Gmagick

Gmagick is a PHP extension to create, modify, and obtain meta-information of images using the GraphicsMagick API. GraphicsMagick prides itself as the swiss army knife of image processing. It works with over 88 major formats including DPX, GIF, JPEG, JPEG-2000, PNG, PDF, PNM, and TIFF. Gmagick consists of a main Gmagick class, a GmagickDraw class that is in effect a drawing wand, and a GmagickPixel class of which instances represent a single pixel of an image (color, opacity).
