Abstract
An apparatus and method used to perform image rendering is capable of producing complex, high resolution images for a continuous synchronous raster image output device, such as a laser printer or a video display, using a minimum of random access memory. High level graphics instructions defining an image to be displayed or printed are provided by a processor executing an applications program. These instructions are interpreted to generate a set of graphics orders that are subsequently processed to create a bitmap image for output to a display or printer device. The graphics order processing system is independent of the central processor and thereby significantly reduces the central processor's image output overhead.
