* [libpng16] bump version to 1.6.0beta07Glenn Randers-Pehrson2012-01-241-9/+9
|
* [libpng16] Added color-map support to simplified API.John Bowler2012-01-231-117/+113
| | | | | This is an initial version for review; the documentation has not yet been updated.
* [libpng16] Add palette support to the simplified APIs. This commitJohn Bowler2012-01-161-55/+186
| | | | | changes some of the macro definitions in png.h, app code may need corresponding changes.

* [libpng16] Add 'const' to png_structrp arguments of png_set_*() APIs.John Bowler2011-12-281-56/+60
| | | | | | Because these APIs store to the png_info they can take a png_const_structrp now that the error routines also accept one of these.
* [libpng16] Implemented 'restrict' for png_info and png_struct.John Bowler2011-12-241-282/+304
| | | | | | | 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.
* [libpng16] Enabled png_get_sCAL_fixed() if floating point APIs are enabled.John Bowler2011-12-241-6/+7
| | | | | | 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.
* [libpng16] Began a manual section about libpng15 to libpng16 differences.Glenn Randers-Pehrson2011-12-221-2/+2

* [libpng16] Start-up code size improvements, error handler flexibility. TheseJohn Bowler2011-12-221-201/+177
| | | | | | | | | | | | | | | | | 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.

| | | | | | | | 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.
