2018-07-15Release libpng version 1.6.35Cosmin Truta
2018-06-17[libpng16] Replace the remaining uses of png_size_t with size_tCosmin Truta
In v1.6.0, size_t became a required type. It should be used consistently. To maintain backwards compatibility, png_size_t is still maintained in deprecated form.

2013-11-22[libpng16] Fixed 'minimal' builds. Various obviously useful minimalGlenn Randers-Pehrson
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.

2011-12-24[libpng16] Implemented 'restrict' for png_info and png_struct.John Bowler
Added new "png_structrp" typedef. 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.
2011-12-22[libpng16] bump version to 1.6.0beta04Glenn Randers-Pehrson
2011-12-22[libpng16] Start-up code size improvements, error handler flexibility. TheseJohn Bowler
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.

2010-08-18[devel]Made all API functions that have const arguments and constant stringGlenn Randers-Pehrson
literal pointers declare them (John Bowler). Many APIs did not change their arguments but were not declared using PNG_CONST. This change corrects this. In a few cases APIs that return constant string literal pointers have also been changed to declare this. Unlike the argument change this may require app changes; however the results could never be written to (the app would crash on some platforms where strings are not writable), so this seems advisable.

2010-07-29[devel]Glenn Randers-Pehrson
Fixed point APIs are now supported throughout (no missing APIs). Internal fixed point arithmetic support exists for all internal floating point operations. sCAL validates the floating point strings it is passed. Safe, albeit rudimentary, Watcom support is provided by PNG_API_RULE==2 Two new APIs exist to get the number of passes without turning on the PNG_INTERLACE transform and to get the number of rows in the current pass. A new test program, pngvalid.c, validates the gamma code. Errors in the 16 bit gamma correction (overflows) have been corrected. cHRM chunk testing is done consistently (previously the floating point API bypassed it, because the test really didn't work on FP, now the test is performed on the actual values to be stored in the PNG file so it works in the FP case too.) Most floating point APIs now simply call the fixed point APIs after converting the values to the fixed point form used in the PNG file. The standard headers no longer include zlib.h, which is currently only required for pngstruct.h and can therefore be internal. (Patches by John Bowler)
