 ; + # AC scans: + 0: 1-2, 0, 0 ; # First two Y AC coefficients + 0: 3-5, 0, 0 ; # Three more + 1: 1-63, 0, 0 ; # All AC coefficients for Cb + 2: 1-63, 0, 0 ; # All AC coefficients for Cr + 0: 6-9, 0, 0 ; # More Y coefficients + 0: 10-63, 0, 0 ; # Remaining Y coefficients + +Here is an example of a successive-approximation script.

For lower quality settings, you'd probably want to use +a script with fewer stages of successive approximation (otherwise the +initial scans will be really bad). For higher quality settings, you might +want to use more stages of successive approximation (so that the initial +scans are not too large). diff --git a/project/jni/sdl2_image/external/jpeg-9b/wrbmp.c b/project/jni/sdl2_image/external/jpeg-9b/wrbmp.c new file mode 100644 index 000000000..3283b0f15 --- /dev/null +++ b/project/jni/sdl2_image/external/jpeg-9b/wrbmp.c @@ -0,0 +1,442 @@ +/* + * wrbmp.c + * + * Copyright (C) 1994-1996, Thomas G.

A comment block is +added to the file. +.PP +The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file. +Although the standard doesn't actually define what COM blocks are for, they +are widely used to hold user-supplied text strings. This lets you add +annotations, titles, index terms, etc to your JPEG files, and later retrieve +them as text. COM blocks do not interfere with the image stored in the JPEG +file. The maximum size of a COM block is 64K, but you can have as many of +them as you like in one JPEG file. +.PP +.B wrjpgcom +adds a COM block, containing text you provide, to a JPEG file. +Ordinarily, the COM block is added after any existing COM blocks; but you +can delete the old COM blocks if you wish. +.SH OPTIONS +Switch names may be abbreviated, and are not case sensitive. +.TP +.B \-replace +Delete any existing COM blocks from the file. +.TP +.BI \-comment " text" +Supply text for new COM block on command line. +.TP +.BI \-cfile " name" +Read text for new COM block from named file. +.PP +If you have only one line of comment text to add, you can provide it on the +command line with +.BR \-comment . +The comment text must be surrounded with quotes so that it is treated as a +single argument. Longer comments can be read from a text file. +.PP +If you give neither +.B \-comment +nor +.BR \-cfile , +then +.B wrjpgcom +will read the comment text from standard input. (In this case an input image +file name MUST be supplied, so that the source JPEG file comes from somewhere +else.) You can enter multiple lines, up to 64KB worth. Type an end-of-file +indicator (usually control-D) to terminate the comment text entry. +.PP +.B wrjpgcom +will not add a COM block if the provided comment string is empty. Therefore +\fB\-replace \-comment ""\fR can be used to delete all COM blocks from a file. +.SH EXAMPLES +.LP +Add a short comment to in.jpg, producing out.jpg: +.IP +.B wrjpgcom \-c +\fI"View of my back yard" in.jpg +.B > +.I out.jpg +.PP +Attach a long comment previously stored in comment.txt: +.IP +.B wrjpgcom +.I in.jpg +.B < +.I comment.txt +.B > +.I out.jpg +.PP +or equivalently +.IP +.B wrjpgcom +.B -cfile +.I comment.txt +.B < +.I in.jpg +.B > +.I out.jpg +.SH SEE ALSO +.BR cjpeg (1), +.BR djpeg (1), +.BR jpegtran (1), +.BR rdjpgcom (1) +.SH AUTHOR +Independent JPEG Group diff --git a/project/jni/sdl2_image/external/jpeg-9b/wrjpgcom.c b/project/jni/sdl2_image/external/jpeg-9b/wrjpgcom.c new file mode 100644 index 000000000..d1bfcc9d5 --- /dev/null +++ b/project/jni/sdl2_image/external/jpeg-9b/wrjpgcom.c @@ -0,0 +1,599 @@ +/* + * wrjpgcom.c + * + * Copyright (C) 1994-1997, Thomas G.

Because of + the new png_longjmp() function they are no longer needed. + +Version 1.5.0beta11 [March 6, 2010] + Removed checking for already-included setjmp.h from pngconf.h + Fixed inconsistent indentations and made numerous cosmetic changes. + Revised the "SEE ALSO" style of libpng.3, libpngpf.3, and png.5 + +Version 1.5.0beta12 [March 9, 2010] + Moved "#include png.h" inside pngpriv.h and removed "#include png.h" from + the source files, along with "#define PNG_EXPOSE_INTERNAL_STRUCTURES" + and "#define PNG_NO_PEDANTIC_WARNINGS" (John Bowler). + Created new pngdebug.h and moved debug definitions there. + +Version 1.5.0beta13 [March 10, 2010] + Protect pngstruct.h, pnginfo.h, and pngdebug.h from being included twice. + Revise the "#ifdef" blocks in png_inflate() so it will compile when neither + PNG_USER_CHUNK_MALLOC_MAX nor PNG_SET_CHUNK_MALLOC_LIMIT_SUPPORTED + is defined. + Removed unused png_measure_compressed_chunk() from pngpriv.h and libpngpf.3 + Moved the 'config.h' support from pngconf.h to pngpriv.h + Removed PNGAPI from the png_longjmp_ptr typedef. + Eliminated dependence of pngtest.c on the private pngdebug.h file. + Make all png_debug macros into *unterminated* statements or + expressions (i.e. a trailing ';' must always be added) and correct + the format statements in various png_debug messages. + +Version 1.5.0beta14 [March 14, 2010] + Removed direct access to png_ptr->io_ptr from the Windows code in pngtest.c + Revised Makefile.am to account for recent additions and replacements. + Corrected CE and OS/2 DEF files (scripts/png*def) for symbols removed and + added ordinal numbers to the Windows DEF file and corrected the duplicated + ordinal numbers on CE symbols that are commented out. + Added back in export symbols that can be present in the Windows build but + are disabled by default. + PNG_EXPORT changed to include an 'ordinal' field for DEF file generation. + PNG_CALLBACK added to make callback definitions uniform. PNGAPI split + into PNGCAPI (base C form), PNGAPI (exports) and PNGCBAPI (callbacks), + and appropriate changes made to all files. Cygwin builds re-hinged to + allow procedure call standard changes and to remove the need for the DEF + file (fixes build on Cygwin). + Enabled 'attribute' warnings that are relevant to library APIs and callbacks. + Changed rules for generation of the various symbol files and added a new + rule for a DEF file (which is also added to the distribution). + Updated the symbol file generation to stop it adding spurious spaces + to EOL (coming from preprocessor macro expansion). Added a facility + to join tokens in the output and rewrite *.dfn to use this. + Eliminated scripts/*.def in favor of libpng.def; updated projects/visualc71 + and removed scripts/makefile.cygwin. + Made PNG_BUILD_DLL safe: it can be set whenever a DLL is being built. + Removed the include of sys/types.h - apparently unnecessary now on the + platforms on which it happened (all but Mac OS and RISC OS). + Moved the Mac OS test into pngpriv.h (the only place it is used.) + +Version 1.5.0beta15 [March 17, 2010] + Added symbols.chk target to Makefile.am to validate the symbols in png.h + against the new DEF file scripts/symbols.def. + Changed the default DEF file back to pngwin.def. + Removed makefile.mingw. + Eliminated PNG_NO_EXTERN and PNG_ALL_EXTERN + +Version 1.5.0beta16 [April 1, 2010] + Make png_text_struct independent of PNG_iTXt_SUPPORTED, so that + fields are initialized in all configurations. The READ/WRITE + macros (PNG_(READ|WRITE)_iTXt_SUPPORTED) still function as + before to disable code to actually read or write iTXt chunks + and iTXt_SUPPORTED can be used to detect presence of either + read or write support (but it is probably better to check for + the one actually required - read or write.) + Combined multiple png_warning() calls for a single error. + Restored the macro definition of png_check_sig(). + +Version 1.5.0beta17 [April 17, 2010] + Added some "(long)" typecasts to printf calls in png_handle_cHRM(). + Documented the fact that png_set_dither() was disabled since libpng-1.4.0. + Reenabled png_set_dither() but renamed it to png_set_quantize() to reflect + more accurately what it actually does. At the same time, renamed + the PNG_DITHER_[RED,GREEN_BLUE]_BITS macros to + PNG_QUANTIZE_[RED,GREEN,BLUE]_BITS. + Added some "(long)" typecasts to printf calls in png_handle_cHRM(). + Freeze build-time only configuration in the build. + In all prior versions of libpng most configuration options + controlled by compiler #defines had to be repeated by the + application code that used libpng. This patch changes this + so that compilation options that can only be changed at build + time are frozen in the build. Options that are compiler + dependent (and those that are system dependent) are evaluated + each time - pngconf.h holds these. Options that can be changed + per-file in the application are in png.h. Frozen options are + in the new installed header file pnglibconf.h (John Bowler) + Removed the xcode project because it has not been updated to work + with libpng-1.5.0. + Removed the ability to include optional pngusr.h + +Version 1.5.0beta18 [April 17, 2010] + Restored the ability to include optional pngusr.h + Moved replacements for png_error() and png_warning() from the + contrib/pngminim project to pngerror.c, for use when warnings or + errors are disabled via PNG_NO_WARN or PNG_NO_ERROR_TEXT, to avoid + storing unneeded error/warning text. + Updated contrib/pngminim project to work with the new pnglibconf.h + Added some PNG_NO_* defines to contrib/pngminim/*/pngusr.h to save space. + +Version 1.5.0beta19 [April 24, 2010] + Added PNG_{READ,WRITE}_INT_FUNCTIONS_SUPPORTED. This allows the functions + to read and write ints to be disabled independently of PNG_USE_READ_MACROS, + which allows libpng to be built with the functions even though the default + is to use the macros - this allows applications to choose at app build + time whether or not to use macros (previously impossible because the + functions weren't in the default build.) + Changed Windows calling convention back to __cdecl for API functions. + For Windows/x86 platforms only: + __stdcall is no longer needed for Visual Basic, so libpng-1.5.0 uses + __cdecl throughout (both API functions and callbacks) on Windows/x86 + platforms. + Replaced visualc6 and visualc71 projects with new vstudio project + Relaxed the overly-restrictive permissions of some files. + +Version 1.5.0beta20 [April 24, 2010] + Relaxed more overly-restrictive permissions of some files. + +Version 1.5.0beta21 [April 27, 2010] + Removed some unwanted binary bytes and changed CRLF to NEWLINE in the new + vstudio project files, and some trivial editing of some files in the + scripts directory. + Set PNG_NO_READ_BGR, PNG_NO_IO_STATE, and PNG_NO_TIME_RFC1123 in + contrib/pngminim/decoder/pngusr.h to make a smaller decoder application. + +Version 1.5.0beta22 [April 28, 2010] + Fixed dependencies of GET_INT_32 - it does not require READ_INT_FUNCTIONS + because it has a macro equivalent. + Improved the options.awk script; added an "everything off" option. + Revised contrib/pngminim to use the "everything off" option in pngusr.dfa. + +Version 1.5.0beta23 [April 29, 2010] + Corrected PNG_REMOVED macro to take five arguments. + The macro was documented with two arguments (name,ordinal), however + the symbol checking .dfn files assumed five arguments. The five + argument form seems more useful so it is changed to that. + Corrected PNG_UNKNOWN_CHUNKS_SUPPORTED to PNG_HANDLE_AS_UNKNOWN_SUPPORTED + in gregbook/readpng2.c + Corrected protection of png_get_user_transform_ptr. The API declaration in + png.h is removed if both READ and WRITE USER_TRANSFORM are turned off + but was left defined in pngtrans.c + Added logunsupported=1 to cause pnglibconf.h to document disabled options. + This makes the installed pnglibconf.h more readable but causes no + other change. The intention is that users of libpng will find it + easier to understand if an API they need is missing. + Include png_reset_zstream() in png.c only when PNG_READ_SUPPORTED is defined. + Removed dummy_inflate.c from contrib/pngminim/encoder + Removed contrib/pngminim/*/gather.sh; gathering is now done in the makefile. + +Version 1.5.0beta24 [May 7, 2010] + Use bitwise "&" instead of arithmetic mod in pngrutil.c calculation of the + offset of the png_ptr->rowbuf pointer into png_ptr->big_row_buf. + Added more blank lines for readability. + +Version 1.5.0beta25 [June 18, 2010] + In pngpread.c: png_push_have_row() add check for new_row > height + Removed the now-redundant check for out-of-bounds new_row from example.c + +Version 1.5.0beta26 [June 18, 2010] + In pngpread.c: png_push_process_row() add check for too many rows. + +Version 1.5.0beta27 [June 18, 2010] + Removed the check added in beta25 as it is now redundant. + +Version 1.5.0beta28 [June 20, 2010] + Rewrote png_process_IDAT_data to consistently treat extra data as warnings + and handle end conditions more cleanly. + Removed the new (beta26) check in png_push_process_row(). + +Version 1.5.0beta29 [June 21, 2010] + Revised scripts/options.awk to work on Sunos (but still doesn't work) + Added comment to options.awk and contrib/pngminim/*/makefile to try nawk. + +Version 1.5.0beta30 [June 22, 2010] + Stop memory leak when reading a malformed sCAL chunk. + +Version 1.5.0beta31 [June 26, 2010] + Revised pngpread.c patch of beta28 to avoid an endless loop. + Removed some trailing blanks. + +Version 1.5.0beta32 [June 26, 2010] + Removed leftover scripts/options.patch and scripts/options.rej + +Version 1.5.0beta33 [July 6, 3010] + Made FIXED and FLOATING options consistent in the APIs they enable and + disable. Corrected scripts/options.awk to handle both command line + options and options specified in the .dfa files. + Changed char *msg to PNG_CONST char *msg in pngrutil.c + Make png_set_sRGB_gAMA_and_cHRM set values using either the fixed or + floating point APIs, but not both. + Reversed patch to remove error handler when the jmp_buf is stored in the + main program structure, not the png_struct. + The error handler is needed because the default handler in libpng will + always use the jmp_buf in the library control structure; this is never + set. The gregbook code is a useful example because, even though it + uses setjmp/longjmp, it shows how error handling can be implemented + using control mechanisms not directly supported by libpng. The + technique will work correctly with mechanisms such as Microsoft + Structure Exceptions or C++ exceptions (compiler willing - note that gcc + does not by default support interworking of C and C++ error handling.) + Reverted changes to call png_longjmp in contrib/gregbook where it is not + appropriate. If mainprog->jmpbuf is used by setjmp, then png_longjmp + cannot be used. + Changed "extern PNG_EXPORT" to "PNG_EXPORT" in png.h (Jan Nijtmans) + Changed "extern" to "PNG_EXTERN" in pngpriv.h (except for the 'extern "C" {') + +Version 1.5.0beta34 [July 12, 2010] + Put #ifndef PNG_EXTERN, #endif around the define PNG_EXTERN in pngpriv.h + +Version 1.5.0beta35 [July 24, 2010] + Removed some newly-added TAB characters. + Added -DNO_PNG_SNPRINTF to CFLAGS in scripts/makefile.dj2 + Moved the definition of png_snprintf() outside of the enclosing + #ifdef blocks in pngconf.h + +Version 1.5.0beta36 [July 29, 2010] + Patches by John Bowler: + Fixed point APIs are now supported throughout (no missing APIs). + Internal fixed point arithmetic support exists for all internal floating + point operations. + sCAL validates the floating point strings it is passed. + Safe, albeit rudimentary, Watcom support is provided by PNG_API_RULE==2 + Two new APIs exist to get the number of passes without turning on the + PNG_INTERLACE transform and to get the number of rows in the current + pass. + A new test program, pngvalid.c, validates the gamma code. + Errors in the 16-bit gamma correction (overflows) have been corrected. + cHRM chunk testing is done consistently (previously the floating point + API bypassed it, because the test really didn't work on FP, now the test + is performed on the actual values to be stored in the PNG file so it + works in the FP case too.) + Most floating point APIs now simply call the fixed point APIs after + converting the values to the fixed point form used in the PNG file. + The standard headers no longer include zlib.h, which is currently only + required for pngstruct.h and can therefore be internal. + Revised png_get_int_32 to undo the PNG two's complement representation of + negative numbers. + +Version 1.5.0beta37 [July 30, 2010] + Added a typecast in png_get_int_32() in png.h and pngrutil.h to avoid + a compiler warning. + Replaced oFFs 0,0 with oFFs -10,20 in pngtest.png + +Version 1.5.0beta38 [July 31, 2010] + Implemented remaining "_fixed" functions. + Corrected a number of recently introduced warnings mostly resulting from + safe but uncast assignments to shorter integers. Also added a zlib + VStudio release library project because the latest zlib Official Windows + build does not include such a thing. + Revised png_get_int_16() to be similar to png_get_int_32(). + Restored projects/visualc71. + +Version 1.5.0beta39 [August 2, 2010] + VisualC/GCC warning fixes, VisualC build fixes + The changes include support for function attributes in VC in addition to + those already present in GCC - necessary because without these some + warnings are unavoidable. Fixes include signed/unsigned fixes in + pngvalid and checks with gcc -Wall -Wextra -Wunused. + VC requires function attributes on function definitions as well as + declarations, PNG_FUNCTION has been added to enable this and the + relevant function definitions changed. + +Version 1.5.0beta40 [August 6, 2010] + Correct use of _WINDOWS_ in pngconf.h + Removed png_mem_ #defines; they are no longer used. + Added the sRGB chunk to pngtest.png + +Version 1.5.0beta41 [August 11, 2010] + Added the cHRM chunk to pngtest.png + Don't try to use version-script with cygwin/mingw. + Revised contrib/gregbook to work under cygwin/mingw. + +Version 1.5.0beta42 [August 18, 2010] + Add .dll.a to the list of extensions to be symlinked by Makefile.am (Yaakov) + Made all API functions that have const arguments and constant string + literal pointers declare them (John Bowler). + +Version 1.5.0beta43 [August 20, 2010] + Removed spurious tabs, shorten long lines (no source change) + Also added scripts/chkfmt to validate the format of all the files that can + reasonably be validated (it is suggested to run "make distclean" before + checking, because some machine generated files have long lines.) + Reformatted the CHANGES file to be more consistent throughout. + Made changes to address various issues identified by GCC, mostly + signed/unsigned and shortening problems on assignment but also a few + difficult to optimize (for GCC) loops. + Fixed non-GCC fixed point builds. In png.c a declaration was misplaced + in an earlier update. Fixed to declare the auto variables at the head. + Use cexcept.h in pngvalid.c. + +Version 1.5.0beta44 [August 24, 2010] + Updated CMakeLists.txt to use CMAKE_INSTALL_LIBDIR variable; useful for + installing libpng in /usr/lib64 (Funda Wang). + Revised CMakeLists.txt to put the man pages in share/man/man* not man/man* + Revised CMakeLists.txt to make symlinks instead of copies when installing. + Changed PNG_LIB_NAME from pngNN to libpngNN in CMakeLists.txt (Philip Lowman) + Implemented memory checks within pngvalid + Reformatted/rearranged pngvalid.c to assist use of progressive reader. + Check interlaced images in pngvalid + Clarified pngusr.h comments in pnglibconf.dfa + Simplified the pngvalid error-handling code now that cexcept.h is in place. + Implemented progressive reader in pngvalid.c for standard tests + Implemented progressive read in pngvalid.c gamma tests + Turn on progressive reader in pngvalid.c by default and tidy code. + +Version 1.5.0beta45 [August 26, 2010] + Added an explicit make step to projects/vstudio for pnglibconf.h + Also corrected zlib.vcxproj into which Visual Studio had introduced + what it calls an "authoring error". The change to make pnglibconf.h + simply copies the file; in the future it may actually generate the + file from scripts/pnglibconf.dfa as the other build systems do. + Changed pngvalid to work when floating point APIs are disabled + Renamed the prebuilt scripts/pnglibconf.h to scripts/pnglibconf.h.prebuilt + Supply default values for PNG_USER_PRIVATEBUILD and PNG_USER_DLLFNAME_POSTFIX + in pngpriv.h in case the user neglected to define them in their pngusr.h + +Version 1.5.0beta46 [August 28, 2010] + Added new private header files to libpng_sources in CMakeLists.txt + Added PNG_READ_16BIT, PNG_WRITE_16BIT, and PNG_16BIT options. + Added reference to scripts/pnglibconf.h.prebuilt in the visualc71 project. + +Version 1.5.0beta47 [September 11, 2010] + Fixed a number of problems with 64-bit compilation reported by Visual + Studio 2010 (John Bowler). + +Version 1.5.0beta48 [October 4, 2010] + Updated CMakeLists.txt (Philip Lowman). + Revised autogen.sh to recognize and use $AUTOCONF, $AUTOMAKE, $AUTOHEADER, + $AUTOPOINT, $ACLOCAL and $LIBTOOLIZE + Fixed problem with symbols creation in Makefile.am which was assuming that + all versions of ccp write to standard output by default (Martin Banky). The + bug was introduced in libpng-1.2.9beta5. + Removed unused mkinstalldirs. + +Version 1.5.0beta49 [October 8, 2010] + Undid Makefile.am revision of 1.5.0beta48. + +Version 1.5.0beta50 [October 14, 2010] + Revised Makefile.in to account for mkinstalldirs being removed. + Added some "(unsigned long)" typecasts in printf statements in pngvalid.c. + Suppressed a compiler warning in png_handle_sPLT(). + Check for out-of-range text compression mode in png_set_text(). + +Version 1.5.0beta51 [October 15, 2010] + Changed embedded dates to "(PENDING RELEASE) in beta releases (and future + rc releases) to minimize the difference between releases. + +Version 1.5.0beta52 [October 16, 2010] + Restored some of the embedded dates (in png.h, png.c, documentation, etc.) + +Version 1.5.0beta53 [October 18, 2010] + Updated INSTALL to mention using "make maintainer-clean" and to remove + obsolete statement about a custom ltmain.sh + Disabled "color-tests" by default in Makefile.am so it will work with + automake versions earlier than 1.11.1 + Use document name "libpng-manual.txt" instead of "libpng-.txt" + to simplify version differences. + Removed obsolete remarks about setjmp handling from INSTALL. + Revised and renamed the typedef in png.h and png.c that was designed + to catch library and header mismatch. + +Version 1.5.0beta54 [November 10, 2010] + Require 48 bytes, not 64 bytes, for big_row_buf in overflow checks. + Used a consistent structure for the pngget.c functions. + +Version 1.5.0beta55 [November 21, 2010] + Revised png_get_uint_32, png_get_int_32, png_get_uint_16 (Cosmin) + Moved reading of file signature into png_read_sig (Cosmin) + Fixed atomicity of chunk header serialization (Cosmin) + Added test for io_state in pngtest.c (Cosmin) + Added "#!/bin/sh" at the top of contrib/pngminim/*/gather.sh scripts. + Changes to remove gcc warnings (John Bowler) + Certain optional gcc warning flags resulted in warnings in libpng code. + With these changes only -Wconversion and -Wcast-qual cannot be turned on. + Changes are trivial rearrangements of code. -Wconversion is not possible + for pngrutil.c (because of the widespread use of += et al on variables + smaller than (int) or (unsigned int)) and -Wcast-qual is not possible + with pngwio.c and pngwutil.c because the 'write' callback and zlib + compression both fail to declare their input buffers with 'const'. + +Version 1.5.0beta56 [December 7, 2010] + Added the private PNG_UNUSED() macro definition in pngpriv.h. + Added some commentary about PNG_EXPORT in png.h and pngconf.h + Revised PNG_EXPORT() macro and added PNG_EXPORTA() macro, with the + objective of simplifying and improving the cosmetic appearance of png.h. + Fixed some incorrect "=" macro names in pnglibconf.dfa + Included documentation of changes in 1.5.0 from 1.4.x in libpng-manual.txt + +Version 1.5.0beta57 [December 9, 2010] + Documented the pngvalid gamma error summary with additional comments and + print statements. + Improved missing symbol handling in checksym.awk; symbols missing in both + the old and new files can now be optionally ignored, treated as errors + or warnings. + Removed references to pngvcrd.c and pnggccrd.c from the vstudio project. + Updated "libpng14" to "libpng15" in the visualc71 project. + Enabled the strip16 tests in pngvalid.` + Don't display test results (except PASS/FAIL) when running "make test". + Instead put them in pngtest-log.txt + Added "--with-zprefix=" to configure.ac + Updated the prebuilt configuration files to autoconf version 2.68 + +Version 1.5.0beta58 [December 19, 2010] + Fixed interlace image handling and add test cases (John Bowler) + Fixed the clean rule in Makefile.am to remove pngtest-log.txt + Made minor changes to work around warnings in gcc 3.4 + +Version 1.5.0rc01 [December 27, 2010] + No changes. + +Version 1.5.0rc02 [December 27, 2010] + Eliminated references to the scripts/*.def files in project/visualc71. + +Version 1.5.0rc03 [December 28, 2010] + Eliminated scripts/*.def and revised Makefile.am accordingly + +Version 1.5.0rc04 [December 29, 2010] + Fixed bug in background transformation handling in pngrtran.c (it was + looking for the flag in png_ptr->transformations instead of in + png_ptr->flags) (David Raymond). + +Version 1.5.0rc05 [December 31, 2010] + Fixed typo in a comment in CMakeLists.txt (libpng14 => libpng15) (Cosmin) + +Version 1.5.0rc06 [January 4, 2011] + Changed the new configure option "zprefix=string" to "zlib-prefix=string" + +Version 1.5.0rc07 [January 4, 2011] + Updated copyright year. + +Version 1.5.0 [January 6, 2011] + No changes. + +version 1.5.1beta01 [January 8, 2011] + Added description of png_set_crc_action() to the manual. + Added a note in the manual that the type of the iCCP profile was changed + from png_charpp to png_bytepp in png_get_iCCP(). This change happened + in version 1.5.0beta36 but is not noted in the CHANGES. Similarly, + it was changed from png_charpp to png_const_bytepp in png_set_iCCP(). + Ensure that png_rgb_to_gray ignores palette mapped images, if libpng + internally happens to call it with one, and fixed a failure to handle + palette mapped images correctly. This fixes CVE-2690. + +Version 1.5.1beta02 [January 14, 2011] + Fixed a bug in handling of interlaced images (bero at arklinux.org). + Updated CMakeLists.txt (Clifford Yapp) + +Version 1.5.1beta03 [January 14, 2011] + Fixed typecasting of some png_debug() statements (Cosmin) + +Version 1.5.1beta04 [January 16, 2011] + Updated documentation of png_set|get_tRNS() (Thomas Klausner). + Mentioned in the documentation that applications must #include "zlib.h" + if they need access to anything in zlib.h, and that a number of + macros such as png_memset() are no longer accessible by applications. + Corrected pngvalid gamma test "sample" function to access all of the color + samples of each pixel, instead of sampling the red channel three times. + Prefixed variable names index, div, exp, gamma with "png_" to avoid "shadow" + warnings, and (mistakenly) changed png_exp() to exp(). + +Version 1.5.1beta05 [January 16, 2011] + Changed variable names png_index, png_div, png_exp, and png_gamma to + char_index, divisor, exp_b10, and gamma_val, respectively, and + changed exp() back to png_exp(). + +Version 1.5.1beta06 [January 20, 2011] + Prevent png_push_crc_skip() from hanging while reading an unknown chunk + or an over-large compressed zTXt chunk with the progressive reader. + Eliminated more GCC "shadow" warnings. + Revised png_fixed() in png.c to avoid compiler warning about reaching the + end without returning anything. + +Version 1.5.1beta07 [January 22, 2011] + In the manual, describe the png_get_IHDR() arguments in the correct order. + Added const_png_structp and const_png_infop types, and used them in + prototypes for most png_get_*() functions. + +Version 1.5.1beta08 [January 23, 2011] + Added png_get_io_chunk_type() and deprecated png_get_io_chunk_name() + Added synopses for the IO_STATE functions and other missing synopses + to the manual. Removed the synopses from libpngpf.3 because they + were out of date and no longer useful. Better information can be + obtained by reading the prototypes and comments in pngpriv.h + Attempted to fix cpp on Solaris with S. Studio 12 cc, fix build + Added a make macro DFNCPP that is a CPP that will accept the tokens in + a .dfn file and adds configure stuff to test for such a CPP. ./configure + should fail if one is not available. + Corrected const_png_ in png.h to png_const_ to avoid polluting the namespace. + Added png_get_current_row_number and png_get_current_pass_number for the + benefit of the user transform callback. + Added png_process_data_pause and png_process_data_skip for the benefit of + progressive readers that need to stop data processing or want to optimize + skipping of unread data (e.g., if the reader marks a chunk to be skipped.) + +Version 1.5.1beta09 [January 24, 2011] + Enhanced pngvalid, corrected an error in gray_to_rgb, corrected doc error. + pngvalid contains tests of transforms, which tests are currently disabled + because they are incompletely tested. gray_to_rgb was failing to expand + the bit depth for smaller bit depth images; this seems to be a long + standing error and resulted, apparently, in invalid output + (CVE-2011-0408, CERT VU#643140). The documentation did not accurately + describe what libpng really does when converting RGB to gray. + +Version 1.5.1beta10 [January 27, 2010] + Fixed incorrect examples of callback prototypes in the manual, that were + introduced in libpng-1.0.0. + In addition the order of the png_get_uint macros with respect to the + relevant function definitions has been reversed. This helps the + preprocessing of the symbol files be more robust. Furthermore, the + symbol file preprocessing now uses -DPNG_NO_USE_READ_MACROS even when + the library may actually be built with PNG_USE_READ_MACROS; this stops + the read macros interfering with the symbol file format. + Made the manual, synopses, and function prototypes use the function + argument names file_gamma, int_file_gamma, and srgb_intent consistently. + +Version 1.5.1beta11 [January 28, 2011] + Changed PNG_UNUSED from "param=param;" to "{if(param){}}". + Corrected local variable type in new API png_process_data_skip() + The type was self-evidently incorrect but only causes problems on 64-bit + architectures. + Added transform tests to pngvalid and simplified the arguments. + +Version 1.5.1rc01 [January 29, 2011] + No changes. + +Version 1.5.1rc02 [January 31, 2011] + Added a request in the manual that applications do not use "png_" or + "PNG_" to begin any of their own symbols. + Changed PNG_UNUSED to "(void)param;" and updated the commentary in pngpriv.h + +Version 1.5.1 [February 3, 2011] + No changes. + +Version 1.5.2beta01 [February 13, 2011] + More -Wshadow fixes for older gcc compilers. Older gcc versions apparently + check formal parameters names in function declarations (as well as + definitions) to see if they match a name in the global namespace. + Revised PNG_EXPORTA macro to not use an empty parameter, to accommodate the + old VisualC++ preprocessor. + Turned on interlace handling in png_read_png(). + Fixed gcc pedantic warnings. + Handle longjmp in Cygwin. + Fixed png_get_current_row_number() in the interlaced case. + Cleaned up ALPHA flags and transformations. + Implemented expansion to 16 bits. + +Version 1.5.2beta02 [February 19, 2011] + Fixed mistake in the descriptions of user read_transform and write_transform + function prototypes in the manual. The row_info struct is png_row_infop. + Reverted png_get_current_row_number() to previous (1.5.2beta01) behavior. + Corrected png_get_current_row_number documentation + Fixed the read/write row callback documentation. + This documents the current behavior, where the callback is called after + every row with information pertaining to the next row. + +Version 1.5.2beta03 [March 3, 2011] + Fixed scripts/makefile.vcwin32 + Updated contrib/pngsuite/README to add the word "modify". + Define PNG_ALLOCATED to blank when _MSC_VER<1300. + +Version 1.5.2rc01 [March 19, 2011] + Define remaining attributes to blank when MSC_VER<1300. + ifdef out mask arrays in pngread.c when interlacing is not supported. + +Version 1.5.2rc02 [March 22, 2011] + Added a hint to try CPP=/bin/cpp if "cpp -E" fails in scripts/pnglibconf.mak + and in contrib/pngminim/*/makefile, eg., on SunOS 5.10, and removed "strip" + from the makefiles. + Fixed a bug (present since libpng-1.0.7) that makes png_handle_sPLT() fail + to compile when PNG_NO_POINTER_INDEXING is defined (Chubanov Kirill) + +Version 1.5.2rc03 [March 24, 2011] + Don't include standard header files in png.h while building the symbol table, + to avoid cpp failure on SunOS (introduced PNG_BUILDING_SYMBOL_TABLE macro). + +Version 1.5.2 [March 31, 2011] + No changes. + +Version 1.5.3beta01 [April 1, 2011] + Re-initialize the zlib compressor before compressing non-IDAT chunks. + Added API functions (png_set_text_compression_level() and four others) to + set parameters for zlib compression of non-IDAT chunks. + +Version 1.5.3beta02 [April 3, 2011] + Updated scripts/symbols.def with new API functions. + Only compile the new zlib re-initializing code when text or iCCP is + supported, using PNG_WRITE_COMPRESSED_TEXT_SUPPORTED macro. + Improved the optimization of the zlib CMF byte (see libpng-1.2.6beta03). + Optimize the zlib CMF byte in non-IDAT compressed chunks + +Version 1.5.3beta03 [April 16, 2011] + Fixed gcc -ansi -pedantic compile. A strict ANSI system does not have + snprintf, and the "__STRICT_ANSI__" detects that condition more reliably + than __STDC__ (John Bowler). + Removed the PNG_PTR_NORETURN attribute because it too dangerous. It tells + the compiler that a user supplied callback (the error handler) does not + return, yet there is no guarantee in practice that the application code + will correctly implement the error handler because the compiler only + issues a warning if there is a mistake (John Bowler). + Removed the no-longer-used PNG_DEPSTRUCT macro. + Updated the zlib version to 1.2.5 in the VStudio project. + Fixed 64-bit builds where png_uint_32 is smaller than png_size_t in + pngwutil.c (John Bowler). + Fixed bug with stripping the filler or alpha channel when writing, that + was introduced in libpng-1.5.2beta01 (bug report by Andrew Church). + +Version 1.5.3beta04 [April 27, 2011] + Updated pngtest.png with the new zlib CMF optimization. + Cleaned up conditional compilation code and of background/gamma handling + Internal changes only except a new option to avoid compiling the + png_build_grayscale_palette API (which is not used at all internally.) + The main change is to move the transform tests (READ_TRANSFORMS, + WRITE_TRANSFORMS) up one level to the caller of the APIs. This avoids + calls to spurious functions if all transforms are disabled and slightly + simplifies those functions. Pngvalid modified to handle this. + A minor change is to stop the strip_16 and expand_16 interfaces from + disabling each other; this allows the future alpha premultiplication + code to use 16-bit intermediate values while still producing 8-bit output. + png_do_background and png_do_gamma have been simplified to take a single + pointer to the png_struct rather than pointers to every item required + from the png_struct. This makes no practical difference to the internal + code. + A serious bug in the pngvalid internal routine 'standard_display_init' has + been fixed - this failed to initialize the red channel and accidentally + initialized the alpha channel twice. + Changed png_struct jmp_buf member name from png_jmpbuf to tmp_jmpbuf to + avoid a possible clash with the png_jmpbuf macro on some platforms. + +Version 1.5.3beta05 [May 6, 2011] + Added the "_POSIX_SOURCE" feature test macro to ensure libpng sees the + correct API. _POSIX_SOURCE is defined in pngpriv.h, pngtest.c and + pngvalid.c to ensure that POSIX conformant systems disable non-POSIX APIs. + Removed png_snprintf and added formatted warning messages. This change adds + internal APIs to allow png_warning messages to have parameters without + requiring the host OS to implement snprintf. As a side effect the + dependency of the tIME-supporting RFC1132 code on stdio is removed and + PNG_NO_WARNINGS does actually work now. + Pass "" instead of '\0' to png_default_error() in png_err(). This mistake + was introduced in libpng-1.2.20beta01. This fixes CVE-2011-2691. + Added PNG_WRITE_OPTIMIZE_CMF_SUPPORTED macro to make the zlib "CMF" byte + optimization configurable. + IDAT compression failed if preceded by a compressed text chunk (bug + introduced in libpng-1.5.3beta01-02). This was because the attempt to + reset the zlib stream in png_write_IDAT happened after the first IDAT + chunk had been deflated - much too late. In this change internal + functions were added to claim/release the z_stream and, hopefully, make + the code more robust. Also deflateEnd checking is added - previously + libpng would ignore an error at the end of the stream. + +Version 1.5.3beta06 [May 8, 2011] + Removed the -D_ALL_SOURCE from definitions for AIX in CMakeLists.txt + Implemented premultiplied alpha support: png_set_alpha_mode API + +Version 1.5.3beta07 [May 11, 2011] + Added expand_16 support to the high level interface. + Added named value and 'flag' gamma support to png_set_gamma. Made a minor + change from the previous (unreleased) ABI/API to hide the exact value used + for Macs - it's not a good idea to embed this in the ABI! + Moved macro definitions for PNG_HAVE_IHDR, PNG_HAVE_PLTE, and PNG_AFTER_IDAT + from pngpriv.h to png.h because they must be visible to applications + that call png_set_unknown_chunks(). + Check for up->location !PNG_AFTER_IDAT when writing unknown chunks + before IDAT. + +Version 1.5.3beta08 [May 16, 2011] + Improved "pngvalid --speed" to exclude more of pngvalid from the time. + Documented png_set_alpha_mode(), other changes in libpng.3/libpng-manual.txt + The cHRM chunk now sets the defaults for png_set_rgb_to_gray() (when negative + parameters are supplied by the caller), while in the absence of cHRM + sRGB/Rec 709 values are still used. This introduced a divide-by-zero + bug in png_handle_cHRM(). + The bKGD chunk no longer overwrites the background value set by + png_set_background(), allowing the latter to be used before the file + header is read. It never performed any useful function to override + the default anyway. + Added memory overwrite and palette image checks to pngvalid.c + Previously palette image code was poorly checked. Since the transformation + code has a special palette path in most cases this was a severe weakness. + Minor cleanup and some extra checking in pngrutil.c and pngrtran.c. When + expanding an indexed image, always expand to RGBA if transparency is + present. + +Version 1.5.3beta09 [May 17, 2011] + Reversed earlier 1.5.3 change of transformation order; move png_expand_16 + back where it was. The change doesn't work because it requires 16-bit + gamma tables when the code only generates 8-bit ones. This fails + silently; the libpng code just doesn't do any gamma correction. Moving + the tests back leaves the old, inaccurate, 8-bit gamma calculations, but + these are clearly better than none! + +Version 1.5.3beta10 [May 20, 2011] + + png_set_background() and png_expand_16() did not work together correctly. + This problem is present in 1.5.2; if png_set_background is called with + need_expand false and the matching 16 bit color libpng erroneously just + treats it as an 8-bit color because of where png_do_expand_16 is in the + transform list. This simple fix reduces the supplied colour to 8-bits, + so it gets smashed, but this is better than the current behavior. + Added tests for expand16, more fixes for palette image tests to pngvalid. + Corrects the code for palette image tests and disables attempts to + validate palette colors. + +Version 1.5.3rc01 [June 3, 2011] + No changes. + +Version 1.5.3rc02 [June 8, 2011] + Fixed uninitialized memory read in png_format_buffer() (Bug report by + Frank Busse, CVE-2011-2501, related to CVE-2004-0421). + +Version 1.5.3beta11 [June 11, 2011] + Fixed png_handle_sCAL which is broken in 1.5. This fixes CVE 2011-2692. + Added sCAL to pngtest.png + Revised documentation about png_set_user_limits() to say that it also affects + png writing. + Revised handling of png_set_user_limits() so that it can increase the + limit beyond the PNG_USER_WIDTH|HEIGHT_MAX; previously it could only + reduce it. + Make the 16-to-8 scaling accurate. Dividing by 256 with no rounding is + wrong (high by one) 25% of the time. Dividing by 257 with rounding is + wrong in 128 out of 65536 cases. Getting the right answer all the time + without division is easy. + Added "_SUPPORTED" to the PNG_WRITE_CUSTOMIZE_ZTXT_COMPRESSION macro. + Added projects/owatcom, an IDE project for OpenWatcom to replace + scripts/makefile.watcom. This project works with OpenWatcom 1.9. The + IDE autogenerates appropriate makefiles (libpng.mk) for batch processing. + The project is configurable, unlike the Visual Studio project, so long + as the developer has an awk. + Changed png_set_gAMA to limit the gamma value range so that the inverse + of the stored value cannot overflow the fixed point representation, + and changed other things OpenWatcom warns about. + Revised pngvalid.c to test PNG_ALPHA_MODE_SUPPORTED correctly. This allows + pngvalid to build when ALPHA_MODE is not supported, which is required if + it is to build on libpng 1.4. + Removed string/memory macros that are no longer used and are not + necessarily fully supportable, particularly png_strncpy and png_snprintf. + Added log option to pngvalid.c and attempted to improve gamma messages. + +Version 1.5.3 [omitted] + People found the presence of a beta release following an rc release + to be confusing; therefore we bump the version to libpng-1.5.4beta01 + and there will be no libpng-1.5.3 release. + +Version 1.5.4beta01 [June 14, 2011] + Made it possible to undefine PNG_READ_16_TO_8_ACCURATE_SCALE_SUPPORTED + to get the same (inaccurate) output as libpng-1.5.2 and earlier. + Moved definitions of PNG_HAVE_IHDR, PNG_AFTER_IDAT, and PNG_HAVE_PLTE + outside of an unknown-chunk block in png.h because they are also + needed for other uses. + +Version 1.5.4beta02 [June 14, 2011] + Fixed and clarified LEGACY 16-to-8 scaling code. + Added png_set_chop_16() API, to match inaccurate results from previous + libpng versions. + Removed the ACCURATE and LEGACY options (they are no longer useable) + Use the old scaling method for background if png_set_chop_16() was + called. + Made png_set_chop_16() API removeable by disabling PNG_CHOP_16_TO_8_SUPPORTED + +Version 1.5.4beta03 [June 15, 2011] + Fixed a problem in png_do_expand_palette() exposed by optimization in + 1.5.3beta06 + Also removed a spurious and confusing "trans" member ("trans") from png_info. + The palette expand optimization prevented expansion to an intermediate RGBA + form if tRNS was present but alpha was marked to be stripped; this exposed + a check for tRNS in png_do_expand_palette() which is inconsistent with the + code elsewhere in libpng. + Correction to the expand_16 code; removed extra instance of + png_set_scale_16_to_8 from pngpriv.h + +Version 1.5.4beta04 [June 16, 2011] + Added a missing "#ifdef PNG_READ_BACKGROUND_SUPPORTED/#endif" in pngrtran.c + Added PNG_TRANSFORM_CHOP_16 to the high-level read transforms. + Made PNG_READ_16_TO_8_ACCURATE_SCALE configurable again. If this is + not enabled, png_set_strip_16() and png_do_scale_16_to_8() aren't built. + Revised contrib/visupng, gregbook, and pngminim to demonstrate chop_16_to_8 + +Version 1.5.4beta05 [June 16, 2011] + Renamed png_set_strip_16() to png_set_scale_16() and renamed + png_set_chop_16() to png_set_strip(16) in an attempt to minimize the + behavior changes between libpng14 and libpng15. + +Version 1.5.4beta06 [June 18, 2011] + Fixed new bug that was causing both strip_16 and scale_16 to be applied. + +Version 1.5.4beta07 [June 19, 2011] + Fixed pngvalid, simplified macros, added checking for 0 in sCAL. + The ACCURATE scale macro is no longer defined in 1.5 - call the + png_scale_16_to_8 API. Made sure that PNG_READ_16_TO_8 is still defined + if the png_strip_16_to_8 API is present. png_check_fp_number now + maintains some state so that positive, negative and zero values are + identified. sCAL uses these to be strictly spec conformant. + +Version 1.5.4beta08 [June 23, 2011] + Fixed pngvalid if ACCURATE_SCALE is defined. + Updated scripts/pnglibconf.h.prebuilt. + +Version 1.5.4rc01 [June 30, 2011] + Define PNG_ALLOCATED to "restrict" only if MSC_VER >= 1400. + +Version 1.5.4 [July 7, 2011] + No changes. + +Version 1.5.5beta01 [July 13, 2011] + Fixed some typos and made other minor changes in the manual. + Updated contrib/pngminus/makefile.std (Samuli Souminen) + +Version 1.5.5beta02 [July 14, 2011] + Revised Makefile.am and Makefile.in to look in the right directory for + pnglibconf.h.prebuilt + +Version 1.5.5beta03 [July 27, 2011] + Enabled compilation with g++ compiler. This compiler does not recognize + the file extension, so it always compiles with C++ rules. Made minor + changes to pngrutil.c to cast results where C++ expects it but C does not. + Minor editing of libpng.3 and libpng-manual.txt. + +Version 1.5.5beta04 [July 29, 2011] + Revised CMakeLists.txt (Clifford Yapp) + Updated commentary about the png_rgb_to_gray() default coefficients + in the manual and in pngrtran.c + +Version 1.5.5beta05 [August 17, 2011] + Prevent unexpected API exports from non-libpng DLLs on Windows. The "_DLL" + is removed from the test of whether a DLL is being built (this erroneously + caused the libpng APIs to be marked as DLL exports in static builds under + Microsoft Visual Studio). Almost all of the libpng building configuration + is moved from pngconf.h to pngpriv.h, but PNG_DLL_EXPORT remains in + pngconf.h, though, so that it is colocated with the import definition (it + is no longer used anywhere in the installed headers). The VStudio project + definitions have been cleaned up: "_USRDLL" has been removed from the + static library builds (this was incorrect), and PNG_USE_DLL has been added + to pngvalid to test the functionality (pngtest does not supply it, + deliberately). The spurious "_EXPORTS" has been removed from the + libpng build (all these errors were a result of copy/paste between project + configurations.) + Added new types and internal functions for CIE RGB end point handling to + pngpriv.h (functions yet to be implemented). + +Version 1.5.5beta06 [August 26, 2011] + Ensure the CMAKE_LIBRARY_OUTPUT_DIRECTORY is set in CMakeLists.txt + (Clifford Yap) + Fixes to rgb_to_gray and cHRM XYZ APIs (John Bowler): + The rgb_to_gray code had errors when combined with gamma correction. + Some pixels were treated as true grey when they weren't and such pixels + and true grey ones were not gamma corrected (the original value of the + red component was used instead). APIs to get and set cHRM using color + space end points have been added and the rgb_to_gray code that defaults + based on cHRM, and the divide-by-zero bug in png_handle_cHRM (CERT + VU#477046, CVE-2011-3328, introduced in 1.5.4) have been corrected. + A considerable number of tests has been added to pngvalid for the + rgb_to_gray transform. + Arithmetic errors in rgb_to_gray whereby the calculated gray value was + truncated to the bit depth rather than rounded have been fixed except in + the 8-bit non-gamma-corrected case (where consistency seems more important + than correctness.) The code still has considerable inaccuracies in the + 8-bit case because 8-bit linear arithmetic is used. + +Version 1.5.5beta07 [September 7, 2011] + Added "$(ARCH)" option to makefile.darwin + Added SunOS support to configure.ac and Makefile.am + Changed png_chunk_benign_error() to png_warning() in png.c, in + png_XYZ_from_xy_checked(). + +Version 1.5.5beta08 [September 10, 2011] + Fixed 64-bit compilation errors (gcc). The errors fixed relate + to conditions where types that are 32 bits in the GCC 32-bit + world (uLong and png_size_t) become 64 bits in the 64-bit + world. This produces potential truncation errors which the + compiler correctly flags. + Relocated new HAVE_SOLARIS_LD definition in configure.ac + Constant changes for 64-bit compatibility (removal of L suffixes). The + 16-bit cases still use "L" as we don't have a 16-bit test system. + +Version 1.5.5rc01 [September 15, 2011] + Removed "L" suffixes in pngpriv.h + +Version 1.5.5 [September 22, 2011] + No changes. + +Version 1.5.6beta01 [September 22, 2011] + Fixed some 64-bit type conversion warnings in pngrtran.c + Moved row_info from png_struct to a local variable. + The various interlace mask arrays have been made into arrays of + bytes and made PNG_CONST and static (previously some arrays were + marked PNG_CONST and some weren't). + Additional checks have been added to the transform code to validate the + pixel depths after the transforms on both read and write. + Removed some redundant code from pngwrite.c, in png_destroy_write_struct(). + Changed chunk reading/writing code to use png_uint_32 instead of png_byte[4]. + This removes the need to allocate temporary strings for chunk names on + the stack in the read/write code. Unknown chunk handling still uses the + string form because this is exposed in the API. + +Version 1.5.6beta02 [September 26, 2011] + Added a note in the manual the png_read_update_info() must be called only + once with a particular info_ptr. + Fixed a typo in the definition of the new PNG_STRING_FROM_CHUNK(s,c) macro. + +Version 1.5.6beta03 [September 28, 2011] + Revised test-pngtest.sh to report FAIL when pngtest fails. + Added "--strict" option to pngtest, to report FAIL when the failure is + only because the resulting valid files are different. + Revised CMakeLists.txt to work with mingw and removed some material from + CMakeLists.txt that is no longer useful in libpng-1.5. + +Version 1.5.6beta04 [October 5, 2011] + Fixed typo in Makefile.in and Makefile.am ("-M Wl" should be "-M -Wl")." + +Version 1.5.6beta05 [October 12, 2011] + Speed up png_combine_row() for interlaced images. This reduces the generality + of the code, allowing it to be optimized for Adam7 interlace. The masks + passed to png_combine_row() are now generated internally, avoiding + some code duplication and localizing the interlace handling somewhat. + Align png_struct::row_buf - previously it was always unaligned, caused by + a bug in the code that attempted to align it; the code needs to subtract + one from the pointer to take account of the filter byte prepended to + each row. + Optimized png_combine_row() when rows are aligned. This gains a small + percentage for 16-bit and 32-bit pixels in the typical case where the + output row buffers are appropriately aligned. The optimization was not + previously possible because the png_struct buffer was always misaligned. + Fixed bug in png_write_chunk_header() debug print, introduced in 1.5.6beta01. + +Version 1.5.6beta06 [October 17, 2011] + Removed two redundant tests for uninitialized row. + Fixed a relatively harmless memory overwrite in compressed text writing + with a 1 byte zlib buffer. + Add ability to call png_read_update_info multiple times to pngvalid.c. + Fixes for multiple calls to png_read_update_info. These fixes attend to + most of the errors revealed in pngvalid, however doing the gamma work + twice results in inaccuracies that can't be easily fixed. There is now + a warning in the code if this is going to happen. + Turned on multiple png_read_update_info in pngvalid transform tests. + Prevent libpng from overwriting unused bits at the end of the image when + it is not byte aligned, while reading. Prior to libpng-1.5.6 libpng would + overwrite the partial byte at the end of each row if the row width was not + an exact multiple of 8 bits and the image is not interlaced. + +Version 1.5.6beta07 [October 21, 2011] + Made png_ptr->prev_row an aligned pointer into png_ptr->big_prev_row + (Mans Rullgard). + +Version 1.5.6rc01 [October 26, 2011] + Changed misleading "Missing PLTE before cHRM" warning to "Out of place cHRM" + +Version 1.5.6rc02 [October 27, 2011] + Added LSR() macro to defend against buggy compilers that evaluate non-taken + code branches and complain about out-of-range shifts. + +Version 1.5.6rc03 [October 28, 2011] + Renamed the LSR() macro to PNG_LSR() and added PNG_LSL() macro. + Fixed compiler warnings with Intel and MSYS compilers. The logical shift + fix for Microsoft Visual C is required by other compilers, so this + enables that fix for all compilers when using compile-time constants. + Under MSYS 'byte' is a name declared in a system header file, so we + changed the name of a local variable to avoid the warnings that result. + Added #define PNG_ALIGN_TYPE PNG_ALIGN_NONE to contrib/pngminim/*/pngusr.h + +Version 1.5.6 [November 3, 2011] + No changes. + +Version 1.5.7beta01 [November 4, 2011] + Added support for ARM processor, when decoding all PNG up-filtered rows + and any other-filtered rows with 3 or 4 bytes per pixel (Mans Rullgard). + Fixed bug in pngvalid on early allocation failure; fixed type cast in + pngmem.c; pngvalid would attempt to call png_error() if the allocation + of a png_struct or png_info failed. This would probably have led to a + crash. The pngmem.c implementation of png_malloc() included a cast + to png_size_t which would fail on large allocations on 16-bit systems. + Fix for the preprocessor of the Intel C compiler. The preprocessor + splits adjacent @ signs with a space; this changes the concatenation + token from @-@-@ to PNG_JOIN; that should work with all compiler + preprocessors. + Paeth filter speed improvements from work by Siarhei Siamashka. This + changes the 'Paeth' reconstruction function to improve the GCC code + generation on x86. The changes are only part of the suggested ones; + just the changes that definitely improve speed and remain simple. + The changes also slightly increase the clarity of the code. + +Version 1.5.7beta02 [November 11, 2011] + Check compression_type parameter in png_get_iCCP and remove spurious + casts. The compression_type parameter is always assigned to, so must + be non-NULL. The cast of the profile length potentially truncated the + value unnecessarily on a 16-bit int system, so the cast of the (byte) + compression type to (int) is specified by ANSI-C anyway. + Fixed FP division by zero in pngvalid.c; the 'test_pixel' code left + the sBIT fields in the test pixel as 0, which resulted in a floating + point division by zero which was irrelevant but causes systems where + FP exceptions cause a crash. Added code to pngvalid to turn on FP + exceptions if the appropriate glibc support is there to ensure this is + tested in the future. + Updated scripts/pnglibconf.mak and scripts/makefile.std to handle the + new PNG_JOIN macro. + Added versioning to pnglibconf.h comments. + Simplified read/write API initial version; basic read/write tested on + a variety of images, limited documentation (in the header file.) + Installed more accurate linear to sRGB conversion tables. The slightly + modified tables reduce the number of 16-bit values that + convert to an off-by-one 8-bit value. The "makesRGB.c" code that was used + to generate the tables is now in a contrib/sRGBtables sub-directory. + +Version 1.5.7beta03 [November 17, 2011] + Removed PNG_CONST from the sRGB table declarations in pngpriv.h and png.c + Added run-time detection of NEON support. + Added contrib/libtests; includes simplified API test and timing test and + a color conversion utility for rapid checking of failed 'pngstest' results. + Multiple transform bug fixes plus a work-round for double gamma correction. + libpng does not support more than one transform that requires linear data + at once - if this is tried typically the results is double gamma + correction. Since the simplified APIs can need rgb to gray combined with + a compose operation it is necessary to do one of these outside the main + libpng transform code. This check-in also contains fixes to various bugs + in the simplified APIs themselves and to some bugs in compose and rgb to + gray (on palette) itself. + Fixes for C++ compilation using g++ When libpng source is compiled + using g++. The compiler imposes C++ rules on the C source; thus it + is desirable to make the source work with either C or C++ rules + without throwing away useful error information. This change adds + png_voidcast to allow C semantic (void*) cases or the corresponding + C++ static_cast operation, as appropriate. + Added --noexecstack to assembler file compilation. GCC does not set + this on assembler compilation, even though it does on C compilation. + This creates security issues if assembler code is enabled; the + work-around is to set it by default in the flags for $(CCAS) + Work around compilers that don't support declaration of const data. Some + compilers fault 'extern const' data declarations (because the data is + not initialized); this turns on const-ness only for compilers where + this is known to work. + +Version 1.5.7beta04 [November 17, 2011] + Since the gcc driver does not recognize the --noexecstack flag, we must + use the -Wa prefix to have it passed through to the assembler. + Also removed a duplicate setting of this flag. + Added files that were omitted from the libpng-1.5.7beta03 zip distribution. + +Version 1.5.7beta05 [November 25, 2011] + Removed "zTXt" from warning in generic chunk decompression function. + Validate time settings passed to png_set_tIME() and png_convert_to_rfc1123() + (Frank Busse). Note: This prevented CVE-2015-7981 from affecting + libpng-1.5.7 and later. + Added MINGW support to CMakeLists.txt + Reject invalid compression flag or method when reading the iTXt chunk. + Backed out 'simplified' API changes. The API seems too complex and there + is a lack of consensus or enthusiasm for the proposals. The API also + reveals significant bugs inside libpng (double gamma correction and the + known bug of being unable to retrieve a corrected palette). It seems + better to wait until the bugs, at least, are corrected. + Moved pngvalid.c into contrib/libtests + Rebuilt Makefile.in, configure, etc., with autoconf-2.68 + +Version 1.5.7rc01 [December 1, 2011] + Replaced an "#if" with "#ifdef" in pngrtran.c + Revised #if PNG_DO_BC block in png.c (use #ifdef and add #else) + +Version 1.5.7rc02 [December 5, 2011] + Revised project files and contrib/pngvalid/pngvalid.c to account for + the relocation of pngvalid into contrib/libtests. + Revised pngconf.h to use " __declspec(restrict)" only when MSC_VER >= 1400, + as in libpng-1.5.4. + Put CRLF line endings in the owatcom project files. + +Version 1.5.7rc03 [December 7, 2011] + Updated CMakeLists.txt to account for the relocation of pngvalid.c + +Version 1.5.7 [December 15, 2011] + Minor fixes to pngvalid.c for gcc 4.6.2 compatibility to remove warnings + reported by earlier versions. + Fixed minor memset/sizeof errors in pngvalid.c. + +Version 1.6.0beta01 [December 15, 2011] + Removed machine-generated configure files from the GIT repository (they will + continue to appear in the tarball distributions and in the libpng15 and + earlier GIT branches). + Restored the new 'simplified' API, which was started in libpng-1.5.7beta02 + but later deleted from libpng-1.5.7beta05. + Added example programs for the new 'simplified' API. + Added ANSI-C (C90) headers and require them, and take advantage of the + change. Also fixed some of the projects/* and contrib/* files that needed + updates for libpng16 and the move of pngvalid.c. + With this change the required ANSI-C header files are assumed to exist: the + implementation must provide float.h, limits.h, stdarg.h and stddef.h and + libpng relies on limits.h and stddef.h existing and behaving as defined + (the other two required headers aren't used). Non-ANSI systems that don't + have stddef.h or limits.h will have to provide an appropriate fake + containing the relevant types and #defines. + Dropped support for 16-bit platforms. The use of FAR/far has been eliminated + and the definition of png_alloc_size_t is now controlled by a flag so + that 'small size_t' systems can select it if necessary. Libpng 1.6 may + not currently work on such systems -- it seems likely that it will + ask 'malloc' for more than 65535 bytes with any image that has a + sufficiently large row size (rather than simply failing to read such + images). + New tools directory containing tools used to generate libpng code. + Fixed race conditions in parallel make builds. With higher degrees of + parallelism during 'make' the use of the same temporary file names such + as 'dfn*' can result in a race where a temporary file from one arm of the + build is deleted or overwritten in another arm. This changes the + temporary files for suffix rules to always use $* and ensures that the + non-suffix rules use unique file names. + +Version 1.6.0beta02 [December 21, 2011] + Correct configure builds where build and source directories are separate. + The include path of 'config.h' was erroneously made relative in pngvalid.c + in libpng 1.5.7. + +Version 1.6.0beta03 [December 22, 2011] + Start-up code size improvements, error handler flexibility. These changes + alter how the tricky allocation of the initial png_struct and png_info + structures are handled. png_info is now handled in pretty much the same + way as everything else, except that the allocations handle NULL return + silently. png_struct is changed in a similar way on allocation and on + deallocation a 'safety' error handler is put in place (which should never + be required). The error handler itself is changed to permit mismatches + in the application and libpng error buffer size; however, this means a + silent change to the API to return the jmp_buf if the size doesn't match + the size from the libpng compilation; libpng now allocates the memory and + this may fail. Overall these changes result in slight code size + reductions; however, this is a reduction in code that is always executed + so is particularly valuable. Overall on a 64-bit system the libpng DLL + decreases in code size by 1733 bytes. pngerror.o increases in size by + about 465 bytes because of the new functionality. + Added png_convert_to_rfc1123_buffer() and deprecated png_convert_to_rfc1123() + to avoid including a spurious buffer in the png_struct. + +Version 1.6.0beta04 [December 30, 2011] + Regenerated configure scripts with automake-1.11.2 + Eliminated png_info_destroy(). It is now used only in png.c and only calls + one other internal function and memset(). + Enabled png_get_sCAL_fixed() if floating point APIs are enabled. Previously + it was disabled whenever internal fixed point arithmetic was selected, + which meant it didn't exist even on systems where FP was available but not + preferred. + Added pngvalid.c compile time checks for const APIs. + Implemented 'restrict' for png_info and png_struct. Because of the way + libpng works both png_info and png_struct are always accessed via a + single pointer. This means adding C99 'restrict' to the pointer gives + the compiler some opportunity to optimize the code. This change allows + that. + Moved AC_MSG_CHECKING([if libraries can be versioned]) later to the proper + location in configure.ac (Gilles Espinasse). + Changed png_memcpy to C assignment where appropriate. Changed all those + uses of png_memcpy that were doing a simple assignment to assignments + (all those cases where the thing being copied is a non-array C L-value). + Added some error checking to png_set_*() routines. + Removed the reference to the non-exported function png_memcpy() from + example.c. + Fixed the Visual C 64-bit build - it requires jmp_buf to be aligned, but + it had become misaligned. + Revised contrib/pngminus/pnm2png.c to avoid warnings when png_uint_32 + and unsigned long are of different sizes. + +Version 1.6.0beta05 [January 15, 2012] + Updated manual with description of the simplified API (copied from png.h) + Fix bug in pngerror.c: some long warnings were being improperly truncated + (CVE-2011-3464, bug introduced in libpng-1.5.3beta05). + +Version 1.6.0beta06 [January 24, 2012] + Added palette support to the simplified APIs. This commit + changes some of the macro definitions in png.h, app code + may need corresponding changes. + Increased the formatted warning buffer to 192 bytes. + Added color-map support to simplified API. This is an initial version for + review; the documentation has not yet been updated. + Fixed Min/GW uninstall to remove libpng.dll.a + +Version 1.6.0beta07 [January 28, 2012] + Eliminated Intel icc/icl compiler warnings. The Intel (GCC derived) + compiler issues slightly different warnings from those issued by the + current vesions of GCC. This eliminates those warnings by + adding/removing casts and small code rewrites. + Updated configure.ac from autoupdate: added --enable-werror option. + Also some layout regularization and removal of introduced tab characters + (replaced with 3-character indentation). Obsolete macros identified by + autoupdate have been removed; the replacements are all in 2.59 so + the pre-req hasn't been changed. --enable-werror checks for support + for -Werror (or the given argument) in the compiler. This mimics the + gcc configure option by allowing -Werror to be turned on safely; without + the option the tests written in configure itself fail compilation because + they cause compiler warnings. + Rewrote autogen.sh to run autoreconf instead of running tools one-by-one. + Conditionalize the install rules for MINGW and CYGWIN in CMakeLists.txt and + set CMAKE_LIBRARY_OUTPUT_DIRECTORY to "lib" on all platforms (C. Yapp). + Freeze libtool files in the 'scripts' directory. This version of autogen.sh + attempts to dissuade people from running it when it is not, or should not, + be necessary. In fact, autogen.sh does not work when run in a libpng + directory extracted from a tar distribution anymore. You must run it in + a GIT clone instead. + Added two images to contrib/pngsuite (1-bit and 2-bit transparent grayscale), + and renamed three whose names were inconsistent with those in + pngsuite/README.txt. + +Version 1.6.0beta08 [February 1, 2012] + Fixed Image::colormap misalignment in pngstest.c + Check libtool/libtoolize version number (2.4.2) in configure.ac + Divide test-pngstest.sh into separate pngstest runs for basic and + transparent images. + Moved automake options to AM_INIT_AUTOMAKE in configure.ac + Added color-tests, silent-rules (Not yet implemented in Makefile.am) and + version checking to configure.ac + Improved pngstest speed by not doing redundant tests and add const to + the background parameter of png_image_finish_read. The --background + option is now done automagically only when required, so that commandline + option no longer exists. + Cleaned up pngpriv.h to consistently declare all functions and data. + Also eliminated PNG_CONST_DATA, which is apparently not needed but we + can't be sure until it is gone. + Added symbol prefixing that allows all the libpng external symbols + to be prefixed (suggested by Reuben Hawkins). + Updated "ftbb*.png" list in the owatcom and vstudio projects. + Fixed 'prefix' builds on clean systems. The generation of pngprefix.h + should not require itself. + Updated INSTALL to explain that autogen.sh must be run in a GIT clone, + not in a libpng directory extracted from a tar distribution. + +Version 1.6.0beta09 [February 1, 2012] + Reverted the prebuilt configure files to libpng-1.6.0beta05 condition. + +Version 1.6.0beta10 [February 3, 2012] + Added Z_SOLO for zlib-1.2.6+ and correct pngstest tests + Updated list of test images in CMakeLists.txt + Updated the prebuilt configure files to current condition. + Revised INSTALL information about autogen.sh; it works in tar distributions. + +Version 1.6.0beta11 [February 16, 2012] + Fix character count in pngstest command in projects/owatcom/pngstest.tgt + Revised test-pngstest.sh to report PASS/FAIL for each image. + Updated documentation about the simplified API. + Corrected estimate of error in libpng png_set_rgb_to_gray API. The API is + extremely inaccurate for sRGB conversions because it uses an 8-bit + intermediate linear value and it does not use the sRGB transform, so it + suffers from the known instability in gamma transforms for values close + to 0 (see Poynton). The net result is that the calculation has a maximum + error of 14.99/255; 0.5/255^(1/2.2). pngstest now uses 15 for the + permitted 8-bit error. This may still not be enough because of arithmetic + error. + Removed some unused arrays (with #ifdef) from png_read_push_finish_row(). + Fixed a memory overwrite bug in simplified read of RGB PNG with + non-linear gamma Also bugs in the error checking in pngread.c and changed + quite a lot of the checks in pngstest.c to be correct; either correctly + written or not over-optimistic. The pngstest changes are insufficient to + allow all possible RGB transforms to be passed; pngstest cmppixel needs + to be rewritten to make it clearer which errors it allows and then changed + to permit known inaccuracies. + Removed tests for no-longer-used *_EMPTY_PLTE_SUPPORTED from pngstruct.h + Fixed fixed/float API export conditionals. 1) If FIXED_POINT or + FLOATING_POINT options were switched off, png.h ended up with lone ';' + characters. This is not valid ANSI-C outside a function. The ';' + characters have been moved inside the definition of PNG_FP_EXPORT and + PNG_FIXED_EXPORT. 2) If either option was switched off, the declaration + of the corresponding functions were completely omitted, even though some + of them are still used internally. The result is still valid, but + produces warnings from gcc with some warning options (including -Wall). The + fix is to cause png.h to declare the functions with PNG_INTERNAL_FUNCTION + when png.h is included from pngpriv.h. + Check for invalid palette index while reading paletted PNG. When one is + found, issue a warning and increase png_ptr->num_palette accordingly. + Apps are responsible for checking to see if that happened. + +Version 1.6.0beta12 [February 18, 2012] + Do not increase num_palette on invalid_index. + Relocated check for invalid palette index to pngrtran.c, after unpacking + the sub-8-bit pixels. + Fixed CVE-2011-3026 buffer overrun bug. This bug was introduced when + iCCP chunk support was added at libpng-1.0.6. Deal more correctly with the + test on iCCP chunk length. Also removed spurious casts that may hide + problems on 16-bit systems. + +Version 1.6.0beta13 [February 24, 2012] + Eliminated redundant png_push_read_tEXt|zTXt|iTXt|unknown code from + pngpread.c and use the sequential png_handle_tEXt, etc., in pngrutil.c; + now that png_ptr->buffer is inaccessible to applications, the special + handling is no longer useful. + Added PNG_SAFE_LIMITS feature to pnglibconf.dfa, pngpriv.h, and new + pngusr.dfa to reset the user limits to safe ones if PNG_SAFE_LIMITS is + defined. To enable, use "CPPFLAGS=-DPNG_SAFE_LIMITS_SUPPORTED=1" on the + configure command or put #define PNG_SAFE_LIMITS_SUPPORTED in + pnglibconf.h.prebuilt and pnglibconf.h. + +Version 1.6.0beta14 [February 27, 2012] + Added information about the new limits in the manual. + Updated Makefile.in + +Version 1.6.0beta15 [March 2, 2012] + Removed unused "current_text" members of png_struct and the png_free() + of png_ptr->current_text from pngread.c + Rewrote pngstest.c for substantial speed improvement. + Fixed transparent pixel and 16-bit rgb tests in pngstest and removed a + spurious check in pngwrite.c + Added PNG_IMAGE_FLAG_FAST for the benefit of applications that store + intermediate files, or intermediate in-memory data, while processing + image data with the simplified API. The option makes the files larger + but faster to write and read. pngstest now uses this by default; this + can be disabled with the --slow option. + Improved pngstest fine tuning of error numbers, new test file generator. + The generator generates images that test the full range of sample values, + allow the error numbers in pngstest to be tuned and checked. makepng + also allows generation of images with extra chunks, although this is + still work-in-progress. + Added check for invalid palette index while reading. + Fixed some bugs in ICC profile writing. The code should now accept + all potentially valid ICC profiles and reject obviously invalid ones. + It now uses png_error() to do so rather than casually writing a PNG + without the necessary color data. + Removed whitespace from the end of lines in all source files and scripts. + +Version 1.6.0beta16 [March 6, 2012] + Relocated palette-index checking function from pngrutil.c to pngtrans.c + Added palette-index checking while writing. + Changed png_inflate() and calling routines to avoid overflow problems. + This is an intermediate check-in that solves the immediate problems and + introduces one performance improvement (avoiding a copy via png_ptr->zbuf.) + Further changes will be made to make ICC profile handling more secure. + Fixed build warnings (MSVC, GCC, GCC v3). Cygwin GCC with default options + declares 'index' as a global, causing a warning if it is used as a local + variable. GCC 64-bit warns about assigning a (size_t) (unsigned 64-bit) + to an (int) (signed 32-bit). MSVC, however, warns about using the + unary '-' operator on an unsigned value (even though it is well defined + by ANSI-C to be ~x+1). The padding calculation was changed to use a + different method. Removed the tests on png_ptr->pass. + Added contrib/libtests/tarith.c to test internal arithmetic functions from + png.c. This is a libpng maintainer program used to validate changes to the + internal arithmetic functions. + Made read 'inflate' handling like write 'deflate' handling. The read + code now claims and releases png_ptr->zstream, like the write code. + The bug whereby the progressive reader failed to release the zstream + is now fixed, all initialization is delayed, and the code checks for + changed parameters on deflate rather than always calling + deflatedEnd/deflateInit. + Validate the zTXt strings in pngvalid. + Added code to validate the windowBits value passed to deflateInit2(). + If the call to deflateInit2() is wrong a png_warning will be issued + (in fact this is harmless, but the PNG data produced may be sub-optimal). + +Version 1.6.0beta17 [March 10, 2012] + Fixed PNG_LIBPNG_BUILD_BASE_TYPE definition. + Reject all iCCP chunks after the first, even if the first one is invalid. + Deflate/inflate was reworked to move common zlib calls into single + functions [rw]util.c. A new shared keyword check routine was also added + and the 'zbuf' is no longer allocated on progressive read. It is now + possible to call png_inflate() incrementally. A warning is no longer + issued if the language tag or translated keyword in the iTXt chunk + has zero length. + If benign errors are disabled use maximum window on ancillary inflate. + This works round a bug introduced in 1.5.4 where compressed ancillary + chunks could end up with a too-small windowBits value in the deflate + header. + +Version 1.6.0beta18 [March 16, 2012] + Issue a png_benign_error() instead of png_warning() about bad palette index. + In pngtest, treat benign errors as errors if "-strict" is present. + Fixed an off-by-one error in the palette index checking function. + Fixed a compiler warning under Cygwin (Windows-7, 32-bit system) + Revised example.c to put text strings in a temporary character array + instead of directly assigning string constants to png_textp members. + This avoids compiler warnings when -Wwrite-strings is enabled. + Added output flushing to aid debugging under Visual Studio. Unfortunately + this is necessary because the VS2010 output window otherwise simply loses + the error messages on error (they weren't flushed to the window before + the process exited, apparently!) + Added configuration support for benign errors and changed the read + default. Also changed some warnings in the iCCP and sRGB handling + from to benign errors. Configuration now makes read benign + errors warnings and write benign errors to errors by default (thus + changing the behavior on read). The simplified API always forces + read benign errors to warnings (regardless of the system default, unless + this is disabled in which case the simplified API can't be built.) + +Version 1.6.0beta19 [March 18, 2012] + Work around for duplicate row start calls; added warning messages. + This turns on PNG_FLAG_DETECT_UNINITIALIZED to detect app code that + fails to call one of the 'start' routines (not enabled in libpng-1.5 + because it is technically an API change, since it did normally work + before.) It also makes duplicate calls to png_read_start_row (an + internal function called at the start of the image read) benign, as + they were before changes to use png_inflate_claim. Somehow webkit is + causing this to happen; this is probably a mis-feature in the zlib + changes so this commit is only a work-round. + Removed erroneous setting of DETECT_UNINITIALIZED and added more + checks. The code now does a png_error if an attempt is made to do the + row initialization twice; this is an application error and it has + serious consequences because the transform data in png_struct is + changed by each call. + Added application error reporting and added chunk names to read + benign errors; also added --strict to pngstest - not enabled + yet because a warning is produced. + Avoid the double gamma correction warning in the simplified API. + This allows the --strict option to pass in the pngstest checks + +Version 1.6.0beta20 [March 29, 2012] + Changed chunk handler warnings into benign errors, incrementally load iCCP + Added checksum-icc.c to contrib/tools + Prevent PNG_EXPAND+PNG_SHIFT doing the shift twice. + Recognize known sRGB ICC profiles while reading; prefer writing the + iCCP profile over writing the sRGB chunk, controlled by the + PNG_sRGB_PROFILE_CHECKS option. + Revised png_set_text_2() to avoid potential memory corruption (fixes + CVE-2011-3048, also known as CVE-2012-3425). + +Version 1.6.0beta21 [April 27, 2012] + Revised scripts/makefile.darwin: use system zlib; remove quotes around + architecture list; add missing ppc architecture; add architecture options + to shared library link; don't try to create a shared lib based on missing + RELEASE variable. + Enable png_set_check_for_invalid_index() for both read and write. + Removed #ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED in pngpriv.h around + declaration of png_handle_unknown(). + Added -lssp_nonshared in a comment in scripts/makefile.freebsd + and changed deprecated NOOBJ and NOPROFILE to NO_OBJ and NO_PROFILE. + +Version 1.6.0beta22 [May 23, 2012] + Removed need for -Wno-cast-align with clang. clang correctly warns on + alignment increasing pointer casts when -Wcast-align is passed. This + fixes the cases that clang warns about either by eliminating the + casts from png_bytep to png_uint_16p (pngread.c), or, for pngrutil.c + where the cast is previously verified or pngstest.c where it is OK, by + introducing new png_aligncast macros to do the cast in a way that clang + accepts. + +Version 1.6.0beta23 [June 6, 2012] + Revised CMakeLists.txt to not attempt to make a symlink under mingw. + Made fixes for new optimization warnings from gcc 4.7.0. The compiler + performs an optimization which is safe; however it then warns about it. + Changing the type of 'palette_number' in pngvalid.c removes the warning. + Do not depend upon a GCC feature macro being available for use in generating + the linker mapfile symbol prefix. + Improved performance of new do_check_palette_indexes() function (only + update the value when it actually increases, move test for whether + the check is wanted out of the function. + +Version 1.6.0beta24 [June 7, 2012] + Don't check palette indexes if num_palette is 0 (as it can be in MNG files). + +Version 1.6.0beta25 [June 16, 2012] + Revised png_set_keep_unknown_chunks() so num_chunks < 0 means ignore all + unknown chunks and all known chunks except for IHDR, PLTE, tRNS, IDAT, + and IEND. Previously it only meant ignore all unknown chunks, the + same as num_chunks == 0. Revised png_image_skip_unused_chunks() to + provide a list of chunks to be processed instead of a list of chunks to + ignore. Revised contrib/gregbook/readpng2.c accordingly. + +Version 1.6.0beta26 [July 10, 2012] + Removed scripts/makefile.cegcc from the *.zip and *.7z distributions; it + depends on configure, which is not included in those archives. + Moved scripts/chkfmt to contrib/tools. + Changed "a+w" to "u+w" in Makefile.in to fix CVE-2012-3386. + +Version 1.6.0beta27 [August 11, 2012] + Do not compile PNG_DEPRECATED, PNG_ALLOC and PNG_PRIVATE when __GNUC__ < 3. + Do not use __restrict when GNUC is <= 3.1 + Removed references to png_zalloc() and png_zfree() from the manual. + Fixed configurations where floating point is completely disabled. Because + of the changes to support symbol prefixing PNG_INTERNAL_FUNCTION declares + floating point APIs during libpng builds even if they are completely + disabled. This requires the png floating point types (png_double*) to be + declared even though the functions are never actually defined. This + change provides a dummy definition so that the declarations work, yet any + implementation will fail to compile because of an incomplete type. + Re-eliminated the use of strcpy() in pngtest.c. An unnecessary use of + strcpy() was accidentally re-introduced in libpng16; this change replaces + it with strncpy(). + Eliminated use of png_sizeof(); use sizeof() instead. + Use a consistent style for (sizeof type) and (sizeof (array)) + Cleanup of png_set_filler(). This function does very different things on + read and write. In libpng 1.6 the two cases can be distinguished and + considerable code cleanup, and extra error checking, is possible. This + makes calls on the write side that have no effect be ignored with a + png_app_error(), which can be disabled in the app using + png_set_benign_errors(), and removes the spurious use of usr_channels + on the read side. + Insist on autotools 1.12.1 for git builds because there are security issues + with 1.12 and insisting on anything less would allow 1.12 to be used. + Removed info_ptr->signature[8] from WRITE-only builds. + Add some conditions for compiling png_fixed(). This is a small function + but it requires "-lm" on some platforms. + Cause pngtest --strict to fail on any warning from libpng (not just errors) + and cause it not to fail at the comparison step if libpng lacks support + for writing chunks that it reads from the input (currently only implemented + for compressed text chunks). + Make all three "make check" test programs work without READ or WRITE support. + Now "make check" will succeed even if libpng is compiled with -DPNG_NO_READ + or -DPNG_NO_WRITE. The tests performed are reduced, but the basic reading + and writing of a PNG file is always tested by one or more of the tests. + Consistently use strlen(), memset(), memcpy(), and memcmp() instead of the + png_strlen(), png_memset(), png_memcpy(), and png_memcmp() macros. + Removed the png_sizeof(), png_strlen(), png_memset(), png_memcpy(), and + png_memcmp() macros. + Work around gcc 3.x and Microsoft Visual Studio 2010 complaints. Both object + to the split initialization of num_chunks. + +Version 1.6.0beta28 [August 29, 2012] + Unknown handling fixes and clean up. This adds more correct option + control of the unknown handling, corrects the pre-existing bug where + the per-chunk 'keep' setting is ignored and makes it possible to skip + IDAT chunks in the sequential reader (broken in earlier 1.6 versions). + There is a new test program, test-unknown.c, which is a work in progress + (not currently part of the test suite). Comments in the header files now + explain how the unknown handling works. + Allow fine grain control of unknown chunk APIs. This change allows + png_set_keep_unknown_chunks() to be turned off if not required and causes + both read and write to behave appropriately (on read this is only possible + if the user callback is used to handle unknown chunks). The change + also removes the support for storing unknown chunks in the info_struct + if the only unknown handling enabled is via the callback, allowing libpng + to be configured with callback reading and none of the unnecessary code. + Corrected fix for unknown handling in pngtest. This reinstates the + libpng handling of unknown chunks other than vpAg and sTER (including + unsafe-to-copy chunks which were dropped before) and eliminates the + repositioning of vpAg and sTER in pngtest.png by changing pngtest.png + (so the chunks are where libpng would put them). + Added "tunknown" test and corrected a logic error in png_handle_unknown() + when SAVE support is absent. Moved the shell test scripts for + contrib/libtests from the libpng top directory to contrib/libtests. + png_handle_unknown() must always read or skip the chunk, if + SAVE_UNKNOWN_CHUNKS is turned off *and* the application does not set + a user callback an unknown chunk will not be read, leading to a read + error, which was revealed by the "tunknown" test. + Cleaned up and corrected ICC profile handling. + contrib/libtests/makepng: corrected 'rgb' and 'gray' cases. profile_error + messages could be truncated; made a correct buffer size calculation and + adjusted pngerror.c appropriately. png_icc_check_* checking improved; + changed the functions to receive the correct color type of the PNG on read + or write and check that it matches the color space of the profile (despite + what the comments said before, there is danger in assuming the app will + cope correctly with an RGB profile on a grayscale image and, since it + violates the PNG spec, allowing it is certain to produce inconsistent + app behavior and might even cause app crashes.) Check that profiles + contain the tags needed to process the PNG (tags all required by the ICC + spec). Removed unused PNG_STATIC from pngpriv.h. + +Version 1.6.0beta29 [September 4, 2012] + Fixed the simplified API example programs to add the *colormap parameter + to several of he API and improved the error message if the version field + is not set. + Added contrib/examples/* to the *.zip and *.7z distributions. + Updated simplified API synopses and description of the png_image structure + in the manual. + Made makepng and pngtest produce identical PNGs, add "--relaxed" option + to pngtest. The "--relaxed" option turns off the benign errors that are + enabled by default in pre-RC builds. makepng can now write ICC profiles + where the length has not been extended to a multiple of 4, and pngtest + now intercepts all libpng errors, allowing the previously-introduced + "--strict test" on no warnings to actually work. + Improved ICC profile handling including cHRM chunk generation and fixed + Cygwin+MSVC build errors. The ICC profile handling now includes more + checking. Several errors that caused rejection of the profile are now + handled with a warning in such a way that the invalid profiles will be + read by default in release (but not pre-RC) builds but will not be + written by default. The easy part of handling the cHRM chunk is written, + where the ICC profile contains the required data. The more difficult + part plus guessing a gAMA value requires code to pass selected RGB values + through the profile. + +Version 1.6.0beta30 [October 24, 2012] + Changed ICC profile matrix/vector types to not depend on array type rules. + By the ANSI-C standard the new types should be identical to the previous + versions, and all known versions of gcc tested with the previous versions + except for GCC-4.2.1 work with this version. The change makes the ANSI-C + rule that const applied to an array of elements applies instead to the + elements in the array moot by explicitly applying const to the base + elements of the png_icc_matrix and png_icc_vector types. The accidental + (harmless) 'const' previously applied to the parameters of two of the + functions have also been removed. + Added a work around for GCC 4.2 optimization bug. + Marked the broken (bad white point) original HP sRGB profiles correctly and + correct comments. + Added -DZ_SOLO to contrib/pngminim/*/makefile to work with zlib-1.2.7 + Use /MDd for vstudio debug builds. Also added pngunkown to the vstudio + builds, fixed build errors and corrected a minor exit code error in + pngvalid if the 'touch' file name is invalid. + Add updated WARNING file to projects/vstudio from libpng 1.5/vstudio + Fixed build when using #define PNG_NO_READ_GAMMA in png_do_compose() in + pngrtran.c (Domani Hannes). + +Version 1.6.0beta31 [November 1, 2012] + Undid the erroneous change to vstudio/pngvalid build in libpng-1.6.0beta30. + Made pngvalid so that it will build outside the libpng source tree. + Made builds -DPNG_NO_READ_GAMMA compile (the unit tests still fail). + Made PNG_NO_READ_GAMMA switch off interfaces that depend on READ_GAMMA. + Prior to 1.6.0 switching off READ_GAMMA did unpredictable things to the + interfaces that use it (specifically, png_do_background in 1.4 would + simply display composite for grayscale images but do composition + with the incorrect arithmetic for color ones). In 1.6 the semantic + of -DPNG_NO_READ_GAMMA is changed to simply disable any interface that + depends on it; this obliges people who set it to consider whether they + really want it off if they happen to use any of the interfaces in + question (typically most users who disable it won't). + Fixed GUIDs in projects/vstudio. Some were duplicated or missing, + resulting in VS2010 having to update the files. + Removed non-working ICC profile support code that was mostly added to + libpng-1.6.0beta29 and beta30. There was too much code for too little + gain; implementing full ICC color correction may be desirable but is left + up to applications. + +Version 1.6.0beta32 [November 25, 2012] + Fixed an intermittent SEGV in pngstest due to an uninitialized array element. + Added the ability for contrib/libtests/makepng.c to make a PNG with just one + color. This is useful for debugging pngstest color inaccuracy reports. + Fixed error checking in the simplified write API (Olaf van der Spek) + Made png_user_version_check() ok to use with libpng version 1.10.x and later. + +Version 1.6.0beta33 [December 15, 2012] + Fixed typo in png.c (PNG_SET_CHUNK_MALLOC_MAX should be PNG_CHUNK_MALLOC_MAX) + that causes the MALLOC_MAX limit not to work (John Bowler) + Change png_warning() to png_app_error() in pngwrite.c and comment the + fall-through condition. + Change png_warning() to png_app_warning() in png_write_tRNS(). + Rearranged the ARM-NEON optimizations: Isolated the machine specific code + to the hardware subdirectory and added comments to pngrutil.c so that + implementors of other optimizations know what to do. + Fixed cases of unquoted DESTDIR in Makefile.am + Rebuilt Makefile.in, etc., with autoconf-2.69 and automake-1.12.5. + +Version 1.6.0beta34 [December 19, 2012] + Cleaned up whitespace in the synopsis portion of the manpage "libpng.3" + Disassembled the version number in scripts/options.awk (necessary for + building on SunOs). + +Version 1.6.0beta35 [December 23, 2012] + Made default Zlib compression settings be configurable. This adds #defines to + pnglibconf.h to control the defaults. + Fixed Windows build issues, enabled ARM compilation. Various warnings issued + by earlier versions of GCC fixed for Cygwin and Min/GW (which both use old + GCCs.) ARM support is enabled by default in zlib.props (unsupported by + Microsoft) and ARM compilation is made possible by deleting the check for + x86. The test programs cannot be run because they are not signed. + +Version 1.6.0beta36 [January 2, 2013] + Discontinued distributing libpng-1.x.x.tar.bz2. + Discontinued distributing libpng-1.7.0-1.6.0-diff.txt and similar. + Rebuilt configure with autoconf-2.69 (inadvertently not done in beta33) + Fixed 'make distcheck' on SUN OS - libpng.so was not being removed + +Version 1.6.0beta37 [January 10, 2013] + Fixed conceivable but difficult to repro overflow. Also added two test + programs to generate and test a PNG which should have the problem. + +Version 1.6.0beta39 [January 19, 2013] + Again corrected attempt at overflow detection in png_set_unknown_chunks() + (CVE-2013-7353). Added overflow detection in png_set_sPLT() and + png_set_text_2() (CVE-2013-7354). + +Version 1.6.0beta40 [January 20, 2013] + Use consistent handling of overflows in text, sPLT and unknown png_set_* APIs + +Version 1.6.0rc01 [January 26, 2013] + No changes. + +Version 1.6.0rc02 [February 4, 2013] + Added png_get_palette_max() function. + +Version 1.6.0rc03 [February 5, 2013] + Fixed the png_get_palette_max API. + +Version 1.6.0rc04 [February 7, 2013] + Turn serial tests back on (recently turned off by autotools upgrade). + +Version 1.6.0rc05 [February 8, 2013] + Update manual about png_get_palette_max(). + +Version 1.6.0rc06 [February 9, 2013] + Fixed missing dependency in --prefix builds The intermediate + internal 'prefix.h' file can only be generated correctly after + pnglibconf.h, however the dependency was not in Makefile.am. The + symptoms are unpredictable depending on the order make chooses to + build pngprefix.h and pnglibconf.h, often the error goes unnoticed + because there is a system pnglibconf.h to use instead. + +Version 1.6.0rc07 [February 10, 2013] + Enclosed the new png_get_palette_max in #ifdef PNG_GET_PALETTE_MAX_SUPPORTED + block, and revised pnglibconf.h and pnglibconf.h.prebuilt accordingly. + +Version 1.6.0rc08 [February 10, 2013] + Fix typo in png.h #ifdef + +Version 1.6.0 [February 14, 2013] + No changes. + +Version 1.6.1beta01 [February 16, 2013] + Made symbol prefixing work with the ARM neon optimizations. Also allow + pngpriv.h to be included for preprocessor definitions only, so it can + be used in non-C/C++ files. Back ported from libpng 1.7. + Made sRGB check numbers consistent. + Ported libpng 1.5 options.awk/dfn file handling to 1.6, fixed one bug. + Removed cc -E workround, corrected png_get_palette_max API Tested on + SUN OS cc 5.9, which demonstrates the tokenization problem previously + avoided by using /lib/cpp. Since all .dfn output is now protected in + double quotes unless it is to be macro substituted the fix should + work everywhere. + Enabled parallel tests - back ported from libpng-1.7. + scripts/pnglibconf.dfa formatting improvements back ported from libpng17. + Fixed a race condition in the creation of the build 'scripts' directory + while building with a parallel make. + Use approved/supported Android method to check for NEON, use Linux/POSIX + 1003.1 API to check /proc/self/auxv avoiding buffer allocation and other + library calls (ported from libpng15). + +Version 1.6.1beta02 [February 19, 2013] + Use parentheses more consistently in "#if defined(MACRO)" tests. + Folded long lines. + Reenabled code to allow zero length PLTE chunks for MNG. + +Version 1.6.1beta03 [February 22, 2013] + Fixed ALIGNED_MEMORY support. + Added a new configure option: + --enable-arm-neon=always will stop the run-time checks. New checks + within arm/arm_init.c will cause the code not to be compiled unless + __ARM_NEON__ is set. This should make it fail safe (if someone asks + for it on then the build will fail if it can't be done.) + Updated the INSTALL document. + +Version 1.6.1beta04 [February 27, 2013] + Revised INSTALL to recommend using CPPFLAGS instead of INCLUDES. + Revised scripts/makefile.freebsd to respect ZLIBLIB and ZLIBINC. + Revised scripts/dfn.awk to work with the buggy MSYS awk that has trouble + with CRLF line endings. + +Version 1.6.1beta05 [March 1, 2013] + Avoid a possible memory leak in contrib/gregbook/readpng.c + +Version 1.6.1beta06 [March 4, 2013] + Better documentation of unknown handling API interactions. + Corrected Android builds and corrected libpng.vers with symbol + prefixing. It also makes those tests compile and link on Android. + Added an API png_set_option() to set optimization options externally, + providing an alternative and general solution for the non-portable + run-time tests used by the ARM Neon code, using the PNG_ARM_NEON option. + The order of settings vs options in pnglibconf.h is reversed to allow + settings to depend on options and options can now set (or override) the + defaults for settings. + +Version 1.6.1beta07 [March 7, 2013] + Corrected simplified API default gamma for color-mapped output, added + a flag to change default. In 1.6.0 when the simplified API was used + to produce color-mapped output from an input image with no gamma + information the gamma assumed for the input could be different from + that assumed for non-color-mapped output. In particular 16-bit depth + input files were assumed to be sRGB encoded, whereas in the 'direct' + case they were assumed to have linear data. This was an error. The + fix makes the simplified API treat all input files the same way and + adds a new flag to the png_image::flags member to allow the + application/user to specify that 16-bit files contain sRGB data + rather than the default linear. + Fixed bugs in the pngpixel and makepng test programs. + +Version 1.6.1beta08 [March 7, 2013] + Fixed CMakelists.txt to allow building a single variant of the library + (Claudio Bley): + Introduced a PNG_LIB_TARGETS variable that lists all activated library + targets. It is an error if this variable ends up empty, ie. you have + to build at least one library variant. + Made the *_COPY targets only depend on library targets actually being build. + Use PNG_LIB_TARGETS to unify a code path. + Changed the CREATE_SYMLINK macro to expect the full path to a file as the + first argument. When symlinking the filename component of that path is + determined and used as the link target. + Use copy_if_different in the CREATE_SYMLINK macro. + +Version 1.6.1beta09 [March 13, 2013] + Eliminated two warnings from the Intel C compiler. The warnings are + technically valid, although a reasonable treatment of division would + show it to be incorrect. + +Version 1.6.1rc01 [March 21, 2013] + No changes. + +Version 1.6.1 [March 28, 2013] + No changes. + +Version 1.6.2beta01 [April 14, 2013] + Updated documentation of 1.5.x to 1.6.x changes in iCCP chunk handling. + Fixed incorrect warning of excess deflate data. End condition - the + warning would be produced if the end of the deflate stream wasn't read + in the last row. The warning is harmless. + Corrected the test on user transform changes on read. It was in the + png_set of the transform function, but that doesn't matter unless the + transform function changes the rowbuf size, and that is only valid if + transform_info is called. + Corrected a misplaced closing bracket in contrib/libtests/pngvalid.c + (Flavio Medeiros). + Corrected length written to uncompressed iTXt chunks (Samuli Suominen). + Bug was introduced in libpng-1.6.0. + +Version 1.6.2rc01 [April 18, 2013] + Added contrib/tools/fixitxt.c, to repair the erroneous iTXt chunk length + written by libpng-1.6.0 and 1.6.1. + Disallow storing sRGB information when the sRGB is not supported. + +Version 1.6.2rc02 [April 18, 2013] + Merge pngtest.c with libpng-1.7.0 + +Version 1.6.2rc03 [April 22, 2013] + Trivial spelling cleanup. + +Version 1.6.2rc04 and 1.6.2rc05 [omitted] + +Version 1.6.2rc06 [April 24, 2013] + Reverted to version 1.6.2rc03. Recent changes to arm/neon support + have been ported to libpng-1.7.0beta09 and will reappear in version + 1.6.3beta01. + +Version 1.6.2 [April 25, 2013] + No changes. + +Version 1.6.3beta01 [April 25, 2013] + Revised stack marking in arm/filter_neon.S and configure.ac. + Ensure that NEON filter stuff is completely disabled when switched 'off'. + Previously the ARM NEON specific files were still built if the option + was switched 'off' as opposed to being explicitly disabled. + +Version 1.6.3beta02 [April 26, 2013] + Test for 'arm*' not just 'arm' in the host_cpu configure variable. + Rebuilt the configure scripts. + +Version 1.6.3beta03 [April 30, 2013] + Expanded manual paragraph about writing private chunks, particularly + the need to call png_set_keep_unknown_chunks() when writing them. + Avoid dereferencing NULL pointer possibly returned from + png_create_write_struct() (Andrew Church). + +Version 1.6.3beta05 [May 9, 2013] + Calculate our own zlib windowBits when decoding rather than trusting the + CMF bytes in the PNG datastream. + Added an option to force maximum window size for inflating, which was + the behavior of libpng15 and earlier, via a new PNG_MAXIMUM_INFLATE_WINDOW + option for png_set_options(). + Added png-fix-itxt and png-fix-too-far-back to the built programs and + removed warnings from the source code and timepng that are revealed as + a result. + Detect wrong libpng versions linked to png-fix-too-far-back, which currently + only works with libpng versions that can be made to reliably fail when + the deflate data contains an out-of-window reference. This means only + 1.6 and later. + Fixed gnu issues: g++ needs a static_cast, gcc 4.4.7 has a broken warning + message which it is easier to work round than ignore. + Updated contrib/pngminus/pnm2png.c (Paul Stewart): + Check for EOF + Ignore "#" delimited comments in input file to pnm2png.c. + Fixed whitespace handling + Added a call to png_set_packing() + Initialize dimension values so if sscanf fails at least we have known + invalid values. + Attempt to detect configuration issues with png-fix-too-far-back, which + requires both the correct libpng and the correct zlib to function + correctly. + Check ZLIB_VERNUM for mismatches, enclose #error in quotes + Added information in the documentation about problems with and fixes for + the bad CRC and bad iTXt chunk situations. + +Version 1.6.3beta06 [May 12, 2013] + Allow contrib/pngminus/pnm2png.c to compile without WRITE_INVERT and + WRITE_PACK supported (writes error message that it can't read P1 or + P4 PBM files). + Improved png-fix-too-far-back usage message, added --suffix option. + Revised contrib/pngminim/*/makefile to generate pnglibconf.h with the + right zlib header files. + Separated CPPFLAGS and CFLAGS in contrib/pngminim/*/makefile + +Version 1.6.3beta07 [June 8, 2013] + Removed a redundant test in png_set_IHDR(). + Added set(CMAKE_CONFIGURATION_TYPES ...) to CMakeLists.txt (Andrew Hundt) + Deleted set(CMAKE_BUILD_TYPE) block from CMakeLists.txt + Enclose the prototypes for the simplified write API in + #ifdef PNG_STDIO_SUPPORTED/#endif + Make ARM NEON support work at compile time (not just configure time). + This moves the test on __ARM_NEON__ into pngconf.h to avoid issues when + using a compiler that compiles for multiple architectures at one time. + Removed PNG_FILTER_OPTIMIZATIONS and PNG_ARM_NEON_SUPPORTED from + pnglibconf.h, allowing more of the decisions to be made internally + (pngpriv.h) during the compile. Without this, symbol prefixing is broken + under certain circumstances on ARM platforms. Now only the API parts of + the optimizations ('check' vs 'api') are exposed in the public header files + except that the new setting PNG_ARM_NEON_OPT documents how libpng makes the + decision about whether or not to use the optimizations. + Protect symbol prefixing against CC/CPPFLAGS/CFLAGS usage. + Previous iOS/Xcode fixes for the ARM NEON optimizations moved the test + on __ARM_NEON__ from configure time to compile time. This breaks symbol + prefixing because the definition of the special png_init_filter_functions + call was hidden at configure time if the relevant compiler arguments are + passed in CFLAGS as opposed to CC. This change attempts to avoid all + the confusion that would result by declaring the init function even when + it is not used, so that it will always get prefixed. + +Version 1.6.3beta08 [June 18, 2013] + Revised libpng.3 so that "doclifter" can process it. + +Version 1.6.3beta09 [June 27, 2013] + Revised example.c to illustrate use of PNG_DEFAULT_sRGB and PNG_GAMMA_MAC_18 + as parameters for png_set_gamma(). These have been available since + libpng-1.5.4. + Renamed contrib/tools/png-fix-too-far-back.c to pngfix.c and revised it + to check all compressed chunks known to libpng. + +Version 1.6.3beta10 [July 5, 2013] + Updated documentation to show default behavior of benign errors correctly. + Only compile ARM code when PNG_READ_SUPPORTED is defined. + Fixed undefined behavior in contrib/tools/pngfix.c and added new strip + option. pngfix relied on undefined behavior and even a simple change from + gcc to g++ caused it to fail. The new strip option 'unsafe' has been + implemented and is the default if --max is given. Option names have + been clarified, with --strip=transform now stripping the bKGD chunk, + which was stripped previously with --strip=unused. + Added all documented chunk types to pngpriv.h + Unified pngfix.c source with libpng17. + +Version 1.6.3rc01 [July 11, 2013] + No changes. + +Version 1.6.3 [July 18, 2013] + Revised manual about changes in iTXt chunk handling made in libpng-1.6.0. + Added "/* SAFE */" comments in pngrutil.c and pngrtran.c where warnings + may be erroneously issued by code-checking applications. + +Version 1.6.4beta01 [August 21, 2013] + Added information about png_set_options() to the manual. + Delay calling png_init_filter_functions() until a row with nonzero filter + is found. + +Version 1.6.4beta02 [August 30, 2013] + Fixed inconsistent conditional compilation of png_chunk_unknown_handling() + prototype, definition, and usage. Made it depend on + PNG_HANDLE_AS_UNKNOWN_SUPPORTED everywhere. + +Version 1.6.4rc01 [September 5, 2013] + No changes. + +Version 1.6.4 [September 12, 2013] + No changes. + +Version 1.6.5 [September 14, 2013] + Removed two stray lines of code from arm/arm_init.c. + +Version 1.6.6 [September 16, 2013] + Removed two stray lines of code from arm/arm_init.c, again. + +Version 1.6.7beta01 [September 30, 2013] + Revised unknown chunk code to correct several bugs in the NO_SAVE_/NO_WRITE + combination + Allow HANDLE_AS_UNKNOWN to work when other options are configured off. Also + fixed the pngminim makefiles to work when $(MAKEFLAGS) contains stuff + which terminates the make options (as by default in recent versions of + Gentoo). + Avoid up-cast warnings in pngvalid.c. On ARM the alignment requirements of + png_modifier are greater than that of png_store and as a consequence + compilation of pngvalid.c results in a warning about increased alignment + requirements because of the bare cast to (png_modifier*). The code is safe, + because the pointer is known to point to a stack allocated png_modifier, + but this change avoids the warning. + Fixed default behavior of ARM_NEON_API. If the ARM NEON API option was + compiled without the CHECK option it defaulted to on, not off. + Check user callback behavior in pngunknown.c. Previous versions compiled + if SAVE_UNKNOWN was not available but did nothing since the callback + was never implemented. + Merged pngunknown.c with 1.7 version and back ported 1.7 improvements/fixes + +Version 1.6.7beta02 [October 12, 2013] + Made changes for compatibility with automake 1.14: + 1) Added the 'compile' program to the list of programs that must be cleaned + in autogen.sh + 2) Added 'subdir-objects' which causes .c files in sub-directories to be + compiled such that the corresponding .o files are also in the + sub-directory. This is because automake 1.14 warns that the + current behavior of compiling to the top level directory may be removed + in the future. + 3) Updated dependencies on pnglibconf.h to match the new .o locations and + added all the files in contrib/libtests and contrib/tools that depend + on pnglibconf.h + 4) Added 'BUILD_SOURCES = pnglibconf.h'; this is the automake recommended + way of handling the dependencies of sources that are machine generated; + unfortunately it only works if the user does 'make all' or 'make check', + so the dependencies (3) are still required. + Cleaned up (char*) casts of zlib messages. The latest version of the Intel C + compiler complains about casting a string literal as (char*), so copied the + treatment of z_const from the library code into pngfix.c + Simplified error message code in pngunknown. The simplification has the + useful side effect of avoiding a bogus warning generated by the latest + version of the Intel C compiler (it objects to + condition ? string-literal : string-literal). + Make autogen.sh work with automake 1.13 as well as 1.14. Do this by always + removing the 1.14 'compile' script but never checking for it. + +Version 1.6.7beta03 [October 19, 2013] + Added ARMv8 support (James Yu ). Added file + arm/filter_neon_intrinsics.c; enable with -mfpu=neon. + Revised pngvalid to generate size images with as many filters as it can + manage, limited by the number of rows. + Cleaned up ARM NEON compilation handling. The tests are now in pngpriv.h + and detect the broken GCC compilers. + +Version 1.6.7beta04 [October 26, 2013] + Allow clang derived from older GCC versions to use ARM intrinsics. This + causes all clang builds that use -mfpu=neon to use the intrinsics code, + not the assembler code. This has only been tested on iOS 7. It may be + necessary to exclude some earlier clang versions but this seems unlikely. + Changed NEON implementation selection mechanism. This allows assembler + or intrinsics to be turned on at compile time during the build by defining + PNG_ARM_NEON_IMPLEMENTATION to the correct value (2 or 1). This macro + is undefined by default and the build type is selected in pngpriv.h. + +Version 1.6.7rc01 [November 2, 2013] + No changes. + +Version 1.6.7rc02 [November 7, 2013] + Fixed #include in filter_neon_intrinsics.c and ctype macros. The ctype char + checking macros take an unsigned char argument, not a signed char. + +Version 1.6.7 [November 14, 2013] + No changes. + +Version 1.6.8beta01 [November 24, 2013] + Moved prototype for png_handle_unknown() in pngpriv.h outside of + the #ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED/#endif block. + Added "-Wall" to CFLAGS in contrib/pngminim/*/makefile + Conditionally compile some unused functions reported by -Wall in + pngminim. + Fixed 'minimal' builds. Various obviously useful minimal configurations + don't build because of missing contrib/libtests test programs and + overly complex dependencies in scripts/pnglibconf.dfa. This change + adds contrib/conftest/*.dfa files that can be used in automatic build + scripts to ensure that these configurations continue to build. + Enabled WRITE_INVERT and WRITE_PACK in contrib/pngminim/encoder. + Fixed pngvalid 'fail' function declaration on the Intel C Compiler. + This reverts to the previous 'static' implementation and works round + the 'unused static function' warning by using PNG_UNUSED(). + +Version 1.6.8beta02 [November 30, 2013] + Removed or marked PNG_UNUSED some harmless "dead assignments" reported + by clang scan-build. + Changed tabs to 3 spaces in png_debug macros and changed '"%s"m' + to '"%s" m' to improve portability among compilers. + Changed png_free_default() to free() in pngtest.c + +Version 1.6.8rc01 [December 12, 2013] + Tidied up pngfix inits and fixed pngtest no-write builds. + +Version 1.6.8rc02 [December 14, 2013] + Handle zero-length PLTE chunk or NULL palette with png_error() + instead of png_chunk_report(), which by default issues a warning + rather than an error, leading to later reading from a NULL pointer + (png_ptr->palette) in png_do_expand_palette(). This is CVE-2013-6954 + and VU#650142. Libpng-1.6.1 through 1.6.7 are vulnerable. + Libpng-1.6.0 and earlier do not have this bug. + +Version 1.6.8 [December 19, 2013] + No changes. + +Version 1.6.9beta01 [December 26, 2013] + Bookkeeping: Moved functions around (no changes). Moved transform + function definitions before the place where they are called so that + they can be made static. Move the intrapixel functions and the + grayscale palette builder out of the png?tran.c files. The latter + isn't a transform function and is no longer used internally, and the + former MNG specific functions are better placed in pngread/pngwrite.c + Made transform implementation functions static. This makes the internal + functions called by png_do_{read|write}_transformations static. On an + x86-64 DLL build (Gentoo Linux) this reduces the size of the text + segment of the DLL by 1208 bytes, about 0.6%. It also simplifies + maintenance by removing the declarations from pngpriv.h and allowing + easier changes to the internal interfaces. + Rebuilt configure scripts with automake-1.14.1 and autoconf-2.69 + in the tar distributions. + +Version 1.6.9beta02 [January 1, 2014] + Added checks for libpng 1.5 to pngvalid.c. This supports the use of + this version of pngvalid in libpng 1.5 + Merged with pngvalid.c from libpng-1.7 changes to create a single + pngvalid.c + Removed #error macro from contrib/tools/pngfix.c (Thomas Klausner). + Merged pngrio.c, pngtrans.c, pngwio.c, and pngerror.c with libpng-1.7.0 + Merged libpng-1.7.0 changes to make no-interlace configurations work + with test programs. + Revised pngvalid.c to support libpng 1.5, which does not support the + PNG_MAXIMUM_INFLATE_WINDOW option, so #define it out when appropriate in + pngvalid.c + Allow unversioned links created on install to be disabled in configure. + In configure builds 'make install' changes/adds links like png.h + and libpng.a to point to the newly installed, versioned, files (e.g. + libpng17/png.h and libpng17.a). Three new configure options and some + rearrangement of Makefile.am allow creation of these links to be disabled. + +Version 1.6.9beta03 [January 10, 2014] + Removed potentially misleading warning from png_check_IHDR(). + +Version 1.6.9beta04 [January 20, 2014] + Updated scripts/makefile.* to use CPPFLAGS (Cosmin). + Added clang attribute support (Cosmin). + +Version 1.6.9rc01 [January 28, 2014] + No changes. + +Version 1.6.9rc02 [January 30, 2014] + Quiet an uninitialized memory warning from VC2013 in png_get_png(). + +Version 1.6.9 [February 6, 2014] + +Version 1.6.10beta01 [February 9, 2014] + Backported changes from libpng-1.7.0beta30 and beta31: + Fixed a large number of instances where PNGCBAPI was omitted from + function definitions. + Added pngimage test program for png_read_png() and png_write_png() + with two new test scripts. + Removed dependence on !PNG_READ_EXPAND_SUPPORTED for calling + png_set_packing() in png_read_png(). + Fixed combination of ~alpha with shift. On read invert alpha, processing + occurred after shift processing, which causes the final values to be + outside the range that should be produced by the shift. Reversing the + order on read makes the two transforms work together correctly and mirrors + the order used on write. + Do not read invalid sBIT chunks. Previously libpng only checked sBIT + values on write, so a malicious PNG writer could therefore cause + the read code to return an invalid sBIT chunk, which might lead to + application errors or crashes. Such chunks are now skipped (with + chunk_benign_error). + Make png_read_png() and png_write_png() prototypes in png.h depend + upon PNG_READ_SUPPORTED and PNG_WRITE_SUPPORTED. + Support builds with unsupported PNG_TRANSFORM_* values. All of the + PNG_TRANSFORM_* values are always defined in png.h and, because they + are used for both read and write in some cases, it is not reliable + to #if out ones that are totally unsupported. This change adds error + detection in png_read_image() and png_write_image() to do a + png_app_error() if the app requests something that cannot be done + and it adds corresponding code to pngimage.c to handle such options + by not attempting to test them. + +Version 1.6.10beta02 [February 23, 2014] + Moved redefines of png_error(), png_warning(), png_chunk_error(), + and png_chunk_warning() from pngpriv.h to png.h to make them visible + to libpng-calling applications. + Moved OS dependent code from arm/arm_init.c, to allow the included + implementation of the ARM NEON discovery function to be set at + build-time and provide sample implementations from the current code in the + contrib/arm-neon subdirectory. The __linux__ code has also been changed to + compile and link on Android by using /proc/cpuinfo, and the old linux code + is in contrib/arm-neon/linux-auxv.c. The new code avoids POSIX and Linux + dependencies apart from opening /proc/cpuinfo and is C90 compliant. + Check for info_ptr == NULL early in png_read_end() so we don't need to + run all the png_handle_*() and depend on them to return if info_ptr == NULL. + This improves the performance of png_read_end(png_ptr, NULL) and makes + it more robust against future programming errors. + Check for __has_extension before using it in pngconf.h, to + support older Clang versions (Jeremy Sequoia). + Treat CRC error handling with png_set_crc_action(), instead of with + png_set_benign_errors(), which has been the case since libpng-1.6.0beta18. + Use a user warning handler in contrib/gregbook/readpng2.c instead of default, + so warnings will be put on stderr even if libpng has CONSOLE_IO disabled. + Added png_ptr->process_mode = PNG_READ_IDAT_MODE in png_push_read_chunk + after recognizing the IDAT chunk, which avoids an infinite loop while + reading a datastream whose first IDAT chunk is of zero-length. + This fixes CERT VU#684412 and CVE-2014-0333. + Don't recognize known sRGB profiles as sRGB if they have been hacked, + but don't reject them and don't issue a copyright violation warning. + +Version 1.6.10beta03 [February 25, 2014] + Moved some documentation from png.h to libpng.3 and libpng-manual.txt + Minor editing of contrib/arm-neon/README and contrib/examples/*.c + +Version 1.6.10rc01 [February 27, 2014] + Fixed typos in the manual and in scripts/pnglibconf.dfa (CFLAGS -> CPPFLAGS + and PNG_USR_CONFIG -> PNG_USER_CONFIG). + +Version 1.6.10rc02 [February 28, 2014] + Removed unreachable return statement after png_chunk_error() + in pngrutil.c + +Version 1.6.10rc03 [March 4, 2014] + Un-deprecated png_data_freer(). + +Version 1.6.10 [March 6, 2014] + No changes. + +Version 1.6.11beta01 [March 17, 2014] + Use "if (value != 0)" instead of "if (value)" consistently. + Changed ZlibSrcDir from 1.2.5 to 1.2.8 in projects/vstudio. + Moved configuration information from the manual to the INSTALL file. + +Version 1.6.11beta02 [April 6, 2014] + Removed #if/#else/#endif from inside two pow() calls in pngvalid.c because + they were handled improperly by Portland Group's PGI-14.1 - PGI-14.3 + when using its "__builtin_pow()" function. + Silence 'unused parameter' build warnings (Cosmin Truta). + $(CP) is now used alongside $(RM_F). Also, use 'copy' instead of 'cp' + where applicable, and applied other minor makefile changes (Cosmin). + Don't warn about invalid dimensions exceeding user limits (Cosmin). + Allow an easy replacement of the default pre-built configuration + header with a custom header, via the make PNGLIBCONF_H_PREBUILT + macro (Cosmin). + +Version 1.6.11beta03 [April 6, 2014] + Fixed a typo in pngrutil.c, introduced in libpng-1.5.6, that interferes + with "blocky" expansion of sub-8-bit interlaced PNG files (Eric Huss). + Optionally use __builtin_bswap16() in png_do_swap(). + +Version 1.6.11beta04 [April 19, 2014] + Made progressive reading of interlaced images consistent with the + behavior of the sequential reader and consistent with the manual, by + moving some code out of the PNG_READ_INTERLACING_SUPPORTED blocks. The + row_callback now receives the proper pass number and unexpanded rows, when + png_combine_row() isn't built or used, and png_set_interlace_handling() + is not called. + Allow PNG_sRGB_PROFILE_CHECKING = (-1) to mean no sRGB profile checking. + +Version 1.6.11beta05 [April 26, 2014] + Do not reject ICC V2 profiles that lack padding (Kai-Uwe Behrmann). + Relocated closing bracket of the sRGB profile test loop to avoid getting + "Not recognizing known sRGB profile that has been edited" warning for + ICC V2 profiles that lack the MD5 signature in the profile header. + +Version 1.6.11beta06 [May 19, 2014] + Added PNG_SKIP_sRGB_CHECK_PROFILE choice for png_set_option(). + +Version 1.6.11rc01 [May 27, 2014] + No changes. + +Version 1.6.11rc02 [June 3, 2014] + Test ZLIB_VERNUM instead of PNG_ZLIB_VERNUM in contrib/tools/pngfix.c + +Version 1.6.11 [June 5, 2014] + No changes. + +Version 1.6.12rc01 [June 6, 2014] + Relocated new code from 1.6.11beta06 in png.c to a point after the + declarations (Max Stepin). + +Version 1.6.12rc02 [June 7, 2014] + Changed file permissions of contrib/tools/intgamma.sh, + test-driver, and compile from 0644 to 0755 (Cosmin). + +Version 1.6.12rc03 [June 8, 2014] + Ensure "__has_attribute()" macro exists before trying to use it with + old clang compilers (MacPorts Ticket #43939). + +Version 1.6.12 [June 12, 2014] + No changes. + +Version 1.6.13beta01 [July 4, 2014] + Quieted -Wsign-compare and -Wclobber compiler warnings in + contrib/pngminus/*.c + Added "(void) png_ptr;" where needed in contrib/gregbook to quiet + compiler complaints about unused pointers. + Split a long output string in contrib/gregbook/rpng2-x.c. + Added "PNG_SET_OPTION" requirement for sRGB chunk support to pnglibconf.dfa, + Needed for write-only support (John Bowler). + Changed "if defined(__ARM_NEON__)" to + "if (defined(__ARM_NEON__) || defined(__ARM_NEON))" (James Wu). + Fixed clang no-warning builds: png_digit was defined but never used. + +Version 1.6.13beta02 [July 21, 2014] + Fixed an incorrect separator ("/" should be "\") in scripts/makefile.vcwin32 + (bug report from Wolfgang S. Kechel). Bug was introduced in libpng-1.6.11. + Also fixed makefile.bc32, makefile.bor, makefile.msc, makefile.intel, and + makefile.tc3 similarly. + +Version 1.6.13beta03 [August 3, 2014] + Removed scripts/makefile.elf.

Bug was introduced in libpng-1.6.0. + +Version 1.6.14beta05 [October 1, 2014] + Added "option READ_iCCP enables READ_COMPRESSED_TEXT" to pnglibconf.dfa + +Version 1.6.14beta06 [October 5, 2014] + Removed unused "text_len" parameter from private function png_write_zTXt(). + Conditionally compile some code in png_deflate_claim(), when + PNG_WARNINGS_SUPPORTED and PNG_ERROR_TEXT_SUPPORTED are disabled. + Replaced repeated code in pngpread.c with PNG_PUSH_SAVE_BUFFER_IF_FULL. + Added "chunk iTXt enables TEXT" and "chunk zTXt enables TEXT" + to pnglibconf.dfa. + Removed "option READ_COMPRESSED_TEXT enables READ_TEXT" from pnglibconf.dfa, + to make it possible to configure a libpng that supports iCCP but not TEXT. + +Version 1.6.14beta07 [October 7, 2014] + Removed "option WRITE_COMPRESSED_TEXT enables WRITE_TEXT" from pnglibconf.dfa + Only mark text chunks as written after successfully writing them. + +Version 1.6.14rc01 [October 15, 2014] + Fixed some typos in comments. + +Version 1.6.14rc02 [October 17, 2014] + Changed png_convert_to_rfc_1123() to png_convert_to_rfc_1123_buffer() + in the manual, to reflect the change made in libpng-1.6.0. + Updated README file to explain that direct access to the png_struct + and info_struct members has not been permitted since libpng-1.5.0. + +Version 1.6.14 [October 23, 2014] + No changes. + +Version 1.6.15beta01 [October 29, 2014] + Changed "if (!x)" to "if (x == 0)" and "if (x)" to "if (x != 0)" + Simplified png_free_data(). + Added missing "ptr = NULL" after some instances of png_free(). + +Version 1.6.15beta02 [November 1, 2014] + Changed remaining "if (!x)" to "if (x == 0)" and "if (x)" to "if (x != 0)" + +Version 1.6.15beta03 [November 3, 2014] + Added PNG_USE_ARM_NEON configuration flag (Marcin Juszkiewicz). + +Version 1.6.15beta04 [November 4, 2014] + Removed new PNG_USE_ARM_NEON configuration flag and made a one-line + revision to configure.ac to support ARM on aarch64 instead (John Bowler). + +Version 1.6.15beta05 [November 5, 2014] + Use png_get_libpng_ver(NULL) instead of PNG_LIBPNG_VER_STRING in + example.c, pngtest.c, and applications in the contrib directory. + Fixed an out-of-range read in png_user_version_check() (Bug report from + Qixue Xiao, CVE-2015-8540). + Simplified and future-proofed png_user_version_check(). + Fixed GCC unsigned int->float warnings. Various versions of GCC + seem to generate warnings when an unsigned value is implicitly + converted to double. This is probably a GCC bug but this change + avoids the issue by explicitly converting to (int) where safe. + Free all allocated memory in pngimage. The file buffer cache was left + allocated at the end of the program, harmless but it causes memory + leak reports from clang. + Fixed array size calculations to avoid warnings. At various points + in the code the number of elements in an array is calculated using + sizeof. This generates a compile time constant of type (size_t) which + is then typically assigned to an (unsigned int) or (int). Some versions + of GCC on 64-bit systems warn about the apparent narrowing, even though + the same compiler does apparently generate the correct, in-range, + numeric constant. This adds appropriate, safe, casts to make the + warnings go away. + +Version 1.6.15beta06 [November 6, 2014] + Reverted use png_get_libpng_ver(NULL) instead of PNG_LIBPNG_VER_STRING + in the manual, example.c, pngtest.c, and applications in the contrib + directory. It was incorrect advice. + +Version 1.6.15beta07 [November 7, 2014] + Removed #ifdef PNG_16BIT_SUPPORTED/#endif around png_product2(); it is + needed by png_reciprocal2(). + Added #ifdef PNG_16BIT_SUPPORTED/#endif around png_log16bit() and + png_do_swap(). + Changed all "#endif /* PNG_FEATURE_SUPPORTED */" to "#endif /* FEATURE */" + +Version 1.6.15beta08 [November 8, 2014] + More housecleaning in *.h + +Version 1.6.15rc01 [November 13, 2014] + +Version 1.6.15rc02 [November 14, 2014] + The macros passed in the command line to Borland make were ignored if + similarly-named macros were already defined in makefiles. This behavior + is different from POSIX make and other make programs. Surround the + macro definitions with ifndef guards (Cosmin). + +Version 1.6.15rc03 [November 16, 2014] + Added "-D_CRT_SECURE_NO_WARNINGS" to CFLAGS in scripts/makefile.vcwin32. + Removed the obsolete $ARCH variable from scripts/makefile.darwin. + +Version 1.6.15 [November 20, 2014] + No changes. + +Version 1.6.16beta01 [December 14, 2014] + Added ".align 2" to arm/filter_neon.S to support old GAS assemblers that + don't do alignment correctly. + Revised Makefile.am and scripts/symbols.dfn to work with MinGW/MSYS + (Bob Friesenhahn). + +Version 1.6.16beta02 [December 15, 2014] + Revised Makefile.am and scripts/*.dfn again to work with MinGW/MSYS; + renamed scripts/*.dfn to scripts/*.c (John Bowler). + +Version 1.6.16beta03 [December 21, 2014] + Quiet a "comparison always true" warning in pngstest.c (John Bowler). + +Version 1.6.16rc01 [December 21, 2014] + Restored a test on width that was removed from png.c at libpng-1.6.9 + (Bug report by Alex Eubanks, CVE-2015-0973). + +Version 1.6.16rc02 [December 21, 2014] + Undid the update to pngrutil.c in 1.6.16rc01. + +Version 1.6.16rc03 [December 21, 2014] + Fixed an overflow in png_combine_row() with very wide interlaced images + (Bug report and fix by John Bowler, CVE-2014-9495). + +Version 1.6.16 [December 22, 2014] + No changes. + +Version 1.6.17beta01 [January 29, 2015] + Removed duplicate PNG_SAFE_LIMITS_SUPPORTED handling from pngconf.h + Corrected the width limit calculation in png_check_IHDR(). + Removed user limits from pngfix. Also pass NULL pointers to + png_read_row to skip the unnecessary row de-interlace stuff. + Added testing of png_set_packing() to pngvalid.c + Regenerated configure scripts in the *.tar distributions with libtool-2.4.4 + Implement previously untested cases of libpng transforms in pngvalid.c + Fixed byte order in png_do_read_filler() with 16-bit input. Previously + the high and low bytes of the filler, from png_set_filler() or from + png_set_add_alpha(), were read in the wrong order. + Made the check for out-of-range values in png_set_tRNS() detect + values that are exactly 2^bit_depth, and work on 16-bit platforms. + Merged some parts of libpng-1.6.17beta01 and libpng-1.7.0beta47. + Added #ifndef __COVERITY__ where needed in png.c, pngrutil.c and + pngset.c to avoid warnings about dead code. + Added "& 0xff" to many instances of expressions that are typecast + to (png_byte), to avoid Coverity warnings. + +Version 1.6.17beta02 [February 7, 2015] + Work around one more Coverity-scan dead-code warning. + Do not build png_product2() when it is unused. + +Version 1.6.17beta03 [February 17, 2015] + Display user limits in the output from pngtest. + Eliminated the PNG_SAFE_LIMITS macro and restored the 1-million-column + and 1-million-row default limits in pnglibconf.dfa, that can be reset + by the user at build time or run time. This provides a more robust + defense against DOS and as-yet undiscovered overflows. + +Version 1.6.17beta04 [February 21, 2015] + Added PNG_WRITE_CUSTOMIZE_COMPRESSION_SUPPORTED macro, on by default. + Allow user to call png_get_IHDR() with NULL arguments (Reuben Hawkins). + Rebuilt configure scripts with automake-1.15 and libtool-2.4.6 + +Version 1.6.17beta05 [February 25, 2015] + Restored compiling of png_reciprocal2 with PNG_NO_16BIT. + +Version 1.6.17beta06 [February 27, 2015] + Moved png_set_filter() prototype into a PNG_WRITE_SUPPORTED block + of png.h. + Avoid runtime checks when converting integer to png_byte with + Visual Studio (Sergey Kosarevsky) + +Version 1.6.17rc01 [March 4, 2015] + No changes. + +Version 1.6.17rc02 [March 9, 2015] + Removed some comments that the configure script did not handle + properly from scripts/pnglibconf.dfa and pnglibconf.h.prebuilt. + Free the unknown_chunks structure even when it contains no data. + +Version 1.6.17rc03 [March 12, 2015] + Updated CMakeLists.txt to add OSX framework, change YES/NO to ON/OFF + for consistency, and remove some useless tests (Alexey Petruchik). + +Version 1.6.17rc04 [March 16, 2015] + Remove pnglibconf.h, pnglibconf.c, and pnglibconf.out instead of + pnglibconf.* in "make clean" (Cosmin). + Fix bug in calculation of maxbits, in png_write_sBIT, introduced + in libpng-1.6.17beta01 (John Bowler). + +Version 1.6.17rc05 [March 21, 2015] + Define PNG_FILTER_* and PNG_FILTER_VALUE_* in png.h even when WRITE + is not supported (John Bowler). This fixes an error introduced in + libpng-1.6.17beta06. + Reverted "& 0xff" additions of version 1.6.17beta01. Libpng passes + the Coverity scan without them. + +Version 1.6.17rc06 [March 23, 2015] + Remove pnglibconf.dfn and pnglibconf.pre with "make clean". + Reformatted some "&0xff" instances to "& 0xff". + Fixed simplified 8-bit-linear to sRGB alpha. The calculated alpha + value was wrong. It's not clear if this affected the final stored + value; in the obvious code path the upper and lower 8-bits of the + alpha value were identical and the alpha was truncated to 8-bits + rather than dividing by 257 (John Bowler). + +Version 1.6.17 [March 26, 2015] + No changes. + +Version 1.6.18beta01 [April 1, 2015] + Removed PNG_SET_CHUNK_[CACHE|MALLOC]_LIMIT_SUPPORTED macros. They + have been combined with PNG_SET_USER_LIMITS_SUPPORTED (resolves + bug report by Andrew Church). + Fixed rgb_to_gray checks and added tRNS checks to pngvalid.c. This + fixes some arithmetic errors that caused some tests to fail on + some 32-bit platforms (Bug reports by Peter Breitenlohner [i686] + and Petr Gajdos [i586]). + +Version 1.6.18beta02 [April 26, 2015] + Suppressed some warnings from the Borland C++ 5.5.1/5.82 compiler + (Bug report by Viktor Szakats). + +Version 1.6.18beta03 [May 6, 2015] + Replaced "unexpected" with an integer (0xabadca11) in pngset.c + where a long was expected, to avoid a compiler warning when PNG_DEBUG > 1. + Added contrib/examples/simpleover.c, to demonstrate how to handle + alpha compositing of multiple images, using the "simplified API" + and an example PNG generation tool, contrib/examples/genpng.c + (John Bowler). + +Version 1.6.18beta04 [May 20, 2015] + PNG_RELEASE_BUILD replaces tests where the code depended on the build base + type and can be defined on the command line, allowing testing in beta + builds (John Bowler). + Avoid Coverity issue 80858 (REVERSE NULL) in pngtest.c PNG_DEBUG builds. + Avoid a harmless potential integer overflow in png_XYZ_from_xy() (Bug + report from Christopher Ferris). + +Version 1.6.18beta05 [May 31, 2015] + Backport filter selection code from libpng-1.7.0beta51, to combine + sub_row, up_row, avg_row, and paeth_row into try_row and tst_row. + Changed png_voidcast(), etc., to voidcast(), etc., in contrib/tools/pngfix.c + to avoid confusion with the libpng private macros. + Fixed old cut&paste bug in the weighted filter selection code in + pngwutil.c, introduced in libpng-0.95, March 1997. + +Version 1.6.18beta06 [June 1, 2015] + Removed WRITE_WEIGHTED_FILTERED code, to save a few kbytes of the + compiled library size. It never worked properly and as far as we can + tell, no one uses it. The png_set_filter_heuristics() and + png_set_filter_heuristics_fixed() APIs are retained but deprecated + and do nothing. + +Version 1.6.18beta07 [June 6, 2015] + Removed non-working progressive reader 'skip' function. This + function has apparently never been used. It was implemented + to support back-door modification of png_struct in libpng-1.4.x + but (because it does nothing and cannot do anything) was apparently + never tested (John Bowler). + Fixed cexcept.h in which GCC 5 now reports that one of the auto + variables in the Try macro needs to be volatile to prevent value + being lost over the setjmp (John Bowler). + Fixed NO_WRITE_FILTER and -Wconversion build breaks (John Bowler). + Fix g++ build breaks (John Bowler). + Quieted some Coverity issues in pngfix.c, png-fix-itxt.c, pngvalid.c, + pngstest.c, and pngimage.c. Most seem harmless, but png-fix-itxt + would only work with iTXt chunks with length 255 or less. + Added #ifdef's to contrib/examples programs so people don't try + to compile them without the minimum required support enabled + (suggested by Flavio Medeiros). + +Version 1.6.18beta08 [June 30, 2015] + Eliminated the final two Coverity defects (insecure temporary file + handling in contrib/libtests/pngstest.c; possible overflow of + unsigned char in contrib/tools/png-fix-itxt.c). To use the "secure" + file handling, define PNG_USE_MKSTEMP, otherwise "tmpfile()" will + be used. + Removed some unused WEIGHTED_FILTER macros from png.h and pngstruct.h + +Version 1.6.18beta09 [July 5, 2015] + Removed some useless typecasts from contrib/tools/png-fix-itxt.c + Fixed a new signed-unsigned comparison in pngrtran.c (Max Stepin). + Replaced arbitrary use of 'extern' with #define PNG_LINKAGE_*. To + preserve API compatibility, the new defines all default to "extern" + (requested by Jan Nijtmans). + +Version 1.6.18rc01 [July 9, 2015] + Belatedly added Mans Rullgard and James Yu to the list of Contributing + Authors. + +Version 1.6.18rc02 [July 12, 2015] + Restored unused FILTER_HEURISTIC macros removed at libpng-1.6.18beta08 + to png.h to avoid compatibility warnings. + +Version 1.6.18rc03 [July 15, 2015] + Minor changes to the man page + +Version 1.6.18 [July 23, 2015] + No changes. + +Version 1.6.19beta01 [July 30, 2015] + Updated obsolete information about the simplified API macros in the + manual pages (Bug report by Arc Riley). + Avoid potentially dereferencing NULL info_ptr in png_info_init_3(). + Rearranged png.h to put the major sections in the same order as + in libpng17. + Eliminated unused PNG_COST_SHIFT, PNG_WEIGHT_SHIFT, PNG_COST_FACTOR, and + PNG_WEIGHT_FACTOR macros. + Suppressed some warnings from the Borland C++ 5.5.1/5.82 compiler + (Bug report by Viktor Szakats). Several warnings remain and are + unavoidable, where we test for overflow. + Fixed potential leak of png_pixels in contrib/pngminus/pnm2png.c + Fixed uninitialized variable in contrib/gregbook/rpng2-x.c + +Version 1.6.19beta02 [August 19, 2015] + Moved config.h.in~ from the "libpng_autotools_files" list to the + "libpng_autotools_extra" list in autogen.sh because it was causing a + false positive for missing files (bug report by Robert C. Seacord). + Removed unreachable "break" statements in png.c, pngread.c, and pngrtran.c + to suppress clang warnings (Bug report by Viktor Szakats). + Fixed some bad links in the man page. + Changed "n bit" to "n-bit" in comments. + Added signed/unsigned 16-bit safety net. This removes the dubious + 0x8000 flag definitions on 16-bit systems. They aren't supported + yet the defs *probably* work, however it seems much safer to do this + and be advised if anyone, contrary to advice, is building libpng 1.6 + on a 16-bit system. It also adds back various switch default clauses + for GCC; GCC errors out if they are not present (with an appropriately + high level of warnings). + Safely convert num_bytes to a png_byte in png_set_sig_bytes() (Robert + Seacord). + Fixed the recently reported 1's complement security issue by replacing + the value that is illegal in the PNG spec, in both signed and unsigned + values, with 0. Illegal unsigned values (anything greater than or equal + to 0x80000000) can still pass through, but since these are not illegal + in ANSI-C (unlike 0x80000000 in the signed case) the checking that + occurs later can catch them (John Bowler). + +Version 1.6.19beta03 [September 26, 2015] + Fixed png_save_int_32 when int is not 2's complement (John Bowler). + Updated libpng16 with all the recent test changes from libpng17, + including changes to pngvalid.c to ensure that the original, + distributed, version of contrib/visupng/cexcept.h can be used + (John Bowler). + pngvalid contains the correction to the use of SAVE/STORE_ + UNKNOWN_CHUNKS; a bug revealed by changes in libpng 1.7. More + tests contain the --strict option to detect warnings and the + pngvalid-standard test has been corrected so that it does not + turn on progressive-read. There is a separate test which does + that. (John Bowler) + Also made some signed/unsigned fixes. + Make pngstest error limits version specific. Splitting the machine + generated error structs out to a file allows the values to be updated + without changing pngstest.c itself. Since libpng 1.6 and 1.7 have + slightly different error limits this simplifies maintenance. The + makepngs.sh script has also been updated to more accurately reflect + current problems in libpng 1.7 (John Bowler). + Incorporated new test PNG files into make check. tests/pngstest-* + are changed so that the new test files are divided into 8 groups by + gamma and alpha channel. These tests have considerably better code + and pixel-value coverage than contrib/pngsuite; however,coverage is + still incomplete (John Bowler). + Removed the '--strict' in 1.6 because of the double-gamma-correction + warning, updated pngstest-errors.h for the errors detected with the + new contrib/testspngs PNG test files (John Bowler). + +Version 1.6.19beta04 [October 15, 2015] + Worked around rgb-to-gray issues in libpng 1.6. The previous + attempts to ignore the errors in the code aren't quite enough to + deal with the 'channel selection' encoding added to libpng 1.7; abort. + pngvalid.c is changed to drop this encoding in prior versions. + Fixed 'pow' macros in pngvalid.c. It is legal for 'pow' to be a + macro, therefore the argument list cannot contain preprocessing + directives. Make sure pow is a function where this happens. This is + a minimal safe fix, the issue only arises in non-performance-critical + code (bug report by Curtis Leach, fix by John Bowler). + Added sPLT support to pngtest.c + +Version 1.6.19rc01 [October 23, 2015] + No changes. + +Version 1.6.19rc02 [October 31, 2015] + Prevent setting or writing over-length PLTE chunk (Cosmin Truta). + Silently truncate over-length PLTE chunk while reading. + Libpng incorrectly calculated the output rowbytes when the application + decreased either the number of channels or the bit depth (or both) in + a user transform. This was safe; libpng overallocated buffer space + (potentially by quite a lot; up to 4 times the amount required) but, + from 1.5.4 on, resulted in a png_error (John Bowler). + +Version 1.6.19rc03 [November 3, 2015] + Fixed some inconsequential cut-and-paste typos in png_set_cHRM_XYZ_fixed(). + Clarified COPYRIGHT information to state explicitly that versions + are derived from previous versions. + Removed much of the long list of previous versions from png.h and + libpng.3. + +Version 1.6.19rc04 [November 5, 2015] + Fixed new bug with CRC error after reading an over-length palette + (bug report by Cosmin Truta) (CVE-2015-8126). + +Version 1.6.19 [November 12, 2015] + Cleaned up coding style in png_handle_PLTE(). + +Version 1.6.20beta01 [November 20, 2015] + Avoid potential pointer overflow/underflow in png_handle_sPLT() and + png_handle_pCAL() (Bug report by John Regehr). + +Version 1.6.20beta02 [November 23, 2015] + Fixed incorrect implementation of png_set_PLTE() that uses png_ptr + not info_ptr, that left png_set_PLTE() open to the CVE-2015-8126 + vulnerability. Fixes CVE-2015-8472. + +Version 1.6.20beta03 [November 24, 2015] + Backported tests from libpng-1.7.0beta69. + +Version 1.6.20rc01 [November 26, 2015] + Fixed an error in handling of bad zlib CMINFO field in pngfix, found by + American Fuzzy Lop, reported by Brian Carpenter. inflate() doesn't + immediately fault a bad CMINFO field; instead a 'too far back' error + happens later (at least some times). pngfix failed to limit CMINFO to + the allowed values but then assumed that window_bits was in range, + triggering an assert. The bug is mostly harmless; the PNG file cannot + be fixed. + +Version 1.6.20rc02 [November 29, 2015] + In libpng 1.6 zlib initialization was changed to use the window size + in the zlib stream, not a fixed value. This causes some invalid images, + where CINFO is too large, to display 'correctly' if the rest of the + data is valid. This provides a workaround for zlib versions where the + error arises (ones that support the API change to use the window size + in the stream). + +Version 1.6.20 [December 3, 2015] + No changes. + +Version 1.6.21beta01 [December 11, 2015] + Fixed syntax "$(command)" in tests/pngstest that some shells other than + bash could not parse (Bug report by Nelson Beebe). Use `command` instead. + +Version 1.6.21beta02 [December 14, 2015] + Moved png_check_keyword() from pngwutil.c to pngset.c + Removed LE/BE dependencies in pngvalid, to 'fix' the current problem + in the BigEndian tests by not testing it, making the BE code the same + as the LE version. + Fixes to pngvalid for various reduced build configurations (eliminate unused + statics) and a fix for the case in rgb_to_gray when the digitize option + reduces graylo to 0, producing a large error. + +Version 1.6.21beta03 [December 18, 2015] + Widened the 'limit' check on the internally calculated error limits in + the 'DIGITIZE' case (the code used prior to 1.7 for rgb_to_gray error + checks) and changed the check to only operate in non-release builds + (base build type not RC or RELEASE.) + Fixed undefined behavior in pngvalid.c, undefined because + (png_byte) << shift is undefined if it changes the signed bit + (because png_byte is promoted to int). The libpng exported functions + png_get_uint_32 and png_get_uint_16 handle this. (Bug reported by + David Drysdale as a result of reports from UBSAN in clang 3.8). + This changes pngvalid to use BE random numbers; this used to produce + errors but these should not be fixed as a result of the previous changes. + +Version 1.6.21rc01 [January 4, 2016] + In projects/vstudio, combined readme.txt and WARNING into README.txt + +Version 1.6.21rc02 [January 7, 2016] + Relocated assert() in contrib/tools/pngfix.c, bug found by American + Fuzzy Lop, reported by Brian Carpenter. + Marked 'limit' UNUSED in transform_range_check(). This only affects + release builds. + +Version 1.6.21 [January 15, 2016] + Worked around a false-positive Coverity issue in pngvalid.c. + +Version 1.6.22beta01 [January 23, 2016] + Changed PNG_USE_MKSTEMP to __COVERITY__ to select alternate + "tmpfile()" implementation in contrib/libtests/pngstest.c + Fixed NO_STDIO build of pngunknown.c to skip calling png_init_io() + if there is no stdio.h support. + Added a png_image_write_to_memory() API and a number of assist macros + to allow an application that uses the simplified API write to bypass + stdio and write directly to memory. + Added some warnings (png.h) and some check code to detect *possible* + overflow in the ROW_STRIDE and simplified image SIZE macros. This + disallows image width/height/format that *might* overflow. This is + a quiet API change that limits in-memory image size (uncompressed) to + less than 4GByte and image row size (stride) to less than 2GByte. + Revised workaround for false-positive Coverity issue in pngvalid.c. + +Version 1.6.22beta02 [February 8, 2016] + Only use exit(77) in configure builds. + Corrected error in PNG_IMAGE_PNG_SIZE_MAX. This new macro underreported + the palette size because it failed to take into account that the memory + palette has to be expanded to full RGB when it is written to PNG. + Updated CMakeLists.txt, added supporting scripts/gen*.cmake.in + and test.cmake.in (Roger Leigh). + Relaxed limit checks on gamma values in pngrtran.c. As suggested in + the comments gamma values outside the range currently permitted + by png_set_alpha_mode are useful for HDR data encoding. These values + are already permitted by png_set_gamma so it is reasonable caution to + extend the png_set_alpha_mode range as HDR imaging systems are starting + to emerge. + +Version 1.6.22beta03 [March 9, 2016] + Added a common-law trademark notice and export control information + to the LICENSE file, png.h, and the man page. + Restored "& 0xff" in png_save_uint_16() and png_save_uint_32() that + were accidentally removed from libpng-1.6.17. + Changed PNG_INFO_cHNK and PNG_FREE_cHNK from 0xnnnn to 0xnnnnU in png.h + (Robert C. Seacord). + Removed dubious "#if INT_MAX" test from png.h that was added to + libpng-1.6.19beta02 (John Bowler). + Add ${INCLUDES} in scripts/genout.cmake.in (Bug report by Nixon Kwok). + Updated LICENSE to say files in the contrib directory are not + necessarily under the libpng license, and that some makefiles have + other copyright owners. + Added INTEL-SSE2 support (Mike Klein and Matt Sarett, Google, Inc.). + Made contrib/libtests/timepng more robust. The code no longer gives + up/fails on invalid PNG data, it just skips it (with error messages). + The code no longer fails on PNG files with data beyond IEND. Options + exist to use png_read_png (reading the whole image, not by row) and, in + that case, to apply any of the supported transforms. This makes for + more realistic testing; the decoded data actually gets used in a + meaningful fashion (John Bowler). + Fixed some misleading indentation (Krishnaraj Bhat). + +Version 1.6.22beta04 [April 5, 2016] + Force GCC compilation to C89 if needed (Dagobert Michelsen). + SSE filter speed improvements for bpp=3: + memcpy-free implementations of load3() / store3(). + call load3() only when needed at the end of a scanline. + +Version 1.6.22beta05 [April 27, 2016] + Added PNG_FAST_FILTERS macro (defined as + PNG_FILTER_NONE|PNG_FILTER_SUB|PNG_FILTER_UP). + Various fixes for contrib/libtests/timepng.c + Moved INTEL-SSE code from pngpriv.h into contrib/intel/intel_sse.patch. + Fixed typo (missing underscore) in #define PNG_READ_16_TO_8_SUPPORTED + (Bug report by Y.Ohashik). + +Version 1.6.22beta06 [May 5, 2016] + Rebased contrib/intel_sse.patch. + Quieted two Coverity issues in contrib/libtests/timepng.c. + Fixed issues with scripts/genout.cmake.in (David Capello, Nixon Kwok): + Added support to use multiple directories in ZLIBINCDIR variable, + Fixed CMAKE_C_FLAGS with multiple values when genout is compiled on MSVC, + Fixed pnglibconf.c compilation on OS X including the sysroot path. + +Version 1.6.22rc01 [May 14, 2016] + No changes. + +Version 1.6.22rc02 [May 16, 2016] + Removed contrib/timepng from default build; it does not build on platforms + that don't supply clock_gettime(). + +Version 1.6.22rc03 [May 17, 2016] + Restored contrib/timepng to default build but check for the presence + of clock_gettime() in configure.ac and Makefile.am. + +Version 1.6.22 [May 26, 2016] + No changes. + +Version 1.6.23beta01 [May 29, 2016] + Stop a potential memory leak in png_set_tRNS() (Bug report by Ted Ying). + Fixed the progressive reader to handle empty first IDAT chunk properly + (patch by Timothy Nikkel). This bug was introduced in libpng-1.6.0 and + only affected the libpng16 branch. + Added tests in pngvalid.c to check zero-length IDAT chunks in various + positions. Fixed the sequential reader to handle these more robustly + (John Bowler). + +Version 1.6.23rc01 [June 2, 2016] + Corrected progressive read input buffer in pngvalid.c. The previous version + the code invariably passed just one byte at a time to libpng. The intent + was to pass a random number of bytes in the range 0..511. + Moved sse2 prototype from pngpriv.h to contrib/intel/intel_sse.patch. + Added missing ")" in pngerror.c (Matt Sarrett). + +Version 1.6.23rc02 [June 4, 2016] + Fixed undefined behavior in png_push_save_buffer(). Do not call + memcpy() with a null source, even if count is zero (Leon Scroggins III). + +Version 1.6.23 [June 9, 2016] + Fixed bad link to RFC2083 in png.5 (Nikola Forro). + +Version 1.6.24beta01 [June 11, 2016] + Avoid potential overflow of the PNG_IMAGE_SIZE macro. This macro + is not used within libpng, but is used in some of the examples. + +Version 1.6.24beta02 [June 23, 2016] + Correct filter heuristic overflow handling. This was broken when the + write filter code was moved out-of-line; if there is a single filter and + the heuristic sum overflows the calculation of the filtered line is not + completed. In versions prior to 1.6 the code was duplicated in-line + and the check not performed, so the filter operation completed; however, + in the multi-filter case where the sum is performed the 'none' filter would + be selected if all the sums overflowed, even if it wasn't in the filter + list. The fix to the first problem is simply to provide PNG_SIZE_MAX as + the current lmins sum value; this means the sum can never exceed it and + overflows silently. A reasonable compiler that does choose to inline + the code will simply eliminate the sum check. + The fix to the second problem is to use high precision arithmetic (this is + implemented in 1.7), however a simple safe fix here is to chose the lowest + numbered filter in the list from png_set_filter (this only works if the + first problem is also fixed) (John Bowler). + Use a more efficient absolute value calculation on SSE2 (Matthieu Darbois). + Fixed the case where PNG_IMAGE_BUFFER_SIZE can overflow in the application + as a result of the application using an increased 'row_stride'; previously + png_image_finish_read only checked for overflow on the base calculation of + components. (I.e. it checked for overflow of a 32-bit number on the total + number of pixel components in the output format, not the possibly padded row + length and not the number of bytes, which for linear formats is twice the + number of components.) + MSVC does not like '-(unsigned)', so replaced it with 0U-(unsigned) + MSVC does not like (uInt) = -(unsigned) (i.e. as an initializer), unless + the conversion is explicitly invoked by a cast. + Put the SKIP definition in the correct place. It needs to come after the + png.h include (see all the other .c files in contrib/libtests) because it + depends on PNG_LIBPNG_VER. + Removed the three compile warning options from the individual project + files into the zlib.props globals. It increases the warning level from 4 + to All and adds a list of the warnings that need to be turned off. This is + semi-documentary; the intent is to tell libpng users which warnings have + been examined and judged non-fixable at present. The warning about + structure padding is fixable, but it would be a significant change (moving + structure members around). + +Version 1.6.24beta03 [July 4, 2016] + Optimized absolute value calculation in filter selection, similar to + code in the PAETH decoder in pngrutil.c. Build with PNG_USE_ABS to + use this. + Added pngcp to the build together with a pngcp.dfa configuration test. + Added high resolution timing to pngcp. + Added "Common linking failures" section to INSTALL. + Relocated misplaced #endif in png.c sRGB profile checking. + Fixed two Coverity issues in pngcp.c. + +Version 1.6.24beta04 [July 8, 2016] + Avoid filter-selection heuristic sum calculations in cases where only one + filter is a candidate for selection. This trades off code size (added + private png_setup_*_row_only() functions) for speed. + +Version 1.6.24beta05 [July 13, 2016] + Fixed some indentation to comply with our coding style. + Added contrib/tools/reindent. + +Version 1.6.24beta06 [July 18, 2016] + Fixed more indentation to comply with our coding style. + Eliminated unnecessary tests of boolean png_isaligned() vs 0. + +Version 1.6.24rc01 [July 25, 2016] + No changes. + +Version 1.6.24rc02 [August 1, 2016] + Conditionally compile SSE2 headers in contrib/intel/intel_sse.patch + Conditionally compile png_decompress_chunk(). + +Version 1.6.24rc03 [August 2, 2016] + Conditionally compile ARM_NEON headers in pngpriv.h + Updated contrib/intel/intel_sse.patch + +Version 1.6.24[August 4, 2016] + No changes. + +Version 1.6.25beta01 [August 12, 2016] + Reject oversized iCCP profile immediately. + Cleaned up PNG_DEBUG compile of pngtest.c. + Conditionally compile png_inflate(). + +Version 1.6.25beta02 [August 18, 2016] + Don't install pngcp; it conflicts with pngcp in the pngtools package. + Minor editing of INSTALL, (whitespace, added copyright line) + +Version 1.6.25rc01 [August 24, 2016] + No changes. + +Version 1.6.25rc02 [August 29, 2016] + Added MIPS support (Mandar Sahastrabuddhe ). + Only the UP filter is currently implemented. + +Version 1.6.25rc03 [August 29, 2016] + Rebased contrib/intel/intel_sse.patch after the MIPS implementation. + +Version 1.6.25rc04 [August 30, 2016] + Added MIPS support for SUB, AVG, and PAETH filters (Mandar Sahastrabuddhe). + +Version 1.6.25rc05 [August 30, 2016] + Rebased contrib/intel/intel_sse.patch after the MIPS implementation update.. + +Version 1.6.25 [September 1, 2016] + No changes. + +Version 1.6.26beta01 [September 26, 2016] + Fixed handling zero length IDAT in pngfix (bug report by Agostino Sarubbo, + bugfix by John Bowler). + Do not issue a png_error() on read in png_set_pCAL() because png_handle_pCAL + has allocated memory that libpng needs to free. + Conditionally compile png_set_benign_errors() in pngread.c and pngtest.c + Issue a png_benign_error instead of a png_error on ADLER32 mismatch + while decoding compressed data chunks. + Changed PNG_ZLIB_VERNUM to ZLIB_VERNUM in pngpriv.h, pngstruct.h, and + pngrutil.c. + If CRC handling of critical chunks has been set to PNG_CRC_QUIET_USE, + ignore the ADLER32 checksum in the IDAT chunk as well as the chunk CRCs. + Issue png_benign_error() on ADLER32 checksum mismatch instead of png_error(). + Add tests/badcrc.png and tests/badadler.png to tests/pngtest. + Merged pngtest.c with libpng-1.7.0beta84/pngtest.c + +Version 1.6.26beta02 [October 1, 2016] + Updated the documentation about CRC and ADLER32 handling. + Quieted 117 warnings from clang-3.8 in pngtrans.c, pngread.c, + pngwrite.c, pngunknown.c, and pngvalid.c. + Quieted 58 (out of 144) -Wconversion compiler warnings by changing + flag definitions in pngpriv.h from 0xnnnn to 0xnnnnU and trivial changes + in png.c, pngread.c, and pngwutil.c. + +Version 1.6.26beta03 [October 2, 2016] + Removed contrib/libtests/*.orig and *.rej that slipped into the tarballs. + Quieted the 86 remaining -Wconversion compiler warnings by + revising the png_isaligned() macro and trivial changes in png.c, + pngerror.c, pngget.c, pngmem.c, pngset.c, pngrtran.c, pngrutil.c, + pngwtran.c, pngwrite.c, and pngwutil.c. + +Version 1.6.26beta04 [October 3, 2016] + Quieted (bogus?) clang warnings about "absolute value has no effect" + when PNG_USE_ABS is defined. + Fixed offsets in contrib/intel/intel_sse.patch + +Version 1.6.26beta05 [October 6, 2016] + Changed integer constant 4294967294 to unsigned 4294967294U in pngconf.h + to avoid a signed/unsigned compare in the preprocessor. + +Version 1.6.26beta06 [October 7, 2016] + Use zlib-1.2.8.1 inflateValidate() instead of inflateReset2() to + optionally avoid ADLER32 evaluation. + +Version 1.6.26rc01 [October 12, 2016] + No changes. + +Version 1.6.26 [October 20, 2016] + Cosmetic change, "ptr != 0" to "ptr != NULL" in png.c and pngrutil.c + Despammed email addresses (replaced "@" with " at "). + +Version 1.6.27beta01 [November 2, 2016] + Restrict the new ADLER32-skipping to IDAT chunks.

Simple installation + +On Unix/Linux and similar systems, you can simply type + + ./configure [--prefix=/path] + make check + make install + +and ignore the rest of this document. "/path" is the path to the directory +where you want to install the libpng "lib", "include", and "bin" +subdirectories. + +If you downloaded a GIT clone, you will need to run ./autogen.sh before +running ./configure, to create "configure" and "Makefile.in" which are +not included in the GIT repository. + +Note that "configure" is only included in the "*.tar" distributions and not +in the "*.zip" or "*.7z" distributions. If you downloaded one of those +distributions, see "Building with project files" or "Building with makefiles", +below. + +II. Rebuilding the configure scripts + +If configure does not work on your system, or if you have a need to +change configure.ac or Makefile.am, and you have a reasonably +up-to-date set of tools, running ./autogen.sh in a git clone before +running ./configure may fix the problem. To be really sure that you +aren't using any of the included pre-built scripts, especially if you +are building from a tar distribution instead of a git distribution, +do this: + + ./configure --enable-maintainer-mode + make maintainer-clean + ./autogen.sh --maintainer --clean + ./autogen.sh --maintainer + ./configure [--prefix=/path] [other options] + make + make install + make check + +III. Using scripts/makefile* + +Instead, you can use one of the custom-built makefiles in the +"scripts" directory + + cp scripts/pnglibconf.h.prebuilt pnglibconf.h + cp scripts/makefile.system makefile + make test + make install + +The files that are presently available in the scripts directory +are listed and described in scripts/README.txt. + +Or you can use one of the "projects" in the "projects" directory. + +Before installing libpng, you must first install zlib, if it +is not already on your system. zlib can usually be found +wherever you got libpng; otherwise go to https://zlib.net/. You can +place zlib in the same directory as libpng or in another directory. + +If your system already has a preinstalled zlib you will still need +to have access to the zlib.h and zconf.h include files that +correspond to the version of zlib that's installed. + +If you wish to test with a particular zlib that is not first in the +standard library search path, put ZLIBLIB, ZLIBINC, CPPFLAGS, LDFLAGS, +and LD_LIBRARY_PATH in your environment before running "make test" +or "make distcheck": + + ZLIBLIB=/path/to/lib export ZLIBLIB + ZLIBINC=/path/to/include export ZLIBINC + CPPFLAGS="-I$ZLIBINC" export CPPFLAGS + LDFLAGS="-L$ZLIBLIB" export LDFLAGS + LD_LIBRARY_PATH="$ZLIBLIB:$LD_LIBRARY_PATH" export LD_LIBRARY_PATH + +If you are using one of the makefile scripts, put ZLIBLIB and ZLIBINC +in your environment and type + + make ZLIBLIB=$ZLIBLIB ZLIBINC=$ZLIBINC test + +IV. Using cmake + +If you want to use "cmake" (see www.cmake.org), type + + cmake . -DCMAKE_INSTALL_PREFIX=/path + make + make install + +As when using the simple configure method described above, "/path" points to +the installation directory where you want to put the libpng "lib", "include", +and "bin" subdirectories. + +V. Directory structure + +You can rename the directories that you downloaded (they +might be called "libpng-x.y.z" or "libpngNN" and "zlib-1.2.8" +or "zlib128") so that you have directories called "zlib" and "libpng". + +Your directory structure should look like this: + + .. (the parent directory) + libpng (this directory) + INSTALL (this file) + README + *.h, *.c => libpng source files + CMakeLists.txt => "cmake" script + configuration files: + configure.ac, configure, Makefile.am, Makefile.in, + autogen.sh, config.guess, ltmain.sh, missing, libpng.pc.in, + libpng-config.in, aclocal.m4, config.h.in, config.sub, + depcomp, install-sh, mkinstalldirs, test-pngtest.sh + contrib + arm-neon, conftest, examples, gregbook, libtests, pngminim, + pngminus, pngsuite, tools, visupng + projects + cbuilder5, owatcom, visualc71, vstudio, xcode + scripts + makefile.* + *.def (module definition files) + etc. + pngtest.png + etc. + zlib + README, *.h, *.c contrib, etc. + +If the line endings in the files look funny, you may wish to get the other +distribution of libpng. It is available in both tar.gz (UNIX style line +endings) and zip (DOS style line endings) formats. + +VI. Building with project files + +If you are building libpng with MSVC, you can enter the +libpng projects\visualc71 or vstudio directory and follow the instructions +in README.txt. + +Otherwise enter the zlib directory and follow the instructions in zlib/README, +then come back here and run "configure" or choose the appropriate +makefile.sys in the scripts directory. + +VII. Building with makefiles + +Copy the file (or files) that you need from the +scripts directory into this directory, for example + +MSDOS example: + + copy scripts\makefile.msc makefile + copy scripts\pnglibconf.h.prebuilt pnglibconf.h + +UNIX example: + + cp scripts/makefile.std makefile + cp scripts/pnglibconf.h.prebuilt pnglibconf.h + +Read the makefile to see if you need to change any source or +target directories to match your preferences. + +Then read pnglibconf.dfa to see if you want to make any configuration +changes. + +Then just run "make" which will create the libpng library in +this directory and "make test" which will run a quick test that reads +the "pngtest.png" file and writes a "pngout.png" file that should be +identical to it. Look for "9782 zero samples" in the output of the +test. For more confidence, you can run another test by typing +"pngtest pngnow.png" and looking for "289 zero samples" in the output. +Also, you can run "pngtest -m contrib/pngsuite/*.png" and compare +your output with the result shown in contrib/pngsuite/README. + +Most of the makefiles will allow you to run "make install" to +put the library in its final resting place (if you want to +do that, run "make install" in the zlib directory first if necessary). +Some also allow you to run "make test-installed" after you have +run "make install". + +VIII. Configuring libpng for 16-bit platforms + +You will want to look into zconf.h to tell zlib (and thus libpng) that +it cannot allocate more than 64K at a time. Even if you can, the memory +won't be accessible. So limit zlib and libpng to 64K by defining MAXSEG_64K. + +IX. Configuring for DOS + +For DOS users who only have access to the lower 640K, you will +have to limit zlib's memory usage via a png_set_compression_mem_level() +call. See zlib.h or zconf.h in the zlib library for more information. + +X. Configuring for Medium Model + +Libpng's support for medium model has been tested on most of the popular +compilers. Make sure MAXSEG_64K gets defined, USE_FAR_KEYWORD gets +defined, and FAR gets defined to far in pngconf.h, and you should be +all set. Everything in the library (except for zlib's structure) is +expecting far data. You must use the typedefs with the p or pp on +the end for pointers (or at least look at them and be careful). Make +note that the rows of data are defined as png_bytepp, which is +an "unsigned char far * far *". + +XI. Prepending a prefix to exported symbols + +Starting with libpng-1.6.0, you can configure libpng (when using the +"configure" script) to prefix all exported symbols by means of the +configuration option "--with-libpng-prefix=FOO_", where FOO_ can be any +string beginning with a letter and containing only uppercase +and lowercase letters, digits, and the underscore (i.e., a C language +identifier). This creates a set of macros in pnglibconf.h, so this is +transparent to applications; their function calls get transformed by +the macros to use the modified names. + +XII. Configuring for compiler xxx: + +All includes for libpng are in pngconf.h. If you need to add, change +or delete an include, this is the place to do it. +The includes that are not needed outside libpng are placed in pngpriv.h, +which is only used by the routines inside libpng itself. +The files in libpng proper only include pngpriv.h and png.h, which +in turn includes pngconf.h and, as of libpng-1.5.0, pnglibconf.h. +As of libpng-1.5.0, pngpriv.h also includes three other private header +files, pngstruct.h, pnginfo.h, and pngdebug.h, which contain material +that previously appeared in the public headers. + +XIII. Removing unwanted object code + +There are a bunch of #define's in pngconf.h that control what parts of +libpng are compiled. All the defines end in _SUPPORTED. If you are +never going to use a capability, you can change the #define to #undef +before recompiling libpng and save yourself code and data space, or +you can turn off individual capabilities with defines that begin with +"PNG_NO_". + +In libpng-1.5.0 and later, the #define's are in pnglibconf.h instead. + +You can also turn all of the transforms and ancillary chunk capabilities +off en masse with compiler directives that define +PNG_NO_READ[or WRITE]_TRANSFORMS, or PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS, +or all four, along with directives to turn on any of the capabilities that +you do want. The PNG_NO_READ[or WRITE]_TRANSFORMS directives disable the +extra transformations but still leave the library fully capable of reading +and writing PNG files with all known public chunks. Use of the +PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS directive produces a library +that is incapable of reading or writing ancillary chunks. If you are +not using the progressive reading capability, you can turn that off +with PNG_NO_PROGRESSIVE_READ (don't confuse this with the INTERLACING +capability, which you'll still have). + +All the reading and writing specific code are in separate files, so the +linker should only grab the files it needs. However, if you want to +make sure, or if you are building a stand alone library, all the +reading files start with "pngr" and all the writing files start with "pngw". +The files that don't match either (like png.c, pngtrans.c, etc.) +are used for both reading and writing, and always need to be included. +The progressive reader is in pngpread.c + +If you are creating or distributing a dynamically linked library (a .so +or DLL file), you should not remove or disable any parts of the library, +as this will cause applications linked with different versions of the +library to fail if they call functions not available in your library. +The size of the library itself should not be an issue, because only +those sections that are actually used will be loaded into memory. + +XIV. Enabling or disabling hardware optimizations + +Certain hardware capabilities, such as the Intel SSE instructions, +are normally detected at run time. Enable them with configure options +such as one of + + --enable-arm-neon=yes + --enable-mips-msa=yes + --enable-intel-sse=yes + --enable-powerpc-vsx=yes + +or enable them all at once with + + --enable-hardware-optimizations=yes + +or, if you are not using "configure", you can use one +or more of + + CPPFLAGS += "-DPNG_ARM_NEON" + CPPFLAGS += "-DPNG_MIPS_MSA" + CPPFLAGS += "-DPNG_INTEL_SSE" + CPPFLAGS += "-DPNG_POWERPC_VSX" + +See for example scripts/makefile.linux-opt + +If you wish to avoid using them, +you can disable them via the configure option + + --disable-hardware-optimizations + +to disable them all, or + + --enable-intel-sse=no + +to disable a particular one, +or via compiler-command options such as + + CPPFLAGS += "-DPNG_ARM_NEON_OPT=0, -DPNG_MIPS_MSA_OPT=0, + -DPNG_INTEL_SSE_OPT=0, -DPNG_POWERPC_VSX_OPT=0" + +If you are using cmake, hardware optimizations are "on" +by default. To disable them, use + + cmake . -DPNG_ARM_NEON=no -DPNG_INTEL_SSE=no \ + -DPNG_MIPS_MSA=no -DPNG_POWERPC_VSX=no + +or disable them all at once with + + cmake . -DPNG_HARDWARE_OPTIMIZATIONS=no + +XV. Changes to the build and configuration of libpng in libpng-1.5.x + +Details of internal changes to the library code can be found in the CHANGES +file and in the GIT repository logs. These will be of no concern to the vast +majority of library users or builders; however, the few who configure libpng +to a non-default feature set may need to change how this is done. + +There should be no need for library builders to alter build scripts if +these use the distributed build support - configure or the makefiles - +however, users of the makefiles may care to update their build scripts +to build pnglibconf.h where the corresponding makefile does not do so. + +Building libpng with a non-default configuration has changed completely. +The old method using pngusr.h should still work correctly even though the +way pngusr.h is used in the build has been changed; however, library +builders will probably want to examine the changes to take advantage of +new capabilities and to simplify their build system. + +A. Specific changes to library configuration capabilities + +The exact mechanism used to control attributes of API functions has +changed. A single set of operating system independent macro definitions +is used and operating system specific directives are defined in +pnglibconf.h + +As part of this the mechanism used to choose procedure call standards on +those systems that allow a choice has been changed. At present this only +affects certain Microsoft (DOS, Windows) and IBM (OS/2) operating systems +running on Intel processors. As before, PNGAPI is defined where required +to control the exported API functions; however, two new macros, PNGCBAPI +and PNGCAPI, are used instead for callback functions (PNGCBAPI) and +(PNGCAPI) for functions that must match a C library prototype (currently +only png_longjmp_ptr, which must match the C longjmp function.) The new +approach is documented in pngconf.h + +Despite these changes, libpng 1.5.0 only supports the native C function +calling standard on those platforms tested so far ("__cdecl" on Microsoft +Windows). This is because the support requirements for alternative +calling conventions seem to no longer exist. Developers who find it +necessary to set PNG_API_RULE to 1 should advise the mailing list +(png-mng-implement) of this and library builders who use Openwatcom and +therefore set PNG_API_RULE to 2 should also contact the mailing list. + +B. Changes to the configuration mechanism + +Prior to libpng-1.5.0 library builders who needed to configure libpng +had either to modify the exported pngconf.h header file to add system +specific configuration or had to write feature selection macros into +pngusr.h and cause this to be included into pngconf.h by defining +PNG_USER_CONFIG. The latter mechanism had the disadvantage that an +application built without PNG_USER_CONFIG defined would see the +unmodified, default, libpng API and thus would probably fail to link. + +These mechanisms still work in the configure build and in any makefile +build that builds pnglibconf.h, although the feature selection macros +have changed somewhat as described above. In 1.5.0, however, pngusr.h is +processed only once, at the time the exported header file pnglibconf.h is +built. pngconf.h no longer includes pngusr.h; therefore, pngusr.h is ignored +after the build of pnglibconf.h and it is never included in an application +build. + +The formerly used alternative of adding a list of feature macros to the +CPPFLAGS setting in the build also still works; however, the macros will be +copied to pnglibconf.h and this may produce macro redefinition warnings +when the individual C files are compiled. + +All configuration now only works if pnglibconf.h is built from +scripts/pnglibconf.dfa. This requires the program awk. Brian Kernighan +(the original author of awk) maintains C source code of that awk and this +and all known later implementations (often called by subtly different +names - nawk and gawk for example) are adequate to build pnglibconf.h. +The Sun Microsystems (now Oracle) program 'awk' is an earlier version +and does not work; this may also apply to other systems that have a +functioning awk called 'nawk'. + +Configuration options are now documented in scripts/pnglibconf.dfa. This +file also includes dependency information that ensures a configuration is +consistent; that is, if a feature is switched off, dependent features are +also switched off. As a recommended alternative to using feature macros in +pngusr.h a system builder may also define equivalent options in pngusr.dfa +(or, indeed, any file) and add that to the configuration by setting +DFA_XTRA to the file name. The makefiles in contrib/pngminim illustrate +how to do this, and also illustrate a case where pngusr.h is still required. + +After you have built libpng, the definitions that were recorded in +pnglibconf.h are available to your application (pnglibconf.h is included +in png.h and gets installed alongside png.h and pngconf.h in your +$PREFIX/include directory). Do not edit pnglibconf.h after you have built +libpng, because than the settings would not accurately reflect the settings +that were used to build libpng. + +XVI. Setjmp/longjmp issues + +Libpng uses setjmp()/longjmp() for error handling. Unfortunately setjmp() +is known to be not thread-safe on some platforms and we don't know of +any platform where it is guaranteed to be thread-safe. Therefore, if +your application is going to be using multiple threads, you should +configure libpng with PNG_NO_SETJMP in your pngusr.dfa file, with +-DPNG_NO_SETJMP on your compile line, or with + + #undef PNG_SETJMP_SUPPORTED + +in your pnglibconf.h or pngusr.h. + +Starting with libpng-1.6.0, the library included a "simplified API". +This requires setjmp/longjmp, so you must either build the library +with PNG_SETJMP_SUPPORTED defined, or with PNG_SIMPLIFIED_READ_SUPPORTED +and PNG_SIMPLIFIED_WRITE_SUPPORTED undefined. + +XVII. Common linking failures + +If your application fails to find libpng or zlib entries while linking: + + Be sure "-lz" appears after "-lpng" on your linking command. + + Be sure you have built libpng, zlib, and your application for the + same platform (e.g., 32-bit or 64-bit). + + If you are using the vstudio project, observe the WARNING in + project/vstudio/README.txt. + +XVIII.

Get libpng-*.tar.gz or +libpng-*.tar.xz or if you want UNIX-style line endings in the text +files, or lpng*.7z or lpng*.zip if you want DOS-style line endings. + +Version 0.89 was the first official release of libpng. Don't let the +fact that it's the first release fool you. The libpng library has been +in extensive use and testing since mid-1995. By late 1997 it had +finally gotten to the stage where there hadn't been significant +changes to the API in some time, and people have a bad feeling about +libraries with versions < 1.0. Version 1.0.0 was released in +March 1998. + +**** +Note that some of the changes to the png_info structure render this +version of the library binary incompatible with libpng-0.89 or +earlier versions if you are using a shared library. The type of the +"filler" parameter for png_set_filler() has changed from png_byte to +png_uint_32, which will affect shared-library applications that use +this function. + +To avoid problems with changes to the internals of the png info_struct, +new APIs have been made available in 0.95 to avoid direct application +access to info_ptr. These functions are the png_set_ and +png_get_ functions. These functions should be used when +accessing/storing the info_struct data, rather than manipulating it +directly, to avoid such problems in the future. + +It is important to note that the APIs did not make current programs +that access the info struct directly incompatible with the new +library, through libpng-1.2.x. In libpng-1.4.x, which was meant to +be a transitional release, members of the png_struct and the +info_struct can still be accessed, but the compiler will issue a +warning about deprecated usage. Since libpng-1.5.0, direct access +to these structs is not allowed, and the definitions of the structs +reside in private pngstruct.h and pnginfo.h header files that are not +accessible to applications. It is strongly suggested that new +programs use the new APIs (as shown in example.c and pngtest.c), and +older programs be converted to the new format, to facilitate upgrades +in the future. +**** + +Additions since 0.90 include the ability to compile libpng as a +Windows DLL, and new APIs for accessing data in the info struct. +Experimental functions include the ability to set weighting and cost +factors for row filter selection, direct reads of integers from buffers +on big-endian processors that support misaligned data access, faster +methods of doing alpha composition, and more accurate 16->8 bit color +conversion. + +The additions since 0.89 include the ability to read from a PNG stream +which has had some (or all) of the signature bytes read by the calling +application. This also allows the reading of embedded PNG streams that +do not have the PNG file signature. As well, it is now possible to set +the library action on the detection of chunk CRC errors. It is possible +to set different actions based on whether the CRC error occurred in a +critical or an ancillary chunk. + +For a detailed description on using libpng, read libpng-manual.txt. +For examples of libpng in a program, see example.c and pngtest.c. For +usage information and restrictions (what little they are) on libpng, +see png.h. For a description on using zlib (the compression library +used by libpng) and zlib's restrictions, see zlib.h + +I have included a general makefile, as well as several machine and +compiler specific ones, but you may have to modify one for your own +needs. + +You should use zlib 1.0.4 or later to run this, but it MAY work with +versions as old as zlib 0.95. Even so, there are bugs in older zlib +versions which can cause the output of invalid compression streams for +some images. + +You should also note that zlib is a compression library that is useful +for more things than just PNG files. You can use zlib as a drop-in +replacement for fread() and fwrite(), if you are so inclined. + +zlib should be available at the same place that libpng is, or at +https://zlib.net. + +You may also want a copy of the PNG specification.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs.

As a result, + you need to download and build both zlib (on which libpng depends) and + libpng. A common build setup is to place the zlib, libpng and pngbook + subdirectory trees ("folders") in the same parent directory. Then the + libpng build can refer to files in ../zlib (or ..\zlib or [-.zlib]), + and similarly for the pngbook build. + + Note that all three packages are designed to be built from a command + line by default; those who wish to use a graphical or other integrated + development environments are on their own. + + + - Unix: + + Unpack the latest pngbook sources (which should correspond to this + README file) into a directory and change into that directory. + + Copy Makefile.unx to Makefile and edit the PNG* and Z* variables + appropriately (possibly also the X* variables if necessary). + + make + + There is no "install" target, so copy the three executables somewhere + in your path or run them from the current directory. All three will + print a basic usage screen when run without any command-line arguments; + see the book for more details. + + + - Windows: + + Unpack the latest pngbook sources (which should correspond to this + README file) into a folder, open a "DOS shell" or "command prompt" + or equivalent command-line window, and cd into the folder where you + unpacked the source code. + + For MSVC, set up the necessary environment variables by invoking + + %devstudio%\vc\bin\vcvars32.bat + + where where %devstudio% is the installation directory for MSVC / + DevStudio. If you get "environment out of space" errors under 95/98, + create a desktop shortcut with "c:\windows\command.com /e:4096" as + the program command line and set the working directory to the pngbook + directory. Then double-click to open the new DOS-prompt window with + a bigger environment and retry the commands above. + + Copy Makefile.w32 to Makefile and edit the PNGPATH and ZPATH variables + appropriately (possibly also the "INC" and "LIB" variables if needed). + Note that the names of the dynamic and static libpng and zlib libraries + used in the makefile may change in later releases of the libraries. + Also note that, as of libpng version 1.0.5, MSVC DLL builds do not work. + This makefile therefore builds statically linked executables, but if + the DLL problems ever get fixed, uncommenting the appropriate PNGLIB + and ZLIB lines will build dynamically linked executables instead. + + Do the build by typing + + nmake + + The result should be three executables: rpng-win.exe, rpng2-win.exe, + and wpng.exe. Copy them somewhere in your PATH or run them from the + current folder. Like the Unix versions, the two windowed programs + (rpng and rpng2) now display a usage screen in a console window when + invoked without command-line arguments; this is new behavior as of + the June 2001 release. Note that the programs use the Unix-style "-" + character to specify options, instead of the more common DOS/Windows + "/" character. (For example: "rpng2-win -bgpat 4 foo.png", not + "rpng2-win /bgpat 4 foo.png") + + + - OpenVMS: + + Unpack the pngbook sources into a subdirectory and change into that + subdirectory. + + Edit makevms.com appropriately, specifically the zpath and pngpath + variables. + + @makevms + + To run the programs, they probably first need to be set up as "foreign + symbols," with "disk" and "dir" set appropriately: + + $ rpng == "$disk:[dir]rpng-x.exe" + $ rpng2 == "$disk:[dir]rpng2-x.exe" + $ wpng == "$disk:[dir]wpng.exe" + + All three will print a basic usage screen when run without any command- + line arguments; see the book for more details. Note that the options + style is Unix-like, i.e., preceded by "-" rather than "/". + + +RUNNING THE PROGRAMS: (VERY) BRIEF INTRO + + rpng is a simple PNG viewer that can display transparent PNGs with a + specified background color; for example, + + rpng -bgcolor \#ff0000 toucan.png + + would display the image with a red background. rpng2 is a progressive + viewer that simulates a web browser in some respects; it can display + images against either a background color or a dynamically generated + background image. For example: + + rpng2 -bgpat 16 toucan.png + + wpng is a purely command-line image converter from binary PBMPLUS/NetPBM + format (.pgm or .ppm) to PNG; for example, + + wpng -time < toucan-notrans.ppm > toucan-notrans.png + + would convert the specified PPM file (using redirection) to PNG, auto- + matically setting the PNG modification-time chunk. + + All options can be abbreviated to the shortest unique value; for example, + "-bgc" for -bgcolor (versus "-bgp" for -bgpat), or "-g" for -gamma. diff --git a/project/jni/sdl2_image/external/libpng-1.6.37/contrib/gregbook/makevms.com b/project/jni/sdl2_image/external/libpng-1.6.37/contrib/gregbook/makevms.com new file mode 100644 index 000000000..f32bcaba7 --- /dev/null +++ b/project/jni/sdl2_image/external/libpng-1.6.37/contrib/gregbook/makevms.com @@ -0,0 +1,132 @@ +$!------------------------------------------------------------------------------ +$! make "PNG: The Definitive Guide" demo programs (for X) under OpenVMS +$! +$!
