Improve setjmp/longjmp usage or remove it in favor of returning error codes. -High-level API for reading images. Add "grayscale->palette" transformation and "palette->grayscale" detection. -Color to gray transformation. -Improved dithering. +Improved quantizing and 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?). -Optional palette (sPLT) creation. Histogram creation. Text conversion between different code pages (Latin-1 -> Mac and DOS). -Improve API by hiding the info_ptr. +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. + +*/
