Viewer and Converter for Images
ImageMagick is a robust collection of tools and libraries to read, write, and manipulate an image in many image formats, including popular formats like TIFF, JPEG, PNG, PDF, PhotoCD, and GIF. With ImageMagick, you can create images dynamically, making it suitable for Web applications. You can also resize, rotate, sharpen, color-reduce, or add special effects to an image and save your completed work in many different image formats. Image processing operations are available from the command line as well as through C, C++, and PERL-based programming interfaces.
