PHP extensions for ImageMagick functionality. 　　Using this extension allows PHP to have the same functionality as ImageMagick. ImageMagick is a powerful, stable and free toolset and development package that can be used to read, write, and process image files in more than 185 basic formats, including popular TIFF, JPEG, GIF, PNG, PDF, and PHOTOCD formats. With ImageMagick, you can dynamically generate images based on the needs of your Web application, and you can resize, rotate, sharpen, subtract, or add effects to a (or a group of) images and save the results of the operation in the same format or other format.
