You will definitely need zlib 1.0.4 or later if you are -taking advantage of the MS-DOS "far" structure allocation for the small -and medium memory models. 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 zlib.net. - -You may also want a copy of the PNG specification. It is available -as an RFC, a W3C Recommendation, and an ISO/IEC Standard. You can find -these at http://www.libpng.org/pub/png/pngdocs.html . - -This code is currently being archived at libpng.sourceforge.io in the -[DOWNLOAD] area, and at http://libpng.download/src . If you -can't find it in any of those places, e-mail me, and I'll help you find it. - -I am not a lawyer, but I believe that the Export Control Classification -Number (ECCN) for libpng is EAR99, which means not subject to export -controls or International Traffic in Arms Regulations (ITAR) because it -is open source, publicly available software, that does not contain any -encryption software. See the EAR, paragraphs 734.3(b)(3) and 734.7(b). - -If you have any code changes, requests, problems, etc., please e-mail -them to me. Also, I'd appreciate any make files or project files, -and any modifications you needed to make to get libpng to compile, -along with a #define variable to tell what compiler/system you are on. -If you needed to add transformations to libpng, or wish libpng would -provide the image in a different way, drop me a note (and code, if -possible), so I can consider supporting the transformation. -Finally, if you get any warning messages when compiling libpng -(note: not zlib), and they are easy to fix, I'd appreciate the -fix. Please mention "libpng" somewhere in the subject line. Thanks. - -This release was created and will be supported by myself (of course -based in a large way on Guy's and Andreas' earlier work), and the PNG -development group. - -Send comments/corrections/commendations to png-mng-implement at -lists.sourceforge.net (subscription required; visit -https://lists.sourceforge.net/lists/listinfo/png-mng-implement -to subscribe) or to glennrp at users.sourceforge.net - -You can't reach Guy, the original libpng author, at the addresses -given in previous versions of this document. He and Andreas will -read mail addressed to the png-implement list, however. - -Please do not send general questions about PNG. Send them to -png-mng-misc at lists.sf.net (subscription required; visit -https://lists.sourceforge.net/lists/listinfo/png-mng-misc to -subscribe). If you have a question about something -in the PNG specification that is related to using libpng, send it -to me. Send me any questions that start with "I was using libpng, -and ...". If in doubt, send questions to me. I'll bounce them -to others, if necessary. - -Please do not send suggestions on how to change PNG. We have -been discussing PNG for twenty years now, and it is official and -finished. If you have suggestions for libpng, however, I'll -gladly listen. Even if your suggestion is not used immediately, -it may be used later. - -Files in this distribution: - - ANNOUNCE => Announcement of this version, with recent changes - CHANGES => Description of changes between libpng versions - KNOWNBUG => List of known bugs and deficiencies - LICENSE => License to use and redistribute libpng - README => This file - TODO => Things not implemented in the current library - Y2KINFO => Statement of Y2K compliance - example.c => Example code for using libpng functions - libpng.3 => manual page for libpng (includes libpng-manual.txt) - libpng-manual.txt => Description of libpng and its functions - libpngpf.3 => manual page for libpng's private functions - png.5 => manual page for the PNG format - png.c => Basic interface functions common to library - png.h => Library function and interface declarations (public) - pngpriv.h => Library function and interface declarations (private) - pngconf.h => System specific library configuration (public) - pngstruct.h => png_struct declaration (private) - pnginfo.h => png_info struct declaration (private) - pngdebug.h => debugging macros (private) - pngerror.c => Error/warning message I/O functions - pngget.c => Functions for retrieving info from struct - pngmem.c => Memory handling functions - pngbar.png => PNG logo, 88x31 - pngnow.png => PNG logo, 98x31 - pngpread.c => Progressive reading functions - pngread.c => Read data/helper high-level functions - pngrio.c => Lowest-level data read I/O functions - pngrtran.c => Read data transformation functions - pngrutil.c => Read data utility functions - pngset.c => Functions for storing data into the info_struct - pngtest.c => Library test program - pngtest.png => Library test sample image - pngtrans.c => Common data transformation functions - pngwio.c => Lowest-level write I/O functions - pngwrite.c => High-level write functions - pngwtran.c => Write data transformations - pngwutil.c => Write utility functions - arm => Contains optimized code for the ARM platform - powerpc => Contains optimized code for the PowerPC platform - contrib => Contributions - arm-neon => Optimized code for ARM-NEON platform - powerpc-vsx => Optimized code for POWERPC-VSX platform - examples => Example programs - gregbook => source code for PNG reading and writing, from - Greg Roelofs' "PNG: The Definitive Guide", - O'Reilly, 1999 - libtests => Test programs - mips-msa => Optimized code for MIPS-MSA platform - pngminim => Minimal decoder, encoder, and progressive decoder - programs demonstrating use of pngusr.dfa - pngminus => Simple pnm2png and png2pnm programs - pngsuite => Test images - testpngs - tools => Various tools - visupng => Contains a MSVC workspace for VisualPng - intel => Optimized code for INTEL-SSE2 platform - mips => Optimized code for MIPS platform - projects => Contains project files and workspaces for - building a DLL - owatcom => Contains a WATCOM project for building libpng - visualc71 => Contains a Microsoft Visual C++ (MSVC) - workspace for building libpng and zlib - vstudio => Contains a Microsoft Visual C++ (MSVC) - workspace for building libpng and zlib - scripts => Directory containing scripts for building libpng: - (see scripts/README.txt for the list of scripts) - -Good luck, and happy coding. - --Glenn Randers-Pehrson (current maintainer, since 1998) - Internet: glennrp at users.sourceforge.net - --Andreas Eric Dilger (former maintainer, 1996-1997) - Internet: adilger at enel.ucalgary.ca - Web: http://www-mddsp.enel.ucalgary.ca/People/adilger/ - --Guy Eric Schalnat (original author and former maintainer, 1995-1996) - (formerly of Group 42, Inc) - Internet: gschal at infinet.com +The 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 included 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-to-8 bit color +conversion.

The - * png_convert_from_time_t() function calls gmtime() to convert from system - * clock time, which returns (year - 1900), which we properly convert to - * the full 4-digit year. There is a possibility that libpng applications - * are not passing 4-digit years into the png_convert_to_rfc_1123_buffer() - * function, or that they are incorrectly passing only a 2-digit year - * instead of "year - 1900" into the png_convert_from_struct_tm() function, - * but this is not under our control.
