Almost all of the libpng building configuration - is moved from pngconf.h to pngpriv.h, but PNG_DLL_EXPORT remains in - pngconf.h, though, so that it is colocated with the import definition (it - is no longer used anywhere in the installed headers). The VStudio project - definitions have been cleaned up: "_USRDLL" has been removed from the - static library builds (this was incorrect), and PNG_USE_DLL has been added - to pngvalid to test the functionality (pngtest does not supply it, - deliberately). The spurious "_EXPORTS" has been removed from the - libpng build (all these errors were a result of copy/paste between project - configurations.) - Added new types and internal functions for CIE RGB end point handling to - pngpriv.h (functions yet to be implemented). - Ensure the CMAKE_LIBRARY_OUTPUT_DIRECTORY is set in CMakeLists.txt - (Clifford Yap) - Fixes to rgb_to_gray and cHRM XYZ APIs (John Bowler): - The rgb_to_gray code had errors when combined with gamma correction. - Some pixels were treated as true grey when they weren't and such pixels - and true grey ones were not gamma corrected (the original value of the - red component was used instead). APIs to get and set cHRM using color - space end points have been added and the rgb_to_gray code that defaults - based on cHRM, and the divide-by-zero bug in png_handle_cHRM (CERT - VU#477046, CVE-2011-3328, introduced in 1.5.4) have been corrected. - A considerable number of tests has been added to pngvalid for the - rgb_to_gray transform. - Arithmetic errors in rgb_to_gray whereby the calculated gray value was - truncated to the bit depth rather than rounded have been fixed except in - the 8-bit non-gamma-corrected case (where consistency seems more important - than correctness.) The code still has considerable inaccuracies in the - 8-bit case because 8-bit linear arithmetic is used. - Added "$(ARCH)" option to makefile.darwin - Added SunOS support to configure.ac and Makefile.am - Changed png_chunk_benign_error() to png_warning() in png.c, in - png_XYZ_from_xy_checked(). - Fixed 64-bit compilation errors (gcc). The errors fixed relate - to conditions where types that are 32 bits in the GCC 32-bit - world (uLong and png_size_t) become 64 bits in the 64-bit - world.

This would probably have led to a + crash. The pngmem.c implementation of png_malloc() included a cast + to png_size_t which would fail on large allocations on 16-bit systems. + Fix for the preprocessor of the Intel C compiler. The preprocessor + splits adjacent @ signs with a space; this changes the 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. + 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. + Added versioning to pnglibconf.h comments. + 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. + Added run-time detection of NEON support. + 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 compose and rgb to gray (on palette). + 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.
