The preprocessor + splits adjacent @ signs with a space; this changes the concatentation + token from @-@-@ to PNG_JOIN; that should work with all compiler + preprocessors. + Paeth filter speed improvements from work by Siarhei Siamashka. This + changes the 'Paeth' reconstruction function to improve the GCC code + generation on x86. The changes are only part of the suggested ones; + just the changes that definitely improve speed and remain simple. + The changes also slightly increase the clarity of the code. + +Version 1.5.7beta02 [November 11, 2011] + Check compression_type parameter in png_get_iCCP and remove spurious + casts. The compression_type parameter is always assigned to, so must + be non-NULL. The cast of the profile length potentially truncated the + value unnecessarily on a 16-bit int system, so the cast of the (byte) + compression type to (int) is specified by ANSI-C anyway. + Fixed FP division by zero in pngvalid.c; the 'test_pixel' code left + the sBIT fields in the test pixel as 0, which resulted in a floating + point division by zero which was irrelevant but causes systems where + FP exceptions cause a crash. Added code to pngvalid to turn on FP + exceptions if the appropriate glibc support is there to ensure this is + tested in the future. + Updated scripts/pnglibconf.mak and scripts/makefile.std to handle the + new PNG_JOIN macro. + Added versioning to pnglibconf.h comments. + Simplified read/write API initial version; basic read/write tested on + a variety of images, limited documentation (in the header file.) + Installed more accurate linear to sRGB conversion tables. The slightly + modified tables reduce the number of 16-bit values that + convert to an off-by-one 8-bit value. The "makesRGB.c" code that was used + to generate the tables is now in a contrib/sRGBtables sub-directory. + +Version 1.5.7beta03 [November 17, 2011] + Removed PNG_CONST from the sRGB table declarations in pngpriv.h and png.c + Added run-time detection of NEON support. + Added contrib/libtests; includes simplified API test and timing test and + a color conversion utility for rapid checking of failed 'pngstest' results. + Multiple transform bug fixes plus a work-round for double gamma correction. + libpng does not support more than one transform that requires linear data + at once - if this is tried typically the results is double gamma + correction. Since the simplified APIs can need rgb to gray combined with + a compose operation it is necessary to do one of these outside the main + libpng transform code. This check-in also contains fixes to various bugs + in the simplified APIs themselves and to some bugs in compose and rgb to + gray (on palette) itself. + Fixes for C++ compilation using g++ When libpng source is compiled + using g++. The compiler imposes C++ rules on the C source; thus it + is desireable to make the source work with either C or C++ rules + without throwing away useful error information. This change adds + png_voidcast to allow C semantic (void*) cases or the corresponding + C++ static_cast operation, as appropriate. + Added --noexecstack to assembler file compilation. GCC does not set + this on assembler compilation, even though it does on C compilation. + This creates security issues if assembler code is enabled; the + work-around is to set it by default in the flags for $(CCAS) + Work around compilers that don't support declaration of const data. Some + compilers fault 'extern const' data declarations (because the data is + not initialized); this turns on const-ness only for compilers where + this is known to work. + +Version 1.5.7beta04 [November 17, 2011] + Since the gcc driver does not recognize the --noexecstack flag, we must + use the -Wa prefix to have it passed through to the assembler. + Also removed a duplicate setting of this flag. + Added files that were omitted from the libpng-1.5.7beta03 zip distribution. + +Version 1.5.7beta05 [November 25, 2011] + Removed "zTXt" from warning in generic chunk decompression function. + Validate time settings passed to pngset() and png_convert_to_rfc1123() + (Frank Busse). + Added MINGW support to CMakeLists.txt + Reject invalid compression flag or method when reading the iTXt chunk. + Backed out 'simplified' API changes. The API seems too complex and there + is a lack of consensus or enthusiasm for the proposals. The API also + reveals significant bugs inside libpng (double gamma correction and the + known bug of being unable to retrieve a corrected palette). It seems + better to wait until the bugs, at least, are corrected. + Moved pngvalid.c into contrib/libtests + Rebuilt Makefile.in, configure, etc., with autoconf-2.68 + +Version 1.5.7rc01 [December 1, 2011] + Replaced an "#if" with "#ifdef" in pngrtran.c + Revised #if PNG_DO_BC block in png.c (use #ifdef and add #else) + +Version 1.5.7rc02 [December 5, 2011] + Revised project files and contrib/pngvalid/pngvalid.c to account for + the relocation of pngvalid into contrib/libtests. + Revised pngconf.h to use " __declspec(restrict)" only when MSC_VER >= 1400, + as in libpng-1.5.4. + Put CRLF line endings in the owatcom project files. + +Version 1.5.7rc03 [December 7, 2011] + Updated CMakeLists.txt to account for the relocation of pngvalid.c + +Version 1.5.7 [December 15, 2011] + Minor fixes to pngvalid.c for gcc 4.6.2 compatibility to remove warnings + reported by earlier versions. + Fixed minor memset/sizeof errors in pngvalid.c. + +Version 1.6.0beta01 [December 15, 2011] + Removed machine-generated configure files from the GIT repository (they will + continue to appear in the tarball distributions and in the libpng15 and + earlier GIT branches). + Restored the new 'simplified' API, which was started in libpng-1.5.7beta02 + but later deleted from libpng-1.5.7beta05. + Added example programs for the new 'simplified' API. + Added ANSI-C (C90) headers and require them, and take advantage of the + change. Also fixed some of the projects/* and contrib/* files that needed + updates for libpng16 and the move of pngvalid.c. + With this change the required ANSI-C header files are assumed to exist: the + implementation must provide float.h, limits.h, stdarg.h and stddef.h and + libpng relies on limits.h and stddef.h existing and behaving as defined + (the other two required headers aren't used). Non-ANSI systems that don't + have stddef.h or limits.h will have to provide an appropriate fake + containing the relevant types and #defines. + The use of FAR/far has been eliminated and the definition of png_alloc_size_t + is now controlled by a flag so that 'small size_t' systems can select it + if necessary. Libpng 1.6 may not currently work on such systems -- it + seems likely that it will ask 'malloc' for more than 65535 bytes with any + image that has a sufficiently large row size (rather than simply failing + to read such images). + New tools directory containing tools used to generate libpng code. + Fixed race conditions in parallel make builds. With higher degrees of + parallelism during 'make' the use of the same temporary file names such + as 'dfn*' can result in a race where a temporary file from one arm of the + build is deleted or overwritten in another arm. This changes the + temporary files for suffix rules to always use $* and ensures that the + non-suffix rules use unique file names. + +Version 1.6.0beta02 [December 21, 2011] + Correct configure builds where build and source directories are separate. + The include path of 'config.h' was erroneously made relative in pngvalid.c + in libpng 1.5.7. + +Version 1.6.0beta03 [December 22, 2011] + Start-up code size improvements, error handler flexibility. These changes + alter how the tricky allocation of the initial png_struct and png_info + structures are handled. png_info is now handled in pretty much the same + way as everything else, except that the allocations handle NULL return + silently. png_struct is changed in a similar way on allocation and on + deallocation a 'safety' error handler is put in place (which should never + be required). The error handler itself is changed to permit mismatches + in the application and libpng error buffer size; however, this means a + silent change to the API to return the jmp_buf if the size doesn't match + the size from the libpng compilation; libpng now allocates the memory and + this may fail. Overall these changes result in slight code size + reductions; however, this is a reduction in code that is always executed + so is particularly valuable. Overall on a 64-bit system the libpng DLL + decreases in code size by 1733 bytes. pngerror.o increases in size by + about 465 bytes because of the new functionality. + Added png_convert_to_rfc1123_buffer() and deprecated png_convert_to_rfc1123() + to avoid including a spurious buffer in the png_struct. + +Version 1.6.0beta04 [December 30, 2011] + Regenerated configure scripts with automake-1.11.2 + Eliminated png_info_destroy(). It is now used only in png.c and only calls + one other internal function and memset(). + Enabled png_get_sCAL_fixed() if floating point APIs are enabled. Previously + it was disabled whenever internal fixed point arithmetic was selected, + which meant it didn't exist even on systems where FP was available but not + preferred. + Added pngvalid.c compile time checks for const APIs. + Implemented 'restrict' for png_info and png_struct. Because of the way + libpng works both png_info and png_struct are always accessed via a + single pointer. This means adding C99 'restrict' to the pointer gives + the compiler some opportunity to optimize the code. This change allows + that. + Moved AC_MSG_CHECKING([if libraries can be versioned]) later to the proper + location in configure.ac (Gilles Espinasse). + Changed png_memcpy to C assignment where appropriate. Changed all those + uses of png_memcpy that were doing a simple assignment to assignments + (all those cases where the thing being copied is a non-array C L-value). + Added some error checking to png_set_*() routines. + Removed the reference to the non-exported function png_memcpy() from + example.c. + Fixed the Visual C 64-bit build - it requires jmp_buf to be aligned, but + it had become misaligned. + Revised contrib/pngminus/pnm2png.c to avoid warnings when png_uint_32 + and unsigned long are of different sizes. + +Version 1.6.0beta05 [January 15, 2012] + Updated manual with description of the simplified API (copied from png.h) + Fix bug in pngerror.c: some long warnings were being improperly truncated + (CVE-2011-3464, bug introduced in libpng-1.5.3beta05). + +Version 1.6.0beta06 [January 24, 2012] + Added palette support to the simplified APIs. This commit + changes some of the macro definitions in png.h, app code + may need corresponding changes. + Increased the formatted warning buffer to 192 bytes. + Added color-map support to simplified API. This is an initial version for + review; the documentation has not yet been updated. + Fixed Min/GW uninstall to remove libpng.dll.a + +Version 1.6.0beta07 [January 28, 2012] + Eliminated Intel icc/icl compiler warnings. The Intel (GCC derived) + compiler issues slightly different warnings from those issued by the + current vesions of GCC. This eliminates those warnings by + adding/removing casts and small code rewrites. + Updated configure.ac from autoupdate: added --enable-werror option. + Also some layout regularization and removal of introduced tab characters + (replaced with 3-character indentation). Obsolete macros identified by + autoupdate have been removed; the replacements are all in 2.59 so + the pre-req hasn't been changed. --enable-werror checks for support + for -Werror (or the given argument) in the compiler. This mimics the + gcc configure option by allowing -Werror to be turned on safely; without + the option the tests written in configure itself fail compilation because + they cause compiler warnings. + Rewrote autogen.sh to run autoreconf instead of running tools one-by-one. + Conditionalize the install rules for MINGW and CYGWIN in CMakeLists.txt and + set CMAKE_LIBRARY_OUTPUT_DIRECTORY to "lib" on all platforms (C. Yapp). + Freeze libtool files in the 'scripts' directory. This version of autogen.sh + attempts to dissuade people from running it when it is not, or should not, + be necessary. In fact, autogen.sh does not work when run in a libpng + directory extracted from a tar distribution anymore. You must run it in + a GIT clone instead. + Added two images to contrib/pngsuite (1-bit and 2-bit transparent grayscale), + and renamed three whose names were inconsistent with those in + pngsuite/README.txt. + +Version 1.6.0beta08 [February 1, 2012] + Fixed Image::colormap misalignment in pngstest.c + Check libtool/libtoolize version number (2.4.2) in configure.ac + Divide test-pngstest.sh into separate pngstest runs for basic and + transparent images. + Moved automake options to AM_INIT_AUTOMAKE in configure.ac + Added color-tests, silent-rules (Not yet implemented in Makefile.am) and + version checking to configure.ac + Improved pngstest speed by not doing redundant tests and add const to + the background parameter of png_image_finish_read. The --background + option is now done automagically only when required, so that commandline + option no longer exists. + Cleaned up pngpriv.h to consistently declare all functions and data. + Also eliminated PNG_CONST_DATA, which is apparently not needed but we + can't be sure until it is gone. + Added symbol prefixing that allows all the libpng external symbols + to be prefixed (suggested by Reuben Hawkins). + Updated "ftbb*.png" list in the owatcom and vstudio projects. + Fixed 'prefix' builds on clean systems. The generation of pngprefix.h + should not require itself. + Updated INSTALL to explain that autogen.sh must be run in a GIT clone, + not in a libpng directory extracted from a tar distribution. + +Version 1.6.0beta09 [February 1, 2012] + Reverted the prebuilt configure files to libpng-1.6.0beta05 condition. + +Version 1.6.0beta10 [February 3, 2012] + Added Z_SOLO for zlib-1.2.6+ and correct pngstest tests + Updated list of test images in CMakeLists.txt + Updated the prebuilt configure files to current condition. + Revised INSTALL information about autogen.sh; it works in tar distributions. + +Version 1.6.0beta11 [February 16, 2012] + Fix character count in pngstest command in projects/owatcom/pngstest.tgt + Revised test-pngstest.sh to report PASS/FAIL for each image. + Updated documentation about the simplified API. + Corrected estimate of error in libpng png_set_rgb_to_gray API. The API is + extremely inaccurate for sRGB conversions because it uses an 8-bit + intermediate linear value and it does not use the sRGB transform, so it + suffers from the known instability in gamma transforms for values close + to 0 (see Poynton). The net result is that the calculation has a maximum + error of 14.99/255; 0.5/255^(1/2.2). pngstest now uses 15 for the + permitted 8-bit error. This may still not be enough because of arithmetic + error. + Removed some unused arrays (with #ifdef) from png_read_push_finish_row(). + Fixed a memory overwrite bug in simplified read of RGB PNG with + non-linear gamma Also bugs in the error checking in pngread.c and changed + quite a lot of the checks in pngstest.c to be correct; either correctly + written or not over-optimistic. The pngstest changes are insufficient to + allow all possible RGB transforms to be passed; pngstest cmppixel needs + to be rewritten to make it clearer which errors it allows and then changed + to permit known inaccuracies. + Removed tests for no-longer-used *_EMPTY_PLTE_SUPPORTED from pngstruct.h + Fixed fixed/float API export conditionals. 1) If FIXED_POINT or + FLOATING_POINT options were switched off, png.h ended up with lone ';' + characters. This is not valid ANSI-C outside a function. The ';' + characters have been moved inside the definition of PNG_FP_EXPORT and + PNG_FIXED_EXPORT. 2) If either option was switched off, the declaration + of the corresponding functions were completely omitted, even though some + of them are still used internally. The result is still valid, but + produces warnings from gcc with some warning options (including -Wall). The + fix is to cause png.h to declare the functions with PNG_INTERNAL_FUNCTION + when png.h is included from pngpriv.h. + Check for invalid palette index while reading paletted PNG. When one is + found, issue a warning and increase png_ptr->num_palette accordingly. + Apps are responsible for checking to see if that happened. + +Version 1.6.0beta12 [February 18, 2012] + Do not increase num_palette on invalid_index. + Relocated check for invalid palette index to pngrtran.c, after unpacking + the sub-8-bit pixels. + Fixed CVE-2011-3026 buffer overrun bug. This bug was introduced when + iCCP chunk support was added at libpng-1.0.6. Deal more correctly with the + test on iCCP chunk length. Also removed spurious casts that may hide + problems on 16-bit systems. + +Version 1.6.0beta13 [February 24, 2012] + Eliminated redundant png_push_read_tEXt|zTXt|iTXt|unknown code from + pngpread.c and use the sequential png_handle_tEXt, etc., in pngrutil.c; + now that png_ptr->buffer is inaccessible to applications, the special + handling is no longer useful. + Added PNG_SAFE_LIMITS feature to pnglibconf.dfa, pngpriv.h, and new + pngusr.dfa to reset the user limits to safe ones if PNG_SAFE_LIMITS is + defined. To enable, use "CPPFLAGS=-DPNG_SAFE_LIMITS_SUPPORTED=1" on the + configure command or put #define PNG_SAFE_LIMITS_SUPPORTED in + pnglibconf.h.prebuilt and pnglibconf.h. + +Version 1.6.0beta14 [February 27, 2012] + Added information about the new limits in the manual. + Updated Makefile.in + +Version 1.6.0beta15 [March 2, 2012] + Removed unused "current_text" members of png_struct and the png_free() + of png_ptr->current_text from pngread.c + Rewrote pngstest.c for substantial speed improvement. + Fixed transparent pixel and 16-bit rgb tests in pngstest and removed a + spurious check in pngwrite.c + Added PNG_IMAGE_FLAG_FAST for the benefit of applications that store + intermediate files, or intermediate in-memory data, while processing + image data with the simplified API. The option makes the files larger + but faster to write and read. pngstest now uses this by default; this + can be disabled with the --slow option. + Improved pngstest fine tuning of error numbers, new test file generator. + The generator generates images that test the full range of sample values, + allow the error numbers in pngstest to be tuned and checked. makepng + also allows generation of images with extra chunks, although this is + still work-in-progress. + Added check for invalid palette index while reading. + Fixed some bugs in ICC profile writing. The code should now accept + all potentially valid ICC profiles and reject obviously invalid ones. + It now uses png_error() to do so rather than casually writing a PNG + without the necessary color data. + Removed whitespace from the end of lines in all source files and scripts. + +Version 1.6.0beta16 [March 6, 2012] + Relocated palette-index checking function from pngrutil.c to pngtrans.c + Added palette-index checking while writing. + Changed png_inflate() and calling routines to avoid overflow problems. + This is an intermediate check-in that solves the immediate problems and + introduces one performance improvement (avoiding a copy via png_ptr->zbuf.) + Further changes will be made to make ICC profile handling more secure. + Fixed build warnings (MSVC, GCC, GCC v3). Cygwin GCC with default options + declares 'index' as a global, causing a warning if it is used as a local + variable. GCC 64-bit warns about assigning a (size_t) (unsigned 64-bit) + to an (int) (signed 32-bit). MSVC, however, warns about using the + unary '-' operator on an unsigned value (even though it is well defined + by ANSI-C to be ~x+1). The padding calculation was changed to use a + different method. Removed the tests on png_ptr->pass. + Added contrib/libtests/tarith.c to test internal arithmetic functions from + png.c. This is a libpng maintainer program used to validate changes to the + internal arithmetic functions. + Made read 'inflate' handling like write 'deflate' handling. The read + code now claims and releases png_ptr->zstream, like the write code. + The bug whereby the progressive reader failed to release the zstream + is now fixed, all initialization is delayed, and the code checks for + changed parameters on deflate rather than always calling + deflatedEnd/deflateInit. + Validate the zTXt strings in pngvalid. + Added code to validate the windowBits value passed to deflateInit2(). + If the call to deflateInit2() is wrong a png_warning will be issued + (in fact this is harmless, but the PNG data produced may be sub-optimal). + +Version 1.6.0beta17 [March 10, 2012] + Fixed PNG_LIBPNG_BUILD_BASE_TYPE definition. + Reject all iCCP chunks after the first, even if the first one is invalid. + Deflate/inflate was reworked to move common zlib calls into single + functions [rw]util.c. A new shared keyword check routine was also added + and the 'zbuf' is no longer allocated on progressive read. It is now + possible to call png_inflate() incrementally. A warning is no longer + issued if the language tag or translated keyword in the iTXt chunk + has zero length. + If benign errors are disabled use maximum window on ancilliary inflate. + This works round a bug introduced in 1.5.4 where compressed ancillary + chunks could end up with a too-small windowBits value in the deflate + header. + +Version 1.6.0beta18 [March 16, 2012] + Issue a png_benign_error() instead of png_warning() about bad palette index. + In pngtest, treat benign errors as errors if "-strict" is present. + Fixed an off-by-one error in the palette index checking function. + Fixed a compiler warning under Cygwin (Windows-7, 32-bit system) + Revised example.c to put text strings in a temporary character array + instead of directly assigning string constants to png_textp members. + This avoids compiler warnings when -Wwrite-strings is enabled. + Added output flushing to aid debugging under Visual Studio. Unfortunately + this is necessary because the VS2010 output window otherwise simply loses + the error messages on error (they weren't flushed to the window before + the process exited, apparently!) + Added configuration support for benign errors and changed the read + default. Also changed some warnings in the iCCP and sRGB handling + from to benign errors. Configuration now makes read benign + errors warnings and write benign errors to errors by default (thus + changing the behavior on read). The simplified API always forces + read benign errors to warnings (regardless of the system default, unless + this is disabled in which case the simplified API can't be built.) + +Version 1.6.0beta19 [March 18, 2012] + Work around for duplicate row start calls; added warning messages. + This turns on PNG_FLAG_DETECT_UNINITIALIZED to detect app code that + fails to call one of the 'start' routines (not enabled in libpng-1.5 + because it is technically an API change, since it did normally work + before.) It also makes duplicate calls to png_read_start_row (an + internal function called at the start of the image read) benign, as + they were before changes to use png_inflate_claim. Somehow webkit is + causing this to happen; this is probably a mis-feature in the zlib + changes so this commit is only a work-round. + Removed erroneous setting of DETECT_UNINITIALIZED and added more + checks. The code now does a png_error if an attempt is made to do the + row initialization twice; this is an application error and it has + serious consequences because the transform data in png_struct is + changed by each call. + Added application error reporting and added chunk names to read + benign errors; also added --strict to pngstest - not enabled + yet because a warning is produced. + Avoid the double gamma correction warning in the simplified API. + This allows the --strict option to pass in the pngstest checks + +Version 1.6.0beta20 [March 29, 2012] + Changed chunk handler warnings into benign errors, incrementally load iCCP + Added checksum-icc.c to contrib/tools + Prevent PNG_EXPAND+PNG_SHIFT doing the shift twice. + Recognize known sRGB ICC profiles while reading; prefer writing the + iCCP profile over writing the sRGB chunk, controlled by the + PNG_sRGB_PROFILE_CHECKS option. + Revised png_set_text_2() to avoid potential memory corruption (fixes + CVE-2011-3048, also known as CVE-2012-3425). + +Version 1.6.0beta21 [April 27, 2012] + Revised scripts/makefile.darwin: use system zlib; remove quotes around + architecture list; add missing ppc architecture; add architecture options + to shared library link; don't try to create a shared lib based on missing + RELEASE variable. + Enable png_set_check_for_invalid_index() for both read and write. + Removed #ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED in pngpriv.h around + declaration of png_handle_unknown(). + Added -lssp_nonshared in a comment in scripts/makefile.freebsd + and changed deprecated NOOBJ and NOPROFILE to NO_OBJ and NO_PROFILE. + +Version 1.6.0beta22 [May 23, 2012] + Removed need for -Wno-cast-align with clang. clang correctly warns on + alignment increasing pointer casts when -Wcast-align is passed. This + fixes the cases that clang warns about either by eliminating the + casts from png_bytep to png_uint_16p (pngread.c), or, for pngrutil.c + where the cast is previously verified or pngstest.c where it is OK, by + introducing new png_aligncast macros to do the cast in a way that clang + accepts. + +Version 1.6.0beta23 [June 6, 2012] + Revised CMakeLists.txt to not attempt to make a symlink under mingw. + Made fixes for new optimization warnings from gcc 4.7.0. The compiler + performs an optimization which is safe; however it then warns about it. + Changing the type of 'palette_number' in pngvalid.c removes the warning. + Do not depend upon a GCC feature macro being available for use in generating + the linker mapfile symbol prefix. + Improved performance of new do_check_palette_indexes() function (only + update the value when it actually increases, move test for whether + the check is wanted out of the function. + +Version 1.6.0beta24 [June 7, 2012] + Don't check palette indexes if num_palette is 0 (as it can be in MNG files). + +Version 1.6.0beta25 [June 16, 2012] + Revised png_set_keep_unknown_chunks() so num_chunks < 0 means ignore all + unknown chunks and all known chunks except for IHDR, PLTE, tRNS, IDAT, + and IEND. Previously it only meant ignore all unknown chunks, the + same as num_chunks == 0. Revised png_image_skip_unused_chunks() to + provide a list of chunks to be processed instead of a list of chunks to + ignore. Revised contrib/gregbook/readpng2.c accordingly. + +Version 1.6.0beta26 [July 10, 2012] + Removed scripts/makefile.cegcc from the *.zip and *.7z distributions; it + depends on configure, which is not included in those archives. + Moved scripts/chkfmt to contrib/tools. + Changed "a+w" to "u+w" in Makefile.in to fix CVE-2012-3386. + +Version 1.6.0beta27 [August 11, 2012] + Do not compile PNG_DEPRECATED, PNG_ALLOC and PNG_PRIVATE when __GNUC__ < 3. + Do not use __restrict when GNUC is <= 3.1 + Removed references to png_zalloc() and png_zfree() from the manual. + Fixed configurations where floating point is completely disabled. Because + of the changes to support symbol prefixing PNG_INTERNAL_FUNCTION declares + floating point APIs during libpng builds even if they are completely + disabled. This requires the png floating point types (png_double*) to be + declared even though the functions are never actually defined. This + change provides a dummy definition so that the declarations work, yet any + implementation will fail to compile because of an incomplete type. + Re-eliminated the use of strcpy() in pngtest.c. An unncessary use of + strcpy() was accidentally re-introduced in libpng16; this change replaces + it with strncpy(). + Eliminated use of png_sizeof(); use sizeof() instead. + Use a consistent style for (sizeof type) and (sizeof (array)) + Cleanup of png_set_filler(). This function does very different things on + read and write. In libpng 1.6 the two cases can be distinguished and + considerable code cleanup, and extra error checking, is possible. This + makes calls on the write side that have no effect be ignored with a + png_app_error(), which can be disabled in the app using + png_set_benign_errors(), and removes the spurious use of usr_channels + on the read side. + Insist on autotools 1.12.1 for git builds because there are security issues + with 1.12 and insisting on anything less would allow 1.12 to be used. + Removed info_ptr->signature[8] from WRITE-only builds. + Add some conditions for compiling png_fixed(). This is a small function + but it requires "-lm" on some platforms. + Cause pngtest --strict to fail on any warning from libpng (not just errors) + and cause it not to fail at the comparison step if libpng lacks support + for writing chunks that it reads from the input (currently only implemented + for compressed text chunks). + Make all three "make check" test programs work without READ or WRITE support. + Now "make check" will succeed even if libpng is compiled with -DPNG_NO_READ + or -DPNG_NO_WRITE. The tests performed are reduced, but the basic reading + and writing of a PNG file is always tested by one or more of the tests. + Consistently use strlen(), memset(), memcpy(), and memcmp() instead of the + png_strlen(), png_memset(), png_memcpy(), and png_memcmp() macros. + Removed the png_sizeof(), png_strlen(), png_memset(), png_memcpy(), and + png_memcmp() macros. + Work around gcc 3.x and Microsoft Visual Studio 2010 complaints. Both object + to the split initialization of num_chunks. + +Version 1.6.0beta28 [August 29, 2012] + Unknown handling fixes and clean up. This adds more correct option + control of the unknown handling, corrects the pre-existing bug where + the per-chunk 'keep' setting is ignored and makes it possible to skip + IDAT chunks in the sequential reader (broken in earlier 1.6 versions). + There is a new test program, test-unknown.c, which is a work in progress + (not currently part of the test suite). Comments in the header files now + explain how the unknown handling works. + Allow fine grain control of unknown chunk APIs. This change allows + png_set_keep_unknown_chunks() to be turned off if not required and causes + both read and write to behave appropriately (on read this is only possible + if the user callback is used to handle unknown chunks). The change + also removes the support for storing unknown chunks in the info_struct + if the only unknown handling enabled is via the callback, allowing libpng + to be configured with callback reading and none of the unnecessary code. + Corrected fix for unknown handling in pngtest. This reinstates the + libpng handling of unknown chunks other than vpAg and sTER (including + unsafe-to-copy chunks which were dropped before) and eliminates the + repositioning of vpAg and sTER in pngtest.png by changing pngtest.png + (so the chunks are where libpng would put them). + Added "tunknown" test and corrected a logic error in png_handle_unknown() + when SAVE support is absent. Moved the shell test scripts for + contrib/libtests from the libpng top directory to contrib/libtests. + png_handle_unknown() must always read or skip the chunk, if + SAVE_UNKNOWN_CHUNKS is turned off *and* the application does not set + a user callback an unknown chunk will not be read, leading to a read + error, which was revealed by the "tunknown" test. + Cleaned up and corrected ICC profile handling. + contrib/libtests/makepng: corrected 'rgb' and 'gray' cases. profile_error + messages could be truncated; made a correct buffer size calculation and + adjusted pngerror.c appropriately. png_icc_check_* checking improved; + changed the functions to receive the correct color type of the PNG on read + or write and check that it matches the color space of the profile (despite + what the comments said before, there is danger in assuming the app will + cope correctly with an RGB profile on a grayscale image and, since it + violates the PNG spec, allowing it is certain to produce inconsistent + app behavior and might even cause app crashes.) Check that profiles + contain the tags needed to process the PNG (tags all required by the ICC + spec). Removed unused PNG_STATIC from pngpriv.h. + +Version 1.6.0beta29 [September 4, 2012] + Fixed the simplified API example programs to add the *colormap parameter + to several of he API and improved the error message if the version field + is not set. + Added contrib/examples/* to the *.zip and *.7z distributions. + Updated simplified API synopses and description of the png_image structure + in the manual. + Made makepng and pngtest produce identical PNGs, add "--relaxed" option + to pngtest. The "--relaxed" option turns off the benign errors that are + enabled by default in pre-RC builds. makepng can now write ICC profiles + where the length has not been extended to a multiple of 4, and pngtest + now intercepts all libpng errors, allowing the previously-introduced + "--strict test" on no warnings to actually work. + Improved ICC profile handling including cHRM chunk generation and fixed + Cygwin+MSVC build errors. The ICC profile handling now includes more + checking. Several errors that caused rejection of the profile are now + handled with a warning in such a way that the invalid profiles will be + read by default in release (but not pre-RC) builds but will not be + written by default. The easy part of handling the cHRM chunk is written, + where the ICC profile contains the required data. The more difficult + part plus guessing a gAMA value requires code to pass selected RGB values + through the profile. + +Version 1.6.0beta30 [October 24, 2012] + Changed ICC profile matrix/vector types to not depend on array type rules. + By the ANSI-C standard the new types should be identical to the previous + versions, and all known versions of gcc tested with the previous versions + except for GCC-4.2.1 work with this version. The change makes the ANSI-C + rule that const applied to an array of elements applies instead to the + elements in the array moot by explicitly applying const to the base + elements of the png_icc_matrix and png_icc_vector types. The accidental + (harmless) 'const' previously applied to the parameters of two of the + functions have also been removed. + Added a work around for GCC 4.2 optimization bug. + Marked the broken (bad white point) original HP sRGB profiles correctly and + correct comments. + Added -DZ_SOLO to contrib/pngminim/*/makefile to work with zlib-1.2.7 + Use /MDd for vstudio debug builds. Also added pngunkown to the vstudio + builds, fixed build errors and corrected a minor exit code error in + pngvalid if the 'touch' file name is invalid. + Add updated WARNING file to projects/vstudio from libpng 1.5/vstudio + Fixed build when using #define PNG_NO_READ_GAMMA in png_do_compose() in + pngrtran.c (Domani Hannes). + +Version 1.6.0beta31 [November 1, 2012] + Undid the erroneous change to vstudio/pngvalid build in libpng-1.6.0beta30. + Made pngvalid so that it will build outside the libpng source tree. + Made builds -DPNG_NO_READ_GAMMA compile (the unit tests still fail). + Made PNG_NO_READ_GAMMA switch off interfaces that depend on READ_GAMMA. + Prior to 1.6.0 switching off READ_GAMMA did unpredictable things to the + interfaces that use it (specifically, png_do_background in 1.4 would + simply display composite for grayscale images but do composition + with the incorrect arithmetic for color ones). In 1.6 the semantic + of -DPNG_NO_READ_GAMMA is changed to simply disable any interface that + depends on it; this obliges people who set it to consider whether they + really want it off if they happen to use any of the interfaces in + question (typically most users who disable it won't). + Fixed GUIDs in projects/vstudio. Some were duplicated or missing, + resulting in VS2010 having to update the files. + Removed non-working ICC profile support code that was mostly added to + libpng-1.6.0beta29 and beta30. There was too much code for too little + gain; implementing full ICC color correction may be desireable but is left + up to applications. + +Version 1.6.0beta32 [November 25, 2012] + Fixed an intermittent SEGV in pngstest due to an uninitialized array element. + Added the ability for contrib/libtests/makepng.c to make a PNG with just one + color. This is useful for debugging pngstest color inaccuracy reports. + Fixed error checking in the simplified write API (Olaf van der Spek) + Made png_user_version_check() ok to use with libpng version 1.10.x and later. + +Version 1.6.0beta33 [December 15, 2012] + Fixed typo in png.c (PNG_SET_CHUNK_MALLOC_MAX should be PNG_CHUNK_MALLOC_MAX) + that causes the MALLOC_MAX limit not to work (John Bowler) + Change png_warning() to png_app_error() in pngwrite.c and comment the + fall-through condition. + Change png_warning() to png_app_warning() in png_write_tRNS(). + Rearranged the ARM-NEON optimizations: Isolated the machine specific code + to the hardware subdirectory and added comments to pngrutil.c so that + implementors of other optimizations know what to do. + Fixed cases of unquoted DESTDIR in Makefile.am + Rebuilt Makefile.in, etc., with autoconf-2.69 and automake-1.12.5. + +Version 1.6.0beta34 [December 19, 2012] + Cleaned up whitespace in the synopsis portion of the manpage "libpng.3" + Disassembled the version number in scripts/options.awk (necessary for + building on SunOs). + +Version 1.6.0beta35 [December 23, 2012] + Made default Zlib compression settings be configurable. This adds #defines to + pnglibconf.h to control the defaults. + Fixed Windows build issues, enabled ARM compilation. Various warnings issued + by earlier versions of GCC fixed for Cygwin and Min/GW (which both use old + GCCs.) ARM support is enabled by default in zlib.props (unsupported by + Microsoft) and ARM compilation is made possible by deleting the check for + x86. The test programs cannot be run because they are not signed. + +Version 1.6.0beta36 [January 2, 2013] + Discontinued distributing libpng-1.x.x.tar.bz2. + Discontinued distributing libpng-1.7.0-1.6.0-diff.txt and similar. + Rebuilt configure with autoconf-2.69 (inadvertently not done in beta33) + Fixed 'make distcheck' on SUN OS - libpng.so was not being removed + +Version 1.6.0beta37 [January 10, 2013] + Fixed conceivable but difficult to repro overflow. Also added two test + programs to generate and test a PNG which should have the problem. + +Version 1.6.0beta39 [January 19, 2013] + Again corrected attempt at overflow detection in png_set_unknown_chunks() + (CVE-2013-7353). Added overflow detection in png_set_sPLT() and + png_set_text_2() (CVE-2013-7354). + +Version 1.6.0beta40 [January 20, 2013] + Use consistent handling of overflows in text, sPLT and unknown png_set_* APIs + +Version 1.6.0rc01 [January 26, 2013] + No changes. + +Version 1.6.0rc02 [February 4, 2013] + Added png_get_palette_max() function. + +Version 1.6.0rc03 [February 5, 2013] + Fixed the png_get_palette_max API. + +Version 1.6.0rc04 [February 7, 2013] + Turn serial tests back on (recently turned off by autotools upgrade). + +Version 1.6.0rc05 [February 8, 2013] + Update manual about png_get_palette_max(). + +Version 1.6.0rc06 [February 9, 2013] + Fixed missing dependency in --prefix builds The intermediate + internal 'prefix.h' file can only be generated correctly after + pnglibconf.h, however the dependency was not in Makefile.am. The + symptoms are unpredictable depending on the order make chooses to + build pngprefix.h and pnglibconf.h, often the error goes unnoticed + because there is a system pnglibconf.h to use instead. + +Version 1.6.0rc07 [February 10, 2013] + Enclosed the new png_get_palette_max in #ifdef PNG_GET_PALETTE_MAX_SUPPORTED + block, and revised pnglibconf.h and pnglibconf.h.prebuilt accordingly. + +Version 1.6.0rc08 [February 10, 2013] + Fix typo in png.h #ifdef + +Version 1.6.0 [February 14, 2013] + No changes. + +Version 1.6.1beta01 [February 16, 2013] + Made symbol prefixing work with the ARM neon optimizations. Also allow + pngpriv.h to be included for preprocessor definitions only, so it can + be used in non-C/C++ files. Back ported from libpng 1.7. + Made sRGB check numbers consistent. + Ported libpng 1.5 options.awk/dfn file handling to 1.6, fixed one bug. + Removed cc -E workround, corrected png_get_palette_max API Tested on + SUN OS cc 5.9, which demonstrates the tokenization problem previously + avoided by using /lib/cpp. Since all .dfn output is now protected in + double quotes unless it is to be macro substituted the fix should + work everywhere. + Enabled parallel tests - back ported from libpng-1.7. + scripts/pnglibconf.dfa formatting improvements back ported from libpng17. + Fixed a race condition in the creation of the build 'scripts' directory + while building with a parallel make. + Use approved/supported Android method to check for NEON, use Linux/POSIX + 1003.1 API to check /proc/self/auxv avoiding buffer allocation and other + library calls (ported from libpng15). + +Version 1.6.1beta02 [February 19, 2013] + Use parentheses more consistently in "#if defined(MACRO)" tests. + Folded long lines. + Reenabled code to allow zero length PLTE chunks for MNG. + +Version 1.6.1beta03 [February 22, 2013] + Fixed ALIGNED_MEMORY support. + Allow run-time ARM NEON checking to be disabled. A new configure option: + --enable-arm-neon=always will stop the run-time checks. New checks + within arm/arm_init.c will cause the code not to be compiled unless + __ARM_NEON__ is set. This should make it fail safe (if someone asks + for it on then the build will fail if it can't be done.) + Updated the INSTALL document. + +Version 1.6.1beta04 [February 27, 2013] + Revised INSTALL to recommend using CPPFLAGS instead of INCLUDES. + Revised scripts/makefile.freebsd to respect ZLIBLIB and ZLIBINC. + Revised scripts/dfn.awk to work with the buggy MSYS awk that has trouble + with CRLF line endings. + +Version 1.6.1beta05 [March 1, 2013] + Avoid a possible memory leak in contrib/gregbook/readpng.c + +Version 1.6.1beta06 [March 4, 2013] + Better documentation of unknown handling API interactions. + Corrected Android builds and corrected libpng.vers with symbol + prefixing. This adds an API to set optimization options externally, + providing an alternative and general solution for the non-portable + run-time tests used by the ARM Neon code. It also makes those tests + compile and link on Android. + The order of settings vs options in pnglibconf.h is reversed to allow + settings to depend on options and options can now set (or override) the + defaults for settings. + +Version 1.6.1beta07 [March 7, 2013] + Corrected simplified API default gamma for color-mapped output, added + a flag to change default. In 1.6.0 when the simplified API was used + to produce color-mapped output from an input image with no gamma + information the gamma assumed for the input could be different from + that assumed for non-color-mapped output. In particular 16-bit depth + input files were assumed to be sRGB encoded, whereas in the 'direct' + case they were assumed to have linear data. This was an error. The + fix makes the simplified API treat all input files the same way and + adds a new flag to the png_image::flags member to allow the + application/user to specify that 16-bit files contain sRGB data + rather than the default linear. + Fixed bugs in the pngpixel and makepng test programs. + +Version 1.6.1beta08 [March 7, 2013] + Fixed CMakelists.txt to allow building a single variant of the library + (Claudio Bley): + Introduced a PNG_LIB_TARGETS variable that lists all activated library + targets. It is an error if this variable ends up empty, ie. you have + to build at least one library variant. + Made the *_COPY targets only depend on library targets actually being build. + Use PNG_LIB_TARGETS to unify a code path. + Changed the CREATE_SYMLINK macro to expect the full path to a file as the + first argument. When symlinking the filename component of that path is + determined and used as the link target. + Use copy_if_different in the CREATE_SYMLINK macro. + +Version 1.6.1beta09 [March 13, 2013] + Eliminated two warnings from the Intel C compiler. The warnings are + technically valid, although a reasonable treatment of division would + show it to be incorrect. + +Version 1.6.1rc01 [March 21, 2013] + No changes. + +Version 1.6.1 [March 28, 2013] + No changes. + +Version 1.6.2beta01 [April 14, 2013] + Updated documentation of 1.5.x to 1.6.x changes in iCCP chunk handling. + Fixed incorrect warning of excess deflate data. End condition - the + warning would be produced if the end of the deflate stream wasn't read + in the last row. The warning is harmless. + Corrected the test on user transform changes on read. It was in the + png_set of the transform function, but that doesn't matter unless the + transform function changes the rowbuf size, and that is only valid if + transform_info is called. + Corrected a misplaced closing bracket in contrib/libtests/pngvalid.c + (Flavio Medeiros). + Corrected length written to uncompressed iTXt chunks (Samuli Suominen). + Bug was introduced in libpng-1.6.0. + +Version 1.6.2rc01 [April 18, 2013] + Added contrib/tools/fixitxt.c, to repair the erroneous iTXt chunk length + written by libpng-1.6.0 and 1.6.1. + Disallow storing sRGB information when the sRGB is not supported. + +Version 1.6.2rc02 [April 18, 2013] + Merge pngtest.c with libpng-1.7.0 + +Version 1.6.2rc03 [April 22, 2013] + Trivial spelling cleanup. + +Version 1.6.2rc04 and 1.6.2rc05 [omitted] + +Version 1.6.2rc06 [April 24, 2013] + Reverted to version 1.6.2rc03. Recent changes to arm/neon support + have been ported to libpng-1.7.0beta09 and will reappear in version + 1.6.3beta01. + +Version 1.6.2 [April 25, 2013] + No changes. + +Version 1.6.3beta01 [April 25, 2013] + Revised stack marking in arm/filter_neon.S and configure.ac. + Ensure that NEON filter stuff is completely disabled when switched 'off'. + Previously the ARM NEON specific files were still built if the option + was switched 'off' as opposed to being explicitly disabled. + +Version 1.6.3beta02 [April 26, 2013] + Test for 'arm*' not just 'arm' in the host_cpu configure variable. + Rebuilt the configure scripts. + +Version 1.6.3beta03 [April 30, 2013] + Expanded manual paragraph about writing private chunks, particularly + the need to call png_set_keep_unknown_chunks() when writing them. + Avoid dereferencing NULL pointer possibly returned from + png_create_write_struct() (Andrew Church). + +Version 1.6.3beta05 [May 9, 2013] + Calculate our own zlib windowBits when decoding rather than trusting the + CMF bytes in the PNG datastream. + Added an option to force maximum window size for inflating, which was + the behavior of libpng15 and earlier. + Added png-fix-itxt and png-fix-too-far-back to the built programs and + removed warnings from the source code and timepng that are revealed as + a result. + Detect wrong libpng versions linked to png-fix-too-far-back, which currently + only works with libpng versions that can be made to reliably fail when + the deflate data contains an out-of-window reference. This means only + 1.6 and later. + Fixed gnu issues: g++ needs a static_cast, gcc 4.4.7 has a broken warning + message which it is easier to work round than ignore. + Updated contrib/pngminus/pnm2png.c (Paul Stewart): + Check for EOF + Ignore "#" delimited comments in input file to pnm2png.c. + Fixed whitespace handling + Added a call to png_set_packing() + Initialize dimension values so if sscanf fails at least we have known + invalid values. + Attempt to detect configuration issues with png-fix-too-far-back, which + requires both the correct libpng and the correct zlib to function + correctly. + Check ZLIB_VERNUM for mismatches, enclose #error in quotes + Added information in the documentation about problems with and fixes for + the bad CRC and bad iTXt chunk situations. + +Version 1.6.3beta06 [May 12, 2013] + Allow contrib/pngminus/pnm2png.c to compile without WRITE_INVERT and + WRITE_PACK supported (writes error message that it can't read P1 or + P4 PBM files). + Improved png-fix-too-far-back usage message, added --suffix option. + Revised contrib/pngminim/*/makefile to generate pnglibconf.h with the + right zlib header files. + Separated CPPFLAGS and CFLAGS in contrib/pngminim/*/makefile + +Version 1.6.3beta07 [June 8, 2013] + Removed a redundant test in png_set_IHDR(). + Added set(CMAKE_CONFIGURATION_TYPES ...) to CMakeLists.txt (Andrew Hundt) + Deleted set(CMAKE_BUILD_TYPE) block from CMakeLists.txt + Enclose the prototypes for the simplified write API in + #ifdef PNG_STDIO_SUPPORTED/#endif + Make ARM NEON support work at compile time (not just configure time). + This moves the test on __ARM_NEON__ into pngconf.h to avoid issues when + using a compiler that compiles for multiple architectures at one time. + Removed PNG_FILTER_OPTIMIZATIONS and PNG_ARM_NEON_SUPPORTED from + pnglibconf.h, allowing more of the decisions to be made internally + (pngpriv.h) during the compile. Without this, symbol prefixing is broken + under certain circumstances on ARM platforms. Now only the API parts of + the optimizations ('check' vs 'api') are exposed in the public header files + except that the new setting PNG_ARM_NEON_OPT documents how libpng makes the + decision about whether or not to use the optimizations. + Protect symbol prefixing against CC/CPPFLAGS/CFLAGS useage. + Previous iOS/Xcode fixes for the ARM NEON optimizations moved the test + on __ARM_NEON__ from configure time to compile time. This breaks symbol + prefixing because the definition of the special png_init_filter_functions + call was hidden at configure time if the relevant compiler arguments are + passed in CFLAGS as opposed to CC. This change attempts to avoid all + the confusion that would result by declaring the init function even when + it is not used, so that it will always get prefixed. + +Version 1.6.3beta08 [June 18, 2013] + Revised libpng.3 so that "doclifter" can process it. + +Version 1.6.3beta09 [June 27, 2013] + Revised example.c to illustrate use of PNG_DEFAULT_sRGB and PNG_GAMMA_MAC_18 + as parameters for png_set_gamma(). These have been available since + libpng-1.5.4. + Renamed contrib/tools/png-fix-too-far-back.c to pngfix.c and revised it + to check all compressed chunks known to libpng. + +Version 1.6.3beta10 [July 5, 2013] + Updated documentation to show default behavior of benign errors correctly. + Only compile ARM code when PNG_READ_SUPPORTED is defined. + Fixed undefined behavior in contrib/tools/pngfix.c and added new strip + option. pngfix relied on undefined behavior and even a simple change from + gcc to g++ caused it to fail. The new strip option 'unsafe' has been + implemented and is the default if --max is given. Option names have + been clarified, with --strip=transform now stripping the bKGD chunk, + which was stripped previously with --strip=unused. + Added all documented chunk types to pngpriv.h + Unified pngfix.c source with libpng17. + +Version 1.6.3rc01 [July 11, 2013] + No changes. + +Version 1.6.3 [July 18, 2013] + Revised manual about changes in iTXt chunk handling made in libpng-1.6.0. + Added "/* SAFE */" comments in pngrutil.c and pngrtran.c where warnings + may be erroneously issued by code-checking applications. + +Version 1.6.4beta01 [August 21, 2013] + Added information about png_set_options() to the manual. + Delay calling png_init_filter_functions() until a row with nonzero filter + is found. + +Version 1.6.4beta02 [August 30, 2013] + Fixed inconsistent conditional compilation of png_chunk_unknown_handling() + prototype, definition, and usage. Made it depend on + PNG_HANDLE_AS_UNKNOWN_SUPPORTED everywhere. + +Version 1.6.4rc01 [September 5, 2013] + No changes. + +Version 1.6.4 [September 12, 2013] + No changes. + +Version 1.6.5 [September 14, 2013] + Removed two stray lines of code from arm/arm_init.c. + +Version 1.6.6 [September 16, 2013] + Removed two stray lines of code from arm/arm_init.c, again. + +Version 1.6.7beta01 [September 30, 2013] + Revised unknown chunk code to correct several bugs in the NO_SAVE_/NO_WRITE + combination + Allow HANDLE_AS_UNKNOWN to work when other options are configured off. Also + fixed the pngminim makefiles to work when $(MAKEFLAGS) contains stuff + which terminates the make options (as by default in recent versions of + Gentoo). + Avoid up-cast warnings in pngvalid.c. On ARM the alignment requirements of + png_modifier are greater than that of png_store and as a consequence + compilation of pngvalid.c results in a warning about increased alignment + requirements because of the bare cast to (png_modifier*). The code is safe, + because the pointer is known to point to a stack allocated png_modifier, + but this change avoids the warning. + Fixed default behavior of ARM_NEON_API. If the ARM NEON API option was + compiled without the CHECK option it defaulted to on, not off. + Check user callback behavior in pngunknown.c. Previous versions compiled + if SAVE_UNKNOWN was not available but did nothing since the callback + was never implemented. + Merged pngunknown.c with 1.7 version and back ported 1.7 improvements/fixes + +Version 1.6.7beta02 [October 12, 2013] + Made changes for compatibility with automake 1.14: + 1) Added the 'compile' program to the list of programs that must be cleaned + in autogen.sh + 2) Added 'subdir-objects' which causes .c files in sub-directories to be + compiled such that the corresponding .o files are also in the + sub-directory. This is because automake 1.14 warns that the + current behavior of compiling to the top level directory may be removed + in the future. + 3) Updated dependencies on pnglibconf.h to match the new .o locations and + added all the files in contrib/libtests and contrib/tools that depend + on pnglibconf.h + 4) Added 'BUILD_SOURCES = pnglibconf.h'; this is the automake recommended + way of handling the dependencies of sources that are machine generated; + unfortunately it only works if the user does 'make all' or 'make check', + so the dependencies (3) are still required. + Cleaned up (char*) casts of zlib messages. The latest version of the Intel C + compiler complains about casting a string literal as (char*), so copied the + treatment of z_const from the library code into pngfix.c + Simplified error message code in pngunknown. The simplification has the + useful side effect of avoiding a bogus warning generated by the latest + version of the Intel C compiler (it objects to + condition ? string-literal : string-literal). + Make autogen.sh work with automake 1.13 as well as 1.14. Do this by always + removing the 1.14 'compile' script but never checking for it. + +Version 1.6.7beta03 [October 19, 2013] + Added ARMv8 support (James Yu <james.yu at linaro.org>). Added file + arm/filter_neon_intrinsics.c; enable with -mfpu=neon. + Revised pngvalid to generate size images with as many filters as it can + manage, limited by the number of rows. + Cleaned up ARM NEON compilation handling. The tests are now in pngpriv.h + and detect the broken GCC compilers. + +Version 1.6.7beta04 [October 26, 2013] + Allow clang derived from older GCC versions to use ARM intrinsics. This + causes all clang builds that use -mfpu=neon to use the intrinsics code, + not the assembler code. This has only been tested on iOS 7. It may be + necessary to exclude some earlier clang versions but this seems unlikely. + Changed NEON implementation selection mechanism. This allows assembler + or intrinsics to be turned on at compile time during the build by defining + PNG_ARM_NEON_IMPLEMENTATION to the correct value (2 or 1). This macro + is undefined by default and the build type is selected in pngpriv.h. + +Version 1.6.7rc01 [November 2, 2013] + No changes. + +Version 1.6.7rc02 [November 7, 2013] + Fixed #include in filter_neon_intrinsics.c and ctype macros. The ctype char + checking macros take an unsigned char argument, not a signed char. + +Version 1.6.7 [November 14, 2013] + No changes. + +Version 1.6.8beta01 [November 24, 2013] + Moved prototype for png_handle_unknown() in pngpriv.h outside of + the #ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED/#endif block. + Added "-Wall" to CFLAGS in contrib/pngminim/*/makefile + Conditionally compile some unused functions reported by -Wall in + pngminim. + Fixed 'minimal' builds. Various obviously useful minimal configurations + don't build because of missing contrib/libtests test programs and + overly complex dependencies in scripts/pnglibconf.dfa. This change + adds contrib/conftest/*.dfa files that can be used in automatic build + scripts to ensure that these configurations continue to build. + Enabled WRITE_INVERT and WRITE_PACK in contrib/pngminim/encoder. + Fixed pngvalid 'fail' function declaration on the Intel C Compiler. + This reverts to the previous 'static' implementation and works round + the 'unused static function' warning by using PNG_UNUSED(). + +Version 1.6.8beta02 [November 30, 2013] + Removed or marked PNG_UNUSED some harmless "dead assignments" reported + by clang scan-build. + Changed tabs to 3 spaces in png_debug macros and changed '"%s"m' + to '"%s" m' to improve portability among compilers. + Changed png_free_default() to free() in pngtest.c + +Version 1.6.8rc01 [December 12, 2013] + Tidied up pngfix inits and fixed pngtest no-write builds. + +Version 1.6.8rc02 [December 14, 2013] + Handle zero-length PLTE chunk or NULL palette with png_error() + instead of png_chunk_report(), which by default issues a warning + rather than an error, leading to later reading from a NULL pointer + (png_ptr->palette) in png_do_expand_palette(). This is CVE-2013-6954 + and VU#650142. Libpng-1.6.1 through 1.6.7 are vulnerable. + Libpng-1.6.0 and earlier do not have this bug. + +Version 1.6.8 [December 19, 2013] + No changes. + +Version 1.6.9beta01 [December 26, 2013] + Bookkeeping: Moved functions around (no changes). Moved transform + function definitions before the place where they are called so that + they can be made static. Move the intrapixel functions and the + grayscale palette builder out of the png?tran.c files. The latter + isn't a transform function and is no longer used internally, and the + former MNG specific functions are better placed in pngread/pngwrite.c + Made transform implementation functions static. This makes the internal + functions called by png_do_{read|write}_transformations static.

On read invert alpha, processing + occurred after shift processing, which causes the final values to be + outside the range that should be produced by the shift. Reversing the + order on read makes the two transforms work together correctly and mirrors + the order used on write. + Do not read invalid sBIT chunks. Previously libpng only checked sBIT + values on write, so a malicious PNG writer could therefore cause + the read code to return an invalid sBIT chunk, which might lead to + application errors or crashes. Such chunks are now skipped (with + chunk_benign_error). + Make png_read_png() and png_write_png() prototypes in png.h depend + upon PNG_READ_SUPPORTED and PNG_WRITE_SUPPORTED. + Support builds with unsupported PNG_TRANSFORM_* values. All of the + PNG_TRANSFORM_* values are always defined in png.h and, because they + are used for both read and write in some cases, it is not reliable + to #if out ones that are totally unsupported. This change adds error + detection in png_read_image() and png_write_image() to do a + png_app_error() if the app requests something that cannot be done + and it adds corresponding code to pngimage.c to handle such options + by not attempting to test them. + +Version 1.6.10beta02 [February 23, 2014] + Moved redefines of png_error(), png_warning(), png_chunk_error(), + and png_chunk_warning() from pngpriv.h to png.h to make them visible + to libpng-calling applications. + Moved OS dependent code from arm/arm_init.c, to allow the included + implementation of the ARM NEON discovery function to be set at + build-time and provide sample implementations from the current code in the + contrib/arm-neon subdirectory. The __linux__ code has also been changed to + compile and link on Android by using /proc/cpuinfo, and the old linux code + is in contrib/arm-neon/linux-auxv.c.

It is + * difficult to be sure that the calculation is stable for real world values + * and it is certain that it becomes unstable where the end points are close + * together. + * + * So this code uses the perhaps slightly less optimal but more + * understandable and totally obvious approach of calculating color-scale. + * + * This algorithm depends on the precision in white-scale and that is + * (1/white-y), so we can immediately see that as white-y approaches 0 the + * accuracy inherent in the cHRM chunk drops off substantially. + * + * libpng arithmetic: a simple inversion of the above equations + * ------------------------------------------------------------ + * + * white_scale = 1/white-y + * white-X = white-x * white-scale + * white-Y = 1.0 + * white-Z = (1 - white-x - white-y) * white_scale + * + * white-C = red-C + green-C + blue-C + * = red-c*red-scale + green-c*green-scale + blue-c*blue-scale + * + * This gives us three equations in (red-scale,green-scale,blue-scale) where + * all the coefficients are now known: + * + * red-x*red-scale + green-x*green-scale + blue-x*blue-scale + * = white-x/white-y + * red-y*red-scale + green-y*green-scale + blue-y*blue-scale = 1 + * red-z*red-scale + green-z*green-scale + blue-z*blue-scale + * = (1 - white-x - white-y)/white-y + * + * In the last equation color-z is (1 - color-x - color-y) so we can add all + * three equations together to get an alternative third: + * + * red-scale + green-scale + blue-scale = 1/white-y = white-scale + * + * So now we have a Cramer's rule solution where the determinants are just + * 3x3 - far more tractible. Unfortunately 3x3 determinants still involve + * multiplication of three coefficients so we can't guarantee to avoid + * overflow in the libpng fixed point representation. Using Cramer's rule in + * floating point is probably a good choice here, but it's not an option for + * fixed point. Instead proceed to simplify the first two equations by + * eliminating what is likely to be the largest value, blue-scale: + * + * blue-scale = white-scale - red-scale - green-scale + * + * Hence: + * + * (red-x - blue-x)*red-scale + (green-x - blue-x)*green-scale = + * (white-x - blue-x)*white-scale + * + * (red-y - blue-y)*red-scale + (green-y - blue-y)*green-scale = + * 1 - blue-y*white-scale + * + * And now we can trivially solve for (red-scale,green-scale): + * + * green-scale = + * (white-x - blue-x)*white-scale - (red-x - blue-x)*red-scale + * ----------------------------------------------------------- + * green-x - blue-x + * + * red-scale = + * 1 - blue-y*white-scale - (green-y - blue-y) * green-scale + * --------------------------------------------------------- + * red-y - blue-y + * + * Hence: + * + * red-scale = + * ( (green-x - blue-x) * (white-y - blue-y) - + * (green-y - blue-y) * (white-x - blue-x) ) / white-y + * ------------------------------------------------------------------------- + * (green-x - blue-x)*(red-y - blue-y)-(green-y - blue-y)*(red-x - blue-x) + * + * green-scale = + * ( (red-y - blue-y) * (white-x - blue-x) - + * (red-x - blue-x) * (white-y - blue-y) ) / white-y + * ------------------------------------------------------------------------- + * (green-x - blue-x)*(red-y - blue-y)-(green-y - blue-y)*(red-x - blue-x) + * + * Accuracy: + * The input values have 5 decimal digits of accuracy. The values are all in + * the range 0 < value < 1, so simple products are in the same range but may + * need up to 10 decimal digits to preserve the original precision and avoid + * underflow. Because we are using a 32-bit signed representation we cannot + * match this; the best is a little over 9 decimal digits, less than 10. + * + * The approach used here is to preserve the maximum precision within the + * signed representation. Because the red-scale calculation above uses the + * difference between two products of values that must be in the range -1..+1 + * it is sufficient to divide the product by 7; ceil(100,000/32767*2). The + * factor is irrelevant in the calculation because it is applied to both + * numerator and denominator. + * + * Note that the values of the differences of the products of the + * chromaticities in the above equations tend to be small, for example for + * the sRGB chromaticities they are: + * + * red numerator: -0.04751 + * green numerator: -0.08788 + * denominator: -0.2241 (without white-y multiplication) + * + * The resultant Y coefficients from the chromaticities of some widely used + * color space definitions are (to 15 decimal places): + * + * sRGB + * 0.212639005871510 0.715168678767756 0.072192315360734 + * Kodak ProPhoto + * 0.288071128229293 0.711843217810102 0.000085653960605 + * Adobe RGB + * 0.297344975250536 0.627363566255466 0.075291458493998 + * Adobe Wide Gamut RGB + * 0.258728243040113 0.724682314948566 0.016589442011321 + */ + /* By the argument, above overflow should be impossible here.
