OptiPNG - TODO list
===================
- Text chunk optimization: smart selection between tEXt and zTXt.
Similarly for iTXt.
- More file recovery features.
- Optimization of an entire directory, with and without subdirectory
recursion:
optipng dir/
optipng -r dir/
Currently it is possible to optimize an entire directory as:
optipng dir/*.png
provided that file globbing works, either at the shell level (Unix)
or in the program (linked with wildargs.obj on Windows).
- Support for reading external image formats: PNM, BMP, GIF, ...
- Support for conversion to a desired bit depth and color type:
optipng -b16 -c6 ...
- Support for chunk-level editing:
optipng -add text <keyword> <file> ... # add chunk
optipng -upd text <keyword> <file> ... # update (add/replace) chunk
optipng -del time ... # delete chunk
optipng -del visual ... # delete tRNS, gAMA, sRGB, ...
optipng -del nonvisual ... # delete all but tRNS, gAMA ...
optipng -del textual ... # delete tEXt, zTXt, iTXt, tIME
optipng -del nontextual ... # delete all but tEXt, zTXt ...
optipng -del gif ... # delete gIFg, gIFt, gIFx
optipng -del private ... # delete all private chunks
optipng -del all ... # delete all ancillary chunks
- Timer:
optipng -timer ...
It may be enough to show the timer under the -v option, without
needing a new -timer option.
- A nice GUI.
