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 Add "grayscale->palette" transformation and "palette->grayscale" detection. 10 Improved dithering. 11 Multi-lingual error and warning message support. 12 Complete sRGB transformation (presently it simply uses gamma=0.45455). 13 Make profile checking optional via a png_set_something() call. 14 Man pages for function calls. 15 Better documentation. 16 Better filter selection 17 (counting huffman bits/precompression? filter inertia? filter costs?). 18 Histogram creation. 19 Text conversion between different code pages (Latin-1 -> Mac and DOS). 20 Avoid building gamma tables whenever possible. 21 Use greater precision when changing to linear gamma for compositing against 22 background and doing rgb-to-gray transformation. 23 Investigate pre-incremented loop counters and other loop constructions. 24 Add interpolated method of handling interlacing. 25 Switch to the simpler zlib (zlib/libpng) license if legally possible. 26 Extend pngvalid.c to validate more of the libpng transformations. 27 28 */ 29
