TODO - list of things to do for libpng:
1995-07-20 03:43:20 -04:00
1998-12-29 12:47:59 -05:00
Final bug fixes.
2000-05-06 15:09:57 -04:00
Improve API by hiding the png_struct and png_info structs.
2000-02-05 00:40:16 -05:00
Finish work on the no-floating-point version (including gamma compensation)
1998-12-29 12:47:59 -05:00
Better C++ wrapper/full C++ implementation?
2000-02-05 00:40:16 -05:00
Fix problem with C++ and EXTERN "C".
1998-12-29 12:47:59 -05:00
cHRM transformation.
Improve setjmp/longjmp usage or remove it in favor of returning error codes.
Add "grayscale->palette" transformation and "palette->grayscale" detection.
Improved quantizing and dithering.
1998-12-29 12:47:59 -05:00
Multi-lingual error and warning message support.
Complete sRGB transformation (presently it simply uses gamma=0.45455).
Man pages for function calls.
Better documentation.
Better filter selection
(counting huffman bits/precompression? filter inertia? filter costs?).
Histogram creation.
Text conversion between different code pages (Latin-1 -> Mac and DOS).
2000-12-23 15:27:39 -05:00
Build gamma tables using fixed point (and do away with floating point entirely).
Avoid building gamma tables whenever possible.
2000-12-23 15:27:39 -05:00
Use greater precision when changing to linear gamma for compositing against
background and doing rgb-to-gray transformation.
Investigate pre-incremented loop counters and other loop constructions.
Add interpolated method of handling interlacing.
Provide for conditional compilation of 16-bit support (except for the
initial stripping down to 8-bits when reading a 16-bit PNG datastream).
Switch to the simpler zlib (zlib/libpng) license if legally possible.
