TODO - list of things to do for libpng:
|
|
|
|
|
|
|
|
|
|
Final bug fixes.
|
|
|
|
|
Better C++ wrapper/full C++ implementation?
|
|
|
|
|
Fix problem with C++ and EXTERN "C".
|
|
|
|
|
cHRM transformation.
|
2016-09-08 17:37:15 +10:00
|
|
|
Remove setjmp/longjmp usage in favor of returning error codes. As a start on
|
|
|
|
|
this, minimize the use of png_error(), replacing them with
|
2017-10-17 14:55:57 -05:00
|
|
|
png_warning(); return(0); or similar.
|
2016-09-08 17:37:15 +10:00
|
|
|
Palette creation.
|
2012-09-19 11:15:01 -04:00
|
|
|
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).
|
2013-03-09 16:19:11 -05:00
|
|
|
Avoid building gamma tables whenever possible.
|
2012-09-19 11:15:01 -04:00
|
|
|
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.
|
2013-03-09 16:19:11 -05:00
|
|
|
Add interpolated method of handling interlacing.
|
|
|
|
|
Extend pngvalid.c to validate more of the libpng transformations.
|
2017-10-17 14:55:57 -05:00
|
|
|
Refactor preprocessor conditionals to compile entire statements
