Wesley Recursively searches a directory path for image files (JPEG, GIF, PNG) and applies lossless compression to files in-place. This can be particularly handy for optimizing images in an existing codebase, especially when you are geared for working from the Linux or Mac command-line. This script uses techniques described in this article about the use of jpegtran: http://www.phpied.com/installing-jpegtran-mac-unix-linux/ and used by the smush.it tool described here: http://developer.yahoo.com/yslow/smushit/faq.html Wesley makes use of gifsicle, ImageMagick, jpegtran, and pngcrush to optimize images. You should make an attempt to ensure that each of these has been installed on your system prior to running this script. If you are missing any of these, however, Wesley will still run but will skip any optimizations for which the applicable software is not available. In other words, if you don't have jpegtran installed, Wesley will skip JPEG optimizations. ------------------- PACKAGES ------------------- You're going to want to check the server you're working on to see which of these packages you may already have, or need to install. You can still run Wesley if you're missing one or more of these packages. Fewer optimizations will be made, however. If you're working on a Mac, try using Fink to install these packages before compiling on your own from source. jpegtran http://sylvana.net/jpegcrop/jpegtran/ gifsicle http://www.lcdf.org/gifsicle/ pngcrush http://pmt.sourceforge.net/pngcrush/ ImageMagick http://www.imagemagick.org/ ------------------- USAGE ------------------- Recursively optimize all images within a directory: wesley.pl directory_path Optimize a single image: wesley.pl filename ------------------- MORE INFO ------------------- Original author: Mike Brittain Homepage: http://www.mikebrittain.com/blog/wesley/
