# Introduction

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 important formats like DPX, GIF, JPEG, JPEG-2000, PNG, PDF, PNM, and TIFF.

Gmagick consists of a main Gmagick class, a GmagickDraw class which is in effect a drawing wand and a GmagickPixel class of which instances represent a single pixel of an image (color, opacity).
