TODO list for libpng
|
||||
--------------------
|
||||
|
||||
* Fix all defects (duh!)
|
||||
* Better C++ wrapper / full C++ implementation (?)
|
||||
* Fix the problems with C++ and 'extern "C"'.
|
||||
* cHRM transformation.
|
||||
* Palette creation.
|
||||
* "grayscale->palette" transformation and "palette->grayscale" detection.
|
||||
* Improved dithering.
|
||||
* Multi-lingual error and warning message support.
|
||||
* Complete sRGB transformation. (Currently it simply uses gamma=0.45455.)
|
||||
* Man pages for function calls.
|
||||
* Better documentation.
|
||||
* Better filter selection
|
||||
(e.g., counting huffman bits/precompression; filter inertia; filter costs).
|
||||
* Histogram creation.
|
||||
* Text conversion between different code pages (e.g., Latin-1 -> Mac).
|
||||
* Avoid building gamma tables whenever possible.
|
||||
* Greater precision in changing to linear gamma for compositing against
|
||||
background, and in doing rgb-to-gray transformations.
|
||||
* Investigate pre-incremented loop counters and other loop constructions.
|
||||
* Interpolated method of handling interlacing.
|
||||
* More validations for libpng transformations.
