This - disallows image width/height/format that *might* overflow. This is - a quiet API change that limits in-memory image size (uncompressed) to - less than 4GByte and image row size (stride) to less than 2GByte. - Revised workaround for false-positive Coverity issue in pngvalid.c. - Only use exit(77) in configure builds. - Updated CMakeLists.txt, added supporting scripts/gen*.cmake.in - and test.cmake.in (Roger Leigh). - Relaxed limit checks on gamma values in pngrtran.c. As suggested in - the comments gamma values outside the range currently permitted - by png_set_alpha_mode are useful for HDR data encoding. These values - are already permitted by png_set_gamma so it is reasonable caution to - extend the png_set_alpha_mode range as HDR imaging systems are starting - to emerge. - Added a common-law trademark notice and export control information - to the LICENSE file, png.h, and the man page. - Restored "& 0xff" in png_save_uint_16() and png_save_uint_32() that - were accidentally removed from libpng-1.6.17. - Changed PNG_INFO_cHNK and PNG_FREE_cHNK from 0xnnnn to 0xnnnnU in png.h - (Robert C. Seacord). - Removed dubious "#if INT_MAX" test from png.h that was added to - libpng-1.6.19 (John Bowler). - Add ${INCLUDES} in scripts/genout.cmake.in (Bug report by Nixon Kwok). - Updated LICENSE to say files in the contrib directory are not - necessarily under the libpng license, and that some makefiles have - other copyright owners. - Added INTEL-SSE2 support (Mike Klein and Matt Sarett, Google, Inc.). - Made contrib/libtests/timepng more robust. The code no longer gives - up/fails on invalid PNG data, it just skips it (with error messages). - The code no longer fails on PNG files with data beyond IEND. Options - exist to use png_read_png (reading the whole image, not by row) and, in - that case, to apply any of the supported transforms. This makes for - more realistic testing; the decoded data actually gets used in a - meaningful fashion (John Bowler). - Fixed some misleading indentation (Krishnaraj Bhat). - Force GCC compilation to C89 if needed (Dagobert Michelsen). - SSE filter speed improvements for bpp=3: - memcpy-free implementations of load3() / store3(). - call load3() only when needed at the end of a scanline. - Added PNG_FAST_FILTERS macro (defined as - PNG_FILTER_NONE|PNG_FILTER_SUB|PNG_FILTER_UP). - Various fixes for contrib/libtests/timepng.c - Fixed typo (missing underscore) in #define PNG_READ_16_TO_8_SUPPORTED - (Bug report by Y.Ohashik). - Quieted two Coverity issues in contrib/libtests/timepng.c. - Fixed issues with scripts/genout.cmake.in (David Capello, Nixon Kwok): - Added support to use multiple directories in ZLIBINCDIR variable, - Fixed CMAKE_C_FLAGS with multiple values when genout is compiled on MSVC, - Fixed pnglibconf.c compilation on OS X including the sysroot path. - Check for CLOCK_PROCESS_CPUTIME_ID when building /contrib/libtests/timepng. - Check for the presence of clock_gettime() in configure.ac and Makefile.am. + libpng-1.6.23-README.txt + libpng-1.6.23-LICENSE.txt + libpng-1.6.23-*.asc (armored detached GPG signatures) + +Changes since the last public release (1.6.22): + + Stop a potential memory leak in png_set_tRNS() (Bug report by Ted Ying). + Fixed the progressive reader to handle empty first IDAT chunk properly + (patch by Timothy Nikkel).
