1/* 2TODO - list of things to do for libpng: 3 4Final bug fixes. 5Better C++ wrapper/full C++ implementation? 6Fix problem with C++ and EXTERN "C". 7cHRM transformation. 8Remove setjmp/longjmp usage in favor of returning error codes. 9Palette creation. 10Add "grayscale->palette" transformation and "palette->grayscale" detection. 11Improved dithering. 12Multi-lingual error and warning message support. 13Complete sRGB transformation (presently it simply uses gamma=0.45455). 14Make profile checking optional via a png_set_something() call. 15Man pages for function calls. 16Better documentation. 17Better filter selection 18 (counting huffman bits/precompression? filter inertia? filter costs?). 19Histogram creation. 20Text conversion between different code pages (Latin-1 -> Mac and DOS). 21Avoid building gamma tables whenever possible. 22Use greater precision when changing to linear gamma for compositing against 23 background and doing rgb-to-gray transformation. 24Investigate pre-incremented loop counters and other loop constructions. 25Add interpolated method of handling interlacing. 26Switch to the simpler zlib (zlib/libpng) license if legally possible. 27Extend pngvalid.c to validate more of the libpng transformations. 28 29*/ 30
