Graphics Tricks from the Command Line
An anonymous reader writes "There's nothing quite like command-line tools for handling large batches of tasks, and image manipulations are no exception. Web developers and administrators will appreciate the ability to handle large numbers of files easily, either at the command line or in scripts. This article presents the ImageMagick suite, a Linux toolkit for sizing, rotating, converting, and otherwise manipulating images, in a huge number of formats, whether one or a hundred at a time."
This seems like it could be useful for easy and fast (not always smart) integration into Web Applications. Its far easier to make a call to a command line image manipulation software than to call a library and do all the work yourself. Though I suppose with calling an application for the web, there may be security problems.
