Added check for zero-area RGB cHRM triange in png_check_cHRM_fixed(). - In png_check_cHRM_fixed(), ensure white_y is > 0, and removed redundant - check for all-zero coordinates that is detected by the triangle check. - Revised png_warning() to write its message on standard output by default - when warning_fn is NULL. - Corrected off-by-one error in bKGD validity check in png_write_bKGD() - and in png_handle_bKGD(). -

cleaned up documentation - added callbacks for read/write and warning/error functions - -version 0.89 [July, 1996] - added new initialization API to make libpng work better with shared libs - we now have png_create_read_struct(), png_create_write_struct(), - png_create_info_struct(), png_destroy_read_struct(), and - png_destroy_write_struct() instead of the separate calls to - malloc and png_read_init(), png_info_init(), and png_write_init() - changed warning/error callback functions to fix bug - this means you - should use the new initialization API if you were using the old - png_set_message_fn() calls, and that the old API no longer exists - so that people are aware that they need to change their code - changed filter selection API to allow selection of multiple filters - since it didn't work in previous versions of libpng anyways - optimized filter selection code - fixed png_set_background() to allow using an arbitrary RGB color for - paletted images - fixed gamma and background correction for paletted images, so - png_correct_palette is not needed unless you are correcting an - external palette (you will need to #define PNG_CORRECT_PALETTE_SUPPORTED - in pngconf.h) - if nobody uses this, it may disappear in the future. - fixed bug with Borland 64K memory allocation (Alexander Lehmann) - fixed bug in interlace handling (Smarasderagd, I think) - added more error checking for writing and image to reduce invalid files - separated read and write functions so that they won't both be linked - into a binary when only reading or writing functionality is used - new pngtest image also has interlacing and zTXt - updated documentation to reflect new API - -version 0.90 [January, 1997] - made CRC errors/warnings on critical and ancillary chunks configurable - libpng will use the zlib CRC routines by (compile-time) default - changed DOS small/medium model memory support - needs zlib 1.04 (Tim Wegner) - added external C++ wrapper statements to png.h (Gilles Dauphin) - allow PNG file to be read when some or all of file signature has already - been read from the beginning of the stream. ****This affects the size - of info_struct and invalidates all programs that use a shared libpng**** - fixed png_filler() declarations - fixed? background color conversions - fixed order of error function pointers to match documentation - current chunk name is now available in png_struct to reduce the number - of nearly identical error messages (will simplify multi-lingual - support when available) - try to get ready for unknown-chunk callback functions: - - previously read critical chunks are flagged, so the chunk handling - routines can determine if the chunk is in the right place - - all chunk handling routines have the same prototypes, so we will - be able to handle all chunks via a callback mechanism - try to fix Linux "setjmp" buffer size problems - removed png_large_malloc, png_large_free, and png_realloc functions. - -version 0.95 [March, 1997] -

to png_uint_32 - added test for MACOS to ensure that both math.h and fp.h are not #included - added macros for libpng to be compiled as a Windows DLL (Andreas Kupries) - added "packswap" transformation, which changes the endianness of - packed-pixel bytes (Kevin Bracey) - added "strip_alpha" transformation, which removes the alpha channel of - input images without using it (not necessarily a good idea) - added "swap_alpha" transformation, which puts the alpha channel in front - of the color bytes instead of after - removed all implicit variable tests which assume NULL == 0 (I think) - changed several variables to "png_size_t" to show 16/32-bit limitations - added new pCAL chunk read/write support - added experimental filter selection weighting (Greg Roelofs) - removed old png_set_rgbx() and png_set_xrgb() functions that have been - obsolete for about 2 years now (use png_set_filler() instead) - added macros to read 16- and 32-bit ints directly from buffer, to be - used only on those systems that support it (namely PowerPC and 680x0) - With some testing, this may become the default for MACOS/PPC systems. - only calculate CRC on data if we are going to use it - added macros for zTXt compression type PNG_zTXt_COMPRESSION_??? - added macros for simple libpng debugging output selectable at compile time - removed PNG_READ_END_MODE in progressive reader (Smarasderagd) - more description of info_struct in libpng.txt and png.h - more instructions in example.c - more chunk types tested in pngtest.c - renamed pngrcb.c to pngset.c, and all png_read_ functions to be - png_set_.

Get libpng-*.tar.gz, -libpng-*.tar.lzma, or libpng-*.tar.bz2 if you want UNIX-style line -endings in the text files, or lpng*.7z or lpng*.zip if you want DOS-style -line endings. You can get UNIX-style line endings from the *.zip file -by using "unzip -a" but there seems to be no simple way to recover -UNIX-style line endings from the *.7z file. The *.tar.lzma file is -recommended for *NIX users instead. - -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 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 do not make current programs -that access the info struct directly incompatible with the new -library. However, 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. - -The changes made to the library, and bugs fixed are based on discussions -on the png-mng-implement mailing list -and not on material submitted privately to Guy, Andreas, or Glenn. They will -forward any good suggestions to the list. - -For a detailed description on using libpng, read libpng.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 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 -ftp://ftp.simplesystems.org/pub/png/src/ - -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.sf.net in the -[DOWNLOAD] area, and on CompuServe, Lib 20 (PNG SUPPORT) -at GO GRAPHSUP. If you can't find it in any of those places, -e-mail me, and I'll help you find it. - -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 group. - -Send comments/corrections/commendations to png-mng-implement at lists.sf.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-mng-implement list, however. - -Please do not send general questions about PNG. Send them to -the (png-mng-misc at lists.sourceforge.net, subscription required, visit -https://lists.sourceforge.net/lists/listinfo/png-mng-implement to subscribe) -On the other hand, -please do not send libpng questions to that address, send them to me -or to the png-mng-implement list. I'll -get them in the end anyway. 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 twelve years now, and it is official and -finished. If you have suggestions for libpng, however, I'll -gladly listen.

Y2K compliance in libpng: - ========================= - - December 18, 2008 - - Since the PNG Development group is an ad-hoc body, we can't make - an official declaration. - - This is your unofficial assurance that libpng from version 0.71 and - upward through 1.2.34 are Y2K compliant. It is my belief that earlier - versions were also Y2K compliant. - - Libpng only has three year fields. One is a 2-byte unsigned integer - that will hold years up to 65535. The other two hold the date in text - format, and will hold years up to 9999. - - The integer is - "png_uint_16 year" in png_time_struct. - - The strings are - "png_charp time_buffer" in png_struct and - "near_time_buffer", which is a local character string in png.c. - - There are seven time-related functions: - - png_convert_to_rfc_1123() in png.c - (formerly png_convert_to_rfc_1152() in error) - png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c - png_convert_from_time_t() in pngwrite.c - png_get_tIME() in pngget.c - png_handle_tIME() in pngrutil.c, called in pngread.c - png_set_tIME() in pngset.c - png_write_tIME() in pngwutil.c, called in pngwrite.c - - All appear to handle dates properly in a Y2K environment. 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 applications using - libpng are not passing 4-digit years into the png_convert_to_rfc_1123() - 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. The libpng documentation has always - stated that it works with 4-digit years, and the APIs have been - documented as such. - - The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned - integer to hold the year, and can hold years as large as 65535. - - zlib, upon which libpng depends, is also Y2K compliant. It contains - no date-related code. - - - Glenn Randers-Pehrson - libpng maintainer - PNG Development Group diff --git a/Build/source/libs/libpng/libpng-1.2.34/autogen.sh b/Build/source/libs/libpng/libpng-1.2.34/autogen.sh deleted file mode 100755 index 77b63087c8b..00000000000 --- a/Build/source/libs/libpng/libpng-1.2.34/autogen.sh +++ /dev/null @@ -1,25 +0,0 @@ -#! /bin/sh -# a quick hack script to generate necessary files from -# auto* tools. -# -# WARNING: if you run this you will change the versions -# of the tools which are used and, maybe, required! - touch Makefile.am configure.ac -{ - echo "running libtoolize" >&2 - libtoolize --force --copy --automake -} && { - echo "running aclocal" >&2 - aclocal -} && { - echo "running autoheader [ignore the warnings]" >&2 - autoheader -} && { - echo "running automake" >&2 - automake --force-missing --foreign -a -c -} && { - echo "running autoconf" >&2 - autoconf -} && - echo "autogen complete" >&2 || - echo "ERROR: autogen.sh failed, autogen is incomplete" >&2 diff --git a/Build/source/libs/libpng/libpng-1.2.34/config.guess b/Build/source/libs/libpng/libpng-1.2.34/config.guess deleted file mode 100755 index ca2a03ca4f1..00000000000 --- a/Build/source/libs/libpng/libpng-1.2.34/config.guess +++ /dev/null @@ -1,1526 +0,0 @@ -#! /bin/sh -# Attempt to guess a canonical system name. -# Copyright (C) 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, -# 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008 -# Free Software Foundation, Inc. - -timestamp='2008-01-08' - -# This file 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.

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.

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 == "$disk:[dir]wpng.exe" - - All three will print a basic usage screen when run without any command- - line arguments; see the book for more details. Note that the options - style is Unix-like, i.e., preceded by "-" rather than "/". - - -RUNNING THE PROGRAMS: (VERY) BRIEF INTRO - - rpng is a simple PNG viewer that can display transparent PNGs with a - specified background color; for example, - - rpng -bgcolor #ff0000 toucan.png - - would display the image with a red background. rpng2 is a progressive - viewer that simulates a web browser in some respects; it can display - images against either a background color or a dynamically generated - background image. For example: - - rpng2 -bgpat 16 toucan.png - - wpng is a purely command-line image converter from binary PBMPLUS/NetPBM - format (.pgm or .ppm) to PNG; for example, - - wpng -time < toucan-notrans.ppm > toucan-notrans.png - - would convert the specified PPM file (using redirection) to PNG, auto- - matically setting the PNG modification-time chunk. - - All options can be abbreviated to the shortest unique value; for example, - "-bgc" for -bgcolor (versus "-bgp" for -bgpat), or "-g" for -gamma. diff --git a/Build/source/libs/libpng/libpng-1.2.34/contrib/gregbook/makevms.com b/Build/source/libs/libpng/libpng-1.2.34/contrib/gregbook/makevms.com deleted file mode 100644 index bd37dc0d772..00000000000 --- a/Build/source/libs/libpng/libpng-1.2.34/contrib/gregbook/makevms.com +++ /dev/null @@ -1,132 +0,0 @@ -$!------------------------------------------------------------------------------ -$! make "PNG: The Definitive Guide" demo programs (for X) under OpenVMS -$! -$!

- -License -------- - -Permission to use, copy, modify, and distribute this software and -its documentation for any purpose and without fee is hereby granted, -provided that the above copyright notice appear in all copies and -that both that copyright notice and this permission notice appear in -supporting documentation. This software is provided "as is" without -express or implied warranty. - - -Some history ------------- -Soon after the creation of PNG in 1995, the need was felt for a set of -pnmtopng / pngtopnm utilities. Independantly Alexander Lehmann and I -(Willem van Schaik) started such a project. Luckily we discovered this -and merged the two together into pnmtopng.tar.gz, which is available -from a/o ftp://ftp.simplesystems.org/pub/libpng/png/. - -These two utilities have many, many options and make use of most of the -features of PNG, like gamma, alpha, sbit, text-chunks, etc. This makes -the utilities quite complex and by now not anymore very maintainable. -When we wrote these programs, libpng was still in an early stage. -Therefore, lots of the functionality that we put in our software can now -be done using transform-functions in libpng. - -Finally, to compile these programs, you need to have installed and -compiled three libraries: libpng, zlib and netpbm. Especially the latter -makes the whole setup a bit bulky. But that's unavoidable given the many -features of pnmtopng. - - -What now --------- -At this moment libpng is in a very stable state and can do much of the -work done in pnmtopng. Also, pnmtopng needs to be upgraded to the new -interface of libpng. Hence, it is time for a rewrite from the ground up -of pnmtopng and pngtopnm. This will happen in the near future (stay -tuned). The new package will get a different name to distinguish it from -the old one: PngPlus. - -To experiment a bit with the new interface of libpng, I started off with -a small prototype that contains only the basic functionality. It doesn't -have any of the options to read or write special chunks and it will do -no gamma correction. But this makes it also a simple program that is -quite easy to understand and can serve well as a template for other -software developments. (By now there are of course a couple of programs, -like Greg Roelofs' rpng/wpng, that can be used just as good.) - - -Can and can not ---------------- -As this is the small brother of the future PngPlus, I called this fellow -PngMinus. Because I started this development in good-old Turbo-C, I -avoided the use the netpbm library, which requires DOS extenders. Again, -another reason to call it PngMinus (minus netpbm :-). So, part of the -program are some elementary routines to read / write pgm- and ppm-files. -It does not read b&w pbm-files. - -The downside of this approach is that you can not use them on images -that require blocks of memory bigger than 64k (the DOS version). For -larger images you will get an out-of-memory error. - -As said before, PngMinus doesn't correct for gamma. When reading -png-files you can do this just as well by piping the output of png2pnm -to pnmgamma, one of the standard PbmPlus tools. This same scenario will -most probably also be followed in the full-blown future PngPlus, with -the addition of course of the possibility to create gamma-chunks when -writing png-files. - -On the other hand it supports alpha-channels. When reading a png-image -you can write the alpha-channel into a pgm-file. And when creating an -RGB+A png-image, you just combine a ppm-file with a corresponding -pgm-file containing the alpha-channel. When reading, transparency chunks -are converted into an alpha-channel and from there on treated the same -way. - -Finally you can opt for writing ascii or binary pgm- and ppm-files. When -the bit-depth is 16, the format will always be ascii. - - -Using it --------- -To distinguish them from pnmtopng and PngPlus, the utilities are named -png2pnm and pnm2png (2 instead of to). The input- and output-files can -be given as parameters or through redirection. Therefore the programs -can be part of a pipe. - -To list the options type "png2pnm -h" or "pnm2png -h". - - -Just like Scandinavian furniture --------------------------------- -You have to put it together yourself. I did test the software under -MS-DOS with Turbo-C 3.0 and under RedHat Linux 4.2 with gcc. In both -cases I used libpng-1.0.4 and zlib-1.1.3. Later versions should be OK, -however some older libpng versions have a bug in pngmem.c when using -Turbo-C 3.0 (see below). - -You can build it using one of the two makefiles (make -f makefile.###) -or use the batch/script files pngminus.bat / pngminus.sh. This assumes -that you have built the libraries in ../libpng and ../zlib. Using Linux, -make sure that you have built libpng with makefile.std and not -makefile.linux (also called .lnx in earlier versions of libpng). The -latter creates a .so shared-library, while the PngMinus makefile assumes -a normal .a static library. - -If you create a ../pngsuite directory and then store the basn####.png -files from PngSuite (http://www.schaik.com/pngsuite/) in there, you can -test in one go the proper functioning of PngMinus, see png2pnm.bat and -pnm2png.bat (or the .sh versions). - - -Warranty -------- -Please, remember that this was just a small experiment to learn a few -things. It will have many unforeseen features . Who said bugs? Use -it when you are in need for something simple or when you want to start -developing your own stuff. - - -The Turbo bug -------------- -** pngmem.old - hptr = (png_byte huge *)((long)(hptr) & 0xfffffff0L); - hptr += 16L; -** pngmem.c - hptr = (png_byte huge *)((long)(hptr) & 0xfffffff0L); - hptr = hptr + 16L; -** - -** pngmem.old - png_ptr->offset_table_ptr[i] = (png_bytep)hptr; - hptr += (png_uint_32)65536L; -** pngmem.c - png_ptr->offset_table_ptr[i] = (png_bytep)hptr; - hptr = hptr + 65536L; -** - - -The end -------- -Willem van Schaik -mailto:willem@schaik.com -http://www.schaik.com/png/ -------- -Oct 1999 - diff --git a/Build/source/libs/libpng/libpng-1.2.34/contrib/pngminus/makefile.std b/Build/source/libs/libpng/libpng-1.2.34/contrib/pngminus/makefile.std deleted file mode 100644 index 2fb061bbe2c..00000000000 --- a/Build/source/libs/libpng/libpng-1.2.34/contrib/pngminus/makefile.std +++ /dev/null @@ -1,65 +0,0 @@ -# Makefile for PngMinus (png2pnm and pnm2png) -# Linux / Unix - -#CC=cc -CC=gcc -LD=$(CC) - -RM=rm -f - -#PNGPATH = /usr/local -#PNGINC = -I$(PNGPATH)/include/libpng12 -#PNGLIB = -L$(PNGPATH)/lib -lpng12 -#PNGLIBS = $(PNGPATH)/lib/libpng12.a -PNGINC = -I../.. -PNGLIB = -L../.. -lpng -PNGLIBS = ../../libpng.a - -#ZPATH = /usr/local -#ZINC = -I$(ZPATH)/include -#ZLIB = -L$(ZPATH)/lib -lz -#ZLIBS = $(ZPATH)/lib/libz.a -ZINC = -I../../../zlib -ZLIB = -L../../../zlib -lz -ZLIBS = ../../../zlib/libz.a - -CFLAGS=-O3 $(PNGINC) $(ZINC) -LDFLAGS=$(PNGLIB) $(ZLIB) -LDFLAGSS=$(PNGLIBS) $(ZLIBS) -C=.c -O=.o -L=.a -E= - -# dependencies - -#all: png2pnm$(E) pnm2png$(E) -all: png2pnm$(E) pnm2png$(E) png2pnm-static$(E) pnm2png-static$(E) - -png2pnm$(O): png2pnm$(C) - $(CC) -c $(CFLAGS) png2pnm$(C) - -png2pnm$(E): png2pnm$(O) - $(LD) -o png2pnm$(E) png2pnm$(O) $(LDFLAGS) -lm - -png2pnm-static$(E): png2pnm$(O) - $(LD) -o png2pnm-static$(E) png2pnm$(O) $(LDFLAGSS) -lm - -pnm2png$(O): pnm2png$(C) - $(CC) -c $(CFLAGS) pnm2png$(C) - -pnm2png$(E): pnm2png$(O) - $(LD) -o pnm2png$(E) pnm2png$(O) $(LDFLAGS) -lm - -pnm2png-static$(E): pnm2png$(O) - $(LD) -o pnm2png-static$(E) pnm2png$(O) $(LDFLAGSS) -lm - -clean: - $(RM) png2pnm$(O) - $(RM) pnm2png$(O) - $(RM) png2pnm$(E) - $(RM) pnm2png$(E) - $(RM) png2pnm-static$(E) - $(RM) pnm2png-static$(E) - -# End of makefile for png2pnm / pnm2png diff --git a/Build/source/libs/libpng/libpng-1.2.34/contrib/pngminus/makefile.tc3 b/Build/source/libs/libpng/libpng-1.2.34/contrib/pngminus/makefile.tc3 deleted file mode 100644 index 404f18d5b15..00000000000 --- a/Build/source/libs/libpng/libpng-1.2.34/contrib/pngminus/makefile.tc3 +++ /dev/null @@ -1,38 +0,0 @@ -# Makefile for PngMinus (png2pnm and pnm2png) -# TurboC++ 3.0 - -CC=tcc -Ic:\tc3\inc -LD=tcc -Lc:\tc3\lib -LB=tlib -RM=del -CP=copy -MODEL=l -CCFLAGS=-O -m$(MODEL) -I..\libpng -I..\zlib -LDFLAGS=-m$(MODEL) -L..\libpng -L..\zlib -C=.c -O=.obj -L=.lib -E=.exe - -# dependencies - -all: png2pnm$(E) pnm2png$(E) - -png2pnm$(O): png2pnm$(C) - $(CC) -c $(CCFLAGS) png2pnm$(C) - -png2pnm$(E): png2pnm$(O) - $(LD) $(LDFLAGS) png2pnm$(O) libpng$(L) zlib$(L) - -pnm2png$(O): pnm2png$(C) - $(CC) -c $(CCFLAGS) pnm2png$(C) - -pnm2png$(E): pnm2png$(O) - $(LD) $(LDFLAGS) pnm2png$(O) libpng$(L) zlib$(L) - -clean: - $(RM) *$(O) - $(RM) *$(E) - -# End of makefile for png2pnm / pnm2png - diff --git a/Build/source/libs/libpng/libpng-1.2.34/contrib/pngminus/makevms.com b/Build/source/libs/libpng/libpng-1.2.34/contrib/pngminus/makevms.com deleted file mode 100644 index 00561bcd0d7..00000000000 --- a/Build/source/libs/libpng/libpng-1.2.34/contrib/pngminus/makevms.com +++ /dev/null @@ -1,92 +0,0 @@ -$!------------------------------------------------------------------------------ -$! make Contrib programs of libpng under OpenVMS -$! -$! -$!

Costello -http://www.nicemice.net/amc/ - -An interface for exception-handling in ANSI C (C89 and subsequent ISO -standards), developed jointly with Cosmin Truta. - - Copyright (c) 2000-2008 Adam M. Costello and Cosmin Truta. - This software may be modified only if its author and version - information is updated accurately, and may be redistributed - only if accompanied by this unaltered notice. Subject to those - restrictions, permission is granted to anyone to do anything - with this software. The copyright holders make no guarantees - regarding this software, and are not responsible for any damage - resulting from its use. - -The cexcept interface is not compatible with and cannot interact -with system exceptions (like division by zero or memory segmentation -violation), compiler-generated exceptions (like C++ exceptions), or -other exception-handling interfaces. - -When using this interface across multiple .c files, do not include -this header file directly. Instead, create a wrapper header file that -includes this header file and then invokes the define_exception_type -macro (see below). The .c files should then include that header file. - -The interface consists of one type, one well-known name, and six macros. - - -define_exception_type(type_name); - - This macro is used like an external declaration. It specifies - the type of object that gets copied from the exception thrower to - the exception catcher. The type_name can be any type that can be - assigned to, that is, a non-constant arithmetic type, struct, union, - or pointer. Examples: - - define_exception_type(int); - - enum exception { out_of_memory, bad_arguments, disk_full }; - define_exception_type(enum exception); - - struct exception { int code; const char *msg; }; - define_exception_type(struct exception); - - Because throwing an exception causes the object to be copied (not - just once, but twice), programmers may wish to consider size when - choosing the exception type. - - -struct exception_context; - - This type may be used after the define_exception_type() macro has - been invoked. A struct exception_context must be known to both - the thrower and the catcher. It is expected that there be one - context for each thread that uses exceptions. It would certainly - be dangerous for multiple threads to access the same context. - One thread can use multiple contexts, but that is likely to be - confusing and not typically useful. The application can allocate - this structure in any way it pleases--automatic, static, or dynamic. - The application programmer should pretend not to know the structure - members, which are subject to change. - - -struct exception_context *the_exception_context; - - The Try/Catch and Throw statements (described below) implicitly - refer to a context, using the name the_exception_context. It is - the application's responsibility to make sure that this name yields - the address of a mutable (non-constant) struct exception_context - wherever those statements are used. Subject to that constraint, the - application may declare a variable of this name anywhere it likes - (inside a function, in a parameter list, or externally), and may - use whatever storage class specifiers (static, extern, etc) or type - qualifiers (const, volatile, etc) it likes. Examples: - - static struct exception_context - * const the_exception_context = &foo; - - { struct exception_context *the_exception_context = bar; ... } - - int blah(struct exception_context *the_exception_context, ...); - - extern struct exception_context the_exception_context[1]; - - The last example illustrates a trick that avoids creating a pointer - object separate from the structure object. - - The name could even be a macro, for example: - - struct exception_context ec_array[numthreads]; - #define the_exception_context (ec_array + thread_id) - - Be aware that the_exception_context is used several times by the - Try/Catch/Throw macros, so it shouldn't be expensive or have side - effects. The expansion must be a drop-in replacement for an - identifier, so it's safest to put parentheses around it. - - -void init_exception_context(struct exception_context *ec); - - For context structures allocated statically (by an external - definition or using the "static" keyword), the implicit - initialization to all zeros is sufficient, but contexts allocated - by other means must be initialized using this macro before they - are used by a Try/Catch statement. It does no harm to initialize - a context more than once (by using this macro on a statically - allocated context, or using this macro twice on the same context), - but a context must not be re-initialized after it has been used by a - Try/Catch statement. - - -Try statement -Catch (expression) statement - - The Try/Catch/Throw macros are capitalized in order to avoid - confusion with the C++ keywords, which have subtly different - semantics. - - A Try/Catch statement has a syntax similar to an if/else statement, - except that the parenthesized expression goes after the second - keyword rather than the first. As with if/else, there are two - clauses, each of which may be a simple statement ending with a - semicolon or a brace-enclosed compound statement. But whereas - the else clause is optional, the Catch clause is required. The - expression must be a modifiable lvalue (something capable of being - assigned to) of the same type (disregarding type qualifiers) that - was passed to define_exception_type(). - - If a Throw that uses the same exception context as the Try/Catch is - executed within the Try clause (typically within a function called - by the Try clause), and the exception is not caught by a nested - Try/Catch statement, then a copy of the exception will be assigned - to the expression, and control will jump to the Catch clause. If no - such Throw is executed, then the assignment is not performed, and - the Catch clause is not executed. - - The expression is not evaluated unless and until the exception is - caught, which is significant if it has side effects, for example: - - Try foo(); - Catch (p[++i].e) { ... } - - IMPORTANT: Jumping into or out of a Try clause (for example via - return, break, continue, goto, longjmp) is forbidden--the compiler - will not complain, but bad things will happen at run-time. Jumping - into or out of a Catch clause is okay, and so is jumping around - inside a Try clause. In many cases where one is tempted to return - from a Try clause, it will suffice to use Throw, and then return - from the Catch clause. Another option is to set a flag variable and - use goto to jump to the end of the Try clause, then check the flag - after the Try/Catch statement. - - IMPORTANT: The values of any non-volatile automatic variables - changed within the Try clause are undefined after an exception is - caught. Therefore, variables modified inside the Try block whose - values are needed later outside the Try block must either use static - storage or be declared with the "volatile" type qualifier. - - -Throw expression; - - A Throw statement is very much like a return statement, except that - the expression is required. Whereas return jumps back to the place - where the current function was called, Throw jumps back to the Catch - clause of the innermost enclosing Try clause. The expression must - be compatible with the type passed to define_exception_type(). The - exception must be caught, otherwise the program may crash. - - Slight limitation: If the expression is a comma-expression, it must - be enclosed in parentheses. - - -Try statement -Catch_anonymous statement - - When the value of the exception is not needed, a Try/Catch statement - can use Catch_anonymous instead of Catch (expression). - - -Everything below this point is for the benefit of the compiler.

We assume that libpng is already installed; see the -INSTALL file for instructions on how to install libpng. - -For examples of libpng usage, see the files "example.c", "pngtest.c", -and the files in the "contrib" directory, all of which are included in the -libpng distribution. - -Libpng was written as a companion to the PNG specification, as a way -of reducing the amount of time and effort it takes to support the PNG -file format in application programs. - -The PNG specification (second edition), November 2003, is available as -a W3C Recommendation and as an ISO Standard (ISO/IEC 15948:2003 (E)) at -. It is technically equivalent -to the PNG specification (second edition) but has some additional material. - -The PNG-1.0 specification is available -as RFC 2083 and as a -W3C Recommendation . - -Some additional chunks are described in the special-purpose public chunks -documents at . - -Other information -about PNG, and the latest version of libpng, can be found at the PNG home -page, . - -Most users will not have to modify the library significantly; advanced -users may want to modify it more. All attempts were made to make it as -complete as possible, while keeping the code easy to understand. -Currently, this library only supports C. Support for other languages -is being considered. - -Libpng has been designed to handle multiple sessions at one time, -to be easily modifiable, to be portable to the vast majority of -machines (ANSI, K&R, 16-, 32-, and 64-bit) available, and to be easy -to use. The ultimate goal of libpng is to promote the acceptance of -the PNG file format in whatever way possible. While there is still -work to be done (see the TODO file), libpng should cover the -majority of the needs of its users. - -Libpng uses zlib for its compression and decompression of PNG files. -Further information about zlib, and the latest version of zlib, can -be found at the zlib home page, . -The zlib compression utility is a general purpose utility that is -useful for more than PNG files, and can be used without libpng. -See the documentation delivered with zlib for more details. -You can usually find the source files for the zlib utility wherever you -find the libpng source files. - -Libpng is thread safe, provided the threads are using different -instances of the structures. Each thread should have its own -png_struct and png_info instances, and thus its own image. -Libpng does not protect itself against two threads using the -same instance of a structure. - -II. Structures - -There are two main structures that are important to libpng, png_struct -and png_info. The first, png_struct, is an internal structure that -will not, for the most part, be used by a user except as the first -variable passed to every libpng function call. - -The png_info structure is designed to provide information about the -PNG file. At one time, the fields of png_info were intended to be -directly accessible to the user. However, this tended to cause problems -with applications using dynamically loaded libraries, and as a result -a set of interface functions for png_info (the png_get_*() and png_set_*() -functions) was developed. The fields of png_info are still available for -older applications, but it is suggested that applications use the new -interfaces if at all possible. - -Applications that do make direct access to the members of png_struct (except -for png_ptr->jmpbuf) must be recompiled whenever the library is updated, -and applications that make direct access to the members of png_info must -be recompiled if they were compiled or loaded with libpng version 1.0.6, -in which the members were in a different order. In version 1.0.7, the -members of the png_info structure reverted to the old order, as they were -in versions 0.97c through 1.0.5. Starting with version 2.0.0, both -structures are going to be hidden, and the contents of the structures will -only be accessible through the png_get/png_set functions. - -The png.h header file is an invaluable reference for programming with libpng. -And while I'm on the topic, make sure you include the libpng header file: - -#include - -III. Reading - -We'll now walk you through the possible functions to call when reading -in a PNG file sequentially, briefly explaining the syntax and purpose -of each one. See example.c and png.h for more detail. While -progressive reading is covered in the next section, you will still -need some of the functions discussed in this section to read a PNG -file. - -Setup - -You will want to do the I/O initialization(*) before you get into libpng, -so if it doesn't work, you don't have much to undo. Of course, you -will also want to insure that you are, in fact, dealing with a PNG -file. Libpng provides a simple check to see if a file is a PNG file. -To use it, pass in the first 1 to 8 bytes of the file to the function -png_sig_cmp(), and it will return 0 if the bytes match the corresponding -bytes of the PNG signature, or nonzero otherwise. Of course, the more bytes -you pass in, the greater the accuracy of the prediction. - -If you are intending to keep the file pointer open for use in libpng, -you must ensure you don't read more than 8 bytes from the beginning -of the file, and you also have to make a call to png_set_sig_bytes_read() -with the number of bytes you read from the beginning. Libpng will -then only check the bytes (if any) that your program didn't read. - -(*): If you are not using the standard I/O functions, you will need -to replace them with custom functions. See the discussion under -Customizing libpng. - - - FILE *fp = fopen(file_name, "rb"); - if (!fp) - { - return (ERROR); - } - fread(header, 1, number, fp); - is_png = !png_sig_cmp(header, 0, number); - if (!is_png) - { - return (NOT_PNG); - } - - -Next, png_struct and png_info need to be allocated and initialized. In -order to ensure that the size of these structures is correct even with a -dynamically linked libpng, there are functions to initialize and -allocate the structures. We also pass the library version, optional -pointers to error handling functions, and a pointer to a data struct for -use by the error functions, if necessary (the pointer and functions can -be NULL if the default error handlers are to be used). See the section -on Changes to Libpng below regarding the old initialization functions. -The structure allocation functions quietly return NULL if they fail to -create the structure, so your application should check for that. - - png_structp png_ptr = png_create_read_struct - (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr, - user_error_fn, user_warning_fn); - if (!png_ptr) - return (ERROR); - - png_infop info_ptr = png_create_info_struct(png_ptr); - if (!info_ptr) - { - png_destroy_read_struct(&png_ptr, - (png_infopp)NULL, (png_infopp)NULL); - return (ERROR); - } - - png_infop end_info = png_create_info_struct(png_ptr); - if (!end_info) - { - png_destroy_read_struct(&png_ptr, &info_ptr, - (png_infopp)NULL); - return (ERROR); - } - -If you want to use your own memory allocation routines, -define PNG_USER_MEM_SUPPORTED and use -png_create_read_struct_2() instead of png_create_read_struct(): - - png_structp png_ptr = png_create_read_struct_2 - (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr, - user_error_fn, user_warning_fn, (png_voidp) - user_mem_ptr, user_malloc_fn, user_free_fn); - -The error handling routines passed to png_create_read_struct() -and the memory alloc/free routines passed to png_create_struct_2() -are only necessary if you are not using the libpng supplied error -handling and memory alloc/free functions. - -When libpng encounters an error, it expects to longjmp back -to your routine. Therefore, you will need to call setjmp and pass -your png_jmpbuf(png_ptr). If you read the file from different -routines, you will need to update the jmpbuf field every time you enter -a new routine that will call a png_*() function. - -See your documentation of setjmp/longjmp for your compiler for more -information on setjmp/longjmp. See the discussion on libpng error -handling in the Customizing Libpng section below for more information -on the libpng error handling. If an error occurs, and libpng longjmp's -back to your setjmp, you will want to call png_destroy_read_struct() to -free any memory. - - if (setjmp(png_jmpbuf(png_ptr))) - { - png_destroy_read_struct(&png_ptr, &info_ptr, - &end_info); - fclose(fp); - return (ERROR); - } - -If you would rather avoid the complexity of setjmp/longjmp issues, -you can compile libpng with PNG_SETJMP_NOT_SUPPORTED, in which case -errors will result in a call to PNG_ABORT() which defaults to abort(). - -Now you need to set up the input code. The default for libpng is to -use the C function fread(). If you use this, you will need to pass a -valid FILE * in the function png_init_io(). Be sure that the file is -opened in binary mode. If you wish to handle reading data in another -way, you need not call the png_init_io() function, but you must then -implement the libpng I/O methods discussed in the Customizing Libpng -section below. - - png_init_io(png_ptr, fp); - -If you had previously opened the file and read any of the signature from -the beginning in order to see if this was a PNG file, you need to let -libpng know that there are some bytes missing from the start of the file. - - png_set_sig_bytes(png_ptr, number); - -Setting up callback code - -You can set up a callback function to handle any unknown chunks in the -input stream. You must supply the function - - read_chunk_callback(png_ptr ptr, - png_unknown_chunkp chunk); - { - /* The unknown chunk structure contains your - chunk data, along with similar data for any other - unknown chunks: */ - - png_byte name[5]; - png_byte *data; - png_size_t size; - - /* Note that libpng has already taken care of - the CRC handling */ - - /* put your code here. Search for your chunk in the - unknown chunk structure, process it, and return one - of the following: */ - - return (-n); /* chunk had an error */ - return (0); /* did not recognize */ - return (n); /* success */ - } - -(You can give your function another name that you like instead of -"read_chunk_callback") - -To inform libpng about your function, use - - png_set_read_user_chunk_fn(png_ptr, user_chunk_ptr, - read_chunk_callback); - -This names not only the callback function, but also a user pointer that -you can retrieve with - - png_get_user_chunk_ptr(png_ptr); - -If you call the png_set_read_user_chunk_fn() function, then all unknown -chunks will be saved when read, in case your callback function will need -one or more of them. This behavior can be changed with the -png_set_keep_unknown_chunks() function, described below. - -At this point, you can set up a callback function that will be -called after each row has been read, which you can use to control -a progress meter or the like. It's demonstrated in pngtest.c. -You must supply a function - - void read_row_callback(png_ptr ptr, png_uint_32 row, - int pass); - { - /* put your code here */ - } - -(You can give it another name that you like instead of "read_row_callback") - -To inform libpng about your function, use - - png_set_read_status_fn(png_ptr, read_row_callback); - -Width and height limits - -The PNG specification allows the width and height of an image to be as -large as 2^31-1 (0x7fffffff), or about 2.147 billion rows and columns. -Since very few applications really need to process such large images, -we have imposed an arbitrary 1-million limit on rows and columns. -Larger images will be rejected immediately with a png_error() call. If -you wish to override this limit, you can use - - png_set_user_limits(png_ptr, width_max, height_max); - -to set your own limits, or use width_max = height_max = 0x7fffffffL -to allow all valid dimensions (libpng may reject some very large images -anyway because of potential buffer overflow conditions). - -You should put this statement after you create the PNG structure and -before calling png_read_info(), png_read_png(), or png_process_data(). -If you need to retrieve the limits that are being applied, use - - width_max = png_get_user_width_max(png_ptr); - height_max = png_get_user_height_max(png_ptr); - -Unknown-chunk handling - -Now you get to set the way the library processes unknown chunks in the -input PNG stream. Both known and unknown chunks will be read. Normal -behavior is that known chunks will be parsed into information in -various info_ptr members while unknown chunks will be discarded. This -behavior can be wasteful if your application will never use some known -chunk types. To change this, you can call: - - png_set_keep_unknown_chunks(png_ptr, keep, - chunk_list, num_chunks); - keep - 0: default unknown chunk handling - 1: ignore; do not keep - 2: keep only if safe-to-copy - 3: keep even if unsafe-to-copy - You can use these definitions: - PNG_HANDLE_CHUNK_AS_DEFAULT 0 - PNG_HANDLE_CHUNK_NEVER 1 - PNG_HANDLE_CHUNK_IF_SAFE 2 - PNG_HANDLE_CHUNK_ALWAYS 3 - chunk_list - list of chunks affected (a byte string, - five bytes per chunk, NULL or '\0' if - num_chunks is 0) - num_chunks - number of chunks affected; if 0, all - unknown chunks are affected. If nonzero, - only the chunks in the list are affected - -Unknown chunks declared in this way will be saved as raw data onto a -list of png_unknown_chunk structures. If a chunk that is normally -known to libpng is named in the list, it will be handled as unknown, -according to the "keep" directive. If a chunk is named in successive -instances of png_set_keep_unknown_chunks(), the final instance will -take precedence. The IHDR and IEND chunks should not be named in -chunk_list; if they are, libpng will process them normally anyway. - -Here is an example of the usage of png_set_keep_unknown_chunks(), -where the private "vpAg" chunk will later be processed by a user chunk -callback function: - - png_byte vpAg[5]={118, 112, 65, 103, (png_byte) '\0'}; - - #if defined(PNG_UNKNOWN_CHUNKS_SUPPORTED) - png_byte unused_chunks[]= - { - 104, 73, 83, 84, (png_byte) '\0', /* hIST */ - 105, 84, 88, 116, (png_byte) '\0', /* iTXt */ - 112, 67, 65, 76, (png_byte) '\0', /* pCAL */ - 115, 67, 65, 76, (png_byte) '\0', /* sCAL */ - 115, 80, 76, 84, (png_byte) '\0', /* sPLT */ - 116, 73, 77, 69, (png_byte) '\0', /* tIME */ - }; - #endif - - ... - - #if defined(PNG_UNKNOWN_CHUNKS_SUPPORTED) - /* ignore all unknown chunks: */ - png_set_keep_unknown_chunks(read_ptr, 1, NULL, 0); - /* except for vpAg: */ - png_set_keep_unknown_chunks(read_ptr, 2, vpAg, 1); - /* also ignore unused known chunks: */ - png_set_keep_unknown_chunks(read_ptr, 1, unused_chunks, - (int)sizeof(unused_chunks)/5); - #endif - - -The high-level read interface - -At this point there are two ways to proceed; through the high-level -read interface, or through a sequence of low-level read operations. -You can use the high-level interface if (a) you are willing to read -the entire image into memory, and (b) the input transformations -you want to do are limited to the following set: - - PNG_TRANSFORM_IDENTITY No transformation - PNG_TRANSFORM_STRIP_16 Strip 16-bit samples to - 8 bits - PNG_TRANSFORM_STRIP_ALPHA Discard the alpha channel - PNG_TRANSFORM_PACKING Expand 1, 2 and 4-bit - samples to bytes - PNG_TRANSFORM_PACKSWAP Change order of packed - pixels to LSB first - PNG_TRANSFORM_EXPAND Perform set_expand() - PNG_TRANSFORM_INVERT_MONO Invert monochrome images - PNG_TRANSFORM_SHIFT Normalize pixels to the - sBIT depth - PNG_TRANSFORM_BGR Flip RGB to BGR, RGBA - to BGRA - PNG_TRANSFORM_SWAP_ALPHA Flip RGBA to ARGB or GA - to AG - PNG_TRANSFORM_INVERT_ALPHA Change alpha from opacity - to transparency - PNG_TRANSFORM_SWAP_ENDIAN Byte-swap 16-bit samples - -(This excludes setting a background color, doing gamma transformation, -dithering, and setting filler.) If this is the case, simply do this: - - png_read_png(png_ptr, info_ptr, png_transforms, NULL) - -where png_transforms is an integer containing the bitwise OR of -some set of transformation flags. This call is equivalent to png_read_info(), -followed the set of transformations indicated by the transform mask, -then png_read_image(), and finally png_read_end(). - -(The final parameter of this call is not yet used. Someday it might point -to transformation parameters required by some future input transform.) - -You must use png_transforms and not call any png_set_transform() functions -when you use png_read_png(). - -After you have called png_read_png(), you can retrieve the image data -with - - row_pointers = png_get_rows(png_ptr, info_ptr); - -where row_pointers is an array of pointers to the pixel data for each row: - - png_bytep row_pointers[height]; - -If you know your image size and pixel size ahead of time, you can allocate -row_pointers prior to calling png_read_png() with - - if (height > PNG_UINT_32_MAX/png_sizeof(png_byte)) - png_error (png_ptr, - "Image is too tall to process in memory"); - if (width > PNG_UINT_32_MAX/pixel_size) - png_error (png_ptr, - "Image is too wide to process in memory"); - row_pointers = png_malloc(png_ptr, - height*png_sizeof(png_bytep)); - for (int i=0; i) and -png_get_(png_ptr, info_ptr, ...) functions return non-zero if the -data has been read, or zero if it is missing. The parameters to the -png_get_ are set directly if they are simple data types, or a pointer -into the info_ptr is returned for any complex types. - - png_get_PLTE(png_ptr, info_ptr, &palette, - &num_palette); - palette - the palette for the file - (array of png_color) - num_palette - number of entries in the palette - - png_get_gAMA(png_ptr, info_ptr, &gamma); - gamma - the gamma the file is written - at (PNG_INFO_gAMA) - - png_get_sRGB(png_ptr, info_ptr, &srgb_intent); - srgb_intent - the rendering intent (PNG_INFO_sRGB) - The presence of the sRGB chunk - means that the pixel data is in the - sRGB color space.

Be careful with trusting -rowbytes, as some of the transformations could increase the space -needed to hold a row (expand, filler, gray_to_rgb, etc.). -See png_read_update_info(), below. - -A quick word about text_ptr and num_text. PNG stores comments in -keyword/text pairs, one pair per chunk, with no limit on the number -of text chunks, and a 2^31 byte limit on their size. While there are -suggested keywords, there is no requirement to restrict the use to these -strings. It is strongly suggested that keywords and text be sensible -to humans (that's the point), so don't use abbreviations. Non-printing -symbols are not allowed. See the PNG specification for more details. -There is also no requirement to have text after the keyword. - -Keywords should be limited to 79 Latin-1 characters without leading or -trailing spaces, but non-consecutive spaces are allowed within the -keyword. It is possible to have the same keyword any number of times. -The text_ptr is an array of png_text structures, each holding a -pointer to a language string, a pointer to a keyword and a pointer to -a text string. The text string, language code, and translated -keyword may be empty or NULL pointers. The keyword/text -pairs are put into the array in the order that they are received. -However, some or all of the text chunks may be after the image, so, to -make sure you have read all the text chunks, don't mess with these -until after you read the stuff after the image. This will be -mentioned again below in the discussion that goes with png_read_end(). - -Input transformations - -After you've read the header information, you can set up the library -to handle any special transformations of the image data. The various -ways to transform the data will be described in the order that they -should occur. This is important, as some of these change the color -type and/or bit depth of the data, and some others only work on -certain color types and bit depths. Even though each transformation -checks to see if it has data that it can do something with, you should -make sure to only enable a transformation if it will be valid for the -data. For example, don't swap red and blue on grayscale data. - -The colors used for the background and transparency values should be -supplied in the same format/depth as the current image data. They -are stored in the same format/depth as the image data in a bKGD or tRNS -chunk, so this is what libpng expects for this data. The colors are -transformed to keep in sync with the image data when an application -calls the png_read_update_info() routine (see below). - -Data will be decoded into the supplied row buffers packed into bytes -unless the library has been told to transform it into another format. -For example, 4 bit/pixel paletted or grayscale data will be returned -2 pixels/byte with the leftmost pixel in the high-order bits of the -byte, unless png_set_packing() is called. 8-bit RGB data will be stored -in RGB RGB RGB format unless png_set_filler() or png_set_add_alpha() -is called to insert filler bytes, either before or after each RGB triplet. -16-bit RGB data will be returned RRGGBB RRGGBB, with the most significant -byte of the color value first, unless png_set_strip_16() is called to -transform it to regular RGB RGB triplets, or png_set_filler() or -png_set_add alpha() is called to insert filler bytes, either before or -after each RRGGBB triplet. Similarly, 8-bit or 16-bit grayscale data can -be modified with -png_set_filler(), png_set_add_alpha(), or png_set_strip_16(). - -The following code transforms grayscale images of less than 8 to 8 bits, -changes paletted images to RGB, and adds a full alpha channel if there is -transparency information in a tRNS chunk. This is most useful on -grayscale images with bit depths of 2 or 4 or if there is a multiple-image -viewing application that wishes to treat all images in the same way. - - if (color_type == PNG_COLOR_TYPE_PALETTE) - png_set_palette_to_rgb(png_ptr); - - if (color_type == PNG_COLOR_TYPE_GRAY && - bit_depth < 8) png_set_expand_gray_1_2_4_to_8(png_ptr); - - if (png_get_valid(png_ptr, info_ptr, - PNG_INFO_tRNS)) png_set_tRNS_to_alpha(png_ptr); - -These three functions are actually aliases for png_set_expand(), added -in libpng version 1.0.4, with the function names expanded to improve code -readability. In some future version they may actually do different -things. - -As of libpng version 1.2.9, png_set_expand_gray_1_2_4_to_8() was -added. It expands the sample depth without changing tRNS to alpha. -At the same time, png_set_gray_1_2_4_to_8() was deprecated, and it -will be removed from a future version. - - -PNG can have files with 16 bits per channel. If you only can handle -8 bits per channel, this will strip the pixels down to 8 bit. - - if (bit_depth == 16) - png_set_strip_16(png_ptr); - -If, for some reason, you don't need the alpha channel on an image, -and you want to remove it rather than combining it with the background -(but the image author certainly had in mind that you *would* combine -it with the background, so that's what you should probably do): - - if (color_type & PNG_COLOR_MASK_ALPHA) - png_set_strip_alpha(png_ptr); - -In PNG files, the alpha channel in an image -is the level of opacity. If you need the alpha channel in an image to -be the level of transparency instead of opacity, you can invert the -alpha channel (or the tRNS chunk data) after it's read, so that 0 is -fully opaque and 255 (in 8-bit or paletted images) or 65535 (in 16-bit -images) is fully transparent, with - - png_set_invert_alpha(png_ptr); - -PNG files pack pixels of bit depths 1, 2, and 4 into bytes as small as -they can, resulting in, for example, 8 pixels per byte for 1 bit -files. This code expands to 1 pixel per byte without changing the -values of the pixels: - - if (bit_depth < 8) - png_set_packing(png_ptr); - -PNG files have possible bit depths of 1, 2, 4, 8, and 16. All pixels -stored in a PNG image have been "scaled" or "shifted" up to the next -higher possible bit depth (e.g. from 5 bits/sample in the range [0,31] to -8 bits/sample in the range [0, 255]). However, it is also possible to -convert the PNG pixel data back to the original bit depth of the image. -This call reduces the pixels back down to the original bit depth: - - png_color_8p sig_bit; - - if (png_get_sBIT(png_ptr, info_ptr, &sig_bit)) - png_set_shift(png_ptr, sig_bit); - -PNG files store 3-color pixels in red, green, blue order. This code -changes the storage of the pixels to blue, green, red: - - if (color_type == PNG_COLOR_TYPE_RGB || - color_type == PNG_COLOR_TYPE_RGB_ALPHA) - png_set_bgr(png_ptr); - -PNG files store RGB pixels packed into 3 or 6 bytes. This code expands them -into 4 or 8 bytes for windowing systems that need them in this format: - - if (color_type == PNG_COLOR_TYPE_RGB) - png_set_filler(png_ptr, filler, PNG_FILLER_BEFORE); - -where "filler" is the 8 or 16-bit number to fill with, and the location is -either PNG_FILLER_BEFORE or PNG_FILLER_AFTER, depending upon whether -you want the filler before the RGB or after. This transformation -does not affect images that already have full alpha channels. To add an -opaque alpha channel, use filler=0xff or 0xffff and PNG_FILLER_AFTER which -will generate RGBA pixels. - -Note that png_set_filler() does not change the color type. If you want -to do that, you can add a true alpha channel with - - if (color_type == PNG_COLOR_TYPE_RGB || - color_type == PNG_COLOR_TYPE_GRAY) - png_set_add_alpha(png_ptr, filler, PNG_FILLER_AFTER); - -where "filler" contains the alpha value to assign to each pixel. -This function was added in libpng-1.2.7. - -If you are reading an image with an alpha channel, and you need the -data as ARGB instead of the normal PNG format RGBA: - - if (color_type == PNG_COLOR_TYPE_RGB_ALPHA) - png_set_swap_alpha(png_ptr); - -For some uses, you may want a grayscale image to be represented as -RGB.

The row data is simply -raw byte data for all forms of images. As the actual allocation -varies among applications, no example will be given.

If you are -allocating enough memory to hold the whole image, you can just -call png_read_image() and libpng will read in all the image data -and put it in the memory area supplied. You will need to pass in -an array of pointers to each row. - -This function automatically handles interlacing, so you don't need -to call png_set_interlace_handling() or call this function multiple -times, or any of that other stuff necessary with png_read_rows(). - - png_read_image(png_ptr, row_pointers); - -where row_pointers is: - - png_bytep row_pointers[height]; - -You can point to void or char or whatever you use for pixels. - -If you don't want to read in the whole image at once, you can -use png_read_rows() instead. If there is no interlacing (check -interlace_type == PNG_INTERLACE_NONE), this is simple: - - png_read_rows(png_ptr, row_pointers, NULL, - number_of_rows); - -where row_pointers is the same as in the png_read_image() call. - -If you are doing this just one row at a time, you can do this with -a single row_pointer instead of an array of row_pointers: - - png_bytep row_pointer = row; - png_read_row(png_ptr, row_pointer, NULL); - -If the file is interlaced (interlace_type != 0 in the IHDR chunk), things -get somewhat harder. The only current (PNG Specification version 1.2) -interlacing type for PNG is (interlace_type == PNG_INTERLACE_ADAM7) -is a somewhat complicated 2D interlace scheme, known as Adam7, that -breaks down an image into seven smaller images of varying size, based -on an 8x8 grid. - -libpng can fill out those images or it can give them to you "as is". -If you want them filled out, there are two ways to do that. The one -mentioned in the PNG specification is to expand each pixel to cover -those pixels that have not been read yet (the "rectangle" method). -This results in a blocky image for the first pass, which gradually -smooths out as more pixels are read. The other method is the "sparkle" -method, where pixels are drawn only in their final locations, with the -rest of the image remaining whatever colors they were initialized to -before the start of the read. The first method usually looks better, -but tends to be slower, as there are more pixels to put in the rows. - -If you don't want libpng to handle the interlacing details, just call -png_read_rows() seven times to read in all seven images. Each of the -images is a valid image by itself, or they can all be combined on an -8x8 grid to form a single image (although if you intend to combine them -you would be far better off using the libpng interlace handling). - -The first pass will return an image 1/8 as wide as the entire image -(every 8th column starting in column 0) and 1/8 as high as the original -(every 8th row starting in row 0), the second will be 1/8 as wide -(starting in column 4) and 1/8 as high (also starting in row 0). The -third pass will be 1/4 as wide (every 4th pixel starting in column 0) and -1/8 as high (every 8th row starting in row 4), and the fourth pass will -be 1/4 as wide and 1/4 as high (every 4th column starting in column 2, -and every 4th row starting in row 0). The fifth pass will return an -image 1/2 as wide, and 1/4 as high (starting at column 0 and row 2), -while the sixth pass will be 1/2 as wide and 1/2 as high as the original -(starting in column 1 and row 0). The seventh and final pass will be as -wide as the original, and 1/2 as high, containing all of the odd -numbered scanlines. Phew! - -If you want libpng to expand the images, call this before calling -png_start_read_image() or png_read_update_info(): - - if (interlace_type == PNG_INTERLACE_ADAM7) - number_of_passes - = png_set_interlace_handling(png_ptr); - -This will return the number of passes needed. Currently, this -is seven, but may change if another interlace type is added. -This function can be called even if the file is not interlaced, -where it will return one pass. - -If you are not going to display the image after each pass, but are -going to wait until the entire image is read in, use the sparkle -effect. This effect is faster and the end result of either method -is exactly the same. If you are planning on displaying the image -after each pass, the "rectangle" effect is generally considered the -better looking one. - -If you only want the "sparkle" effect, just call png_read_rows() as -normal, with the third parameter NULL. Make sure you make pass over -the image number_of_passes times, and you don't change the data in the -rows between calls. You can change the locations of the data, just -not the data. Each pass only writes the pixels appropriate for that -pass, and assumes the data from previous passes is still valid. - - png_read_rows(png_ptr, row_pointers, NULL, - number_of_rows); - -If you only want the first effect (the rectangles), do the same as -before except pass the row buffer in the third parameter, and leave -the second parameter NULL. - - png_read_rows(png_ptr, NULL, row_pointers, - number_of_rows); - -Finishing a sequential read - -After you are finished reading the image through the -low-level interface, you can finish reading the file. If you are -interested in comments or time, which may be stored either before or -after the image data, you should pass the separate png_info struct if -you want to keep the comments from before and after the image -separate. If you are not interested, you can pass NULL. - - png_read_end(png_ptr, end_info); - -When you are done, you can free all memory allocated by libpng like this: - - png_destroy_read_struct(&png_ptr, &info_ptr, - &end_info); - -It is also possible to individually free the info_ptr members that -point to libpng-allocated storage with the following function: - - png_free_data(png_ptr, info_ptr, mask, seq) - mask - identifies data to be freed, a mask - containing the bitwise OR of one or - more of - PNG_FREE_PLTE, PNG_FREE_TRNS, - PNG_FREE_HIST, PNG_FREE_ICCP, - PNG_FREE_PCAL, PNG_FREE_ROWS, - PNG_FREE_SCAL, PNG_FREE_SPLT, - PNG_FREE_TEXT, PNG_FREE_UNKN, - or simply PNG_FREE_ALL - seq - sequence number of item to be freed - (-1 for all items) - -This function may be safely called when the relevant storage has -already been freed, or has not yet been allocated, or was allocated -by the user and not by libpng, and will in those -cases do nothing.

If "seq" is not --1, and multiple items are allowed for the data type identified in -the mask, such as text or sPLT, only the n'th item in the structure -is freed, where n is "seq". - -The default behavior is only to free data that was allocated internally -by libpng. This can be changed, so that libpng will not free the data, -or so that it will free data that was allocated by the user with png_malloc() -or png_zalloc() and passed in via a png_set_*() function, with - - png_data_freer(png_ptr, info_ptr, freer, mask) - mask - which data elements are affected - same choices as in png_free_data() - freer - one of - PNG_DESTROY_WILL_FREE_DATA - PNG_SET_WILL_FREE_DATA - PNG_USER_WILL_FREE_DATA - -This function only affects data that has already been allocated. -You can call this function after reading the PNG data but before calling -any png_set_*() functions, to control whether the user or the png_set_*() -function is responsible for freeing any existing data that might be present, -and again after the png_set_*() functions to control whether the user -or png_destroy_*() is supposed to free the data. When the user assumes -responsibility for libpng-allocated data, the application must use -png_free() to free it, and when the user transfers responsibility to libpng -for data that the user has allocated, the user must have used png_malloc() -or png_zalloc() to allocate it. - -If you allocated your row_pointers in a single block, as suggested above in -the description of the high level read interface, you must not transfer -responsibility for freeing it to the png_set_rows or png_read_destroy function, -because they would also try to free the individual row_pointers[i]. - -If you allocated text_ptr.text, text_ptr.lang, and text_ptr.translated_keyword -separately, do not transfer responsibility for freeing text_ptr to libpng, -because when libpng fills a png_text structure it combines these members with -the key member, and png_free_data() will free only text_ptr.key.

See the discussion under Customizing libpng. - - FILE *fp = fopen(file_name, "wb"); - if (!fp) - { - return (ERROR); - } - -Next, png_struct and png_info need to be allocated and initialized. -As these can be both relatively large, you may not want to store these -on the stack, unless you have stack space to spare. Of course, you -will want to check if they return NULL. If you are also reading, -you won't want to name your read structure and your write structure -both "png_ptr"; you can call them anything you like, such as -"read_ptr" and "write_ptr". Look at pngtest.c, for example. - - png_structp png_ptr = png_create_write_struct - (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr, - user_error_fn, user_warning_fn); - if (!png_ptr) - return (ERROR); - - png_infop info_ptr = png_create_info_struct(png_ptr); - if (!info_ptr) - { - png_destroy_write_struct(&png_ptr, - (png_infopp)NULL); - return (ERROR); - } - -If you want to use your own memory allocation routines, -define PNG_USER_MEM_SUPPORTED and use -png_create_write_struct_2() instead of png_create_write_struct(): - - png_structp png_ptr = png_create_write_struct_2 - (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr, - user_error_fn, user_warning_fn, (png_voidp) - user_mem_ptr, user_malloc_fn, user_free_fn); - -After you have these structures, you will need to set up the -error handling. When libpng encounters an error, it expects to -longjmp() back to your routine. Therefore, you will need to call -setjmp() and pass the png_jmpbuf(png_ptr). If you -write the file from different routines, you will need to update -the png_jmpbuf(png_ptr) every time you enter a new routine that will -call a png_*() function. See your documentation of setjmp/longjmp -for your compiler for more information on setjmp/longjmp. See -the discussion on libpng error handling in the Customizing Libpng -section below for more information on the libpng error handling. - - if (setjmp(png_jmpbuf(png_ptr))) - { - png_destroy_write_struct(&png_ptr, &info_ptr); - fclose(fp); - return (ERROR); - } - ... - return; - -If you would rather avoid the complexity of setjmp/longjmp issues, -you can compile libpng with PNG_SETJMP_NOT_SUPPORTED, in which case -errors will result in a call to PNG_ABORT() which defaults to abort(). - -Now you need to set up the output code. The default for libpng is to -use the C function fwrite(). If you use this, you will need to pass a -valid FILE * in the function png_init_io(). Be sure that the file is -opened in binary mode. Again, if you wish to handle writing data in -another way, see the discussion on libpng I/O handling in the Customizing -Libpng section below. - - png_init_io(png_ptr, fp); - -If you are embedding your PNG into a datastream such as MNG, and don't -want libpng to write the 8-byte signature, or if you have already -written the signature in your application, use - - png_set_sig_bytes(png_ptr, 8); - -to inform libpng that it should not write a signature. - -Write callbacks - -At this point, you can set up a callback function that will be -called after each row has been written, which you can use to control -a progress meter or the like. It's demonstrated in pngtest.c. -You must supply a function - - void write_row_callback(png_ptr, png_uint_32 row, - int pass); - { - /* put your code here */ - } - -(You can give it another name that you like instead of "write_row_callback") - -To inform libpng about your function, use - - png_set_write_status_fn(png_ptr, write_row_callback); - -You now have the option of modifying how the compression library will -run. The following functions are mainly for testing, but may be useful -in some cases, like if you need to write PNG files extremely fast and -are willing to give up some compression, or if you want to get the -maximum possible compression at the expense of slower writing. If you -have no special needs in this area, let the library do what it wants by -not calling this function at all, as it has been tuned to deliver a good -speed/compression ratio. The second parameter to png_set_filter() is -the filter method, for which the only valid values are 0 (as of the -July 1999 PNG specification, version 1.2) or 64 (if you are writing -a PNG datastream that is to be embedded in a MNG datastream). The third -parameter is a flag that indicates which filter type(s) are to be tested -for each scanline.

Within each of the "locations", -the chunks are sequenced according to their position in the -structure (that is, the value of "i", which is the order in which -the chunk was either read from the input file or defined with -png_set_unknown_chunks). - -A quick word about text and num_text. text is an array of png_text -structures. num_text is the number of valid structures in the array. -Each png_text structure holds a language code, a keyword, a text value, -and a compression type. - -The compression types have the same valid numbers as the compression -types of the image data. Currently, the only valid number is zero. -However, you can store text either compressed or uncompressed, unlike -images, which always have to be compressed. So if you don't want the -text compressed, set the compression type to PNG_TEXT_COMPRESSION_NONE. -Because tEXt and zTXt chunks don't have a language field, if you -specify PNG_TEXT_COMPRESSION_NONE or PNG_TEXT_COMPRESSION_zTXt -any language code or translated keyword will not be written out. - -Until text gets around 1000 bytes, it is not worth compressing it. -After the text has been written out to the file, the compression type -is set to PNG_TEXT_COMPRESSION_NONE_WR or PNG_TEXT_COMPRESSION_zTXt_WR, -so that it isn't written out again at the end (in case you are calling -png_write_end() with the same struct. - -The keywords that are given in the PNG Specification are: - - Title Short (one line) title or - caption for image - Author Name of image's creator - Description Description of image (possibly long) - Copyright Copyright notice - Creation Time Time of original image creation - (usually RFC 1123 format, see below) - Software Software used to create the image - Disclaimer Legal disclaimer - Warning Warning of nature of content - Source Device used to create the image - Comment Miscellaneous comment; conversion - from other image format - -The keyword-text pairs work like this. Keywords should be short -simple descriptions of what the comment is about. Some typical -keywords are found in the PNG specification, as is some recommendations -on keywords. You can repeat keywords in a file. You can even write -some text before the image and some after. For example, you may want -to put a description of the image before the image, but leave the -disclaimer until after, so viewers working over modem connections -don't have to wait for the disclaimer to go over the modem before -they start seeing the image. Finally, keywords should be full -words, not abbreviations. Keywords and text are in the ISO 8859-1 -(Latin-1) character set (a superset of regular ASCII) and can not -contain NUL characters, and should not contain control or other -unprintable characters. To make the comments widely readable, stick -with basic ASCII, and avoid machine specific character set extensions -like the IBM-PC character set. The keyword must be present, but -you can leave off the text string on non-compressed pairs. -Compressed pairs must have a text string, as only the text string -is compressed anyway, so the compression would be meaningless. - -PNG supports modification time via the png_time structure. Two -conversion routines are provided, png_convert_from_time_t() for -time_t and png_convert_from_struct_tm() for struct tm. The -time_t routine uses gmtime(). You don't have to use either of -these, but if you wish to fill in the png_time structure directly, -you should provide the time in universal time (GMT) if possible -instead of your local time. Note that the year number is the full -year (e.g. 1998, rather than 98 - PNG is year 2000 compliant!), and -that months start with 1. - -If you want to store the time of the original image creation, you should -use a plain tEXt chunk with the "Creation Time" keyword. This is -necessary because the "creation time" of a PNG image is somewhat vague, -depending on whether you mean the PNG file, the time the image was -created in a non-PNG format, a still photo from which the image was -scanned, or possibly the subject matter itself. In order to facilitate -machine-readable dates, it is recommended that the "Creation Time" -tEXt chunk use RFC 1123 format dates (e.g. "22 May 1997 18:07:10 GMT"), -although this isn't a requirement. Unlike the tIME chunk, the -"Creation Time" tEXt chunk is not expected to be automatically changed -by the software. To facilitate the use of RFC 1123 dates, a function -png_convert_to_rfc1123(png_timep) is provided to convert from PNG -time to an RFC 1123 format string. - -Writing unknown chunks - -You can use the png_set_unknown_chunks function to queue up chunks -for writing. You give it a chunk name, raw data, and a size; that's -all there is to it. The chunks will be written by the next following -png_write_info_before_PLTE, png_write_info, or png_write_end function. -Any chunks previously read into the info structure's unknown-chunk -list will also be written out in a sequence that satisfies the PNG -specification's ordering rules. - -The high-level write interface - -At this point there are two ways to proceed; through the high-level -write interface, or through a sequence of low-level write operations. -You can use the high-level interface if your image data is present -in the info structure. All defined output -transformations are permitted, enabled by the following masks. - - PNG_TRANSFORM_IDENTITY No transformation - PNG_TRANSFORM_PACKING Pack 1, 2 and 4-bit samples - PNG_TRANSFORM_PACKSWAP Change order of packed - pixels to LSB first - PNG_TRANSFORM_INVERT_MONO Invert monochrome images - PNG_TRANSFORM_SHIFT Normalize pixels to the - sBIT depth - PNG_TRANSFORM_BGR Flip RGB to BGR, RGBA - to BGRA - PNG_TRANSFORM_SWAP_ALPHA Flip RGBA to ARGB or GA - to AG - PNG_TRANSFORM_INVERT_ALPHA Change alpha from opacity - to transparency - PNG_TRANSFORM_SWAP_ENDIAN Byte-swap 16-bit samples - PNG_TRANSFORM_STRIP_FILLER Strip out filler bytes. - -If you have valid image data in the info structure (you can use -png_set_rows() to put image data in the info structure), simply do this: - - png_write_png(png_ptr, info_ptr, png_transforms, NULL) - -where png_transforms is an integer containing the bitwise OR of some set of -transformation flags. This call is equivalent to png_write_info(), -followed the set of transformations indicated by the transform mask, -then png_write_image(), and finally png_write_end(). - -(The final parameter of this call is not yet used. Someday it might point -to transformation parameters required by some future output transform.) - -You must use png_transforms and not call any png_set_transform() functions -when you use png_write_png(). - -The low-level write interface - -If you are going the low-level route instead, you are now ready to -write all the file information up to the actual image data. You do -this with a call to png_write_info(). - - png_write_info(png_ptr, info_ptr); - -Note that there is one transformation you may need to do before -png_write_info(). In PNG files, the alpha channel in an image is the -level of opacity. If your data is supplied as a level of -transparency, you can invert the alpha channel before you write it, so -that 0 is fully transparent and 255 (in 8-bit or paletted images) or -65535 (in 16-bit images) is fully opaque, with - - png_set_invert_alpha(png_ptr); - -This must appear before png_write_info() instead of later with the -other transformations because in the case of paletted images the tRNS -chunk data has to be inverted before the tRNS chunk is written. If -your image is not a paletted image, the tRNS data (which in such cases -represents a single color to be rendered as transparent) won't need to -be changed, and you can safely do this transformation after your -png_write_info() call. - -If you need to write a private chunk that you want to appear before -the PLTE chunk when PLTE is present, you can write the PNG info in -two steps, and insert code to write your own chunk between them: - - png_write_info_before_PLTE(png_ptr, info_ptr); - png_set_unknown_chunks(png_ptr, info_ptr, ...); - png_write_info(png_ptr, info_ptr); - -After you've written the file information, you can set up the library -to handle any special transformations of the image data. The various -ways to transform the data will be described in the order that they -should occur. This is important, as some of these change the color -type and/or bit depth of the data, and some others only work on -certain color types and bit depths. Even though each transformation -checks to see if it has data that it can do something with, you should -make sure to only enable a transformation if it will be valid for the -data. For example, don't swap red and blue on grayscale data. - -PNG files store RGB pixels packed into 3 or 6 bytes. This code tells -the library to strip input data that has 4 or 8 bytes per pixel down -to 3 or 6 bytes (or strip 2 or 4-byte grayscale+filler data to 1 or 2 -bytes per pixel). - - png_set_filler(png_ptr, 0, PNG_FILLER_BEFORE); - -where the 0 is unused, and the location is either PNG_FILLER_BEFORE or -PNG_FILLER_AFTER, depending upon whether the filler byte in the pixel -is stored XRGB or RGBX. - -PNG files pack pixels of bit depths 1, 2, and 4 into bytes as small as -they can, resulting in, for example, 8 pixels per byte for 1 bit files. -If the data is supplied at 1 pixel per byte, use this code, which will -correctly pack the pixels into a single byte: - - png_set_packing(png_ptr); - -PNG files reduce possible bit depths to 1, 2, 4, 8, and 16. If your -data is of another bit depth, you can write an sBIT chunk into the -file so that decoders can recover the original data if desired. - - /* Set the true bit depth of the image data */ - if (color_type & PNG_COLOR_MASK_COLOR) - { - sig_bit.red = true_bit_depth; - sig_bit.green = true_bit_depth; - sig_bit.blue = true_bit_depth; - } - else - { - sig_bit.gray = true_bit_depth; - } - if (color_type & PNG_COLOR_MASK_ALPHA) - { - sig_bit.alpha = true_bit_depth; - } - - png_set_sBIT(png_ptr, info_ptr, &sig_bit); - -If the data is stored in the row buffer in a bit depth other than -one supported by PNG (e.g. 3 bit data in the range 0-7 for a 4-bit PNG), -this will scale the values to appear to be the correct bit depth as -is required by PNG. - - png_set_shift(png_ptr, &sig_bit); - -PNG files store 16 bit pixels in network byte order (big-endian, -ie. most significant bits first). This code would be used if they are -supplied the other way (little-endian, i.e. least significant bits -first, the way PCs store them): - - if (bit_depth > 8) - png_set_swap(png_ptr); - -If you are using packed-pixel images (1, 2, or 4 bits/pixel), and you -need to change the order the pixels are packed into bytes, you can use: - - if (bit_depth < 8) - png_set_packswap(png_ptr); - -PNG files store 3 color pixels in red, green, blue order. This code -would be used if they are supplied as blue, green, red: - - png_set_bgr(png_ptr); - -PNG files describe monochrome as black being zero and white being -one. This code would be used if the pixels are supplied with this reversed -(black being one and white being zero): - - png_set_invert_mono(png_ptr); - -Finally, you can write your own transformation function if none of -the existing ones meets your needs. This is done by setting a callback -with - - png_set_write_user_transform_fn(png_ptr, - write_transform_fn); - -You must supply the function - - void write_transform_fn(png_ptr ptr, row_info_ptr - row_info, png_bytep data) - -See pngtest.c for a working example. Your function will be called -before any of the other transformations are processed. - -You can also set up a pointer to a user structure for use by your -callback function. - - png_set_user_transform_info(png_ptr, user_ptr, 0, 0); - -The user_channels and user_depth parameters of this function are ignored -when writing; you can set them to zero as shown. - -You can retrieve the pointer via the function png_get_user_transform_ptr(). -For example: - - voidp write_user_transform_ptr = - png_get_user_transform_ptr(png_ptr); - -It is possible to have libpng flush any pending output, either manually, -or automatically after a certain number of lines have been written. To -flush the output stream a single time call: - - png_write_flush(png_ptr); - -and to have libpng flush the output stream periodically after a certain -number of scanlines have been written, call: - - png_set_flush(png_ptr, nrows); - -Note that the distance between rows is from the last time png_write_flush() -was called, or the first row of the image if it has never been called. -So if you write 50 lines, and then png_set_flush 25, it will flush the -output on the next scanline, and every 25 lines thereafter, unless -png_write_flush() is called before 25 more lines have been written. -If nrows is too small (less than about 10 lines for a 640 pixel wide -RGB image) the image compression may decrease noticeably (although this -may be acceptable for real-time applications). Infrequent flushing will -only degrade the compression performance by a few percent over images -that do not use flushing. - -Writing the image data - -That's it for the transformations. Now you can write the image data. -The simplest way to do this is in one function call. If you have the -whole image in memory, you can just call png_write_image() and libpng -will write the image. You will need to pass in an array of pointers to -each row. This function automatically handles interlacing, so you don't -need to call png_set_interlace_handling() or call this function multiple -times, or any of that other stuff necessary with png_write_rows(). - - png_write_image(png_ptr, row_pointers); - -where row_pointers is: - - png_byte *row_pointers[height]; - -You can point to void or char or whatever you use for pixels. - -If you don't want to write the whole image at once, you can -use png_write_rows() instead. If the file is not interlaced, -this is simple: - - png_write_rows(png_ptr, row_pointers, - number_of_rows); - -row_pointers is the same as in the png_write_image() call. - -If you are just writing one row at a time, you can do this with -a single row_pointer instead of an array of row_pointers: - - png_bytep row_pointer = row; - - png_write_row(png_ptr, row_pointer); - -When the file is interlaced, things can get a good deal more -complicated. The only currently (as of the PNG Specification -version 1.2, dated July 1999) defined interlacing scheme for PNG files -is the "Adam7" interlace scheme, that breaks down an -image into seven smaller images of varying size. libpng will build -these images for you, or you can do them yourself. If you want to -build them yourself, see the PNG specification for details of which -pixels to write when. - -If you don't want libpng to handle the interlacing details, just -use png_set_interlace_handling() and call png_write_rows() the -correct number of times to write all seven sub-images. - -If you want libpng to build the sub-images, call this before you start -writing any rows: - - number_of_passes = - png_set_interlace_handling(png_ptr); - -This will return the number of passes needed. Currently, this -is seven, but may change if another interlace type is added. - -Then write the complete image number_of_passes times. - - png_write_rows(png_ptr, row_pointers, - number_of_rows); - -As some of these rows are not used, and thus return immediately, -you may want to read about interlacing in the PNG specification, -and only update the rows that are actually used. - -Finishing a sequential write - -After you are finished writing the image, you should finish writing -the file. If you are interested in writing comments or time, you should -pass an appropriately filled png_info pointer. If you are not interested, -you can pass NULL. - - png_write_end(png_ptr, info_ptr); - -When you are done, you can free all memory used by libpng like this: - - png_destroy_write_struct(&png_ptr, &info_ptr); - -It is also possible to individually free the info_ptr members that -point to libpng-allocated storage with the following function: - - png_free_data(png_ptr, info_ptr, mask, seq) - mask - identifies data to be freed, a mask - containing the bitwise OR of one or - more of - PNG_FREE_PLTE, PNG_FREE_TRNS, - PNG_FREE_HIST, PNG_FREE_ICCP, - PNG_FREE_PCAL, PNG_FREE_ROWS, - PNG_FREE_SCAL, PNG_FREE_SPLT, - PNG_FREE_TEXT, PNG_FREE_UNKN, - or simply PNG_FREE_ALL - seq - sequence number of item to be freed - (-1 for all items) - -This function may be safely called when the relevant storage has -already been freed, or has not yet been allocated, or was allocated -by the user and not by libpng, and will in those -cases do nothing. The "seq" parameter is ignored if only one item -of the selected data type, such as PLTE, is allowed. If "seq" is not --1, and multiple items are allowed for the data type identified in -the mask, such as text or sPLT, only the n'th item in the structure -is freed, where n is "seq". - -If you allocated data such as a palette that you passed -in to libpng with png_set_*, you must not free it until just before the call to -png_destroy_write_struct(). - -The default behavior is only to free data that was allocated internally -by libpng. This can be changed, so that libpng will not free the data, -or so that it will free data that was allocated by the user with png_malloc() -or png_zalloc() and passed in via a png_set_*() function, with - - png_data_freer(png_ptr, info_ptr, freer, mask) - mask - which data elements are affected - same choices as in png_free_data() - freer - one of - PNG_DESTROY_WILL_FREE_DATA - PNG_SET_WILL_FREE_DATA - PNG_USER_WILL_FREE_DATA - -For example, to transfer responsibility for some data from a read structure -to a write structure, you could use - - png_data_freer(read_ptr, read_info_ptr, - PNG_USER_WILL_FREE_DATA, - PNG_FREE_PLTE|PNG_FREE_tRNS|PNG_FREE_hIST) - png_data_freer(write_ptr, write_info_ptr, - PNG_DESTROY_WILL_FREE_DATA, - PNG_FREE_PLTE|PNG_FREE_tRNS|PNG_FREE_hIST) - -thereby briefly reassigning responsibility for freeing to the user but -immediately afterwards reassigning it once more to the write_destroy -function. Having done this, it would then be safe to destroy the read -structure and continue to use the PLTE, tRNS, and hIST data in the write -structure. - -This function only affects data that has already been allocated. -You can call this function before calling after the png_set_*() functions -to control whether the user or png_destroy_*() is supposed to free the data. -When the user assumes responsibility for libpng-allocated data, the -application must use -png_free() to free it, and when the user transfers responsibility to libpng -for data that the user has allocated, the user must have used png_malloc() -or png_zalloc() to allocate it. - -If you allocated text_ptr.text, text_ptr.lang, and text_ptr.translated_keyword -separately, do not transfer responsibility for freeing text_ptr to libpng, -because when libpng fills a png_text structure it combines these members with -the key member, and png_free_data() will free only text_ptr.key. Similarly, -if you transfer responsibility for free'ing text_ptr from libpng to your -application, your application must not separately free those members. -For a more compact example of writing a PNG image, see the file example.c. - -V. Modifying/Customizing libpng: - -There are two issues here. The first is changing how libpng does -standard things like memory allocation, input/output, and error handling. -The second deals with more complicated things like adding new chunks, -adding new transformations, and generally changing how libpng works. -Both of those are compile-time issues; that is, they are generally -determined at the time the code is written, and there is rarely a need -to provide the user with a means of changing them. - -Memory allocation, input/output, and error handling - -All of the memory allocation, input/output, and error handling in libpng -goes through callbacks that are user-settable. The default routines are -in pngmem.c, pngrio.c, pngwio.c, and pngerror.c, respectively. To change -these functions, call the appropriate png_set_*_fn() function. - -Memory allocation is done through the functions png_malloc() -and png_free(). These currently just call the standard C functions. If -your pointers can't access more then 64K at a time, you will want to set -MAXSEG_64K in zlib.h. Since it is unlikely that the method of handling -memory allocation on a platform will change between applications, these -functions must be modified in the library at compile time. If you prefer -to use a different method of allocating and freeing data, you can use -png_create_read_struct_2() or png_create_write_struct_2() to register -your own functions as described above. -These functions also provide a void pointer that can be retrieved via - - mem_ptr=png_get_mem_ptr(png_ptr); - -Your replacement memory functions must have prototypes as follows: - - png_voidp malloc_fn(png_structp png_ptr, - png_size_t size); - void free_fn(png_structp png_ptr, png_voidp ptr); - -Your malloc_fn() must return NULL in case of failure. The png_malloc() -function will normally call png_error() if it receives a NULL from the -system memory allocator or from your replacement malloc_fn(). - -Your free_fn() will never be called with a NULL ptr, since libpng's -png_free() checks for NULL before calling free_fn(). - -Input/Output in libpng is done through png_read() and png_write(), -which currently just call fread() and fwrite(). The FILE * is stored in -png_struct and is initialized via png_init_io(). If you wish to change -the method of I/O, the library supplies callbacks that you can set -through the function png_set_read_fn() and png_set_write_fn() at run -time, instead of calling the png_init_io() function. These functions -also provide a void pointer that can be retrieved via the function -png_get_io_ptr(). For example: - - png_set_read_fn(png_structp read_ptr, - voidp read_io_ptr, png_rw_ptr read_data_fn) - - png_set_write_fn(png_structp write_ptr, - voidp write_io_ptr, png_rw_ptr write_data_fn, - png_flush_ptr output_flush_fn); - - voidp read_io_ptr = png_get_io_ptr(read_ptr); - voidp write_io_ptr = png_get_io_ptr(write_ptr); - -The replacement I/O functions must have prototypes as follows: - - void user_read_data(png_structp png_ptr, - png_bytep data, png_size_t length); - void user_write_data(png_structp png_ptr, - png_bytep data, png_size_t length); - void user_flush_data(png_structp png_ptr); - -Supplying NULL for the read, write, or flush functions sets them back -to using the default C stream functions. It is an error to read from -a write stream, and vice versa. - -Error handling in libpng is done through png_error() and png_warning(). -Errors handled through png_error() are fatal, meaning that png_error() -should never return to its caller. Currently, this is handled via -setjmp() and longjmp() (unless you have compiled libpng with -PNG_SETJMP_NOT_SUPPORTED, in which case it is handled via PNG_ABORT()), -but you could change this to do things like exit() if you should wish. - -On non-fatal errors, png_warning() is called -to print a warning message, and then control returns to the calling code. -By default png_error() and png_warning() print a message on stderr via -fprintf() unless the library is compiled with PNG_NO_CONSOLE_IO defined -(because you don't want the messages) or PNG_NO_STDIO defined (because -fprintf() isn't available). If you wish to change the behavior of the error -functions, you will need to set up your own message callbacks. These -functions are normally supplied at the time that the png_struct is created. -It is also possible to redirect errors and warnings to your own replacement -functions after png_create_*_struct() has been called by calling: - - png_set_error_fn(png_structp png_ptr, - png_voidp error_ptr, png_error_ptr error_fn, - png_error_ptr warning_fn); - - png_voidp error_ptr = png_get_error_ptr(png_ptr); - -If NULL is supplied for either error_fn or warning_fn, then the libpng -default function will be used, calling fprintf() and/or longjmp() if a -problem is encountered. The replacement error functions should have -parameters as follows: - - void user_error_fn(png_structp png_ptr, - png_const_charp error_msg); - void user_warning_fn(png_structp png_ptr, - png_const_charp warning_msg); - -The motivation behind using setjmp() and longjmp() is the C++ throw and -catch exception handling methods. This makes the code much easier to write, -as there is no need to check every return code of every function call. -However, there are some uncertainties about the status of local variables -after a longjmp, so the user may want to be careful about doing anything after -setjmp returns non-zero besides returning itself. Consult your compiler -documentation for more details. For an alternative approach, you may wish -to use the "cexcept" facility (see http://cexcept.sourceforge.net). - -Custom chunks - -If you need to read or write custom chunks, you may need to get deeper -into the libpng code. The library now has mechanisms for storing -and writing chunks of unknown type; you can even declare callbacks -for custom chunks. However, this may not be good enough if the -library code itself needs to know about interactions between your -chunk and existing `intrinsic' chunks. - -If you need to write a new intrinsic chunk, first read the PNG -specification. Acquire a first level of -understanding of how it works. Pay particular attention to the -sections that describe chunk names, and look at how other chunks were -designed, so you can do things similarly. Second, check out the -sections of libpng that read and write chunks. Try to find a chunk -that is similar to yours and use it as a template. More details can -be found in the comments inside the code. It is best to handle unknown -chunks in a generic method, via callback functions, instead of by -modifying libpng functions. - -If you wish to write your own transformation for the data, look through -the part of the code that does the transformations, and check out some of -the simpler ones to get an idea of how they work. Try to find a similar -transformation to the one you want to add and copy off of it. More details -can be found in the comments inside the code itself. - -Configuring for 16 bit platforms - -You will want to look into zconf.h to tell zlib (and thus libpng) that -it cannot allocate more then 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. - -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. - -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 *. - -Configuring for gui/windowing platforms: - -You will need to write new error and warning functions that use the GUI -interface, as described previously, and set them to be the error and -warning functions at the time that png_create_*_struct() is called, -in order to have them available during the structure initialization. -They can be changed later via png_set_error_fn(). On some compilers, -you may also have to change the memory allocators (png_malloc, etc.). - -Configuring for compiler xxx: - -All includes for libpng are in pngconf.h. If you need to add/change/delete -an include, this is the place to do it. The includes that are not -needed outside libpng are protected by the PNG_INTERNAL definition, -which is only defined for those routines inside libpng itself. The -files in libpng proper only include png.h, which includes pngconf.h. - -Configuring zlib: - -There are special functions to configure the compression. Perhaps the -most useful one changes the compression level, which currently uses -input compression values in the range 0 - 9. The library normally -uses the default compression level (Z_DEFAULT_COMPRESSION = 6). Tests -have shown that for a large majority of images, compression values in -the range 3-6 compress nearly as well as higher levels, and do so much -faster. For online applications it may be desirable to have maximum speed -(Z_BEST_SPEED = 1). With versions of zlib after v0.99, you can also -specify no compression (Z_NO_COMPRESSION = 0), but this would create -files larger than just storing the raw bitmap. You can specify the -compression level by calling: - - png_set_compression_level(png_ptr, level); - -Another useful one is to reduce the memory level used by the library. -The memory level defaults to 8, but it can be lowered if you are -short on memory (running DOS, for example, where you only have 640K). -Note that the memory level does have an effect on compression; among -other things, lower levels will result in sections of incompressible -data being emitted in smaller stored blocks, with a correspondingly -larger relative overhead of up to 15% in the worst case. - - png_set_compression_mem_level(png_ptr, level); - -The other functions are for configuring zlib. They are not recommended -for normal use and may result in writing an invalid PNG file. See -zlib.h for more information on what these mean. - - png_set_compression_strategy(png_ptr, - strategy); - png_set_compression_window_bits(png_ptr, - window_bits); - png_set_compression_method(png_ptr, method); - png_set_compression_buffer_size(png_ptr, size); - -Controlling row filtering - -If you want to control whether libpng uses filtering or not, which -filters are used, and how it goes about picking row filters, you -can call one of these functions. The selection and configuration -of row filters can have a significant impact on the size and -encoding speed and a somewhat lesser impact on the decoding speed -of an image. Filtering is enabled by default for RGB and grayscale -images (with and without alpha), but not for paletted images nor -for any images with bit depths less than 8 bits/pixel. - -The 'method' parameter sets the main filtering method, which is -currently only '0' in the PNG 1.2 specification. The 'filters' -parameter sets which filter(s), if any, should be used for each -scanline. Possible values are PNG_ALL_FILTERS and PNG_NO_FILTERS -to turn filtering on and off, respectively. - -Individual filter types are PNG_FILTER_NONE, PNG_FILTER_SUB, -PNG_FILTER_UP, PNG_FILTER_AVG, PNG_FILTER_PAETH, which can be bitwise -ORed together with '|' to specify one or more filters to use. -These filters are described in more detail in the PNG specification. -If you intend to change the filter type during the course of writing -the image, you should start with flags set for all of the filters -you intend to use so that libpng can initialize its internal -structures appropriately for all of the filter types. (Note that this -means the first row must always be adaptively filtered, because libpng -currently does not allocate the filter buffers until png_write_row() -is called for the first time.) - - filters = PNG_FILTER_NONE | PNG_FILTER_SUB - PNG_FILTER_UP | PNG_FILTER_AVE | - PNG_FILTER_PAETH | PNG_ALL_FILTERS; - - png_set_filter(png_ptr, PNG_FILTER_TYPE_BASE, - filters); - The second parameter can also be - PNG_INTRAPIXEL_DIFFERENCING if you are - writing a PNG to be embedded in a MNG - datastream. This parameter must be the - same as the value of filter_method used - in png_set_IHDR(). - -It is also possible to influence how libpng chooses from among the -available filters. This is done in one or both of two ways - by -telling it how important it is to keep the same filter for successive -rows, and by telling it the relative computational costs of the filters. - - double weights[3] = {1.5, 1.3, 1.1}, - costs[PNG_FILTER_VALUE_LAST] = - {1.0, 1.3, 1.3, 1.5, 1.7}; - - png_set_filter_heuristics(png_ptr, - PNG_FILTER_HEURISTIC_WEIGHTED, 3, - weights, costs); - -The weights are multiplying factors that indicate to libpng that the -row filter should be the same for successive rows unless another row filter -is that many times better than the previous filter. In the above example, -if the previous 3 filters were SUB, SUB, NONE, the SUB filter could have a -"sum of absolute differences" 1.5 x 1.3 times higher than other filters -and still be chosen, while the NONE filter could have a sum 1.1 times -higher than other filters and still be chosen. Unspecified weights are -taken to be 1.0, and the specified weights should probably be declining -like those above in order to emphasize recent filters over older filters. - -The filter costs specify for each filter type a relative decoding cost -to be considered when selecting row filters. This means that filters -with higher costs are less likely to be chosen over filters with lower -costs, unless their "sum of absolute differences" is that much smaller. -The costs do not necessarily reflect the exact computational speeds of -the various filters, since this would unduly influence the final image -size. - -Note that the numbers above were invented purely for this example and -are given only to help explain the function usage. Little testing has -been done to find optimum values for either the costs or the weights. - -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_. - -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. - -Requesting debug printout - -The macro definition PNG_DEBUG can be used to request debugging -printout. Set it to an integer value in the range 0 to 3. Higher -numbers result in increasing amounts of debugging information. The -information is printed to the "stderr" file, unless another file -name is specified in the PNG_DEBUG_FILE macro definition. - -When PNG_DEBUG > 0, the following functions (macros) become available: - - png_debug(level, message) - png_debug1(level, message, p1) - png_debug2(level, message, p1, p2) - -in which "level" is compared to PNG_DEBUG to decide whether to print -the message, "message" is the formatted string to be printed, -and p1 and p2 are parameters that are to be embedded in the string -according to printf-style formatting directives. For example, - - png_debug1(2, "foo=%d\n", foo); - -is expanded to - - if(PNG_DEBUG > 2) - fprintf(PNG_DEBUG_FILE, "foo=%d\n", foo); - -When PNG_DEBUG is defined but is zero, the macros aren't defined, but you -can still use PNG_DEBUG to control your own debugging: - - #ifdef PNG_DEBUG - fprintf(stderr, ... - #endif - -When PNG_DEBUG = 1, the macros are defined, but only png_debug statements -having level = 0 will be printed. There aren't any such statements in -this version of libpng, but if you insert some they will be printed. - -VII. MNG support - -The MNG specification (available at http://www.libpng.org/pub/mng) allows -certain extensions to PNG for PNG images that are embedded in MNG datastreams. -Libpng can support some of these extensions. To enable them, use the -png_permit_mng_features() function: - - feature_set = png_permit_mng_features(png_ptr, mask) - mask is a png_uint_32 containing the bitwise OR of the - features you want to enable. These include - PNG_FLAG_MNG_EMPTY_PLTE - PNG_FLAG_MNG_FILTER_64 - PNG_ALL_MNG_FEATURES - feature_set is a png_uint_32 that is the bitwise AND of - your mask with the set of MNG features that is - supported by the version of libpng that you are using. - -It is an error to use this function when reading or writing a standalone -PNG file with the PNG 8-byte signature. The PNG datastream must be wrapped -in a MNG datastream. As a minimum, it must have the MNG 8-byte signature -and the MHDR and MEND chunks. Libpng does not provide support for these -or any other MNG chunks; your application must provide its own support for -them. You may wish to consider using libmng (available at -http://www.libmng.com) instead. - -VIII. Changes to Libpng from version 0.88 - -It should be noted that versions of libpng later than 0.96 are not -distributed by the original libpng author, Guy Schalnat, nor by -Andreas Dilger, who had taken over from Guy during 1996 and 1997, and -distributed versions 0.89 through 0.96, but rather by another member -of the original PNG Group, Glenn Randers-Pehrson. Guy and Andreas are -still alive and well, but they have moved on to other things. - -The old libpng functions png_read_init(), png_write_init(), -png_info_init(), png_read_destroy(), and png_write_destroy() have been -moved to PNG_INTERNAL in version 0.95 to discourage their use. These -functions will be removed from libpng version 2.0.0. - -The preferred method of creating and initializing the libpng structures is -via the png_create_read_struct(), png_create_write_struct(), and -png_create_info_struct() because they isolate the size of the structures -from the application, allow version error checking, and also allow the -use of custom error handling routines during the initialization, which -the old functions do not. The functions png_read_destroy() and -png_write_destroy() do not actually free the memory that libpng -allocated for these structs, but just reset the data structures, so they -can be used instead of png_destroy_read_struct() and -png_destroy_write_struct() if you feel there is too much system overhead -allocating and freeing the png_struct for each image read. - -Setting the error callbacks via png_set_message_fn() before -png_read_init() as was suggested in libpng-0.88 is no longer supported -because this caused applications that do not use custom error functions -to fail if the png_ptr was not initialized to zero. It is still possible -to set the error callbacks AFTER png_read_init(), or to change them with -png_set_error_fn(), which is essentially the same function, but with a new -name to force compilation errors with applications that try to use the old -method. - -Starting with version 1.0.7, you can find out which version of the library -you are using at run-time: - - png_uint_32 libpng_vn = png_access_version_number(); - -The number libpng_vn is constructed from the major version, minor -version with leading zero, and release number with leading zero, -(e.g., libpng_vn for version 1.0.7 is 10007). - -You can also check which version of png.h you used when compiling your -application: - - png_uint_32 application_vn = PNG_LIBPNG_VER; - -IX. Y2K Compliance in libpng - -December 18, 2008 - -Since the PNG Development group is an ad-hoc body, we can't make -an official declaration. - -This is your unofficial assurance that libpng from version 0.71 and -upward through 1.2.34 are Y2K compliant. It is my belief that earlier -versions were also Y2K compliant. - -Libpng only has three year fields. One is a 2-byte unsigned integer that -will hold years up to 65535. The other two hold the date in text -format, and will hold years up to 9999. - -The integer is - "png_uint_16 year" in png_time_struct. - -The strings are - "png_charp time_buffer" in png_struct and - "near_time_buffer", which is a local character string in png.c. - -There are seven time-related functions: - - png_convert_to_rfc_1123() in png.c - (formerly png_convert_to_rfc_1152() in error) - png_convert_from_struct_tm() in pngwrite.c, called - in pngwrite.c - png_convert_from_time_t() in pngwrite.c - png_get_tIME() in pngget.c - png_handle_tIME() in pngrutil.c, called in pngread.c - png_set_tIME() in pngset.c - png_write_tIME() in pngwutil.c, called in pngwrite.c - -All appear to handle dates properly in a Y2K environment. 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 applications using -libpng are not passing 4-digit years into the png_convert_to_rfc_1123() -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. The libpng documentation has always -stated that it works with 4-digit years, and the APIs have been -documented as such. - -The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned -integer to hold the year, and can hold years as large as 65535. - -zlib, upon which libpng depends, is also Y2K compliant. It contains -no date-related code. - - - Glenn Randers-Pehrson - libpng maintainer - PNG Development Group diff --git a/Build/source/libs/libpng/libpng-1.2.34/libpng.3 b/Build/source/libs/libpng/libpng-1.2.34/libpng.3 deleted file mode 100644 index fb5d65491ac..00000000000 --- a/Build/source/libs/libpng/libpng-1.2.34/libpng.3 +++ /dev/null @@ -1,4117 +0,0 @@ -.TH LIBPNG 3 "December 18, 2008" -.SH NAME -libpng \- Portable Network Graphics (PNG) Reference Library 1.2.34 -.SH SYNOPSIS -\fI\fB -

Wojcik - December 18, 1995 & January 20, 1996 - -.SH I. Introduction - -This file describes how to use and modify the PNG reference library -(known as libpng) for your own use. There are five sections to this -file: introduction, structures, reading, writing, and modification and -configuration notes for various special platforms. In addition to this -file, example.c is a good starting point for using the library, as -it is heavily commented and should include everything most people -will need. We assume that libpng is already installed; see the -INSTALL file for instructions on how to install libpng. - -For examples of libpng usage, see the files "example.c", "pngtest.c", -and the files in the "contrib" directory, all of which are included in the -libpng distribution. - -Libpng was written as a companion to the PNG specification, as a way -of reducing the amount of time and effort it takes to support the PNG -file format in application programs. - -The PNG specification (second edition), November 2003, is available as -a W3C Recommendation and as an ISO Standard (ISO/IEC 15948:2003 (E)) at -. It is technically equivalent -to the PNG specification (second edition) but has some additional material. - -The PNG-1.0 specification is available -as RFC 2083 and as a -W3C Recommendation . - -Some additional chunks are described in the special-purpose public chunks -documents at . - -Other information -about PNG, and the latest version of libpng, can be found at the PNG home -page, . - -Most users will not have to modify the library significantly; advanced -users may want to modify it more. All attempts were made to make it as -complete as possible, while keeping the code easy to understand. -Currently, this library only supports C. Support for other languages -is being considered. - -Libpng has been designed to handle multiple sessions at one time, -to be easily modifiable, to be portable to the vast majority of -machines (ANSI, K&R, 16-, 32-, and 64-bit) available, and to be easy -to use. The ultimate goal of libpng is to promote the acceptance of -the PNG file format in whatever way possible. While there is still -work to be done (see the TODO file), libpng should cover the -majority of the needs of its users. - -Libpng uses zlib for its compression and decompression of PNG files. -Further information about zlib, and the latest version of zlib, can -be found at the zlib home page, . -The zlib compression utility is a general purpose utility that is -useful for more than PNG files, and can be used without libpng. -See the documentation delivered with zlib for more details. -You can usually find the source files for the zlib utility wherever you -find the libpng source files. - -Libpng is thread safe, provided the threads are using different -instances of the structures. Each thread should have its own -png_struct and png_info instances, and thus its own image. -Libpng does not protect itself against two threads using the -same instance of a structure. - -.SH II. Structures - -There are two main structures that are important to libpng, png_struct -and png_info. The first, png_struct, is an internal structure that -will not, for the most part, be used by a user except as the first -variable passed to every libpng function call. - -The png_info structure is designed to provide information about the -PNG file. At one time, the fields of png_info were intended to be -directly accessible to the user. However, this tended to cause problems -with applications using dynamically loaded libraries, and as a result -a set of interface functions for png_info (the png_get_*() and png_set_*() -functions) was developed. The fields of png_info are still available for -older applications, but it is suggested that applications use the new -interfaces if at all possible. - -Applications that do make direct access to the members of png_struct (except -for png_ptr->jmpbuf) must be recompiled whenever the library is updated, -and applications that make direct access to the members of png_info must -be recompiled if they were compiled or loaded with libpng version 1.0.6, -in which the members were in a different order. In version 1.0.7, the -members of the png_info structure reverted to the old order, as they were -in versions 0.97c through 1.0.5. Starting with version 2.0.0, both -structures are going to be hidden, and the contents of the structures will -only be accessible through the png_get/png_set functions. - -The png.h header file is an invaluable reference for programming with libpng. -And while I'm on the topic, make sure you include the libpng header file: - -#include - -.SH III. Reading - -We'll now walk you through the possible functions to call when reading -in a PNG file sequentially, briefly explaining the syntax and purpose -of each one. See example.c and png.h for more detail. While -progressive reading is covered in the next section, you will still -need some of the functions discussed in this section to read a PNG -file. - -.SS Setup - -You will want to do the I/O initialization(*) before you get into libpng, -so if it doesn't work, you don't have much to undo. Of course, you -will also want to insure that you are, in fact, dealing with a PNG -file. Libpng provides a simple check to see if a file is a PNG file. -To use it, pass in the first 1 to 8 bytes of the file to the function -png_sig_cmp(), and it will return 0 if the bytes match the corresponding -bytes of the PNG signature, or nonzero otherwise. Of course, the more bytes -you pass in, the greater the accuracy of the prediction. - -If you are intending to keep the file pointer open for use in libpng, -you must ensure you don't read more than 8 bytes from the beginning -of the file, and you also have to make a call to png_set_sig_bytes_read() -with the number of bytes you read from the beginning. Libpng will -then only check the bytes (if any) that your program didn't read. - -(*): If you are not using the standard I/O functions, you will need -to replace them with custom functions. See the discussion under -Customizing libpng. - - - FILE *fp = fopen(file_name, "rb"); - if (!fp) - { - return (ERROR); - } - fread(header, 1, number, fp); - is_png = !png_sig_cmp(header, 0, number); - if (!is_png) - { - return (NOT_PNG); - } - - -Next, png_struct and png_info need to be allocated and initialized. In -order to ensure that the size of these structures is correct even with a -dynamically linked libpng, there are functions to initialize and -allocate the structures. We also pass the library version, optional -pointers to error handling functions, and a pointer to a data struct for -use by the error functions, if necessary (the pointer and functions can -be NULL if the default error handlers are to be used). See the section -on Changes to Libpng below regarding the old initialization functions. -The structure allocation functions quietly return NULL if they fail to -create the structure, so your application should check for that. - - png_structp png_ptr = png_create_read_struct - (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr, - user_error_fn, user_warning_fn); - if (!png_ptr) - return (ERROR); - - png_infop info_ptr = png_create_info_struct(png_ptr); - if (!info_ptr) - { - png_destroy_read_struct(&png_ptr, - (png_infopp)NULL, (png_infopp)NULL); - return (ERROR); - } - - png_infop end_info = png_create_info_struct(png_ptr); - if (!end_info) - { - png_destroy_read_struct(&png_ptr, &info_ptr, - (png_infopp)NULL); - return (ERROR); - } - -If you want to use your own memory allocation routines, -define PNG_USER_MEM_SUPPORTED and use -png_create_read_struct_2() instead of png_create_read_struct(): - - png_structp png_ptr = png_create_read_struct_2 - (PNG_LIBPNG_VER_STRING, (png_voidp)user_error_ptr, - user_error_fn, user_warning_fn, (png_voidp) - user_mem_ptr, user_malloc_fn, user_free_fn); - -The error handling routines passed to png_create_read_struct() -and the memory alloc/free routines passed to png_create_struct_2() -are only necessary if you are not using the libpng supplied error -handling and memory alloc/free functions. - -When libpng encounters an error, it expects to longjmp back -to your routine. Therefore, you will need to call setjmp and pass -your png_jmpbuf(png_ptr). If you read the file from different -routines, you will need to update the jmpbuf field every time you enter -a new routine that will call a png_*() function. - -See your documentation of setjmp/longjmp for your compiler for more -information on setjmp/longjmp. See the discussion on libpng error -handling in the Customizing Libpng section below for more information -on the libpng error handling.

It is possible to have the same keyword any number of times. -The text_ptr is an array of png_text structures, each holding a -pointer to a language string, a pointer to a keyword and a pointer to -a text string. The text string, language code, and translated -keyword may be empty or NULL pointers. The keyword/text -pairs are put into the array in the order that they are received. -However, some or all of the text chunks may be after the image, so, to -make sure you have read all the text chunks, don't mess with these -until after you read the stuff after the image. This will be -mentioned again below in the discussion that goes with png_read_end(). - -.SS Input transformations - -After you've read the header information, you can set up the library -to handle any special transformations of the image data. The various -ways to transform the data will be described in the order that they -should occur. This is important, as some of these change the color -type and/or bit depth of the data, and some others only work on -certain color types and bit depths. Even though each transformation -checks to see if it has data that it can do something with, you should -make sure to only enable a transformation if it will be valid for the -data. For example, don't swap red and blue on grayscale data. - -The colors used for the background and transparency values should be -supplied in the same format/depth as the current image data. They -are stored in the same format/depth as the image data in a bKGD or tRNS -chunk, so this is what libpng expects for this data. The colors are -transformed to keep in sync with the image data when an application -calls the png_read_update_info() routine (see below). - -Data will be decoded into the supplied row buffers packed into bytes -unless the library has been told to transform it into another format. -For example, 4 bit/pixel paletted or grayscale data will be returned -2 pixels/byte with the leftmost pixel in the high-order bits of the -byte, unless png_set_packing() is called. 8-bit RGB data will be stored -in RGB RGB RGB format unless png_set_filler() or png_set_add_alpha() -is called to insert filler bytes, either before or after each RGB triplet. -16-bit RGB data will be returned RRGGBB RRGGBB, with the most significant -byte of the color value first, unless png_set_strip_16() is called to -transform it to regular RGB RGB triplets, or png_set_filler() or -png_set_add alpha() is called to insert filler bytes, either before or -after each RRGGBB triplet. Similarly, 8-bit or 16-bit grayscale data can -be modified with -png_set_filler(), png_set_add_alpha(), or png_set_strip_16(). - -The following code transforms grayscale images of less than 8 to 8 bits, -changes paletted images to RGB, and adds a full alpha channel if there is -transparency information in a tRNS chunk.

It expands the sample depth without changing tRNS to alpha. -At the same time, png_set_gray_1_2_4_to_8() was deprecated, and it -will be removed from a future version. - - -PNG can have files with 16 bits per channel. If you only can handle -8 bits per channel, this will strip the pixels down to 8 bit. - - if (bit_depth == 16) - png_set_strip_16(png_ptr); - -If, for some reason, you don't need the alpha channel on an image, -and you want to remove it rather than combining it with the background -(but the image author certainly had in mind that you *would* combine -it with the background, so that's what you should probably do): - - if (color_type & PNG_COLOR_MASK_ALPHA) - png_set_strip_alpha(png_ptr); - -In PNG files, the alpha channel in an image -is the level of opacity.

If you -are allocating one large chunk, you will need to build an -array of pointers to each row, as it will be needed for some -of the functions below. - -.SS Reading image data - -After you've allocated memory, you can read the image data. -The simplest way to do this is in one function call. If you are -allocating enough memory to hold the whole image, you can just -call png_read_image() and libpng will read in all the image data -and put it in the memory area supplied. You will need to pass in -an array of pointers to each row. - -This function automatically handles interlacing, so you don't need -to call png_set_interlace_handling() or call this function multiple -times, or any of that other stuff necessary with png_read_rows(). - - png_read_image(png_ptr, row_pointers); - -where row_pointers is: - - png_bytep row_pointers[height]; - -You can point to void or char or whatever you use for pixels. - -If you don't want to read in the whole image at once, you can -use png_read_rows() instead. If there is no interlacing (check -interlace_type == PNG_INTERLACE_NONE), this is simple: - - png_read_rows(png_ptr, row_pointers, NULL, - number_of_rows); - -where row_pointers is the same as in the png_read_image() call. - -If you are doing this just one row at a time, you can do this with -a single row_pointer instead of an array of row_pointers: - - png_bytep row_pointer = row; - png_read_row(png_ptr, row_pointer, NULL); - -If the file is interlaced (interlace_type != 0 in the IHDR chunk), things -get somewhat harder. The only current (PNG Specification version 1.2) -interlacing type for PNG is (interlace_type == PNG_INTERLACE_ADAM7) -is a somewhat complicated 2D interlace scheme, known as Adam7, that -breaks down an image into seven smaller images of varying size, based -on an 8x8 grid. - -libpng can fill out those images or it can give them to you "as is". -If you want them filled out, there are two ways to do that. The one -mentioned in the PNG specification is to expand each pixel to cover -those pixels that have not been read yet (the "rectangle" method). -This results in a blocky image for the first pass, which gradually -smooths out as more pixels are read. The other method is the "sparkle" -method, where pixels are drawn only in their final locations, with the -rest of the image remaining whatever colors they were initialized to -before the start of the read. The first method usually looks better, -but tends to be slower, as there are more pixels to put in the rows. - -If you don't want libpng to handle the interlacing details, just call -png_read_rows() seven times to read in all seven images. Each of the -images is a valid image by itself, or they can all be combined on an -8x8 grid to form a single image (although if you intend to combine them -you would be far better off using the libpng interlace handling). - -The first pass will return an image 1/8 as wide as the entire image -(every 8th column starting in column 0) and 1/8 as high as the original -(every 8th row starting in row 0), the second will be 1/8 as wide -(starting in column 4) and 1/8 as high (also starting in row 0). The -third pass will be 1/4 as wide (every 4th pixel starting in column 0) and -1/8 as high (every 8th row starting in row 4), and the fourth pass will -be 1/4 as wide and 1/4 as high (every 4th column starting in column 2, -and every 4th row starting in row 0). The fifth pass will return an -image 1/2 as wide, and 1/4 as high (starting at column 0 and row 2), -while the sixth pass will be 1/2 as wide and 1/2 as high as the original -(starting in column 1 and row 0). The seventh and final pass will be as -wide as the original, and 1/2 as high, containing all of the odd -numbered scanlines. Phew! - -If you want libpng to expand the images, call this before calling -png_start_read_image() or png_read_update_info(): - - if (interlace_type == PNG_INTERLACE_ADAM7) - number_of_passes - = png_set_interlace_handling(png_ptr); - -This will return the number of passes needed. Currently, this -is seven, but may change if another interlace type is added. -This function can be called even if the file is not interlaced, -where it will return one pass. - -If you are not going to display the image after each pass, but are -going to wait until the entire image is read in, use the sparkle -effect. This effect is faster and the end result of either method -is exactly the same. If you are planning on displaying the image -after each pass, the "rectangle" effect is generally considered the -better looking one. - -If you only want the "sparkle" effect, just call png_read_rows() as -normal, with the third parameter NULL. Make sure you make pass over -the image number_of_passes times, and you don't change the data in the -rows between calls. You can change the locations of the data, just -not the data. Each pass only writes the pixels appropriate for that -pass, and assumes the data from previous passes is still valid. - - png_read_rows(png_ptr, row_pointers, NULL, - number_of_rows); - -If you only want the first effect (the rectangles), do the same as -before except pass the row buffer in the third parameter, and leave -the second parameter NULL. - - png_read_rows(png_ptr, NULL, row_pointers, - number_of_rows); - -.SS Finishing a sequential read - -After you are finished reading the image through the -low-level interface, you can finish reading the file. If you are -interested in comments or time, which may be stored either before or -after the image data, you should pass the separate png_info struct if -you want to keep the comments from before and after the image -separate. If you are not interested, you can pass NULL. - - png_read_end(png_ptr, end_info); - -When you are done, you can free all memory allocated by libpng like this: - - png_destroy_read_struct(&png_ptr, &info_ptr, - &end_info); - -It is also possible to individually free the info_ptr members that -point to libpng-allocated storage with the following function: - - png_free_data(png_ptr, info_ptr, mask, seq) - mask - identifies data to be freed, a mask - containing the bitwise OR of one or - more of - PNG_FREE_PLTE, PNG_FREE_TRNS, - PNG_FREE_HIST, PNG_FREE_ICCP, - PNG_FREE_PCAL, PNG_FREE_ROWS, - PNG_FREE_SCAL, PNG_FREE_SPLT, - PNG_FREE_TEXT, PNG_FREE_UNKN, - or simply PNG_FREE_ALL - seq - sequence number of item to be freed - (-1 for all items) - -This function may be safely called when the relevant storage has -already been freed, or has not yet been allocated, or was allocated -by the user and not by libpng, and will in those -cases do nothing.

If "seq" is not --1, and multiple items are allowed for the data type identified in -the mask, such as text or sPLT, only the n'th item in the structure -is freed, where n is "seq". - -The default behavior is only to free data that was allocated internally -by libpng. This can be changed, so that libpng will not free the data, -or so that it will free data that was allocated by the user with png_malloc() -or png_zalloc() and passed in via a png_set_*() function, with - - png_data_freer(png_ptr, info_ptr, freer, mask) - mask - which data elements are affected - same choices as in png_free_data() - freer - one of - PNG_DESTROY_WILL_FREE_DATA - PNG_SET_WILL_FREE_DATA - PNG_USER_WILL_FREE_DATA - -This function only affects data that has already been allocated. -You can call this function after reading the PNG data but before calling -any png_set_*() functions, to control whether the user or the png_set_*() -function is responsible for freeing any existing data that might be present, -and again after the png_set_*() functions to control whether the user -or png_destroy_*() is supposed to free the data. When the user assumes -responsibility for libpng-allocated data, the application must use -png_free() to free it, and when the user transfers responsibility to libpng -for data that the user has allocated, the user must have used png_malloc() -or png_zalloc() to allocate it. - -If you allocated your row_pointers in a single block, as suggested above in -the description of the high level read interface, you must not transfer -responsibility for freeing it to the png_set_rows or png_read_destroy function, -because they would also try to free the individual row_pointers[i]. - -If you allocated text_ptr.text, text_ptr.lang, and text_ptr.translated_keyword -separately, do not transfer responsibility for freeing text_ptr to libpng, -because when libpng fills a png_text structure it combines these members with -the key member, and png_free_data() will free only text_ptr.key.

See also significant - bits (sBIT) below). - color_type - describes which color/alpha - channels are present. - PNG_COLOR_TYPE_GRAY - (bit depths 1, 2, 4, 8, 16) - PNG_COLOR_TYPE_GRAY_ALPHA - (bit depths 8, 16) - PNG_COLOR_TYPE_PALETTE - (bit depths 1, 2, 4, 8) - PNG_COLOR_TYPE_RGB - (bit_depths 8, 16) - PNG_COLOR_TYPE_RGB_ALPHA - (bit_depths 8, 16) - - PNG_COLOR_MASK_PALETTE - PNG_COLOR_MASK_COLOR - PNG_COLOR_MASK_ALPHA - - interlace_type - PNG_INTERLACE_NONE or - PNG_INTERLACE_ADAM7 - compression_type - (must be - PNG_COMPRESSION_TYPE_DEFAULT) - filter_method - (must be PNG_FILTER_TYPE_DEFAULT - or, if you are writing a PNG to - be embedded in a MNG datastream, - can also be - PNG_INTRAPIXEL_DIFFERENCING) - -If you call png_set_IHDR(), the call must appear before any of the -other png_set_*() functions, which might require access to some of -the IHDR settings. The remaining png_set_*() functions can be called -in any order. - - png_set_PLTE(png_ptr, info_ptr, palette, - num_palette); - palette - the palette for the file - (array of png_color) - num_palette - number of entries in the palette - - png_set_gAMA(png_ptr, info_ptr, gamma); - gamma - the gamma the image was created - at (PNG_INFO_gAMA) - - png_set_sRGB(png_ptr, info_ptr, srgb_intent); - srgb_intent - the rendering intent - (PNG_INFO_sRGB) The presence of - the sRGB chunk means that the pixel - data is in the sRGB color space. - This chunk also implies specific - values of gAMA and cHRM. Rendering - intent is the CSS-1 property that - has been defined by the International - Color Consortium - (http://www.color.org). - It can be one of - PNG_sRGB_INTENT_SATURATION, - PNG_sRGB_INTENT_PERCEPTUAL, - PNG_sRGB_INTENT_ABSOLUTE, or - PNG_sRGB_INTENT_RELATIVE. - - - png_set_sRGB_gAMA_and_cHRM(png_ptr, info_ptr, - srgb_intent); - srgb_intent - the rendering intent - (PNG_INFO_sRGB) The presence of the - sRGB chunk means that the pixel - data is in the sRGB color space. - This function also causes gAMA and - cHRM chunks with the specific values - that are consistent with sRGB to be - written. - - png_set_iCCP(png_ptr, info_ptr, name, compression_type, - profile, proflen); - name - The profile name. - compression - The compression type; always - PNG_COMPRESSION_TYPE_BASE for PNG 1.0. - You may give NULL to this argument to - ignore it. - profile - International Color Consortium color - profile data. May contain NULs. - proflen - length of profile data in bytes. - - png_set_sBIT(png_ptr, info_ptr, sig_bit); - sig_bit - the number of significant bits for - (PNG_INFO_sBIT) each of the gray, red, - green, and blue channels, whichever are - appropriate for the given color type - (png_color_16) - - png_set_tRNS(png_ptr, info_ptr, trans, num_trans, - trans_values); - trans - array of transparent entries for - palette (PNG_INFO_tRNS) - trans_values - graylevel or color sample values of - the single transparent color for - non-paletted images (PNG_INFO_tRNS) - num_trans - number of transparent entries - (PNG_INFO_tRNS) - - png_set_hIST(png_ptr, info_ptr, hist); - (PNG_INFO_hIST) - hist - histogram of palette (array of - png_uint_16) - - png_set_tIME(png_ptr, info_ptr, mod_time); - mod_time - time image was last modified - (PNG_VALID_tIME) - - png_set_bKGD(png_ptr, info_ptr, background); - background - background color (PNG_VALID_bKGD) - - png_set_text(png_ptr, info_ptr, text_ptr, num_text); - text_ptr - array of png_text holding image - comments - text_ptr[i].compression - type of compression used - on "text" PNG_TEXT_COMPRESSION_NONE - PNG_TEXT_COMPRESSION_zTXt - PNG_ITXT_COMPRESSION_NONE - PNG_ITXT_COMPRESSION_zTXt - text_ptr[i].key - keyword for comment.

Within each of the "locations", -the chunks are sequenced according to their position in the -structure (that is, the value of "i", which is the order in which -the chunk was either read from the input file or defined with -png_set_unknown_chunks). - -A quick word about text and num_text. text is an array of png_text -structures. num_text is the number of valid structures in the array. -Each png_text structure holds a language code, a keyword, a text value, -and a compression type. - -The compression types have the same valid numbers as the compression -types of the image data. Currently, the only valid number is zero. -However, you can store text either compressed or uncompressed, unlike -images, which always have to be compressed. So if you don't want the -text compressed, set the compression type to PNG_TEXT_COMPRESSION_NONE. -Because tEXt and zTXt chunks don't have a language field, if you -specify PNG_TEXT_COMPRESSION_NONE or PNG_TEXT_COMPRESSION_zTXt -any language code or translated keyword will not be written out. - -Until text gets around 1000 bytes, it is not worth compressing it. -After the text has been written out to the file, the compression type -is set to PNG_TEXT_COMPRESSION_NONE_WR or PNG_TEXT_COMPRESSION_zTXt_WR, -so that it isn't written out again at the end (in case you are calling -png_write_end() with the same struct. - -The keywords that are given in the PNG Specification are: - - Title Short (one line) title or - caption for image - Author Name of image's creator - Description Description of image (possibly long) - Copyright Copyright notice - Creation Time Time of original image creation - (usually RFC 1123 format, see below) - Software Software used to create the image - Disclaimer Legal disclaimer - Warning Warning of nature of content - Source Device used to create the image - Comment Miscellaneous comment; conversion - from other image format - -The keyword-text pairs work like this. Keywords should be short -simple descriptions of what the comment is about. Some typical -keywords are found in the PNG specification, as is some recommendations -on keywords. You can repeat keywords in a file. You can even write -some text before the image and some after. For example, you may want -to put a description of the image before the image, but leave the -disclaimer until after, so viewers working over modem connections -don't have to wait for the disclaimer to go over the modem before -they start seeing the image. Finally, keywords should be full -words, not abbreviations. Keywords and text are in the ISO 8859-1 -(Latin-1) character set (a superset of regular ASCII) and can not -contain NUL characters, and should not contain control or other -unprintable characters. To make the comments widely readable, stick -with basic ASCII, and avoid machine specific character set extensions -like the IBM-PC character set. The keyword must be present, but -you can leave off the text string on non-compressed pairs. -Compressed pairs must have a text string, as only the text string -is compressed anyway, so the compression would be meaningless. - -PNG supports modification time via the png_time structure. Two -conversion routines are provided, png_convert_from_time_t() for -time_t and png_convert_from_struct_tm() for struct tm. The -time_t routine uses gmtime(). You don't have to use either of -these, but if you wish to fill in the png_time structure directly, -you should provide the time in universal time (GMT) if possible -instead of your local time. Note that the year number is the full -year (e.g. 1998, rather than 98 - PNG is year 2000 compliant!), and -that months start with 1. - -If you want to store the time of the original image creation, you should -use a plain tEXt chunk with the "Creation Time" keyword. This is -necessary because the "creation time" of a PNG image is somewhat vague, -depending on whether you mean the PNG file, the time the image was -created in a non-PNG format, a still photo from which the image was -scanned, or possibly the subject matter itself. In order to facilitate -machine-readable dates, it is recommended that the "Creation Time" -tEXt chunk use RFC 1123 format dates (e.g. "22 May 1997 18:07:10 GMT"), -although this isn't a requirement. Unlike the tIME chunk, the -"Creation Time" tEXt chunk is not expected to be automatically changed -by the software. To facilitate the use of RFC 1123 dates, a function -png_convert_to_rfc1123(png_timep) is provided to convert from PNG -time to an RFC 1123 format string. - -.SS Writing unknown chunks - -You can use the png_set_unknown_chunks function to queue up chunks -for writing. You give it a chunk name, raw data, and a size; that's -all there is to it. The chunks will be written by the next following -png_write_info_before_PLTE, png_write_info, or png_write_end function. -Any chunks previously read into the info structure's unknown-chunk -list will also be written out in a sequence that satisfies the PNG -specification's ordering rules. - -.SS The high-level write interface - -At this point there are two ways to proceed; through the high-level -write interface, or through a sequence of low-level write operations. -You can use the high-level interface if your image data is present -in the info structure. All defined output -transformations are permitted, enabled by the following masks. - - PNG_TRANSFORM_IDENTITY No transformation - PNG_TRANSFORM_PACKING Pack 1, 2 and 4-bit samples - PNG_TRANSFORM_PACKSWAP Change order of packed - pixels to LSB first - PNG_TRANSFORM_INVERT_MONO Invert monochrome images - PNG_TRANSFORM_SHIFT Normalize pixels to the - sBIT depth - PNG_TRANSFORM_BGR Flip RGB to BGR, RGBA - to BGRA - PNG_TRANSFORM_SWAP_ALPHA Flip RGBA to ARGB or GA - to AG - PNG_TRANSFORM_INVERT_ALPHA Change alpha from opacity - to transparency - PNG_TRANSFORM_SWAP_ENDIAN Byte-swap 16-bit samples - PNG_TRANSFORM_STRIP_FILLER Strip out filler bytes. - -If you have valid image data in the info structure (you can use -png_set_rows() to put image data in the info structure), simply do this: - - png_write_png(png_ptr, info_ptr, png_transforms, NULL) - -where png_transforms is an integer containing the bitwise OR of some set of -transformation flags. This call is equivalent to png_write_info(), -followed the set of transformations indicated by the transform mask, -then png_write_image(), and finally png_write_end(). - -(The final parameter of this call is not yet used. Someday it might point -to transformation parameters required by some future output transform.) - -You must use png_transforms and not call any png_set_transform() functions -when you use png_write_png(). - -.SS The low-level write interface - -If you are going the low-level route instead, you are now ready to -write all the file information up to the actual image data. You do -this with a call to png_write_info(). - - png_write_info(png_ptr, info_ptr); - -Note that there is one transformation you may need to do before -png_write_info(). In PNG files, the alpha channel in an image is the -level of opacity. If your data is supplied as a level of -transparency, you can invert the alpha channel before you write it, so -that 0 is fully transparent and 255 (in 8-bit or paletted images) or -65535 (in 16-bit images) is fully opaque, with - - png_set_invert_alpha(png_ptr); - -This must appear before png_write_info() instead of later with the -other transformations because in the case of paletted images the tRNS -chunk data has to be inverted before the tRNS chunk is written. If -your image is not a paletted image, the tRNS data (which in such cases -represents a single color to be rendered as transparent) won't need to -be changed, and you can safely do this transformation after your -png_write_info() call. - -If you need to write a private chunk that you want to appear before -the PLTE chunk when PLTE is present, you can write the PNG info in -two steps, and insert code to write your own chunk between them: - - png_write_info_before_PLTE(png_ptr, info_ptr); - png_set_unknown_chunks(png_ptr, info_ptr, ...); - png_write_info(png_ptr, info_ptr); - -After you've written the file information, you can set up the library -to handle any special transformations of the image data. The various -ways to transform the data will be described in the order that they -should occur. This is important, as some of these change the color -type and/or bit depth of the data, and some others only work on -certain color types and bit depths. Even though each transformation -checks to see if it has data that it can do something with, you should -make sure to only enable a transformation if it will be valid for the -data. For example, don't swap red and blue on grayscale data. - -PNG files store RGB pixels packed into 3 or 6 bytes. This code tells -the library to strip input data that has 4 or 8 bytes per pixel down -to 3 or 6 bytes (or strip 2 or 4-byte grayscale+filler data to 1 or 2 -bytes per pixel). - - png_set_filler(png_ptr, 0, PNG_FILLER_BEFORE); - -where the 0 is unused, and the location is either PNG_FILLER_BEFORE or -PNG_FILLER_AFTER, depending upon whether the filler byte in the pixel -is stored XRGB or RGBX. - -PNG files pack pixels of bit depths 1, 2, and 4 into bytes as small as -they can, resulting in, for example, 8 pixels per byte for 1 bit files. -If the data is supplied at 1 pixel per byte, use this code, which will -correctly pack the pixels into a single byte: - - png_set_packing(png_ptr); - -PNG files reduce possible bit depths to 1, 2, 4, 8, and 16. If your -data is of another bit depth, you can write an sBIT chunk into the -file so that decoders can recover the original data if desired. - - /* Set the true bit depth of the image data */ - if (color_type & PNG_COLOR_MASK_COLOR) - { - sig_bit.red = true_bit_depth; - sig_bit.green = true_bit_depth; - sig_bit.blue = true_bit_depth; - } - else - { - sig_bit.gray = true_bit_depth; - } - if (color_type & PNG_COLOR_MASK_ALPHA) - { - sig_bit.alpha = true_bit_depth; - } - - png_set_sBIT(png_ptr, info_ptr, &sig_bit); - -If the data is stored in the row buffer in a bit depth other than -one supported by PNG (e.g. 3 bit data in the range 0-7 for a 4-bit PNG), -this will scale the values to appear to be the correct bit depth as -is required by PNG. - - png_set_shift(png_ptr, &sig_bit); - -PNG files store 16 bit pixels in network byte order (big-endian, -ie. most significant bits first). This code would be used if they are -supplied the other way (little-endian, i.e. least significant bits -first, the way PCs store them): - - if (bit_depth > 8) - png_set_swap(png_ptr); - -If you are using packed-pixel images (1, 2, or 4 bits/pixel), and you -need to change the order the pixels are packed into bytes, you can use: - - if (bit_depth < 8) - png_set_packswap(png_ptr); - -PNG files store 3 color pixels in red, green, blue order. This code -would be used if they are supplied as blue, green, red: - - png_set_bgr(png_ptr); - -PNG files describe monochrome as black being zero and white being -one. This code would be used if the pixels are supplied with this reversed -(black being one and white being zero): - - png_set_invert_mono(png_ptr); - -Finally, you can write your own transformation function if none of -the existing ones meets your needs. This is done by setting a callback -with - - png_set_write_user_transform_fn(png_ptr, - write_transform_fn); - -You must supply the function - - void write_transform_fn(png_ptr ptr, row_info_ptr - row_info, png_bytep data) - -See pngtest.c for a working example. Your function will be called -before any of the other transformations are processed. - -You can also set up a pointer to a user structure for use by your -callback function. - - png_set_user_transform_info(png_ptr, user_ptr, 0, 0); - -The user_channels and user_depth parameters of this function are ignored -when writing; you can set them to zero as shown. - -You can retrieve the pointer via the function png_get_user_transform_ptr(). -For example: - - voidp write_user_transform_ptr = - png_get_user_transform_ptr(png_ptr); - -It is possible to have libpng flush any pending output, either manually, -or automatically after a certain number of lines have been written. To -flush the output stream a single time call: - - png_write_flush(png_ptr); - -and to have libpng flush the output stream periodically after a certain -number of scanlines have been written, call: - - png_set_flush(png_ptr, nrows); - -Note that the distance between rows is from the last time png_write_flush() -was called, or the first row of the image if it has never been called. -So if you write 50 lines, and then png_set_flush 25, it will flush the -output on the next scanline, and every 25 lines thereafter, unless -png_write_flush() is called before 25 more lines have been written. -If nrows is too small (less than about 10 lines for a 640 pixel wide -RGB image) the image compression may decrease noticeably (although this -may be acceptable for real-time applications). Infrequent flushing will -only degrade the compression performance by a few percent over images -that do not use flushing. - -.SS Writing the image data - -That's it for the transformations. Now you can write the image data. -The simplest way to do this is in one function call. If you have the -whole image in memory, you can just call png_write_image() and libpng -will write the image. You will need to pass in an array of pointers to -each row. This function automatically handles interlacing, so you don't -need to call png_set_interlace_handling() or call this function multiple -times, or any of that other stuff necessary with png_write_rows(). - - png_write_image(png_ptr, row_pointers); - -where row_pointers is: - - png_byte *row_pointers[height]; - -You can point to void or char or whatever you use for pixels. - -If you don't want to write the whole image at once, you can -use png_write_rows() instead. If the file is not interlaced, -this is simple: - - png_write_rows(png_ptr, row_pointers, - number_of_rows); - -row_pointers is the same as in the png_write_image() call. - -If you are just writing one row at a time, you can do this with -a single row_pointer instead of an array of row_pointers: - - png_bytep row_pointer = row; - - png_write_row(png_ptr, row_pointer); - -When the file is interlaced, things can get a good deal more -complicated. The only currently (as of the PNG Specification -version 1.2, dated July 1999) defined interlacing scheme for PNG files -is the "Adam7" interlace scheme, that breaks down an -image into seven smaller images of varying size. libpng will build -these images for you, or you can do them yourself. If you want to -build them yourself, see the PNG specification for details of which -pixels to write when. - -If you don't want libpng to handle the interlacing details, just -use png_set_interlace_handling() and call png_write_rows() the -correct number of times to write all seven sub-images. - -If you want libpng to build the sub-images, call this before you start -writing any rows: - - number_of_passes = - png_set_interlace_handling(png_ptr); - -This will return the number of passes needed. Currently, this -is seven, but may change if another interlace type is added. - -Then write the complete image number_of_passes times. - - png_write_rows(png_ptr, row_pointers, - number_of_rows); - -As some of these rows are not used, and thus return immediately, -you may want to read about interlacing in the PNG specification, -and only update the rows that are actually used. - -.SS Finishing a sequential write - -After you are finished writing the image, you should finish writing -the file. If you are interested in writing comments or time, you should -pass an appropriately filled png_info pointer. If you are not interested, -you can pass NULL. - - png_write_end(png_ptr, info_ptr); - -When you are done, you can free all memory used by libpng like this: - - png_destroy_write_struct(&png_ptr, &info_ptr); - -It is also possible to individually free the info_ptr members that -point to libpng-allocated storage with the following function: - - png_free_data(png_ptr, info_ptr, mask, seq) - mask - identifies data to be freed, a mask - containing the bitwise OR of one or - more of - PNG_FREE_PLTE, PNG_FREE_TRNS, - PNG_FREE_HIST, PNG_FREE_ICCP, - PNG_FREE_PCAL, PNG_FREE_ROWS, - PNG_FREE_SCAL, PNG_FREE_SPLT, - PNG_FREE_TEXT, PNG_FREE_UNKN, - or simply PNG_FREE_ALL - seq - sequence number of item to be freed - (-1 for all items) - -This function may be safely called when the relevant storage has -already been freed, or has not yet been allocated, or was allocated -by the user and not by libpng, and will in those -cases do nothing. The "seq" parameter is ignored if only one item -of the selected data type, such as PLTE, is allowed. If "seq" is not --1, and multiple items are allowed for the data type identified in -the mask, such as text or sPLT, only the n'th item in the structure -is freed, where n is "seq". - -If you allocated data such as a palette that you passed -in to libpng with png_set_*, you must not free it until just before the call to -png_destroy_write_struct(). - -The default behavior is only to free data that was allocated internally -by libpng. This can be changed, so that libpng will not free the data, -or so that it will free data that was allocated by the user with png_malloc() -or png_zalloc() and passed in via a png_set_*() function, with - - png_data_freer(png_ptr, info_ptr, freer, mask) - mask - which data elements are affected - same choices as in png_free_data() - freer - one of - PNG_DESTROY_WILL_FREE_DATA - PNG_SET_WILL_FREE_DATA - PNG_USER_WILL_FREE_DATA - -For example, to transfer responsibility for some data from a read structure -to a write structure, you could use - - png_data_freer(read_ptr, read_info_ptr, - PNG_USER_WILL_FREE_DATA, - PNG_FREE_PLTE|PNG_FREE_tRNS|PNG_FREE_hIST) - png_data_freer(write_ptr, write_info_ptr, - PNG_DESTROY_WILL_FREE_DATA, - PNG_FREE_PLTE|PNG_FREE_tRNS|PNG_FREE_hIST) - -thereby briefly reassigning responsibility for freeing to the user but -immediately afterwards reassigning it once more to the write_destroy -function. Having done this, it would then be safe to destroy the read -structure and continue to use the PLTE, tRNS, and hIST data in the write -structure. - -This function only affects data that has already been allocated. -You can call this function before calling after the png_set_*() functions -to control whether the user or png_destroy_*() is supposed to free the data. -When the user assumes responsibility for libpng-allocated data, the -application must use -png_free() to free it, and when the user transfers responsibility to libpng -for data that the user has allocated, the user must have used png_malloc() -or png_zalloc() to allocate it. - -If you allocated text_ptr.text, text_ptr.lang, and text_ptr.translated_keyword -separately, do not transfer responsibility for freeing text_ptr to libpng, -because when libpng fills a png_text structure it combines these members with -the key member, and png_free_data() will free only text_ptr.key. Similarly, -if you transfer responsibility for free'ing text_ptr from libpng to your -application, your application must not separately free those members. -For a more compact example of writing a PNG image, see the file example.c. - -.SH V. Modifying/Customizing libpng: - -There are two issues here. The first is changing how libpng does -standard things like memory allocation, input/output, and error handling. -The second deals with more complicated things like adding new chunks, -adding new transformations, and generally changing how libpng works. -Both of those are compile-time issues; that is, they are generally -determined at the time the code is written, and there is rarely a need -to provide the user with a means of changing them. - -Memory allocation, input/output, and error handling - -All of the memory allocation, input/output, and error handling in libpng -goes through callbacks that are user-settable. The default routines are -in pngmem.c, pngrio.c, pngwio.c, and pngerror.c, respectively. To change -these functions, call the appropriate png_set_*_fn() function. - -Memory allocation is done through the functions png_malloc() -and png_free(). These currently just call the standard C functions. If -your pointers can't access more then 64K at a time, you will want to set -MAXSEG_64K in zlib.h. Since it is unlikely that the method of handling -memory allocation on a platform will change between applications, these -functions must be modified in the library at compile time. If you prefer -to use a different method of allocating and freeing data, you can use -png_create_read_struct_2() or png_create_write_struct_2() to register -your own functions as described above. -These functions also provide a void pointer that can be retrieved via - - mem_ptr=png_get_mem_ptr(png_ptr); - -Your replacement memory functions must have prototypes as follows: - - png_voidp malloc_fn(png_structp png_ptr, - png_size_t size); - void free_fn(png_structp png_ptr, png_voidp ptr); - -Your malloc_fn() must return NULL in case of failure. The png_malloc() -function will normally call png_error() if it receives a NULL from the -system memory allocator or from your replacement malloc_fn(). - -Your free_fn() will never be called with a NULL ptr, since libpng's -png_free() checks for NULL before calling free_fn(). - -Input/Output in libpng is done through png_read() and png_write(), -which currently just call fread() and fwrite(). The FILE * is stored in -png_struct and is initialized via png_init_io(). If you wish to change -the method of I/O, the library supplies callbacks that you can set -through the function png_set_read_fn() and png_set_write_fn() at run -time, instead of calling the png_init_io() function. These functions -also provide a void pointer that can be retrieved via the function -png_get_io_ptr(). For example: - - png_set_read_fn(png_structp read_ptr, - voidp read_io_ptr, png_rw_ptr read_data_fn) - - png_set_write_fn(png_structp write_ptr, - voidp write_io_ptr, png_rw_ptr write_data_fn, - png_flush_ptr output_flush_fn); - - voidp read_io_ptr = png_get_io_ptr(read_ptr); - voidp write_io_ptr = png_get_io_ptr(write_ptr); - -The replacement I/O functions must have prototypes as follows: - - void user_read_data(png_structp png_ptr, - png_bytep data, png_size_t length); - void user_write_data(png_structp png_ptr, - png_bytep data, png_size_t length); - void user_flush_data(png_structp png_ptr); - -Supplying NULL for the read, write, or flush functions sets them back -to using the default C stream functions. It is an error to read from -a write stream, and vice versa. - -Error handling in libpng is done through png_error() and png_warning(). -Errors handled through png_error() are fatal, meaning that png_error() -should never return to its caller. Currently, this is handled via -setjmp() and longjmp() (unless you have compiled libpng with -PNG_SETJMP_NOT_SUPPORTED, in which case it is handled via PNG_ABORT()), -but you could change this to do things like exit() if you should wish. - -On non-fatal errors, png_warning() is called -to print a warning message, and then control returns to the calling code. -By default png_error() and png_warning() print a message on stderr via -fprintf() unless the library is compiled with PNG_NO_CONSOLE_IO defined -(because you don't want the messages) or PNG_NO_STDIO defined (because -fprintf() isn't available). If you wish to change the behavior of the error -functions, you will need to set up your own message callbacks. These -functions are normally supplied at the time that the png_struct is created. -It is also possible to redirect errors and warnings to your own replacement -functions after png_create_*_struct() has been called by calling: - - png_set_error_fn(png_structp png_ptr, - png_voidp error_ptr, png_error_ptr error_fn, - png_error_ptr warning_fn); - - png_voidp error_ptr = png_get_error_ptr(png_ptr); - -If NULL is supplied for either error_fn or warning_fn, then the libpng -default function will be used, calling fprintf() and/or longjmp() if a -problem is encountered. The replacement error functions should have -parameters as follows: - - void user_error_fn(png_structp png_ptr, - png_const_charp error_msg); - void user_warning_fn(png_structp png_ptr, - png_const_charp warning_msg); - -The motivation behind using setjmp() and longjmp() is the C++ throw and -catch exception handling methods. This makes the code much easier to write, -as there is no need to check every return code of every function call. -However, there are some uncertainties about the status of local variables -after a longjmp, so the user may want to be careful about doing anything after -setjmp returns non-zero besides returning itself. Consult your compiler -documentation for more details. For an alternative approach, you may wish -to use the "cexcept" facility (see http://cexcept.sourceforge.net). - -.SS Custom chunks - -If you need to read or write custom chunks, you may need to get deeper -into the libpng code. The library now has mechanisms for storing -and writing chunks of unknown type; you can even declare callbacks -for custom chunks. However, this may not be good enough if the -library code itself needs to know about interactions between your -chunk and existing `intrinsic' chunks. - -If you need to write a new intrinsic chunk, first read the PNG -specification. Acquire a first level of -understanding of how it works. Pay particular attention to the -sections that describe chunk names, and look at how other chunks were -designed, so you can do things similarly. Second, check out the -sections of libpng that read and write chunks. Try to find a chunk -that is similar to yours and use it as a template. More details can -be found in the comments inside the code. It is best to handle unknown -chunks in a generic method, via callback functions, instead of by -modifying libpng functions. - -If you wish to write your own transformation for the data, look through -the part of the code that does the transformations, and check out some of -the simpler ones to get an idea of how they work. Try to find a similar -transformation to the one you want to add and copy off of it. More details -can be found in the comments inside the code itself. - -.SS Configuring for 16 bit platforms - -You will want to look into zconf.h to tell zlib (and thus libpng) that -it cannot allocate more then 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. - -.SS 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. - -.SS 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 *. - -.SS Configuring for gui/windowing platforms: - -You will need to write new error and warning functions that use the GUI -interface, as described previously, and set them to be the error and -warning functions at the time that png_create_*_struct() is called, -in order to have them available during the structure initialization. -They can be changed later via png_set_error_fn(). On some compilers, -you may also have to change the memory allocators (png_malloc, etc.). - -.SS Configuring for compiler xxx: - -All includes for libpng are in pngconf.h. If you need to add/change/delete -an include, this is the place to do it. The includes that are not -needed outside libpng are protected by the PNG_INTERNAL definition, -which is only defined for those routines inside libpng itself. The -files in libpng proper only include png.h, which includes pngconf.h. - -.SS Configuring zlib: - -There are special functions to configure the compression. Perhaps the -most useful one changes the compression level, which currently uses -input compression values in the range 0 - 9. The library normally -uses the default compression level (Z_DEFAULT_COMPRESSION = 6). Tests -have shown that for a large majority of images, compression values in -the range 3-6 compress nearly as well as higher levels, and do so much -faster. For online applications it may be desirable to have maximum speed -(Z_BEST_SPEED = 1). With versions of zlib after v0.99, you can also -specify no compression (Z_NO_COMPRESSION = 0), but this would create -files larger than just storing the raw bitmap. You can specify the -compression level by calling: - - png_set_compression_level(png_ptr, level); - -Another useful one is to reduce the memory level used by the library. -The memory level defaults to 8, but it can be lowered if you are -short on memory (running DOS, for example, where you only have 640K). -Note that the memory level does have an effect on compression; among -other things, lower levels will result in sections of incompressible -data being emitted in smaller stored blocks, with a correspondingly -larger relative overhead of up to 15% in the worst case. - - png_set_compression_mem_level(png_ptr, level); - -The other functions are for configuring zlib. They are not recommended -for normal use and may result in writing an invalid PNG file. See -zlib.h for more information on what these mean. - - png_set_compression_strategy(png_ptr, - strategy); - png_set_compression_window_bits(png_ptr, - window_bits); - png_set_compression_method(png_ptr, method); - png_set_compression_buffer_size(png_ptr, size); - -.SS Controlling row filtering - -If you want to control whether libpng uses filtering or not, which -filters are used, and how it goes about picking row filters, you -can call one of these functions. The selection and configuration -of row filters can have a significant impact on the size and -encoding speed and a somewhat lesser impact on the decoding speed -of an image. Filtering is enabled by default for RGB and grayscale -images (with and without alpha), but not for paletted images nor -for any images with bit depths less than 8 bits/pixel. - -The 'method' parameter sets the main filtering method, which is -currently only '0' in the PNG 1.2 specification. The 'filters' -parameter sets which filter(s), if any, should be used for each -scanline. Possible values are PNG_ALL_FILTERS and PNG_NO_FILTERS -to turn filtering on and off, respectively. - -Individual filter types are PNG_FILTER_NONE, PNG_FILTER_SUB, -PNG_FILTER_UP, PNG_FILTER_AVG, PNG_FILTER_PAETH, which can be bitwise -ORed together with '|' to specify one or more filters to use. -These filters are described in more detail in the PNG specification. -If you intend to change the filter type during the course of writing -the image, you should start with flags set for all of the filters -you intend to use so that libpng can initialize its internal -structures appropriately for all of the filter types. (Note that this -means the first row must always be adaptively filtered, because libpng -currently does not allocate the filter buffers until png_write_row() -is called for the first time.) - - filters = PNG_FILTER_NONE | PNG_FILTER_SUB - PNG_FILTER_UP | PNG_FILTER_AVE | - PNG_FILTER_PAETH | PNG_ALL_FILTERS; - - png_set_filter(png_ptr, PNG_FILTER_TYPE_BASE, - filters); - The second parameter can also be - PNG_INTRAPIXEL_DIFFERENCING if you are - writing a PNG to be embedded in a MNG - datastream. This parameter must be the - same as the value of filter_method used - in png_set_IHDR(). - -It is also possible to influence how libpng chooses from among the -available filters. This is done in one or both of two ways - by -telling it how important it is to keep the same filter for successive -rows, and by telling it the relative computational costs of the filters. - - double weights[3] = {1.5, 1.3, 1.1}, - costs[PNG_FILTER_VALUE_LAST] = - {1.0, 1.3, 1.3, 1.5, 1.7}; - - png_set_filter_heuristics(png_ptr, - PNG_FILTER_HEURISTIC_WEIGHTED, 3, - weights, costs); - -The weights are multiplying factors that indicate to libpng that the -row filter should be the same for successive rows unless another row filter -is that many times better than the previous filter. In the above example, -if the previous 3 filters were SUB, SUB, NONE, the SUB filter could have a -"sum of absolute differences" 1.5 x 1.3 times higher than other filters -and still be chosen, while the NONE filter could have a sum 1.1 times -higher than other filters and still be chosen. Unspecified weights are -taken to be 1.0, and the specified weights should probably be declining -like those above in order to emphasize recent filters over older filters. - -The filter costs specify for each filter type a relative decoding cost -to be considered when selecting row filters. This means that filters -with higher costs are less likely to be chosen over filters with lower -costs, unless their "sum of absolute differences" is that much smaller. -The costs do not necessarily reflect the exact computational speeds of -the various filters, since this would unduly influence the final image -size. - -Note that the numbers above were invented purely for this example and -are given only to help explain the function usage. Little testing has -been done to find optimum values for either the costs or the weights. - -.SS 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_. - -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. - -.SS Requesting debug printout - -The macro definition PNG_DEBUG can be used to request debugging -printout. Set it to an integer value in the range 0 to 3. Higher -numbers result in increasing amounts of debugging information. The -information is printed to the "stderr" file, unless another file -name is specified in the PNG_DEBUG_FILE macro definition. - -When PNG_DEBUG > 0, the following functions (macros) become available: - - png_debug(level, message) - png_debug1(level, message, p1) - png_debug2(level, message, p1, p2) - -in which "level" is compared to PNG_DEBUG to decide whether to print -the message, "message" is the formatted string to be printed, -and p1 and p2 are parameters that are to be embedded in the string -according to printf-style formatting directives. For example, - - png_debug1(2, "foo=%d\n", foo); - -is expanded to - - if(PNG_DEBUG > 2) - fprintf(PNG_DEBUG_FILE, "foo=%d\n", foo); - -When PNG_DEBUG is defined but is zero, the macros aren't defined, but you -can still use PNG_DEBUG to control your own debugging: - - #ifdef PNG_DEBUG - fprintf(stderr, ... - #endif - -When PNG_DEBUG = 1, the macros are defined, but only png_debug statements -having level = 0 will be printed. There aren't any such statements in -this version of libpng, but if you insert some they will be printed. - -.SH VII. MNG support - -The MNG specification (available at http://www.libpng.org/pub/mng) allows -certain extensions to PNG for PNG images that are embedded in MNG datastreams. -Libpng can support some of these extensions. To enable them, use the -png_permit_mng_features() function: - - feature_set = png_permit_mng_features(png_ptr, mask) - mask is a png_uint_32 containing the bitwise OR of the - features you want to enable. These include - PNG_FLAG_MNG_EMPTY_PLTE - PNG_FLAG_MNG_FILTER_64 - PNG_ALL_MNG_FEATURES - feature_set is a png_uint_32 that is the bitwise AND of - your mask with the set of MNG features that is - supported by the version of libpng that you are using. - -It is an error to use this function when reading or writing a standalone -PNG file with the PNG 8-byte signature. The PNG datastream must be wrapped -in a MNG datastream. As a minimum, it must have the MNG 8-byte signature -and the MHDR and MEND chunks. Libpng does not provide support for these -or any other MNG chunks; your application must provide its own support for -them. You may wish to consider using libmng (available at -http://www.libmng.com) instead. - -.SH VIII. Changes to Libpng from version 0.88 - -It should be noted that versions of libpng later than 0.96 are not -distributed by the original libpng author, Guy Schalnat, nor by -Andreas Dilger, who had taken over from Guy during 1996 and 1997, and -distributed versions 0.89 through 0.96, but rather by another member -of the original PNG Group, Glenn Randers-Pehrson. Guy and Andreas are -still alive and well, but they have moved on to other things. - -The old libpng functions png_read_init(), png_write_init(), -png_info_init(), png_read_destroy(), and png_write_destroy() have been -moved to PNG_INTERNAL in version 0.95 to discourage their use. These -functions will be removed from libpng version 2.0.0. - -The preferred method of creating and initializing the libpng structures is -via the png_create_read_struct(), png_create_write_struct(), and -png_create_info_struct() because they isolate the size of the structures -from the application, allow version error checking, and also allow the -use of custom error handling routines during the initialization, which -the old functions do not. The functions png_read_destroy() and -png_write_destroy() do not actually free the memory that libpng -allocated for these structs, but just reset the data structures, so they -can be used instead of png_destroy_read_struct() and -png_destroy_write_struct() if you feel there is too much system overhead -allocating and freeing the png_struct for each image read. - -Setting the error callbacks via png_set_message_fn() before -png_read_init() as was suggested in libpng-0.88 is no longer supported -because this caused applications that do not use custom error functions -to fail if the png_ptr was not initialized to zero. It is still possible -to set the error callbacks AFTER png_read_init(), or to change them with -png_set_error_fn(), which is essentially the same function, but with a new -name to force compilation errors with applications that try to use the old -method. - -Starting with version 1.0.7, you can find out which version of the library -you are using at run-time: - - png_uint_32 libpng_vn = png_access_version_number(); - -The number libpng_vn is constructed from the major version, minor -version with leading zero, and release number with leading zero, -(e.g., libpng_vn for version 1.0.7 is 10007). - -You can also check which version of png.h you used when compiling your -application: - - png_uint_32 application_vn = PNG_LIBPNG_VER; - -.SH IX. Y2K Compliance in libpng - -December 18, 2008 - -Since the PNG Development group is an ad-hoc body, we can't make -an official declaration. - -This is your unofficial assurance that libpng from version 0.71 and -upward through 1.2.34 are Y2K compliant. It is my belief that earlier -versions were also Y2K compliant. - -Libpng only has three year fields. One is a 2-byte unsigned integer that -will hold years up to 65535. The other two hold the date in text -format, and will hold years up to 9999. - -The integer is - "png_uint_16 year" in png_time_struct. - -The strings are - "png_charp time_buffer" in png_struct and - "near_time_buffer", which is a local character string in png.c. - -There are seven time-related functions: - - png_convert_to_rfc_1123() in png.c - (formerly png_convert_to_rfc_1152() in error) - png_convert_from_struct_tm() in pngwrite.c, called - in pngwrite.c - png_convert_from_time_t() in pngwrite.c - png_get_tIME() in pngget.c - png_handle_tIME() in pngrutil.c, called in pngread.c - png_set_tIME() in pngset.c - png_write_tIME() in pngwutil.c, called in pngwrite.c - -All appear to handle dates properly in a Y2K environment. 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 applications using -libpng are not passing 4-digit years into the png_convert_to_rfc_1123() -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. The libpng documentation has always -stated that it works with 4-digit years, and the APIs have been -documented as such. - -The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned -integer to hold the year, and can hold years as large as 65535. - -zlib, upon which libpng depends, is also Y2K compliant. It contains -no date-related code. - - - Glenn Randers-Pehrson - libpng maintainer - PNG Development Group - -.SH NOTE - -Note about libpng version numbers: - -Due to various miscommunications, unforeseen code incompatibilities -and occasional factors outside the authors' control, version numbering -on the library has not always been consistent and straightforward. -The following table summarizes matters since version 0.89c, which was -the first widely used release: -
