ImageMagick is a free open-source program for creating and manipulating images in more than 68 formats (including GIF, JPEG, TIFF, PhotoCD, PDF, and PNG). It runs on many popular operating systems including Linux, Unix, Windows, Macintosh, VMS, and OS2. You can manipulate image files directly from the command line, or access the different manipulation methods through your favorite Perl, C, C++, or Java development environment.
