1TODO - list of things to do for libpng: 2 3* Fix all defects (duh!) 4* Better C++ wrapper / full C++ implementation (?) 5* Fix the problems with C++ and 'extern "C"'. 6* cHRM transformation. 7* Palette creation. 8* "grayscale->palette" transformation and "palette->grayscale" detection. 9* Improved dithering. 10* Multi-lingual error and warning message support. 11* Complete sRGB transformation. (Currently it simply uses gamma=0.45455.) 12* Man pages for function calls. 13* Better documentation. 14* Better filter selection 15 (e.g., counting huffman bits/precompression; filter inertia; filter costs). 16* Histogram creation. 17* Text conversion between different code pages (e.g., Latin-1 -> Mac). 18* Avoid building gamma tables whenever possible. 19* Greater precision in changing to linear gamma for compositing against 20 background, and in doing rgb-to-gray transformations. 21* Investigate pre-incremented loop counters and other loop constructions. 22* Interpolated method of handling interlacing. 23* More validations for libpng transformations. 24
