As a start on + this, minimize the use of png_error(), replacing them with + png_warning(); return(0); or similar. +Palette creation. +Add "grayscale->palette" transformation and "palette->grayscale" detection. +Improved 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?). +Histogram creation. +Text conversion between different code pages (Latin-1 -> Mac and DOS). +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. +Extend pngvalid.c to validate more of the libpng transformations. +Refactor preprocessor conditionals to compile entire statements + +*/ |
