Jari sdesc: "PNG image optimising utility" ldesc: "pngquant is a command-line conversion utility to quantize and dither truecolor PNG images, especially those with a full alpha channel, down to 8-bit (or smaller) RGBA-palette PNGs. Such images are usually two to four times smaller than the full 32-bit versions, and partial transparency is preserved quite nicely. This makes pngquant especially useful both for Web sites and for PlayStation 2 development, where one of the texture formats is RGBA-palette-based (though not PNG-compressed). This is the same technique used for many of the images on the Miscellaneous Transparent PNGs page (http://www.libpng.org/pub/png/pngs-img.html), and the results are often indistinguishable from the original, truecolor PNG images." category: Graphics requires: cygwin a) manual wget \ http://cygwin.cante.net/pngquant/pngquant-1.0-1-src.tar.bz2 \ http://cygwin.cante.net/pngquant/pngquant-1.0-1.tar.bz2 \ http://cygwin.cante.net/pngquant/setup.hint \ b) automated gpg --keyserver wwwkeys.pgp.net --recv-keys 955A92D8 mkdir pngquant ; cd pngquant rm -f get.sh get.sh.sig wget http://cygwin.cante.net/pngquant/get.sh \ http://cygwin.cante.net/pngquant/get.sh.sig && gpg --verify get.sh.sig get.sh && sh get.sh -- Welcome to FOSS revolution: we fix and modify until it shines
