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