ISTR that the standard PNG tarball includes a number of tools, one of which is a program that, when fed a given PNG image, will try and find the best options for that image by brute-force, i.e. it just sits in a loop re-compressing the image over and over with different options until it finds the best combination. It's a long time since I used it - it did work, but didn't reduce the files by all that much (though I am told that with the right image the savings can be dramatic) and it took a *very* long time to run... Computers have got faster in the meantime too, of course! > png is just a wrapper for different compression algorithms. Most png images > use jpeg compression internally. Is that true? I don't think that is true - PNG is lossless and IIRC uses ZLIB internally. The JPEG format is (usually) lossy, and the lossless variant doesn't compress well. _______________________________________________ fltk-dev mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk-dev
