TODO - list of things to do for libpng:
|
|
|
|
Final bug fixes.
|
|
Finish work on the no-floating-point version (including gamma compensation)
|
|
Better C++ wrapper/full C++ implementation?
|
|
Fix problem with C++ and EXTERN "C".
|
|
cHRM transformation.
|
|
Remove setjmp/longjmp usage in favor of returning error codes.
|
|
Add "grayscale->palette" transformation and "palette->grayscale" detection.
|
|
Improved dithering.
|
|
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).
|
|
Build gamma tables using fixed point (and do away with floating point entirely).
|
|
Avoid building gamma tables whenever possible.
|
|
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.
