They - have been combined with PNG_SET_USER_LIMITS_SUPPORTED (resolves - bug report by Andrew Church). - Fixed rgb_to_gray checks and added tRNS checks to pngvalid.c. This - fixes some arithmetic errors that caused some tests to fail on - some 32-bit platforms (Bug reports by Peter Breitenlohner [i686] - and Petr Gajdos [i586]). - Suppressed some warnings from the Borland C++ 5.5.1/5.82 compiler - (Bug report by Viktor Szaka'ts). - Replaced "unexpected" with an integer (0xabadca11) in pngset.c - where a long was expected, to avoid a compiler warning when PNG_DEBUG > 1. - Added contrib/examples/simpleover.c, to demonstrate how to handle - alpha compositing of multiple images, using the "simplified API" - and an example PNG generation tool, contrib/examples/genpng.c - (John Bowler). - PNG_RELEASE_BUILD replaces tests where the code depended on the build base - type and can be defined on the command line, allowing testing in beta - builds (John Bowler). - Avoid Coverity issue 80858 (REVERSE NULL) in pngtest.c - Avoid a harmless potential integer overflow in png_XYZ_from_xy() (Bug - report from Christopher Ferris). - Backport filter selection code from libpng-1.7.0beta51, to combine - sub_row, up_row, avg_row, and paeth_row into try_row and tst_row. - Changed png_voidcast(), etc., to voidcast(), etc., in contrib/tools/pngfix.c - to avoid confusion with the libpng private macros. - Fixed old cut&paste bug in the weighted filter selection code in - pngwutil.c, introduced in libpng-0.95, March 1997. - Removed WRITE_WEIGHTED_FILTERED code, to save a few kbytes of the - compiled library size. It never worked properly and as far as we can - tell, no one uses it. The png_set_filter_heuristics() and - png_set_filter_heuristics_fixed() APIs are retained but deprecated - and do nothing. - Quieted some Coverity issues in pngfix.c, png-fix-itxt.c, pngvalid.c, - pngstest.c, and pngimage.c. Most seem harmless, but png-fix-itxt - would only work with iTXt chunks with length 255 or less. - Removed non-working progressive reader 'skip' function. This - function has apparently never been used. It was implemented - to support back-door modification of png_struct in libpng-1.4.x - but (because it does nothing and cannot do anything) was apparently - never tested (John Bowler). - Fixed cexcept.h in which GCC 5 now reports that one of the auto - variables in the Try macro needs to be volatile to prevent value - being lost over the setjmp (John Bowler). - Added #ifdef's to contrib/examples programs so people don't try - to compile them without the minimum required support enabled - (suggested by Flavio Medeiros). - Eliminated the final two Coverity defects (insecure temporary file - handling in contrib/libtests/pngstest.c; possible overflow of - unsigned char in contrib/tools/png-fix-itxt.c). To use the "secure" - file handling, define PNG_USE_MKSTEMP, otherwise "tmpfile()" will - be used. - Removed some unused WEIGHTED_FILTER macros from pngstruct.h - Replaced arbitrary use of 'extern' with #define PNG_LINKAGE_*. To - preserve API compatibility, the new defines all default to "extern" - (requested by Jan Nijtmans). - Belatedly added Mans Rullgard and James Yu to the list of Contributing - Authors.
