Trimage image compressor – 1.0.5

A cross-platform tool for losslessly optimizing PNG and JPG files.

Trimage is a cross-platform GUI and command-line interface to optimize image files via optipng, pngcrush, advpng and jpegoptim, depending on the filetype (currently, PNG and JPG files are supported). It was inspired by imageoptim. All image files are losslessy compressed on the highest available compression levels. Trimage gives you various input functions to fit your own workflow: A regular file dialog, dragging and dropping and various command line options.

Not good to simply sys.exit() from any random part of code (can leave things in a mess) - consider context managers for handling compression, so as to keep operations atomic and/or rollback-able - add a recursive option on the command-line for use with -d - make -f accept a list of files - make the current verbose be "normal", and make -verbose print the commandline app prints as well - find a way to specify the version once for everywhere - notification area drag/drop widget -> probably need gtk for gnome todo else - figure out how to make mac and win versions (someone else :) <- via gui2exe =========================================== later versions: animate compressing.gif allow selection/deletion of rows from table (and subsequently the imagelist) punypng api? http://www.gracepointafterfive.com/punypng/api imagemagick/graphicsmagick? always on top option intelligently recompress, i.e. go through the list of files, recompress each until no more gains are seen (and a sensible number-of-tries limit isn't exceeded), and flag that file as fully-optimised. Repeat for each file in the list, until all are done. Saves pointlessly trying to optimise files. Consider the case of a directory of 100 files, already optimised once. Recompressing maximally compresses 90. Recompressing again would currently try to recompress all 100, when only 10 would be worthy of trying to compress further.
