A page description language incorporated into the Macintosh operating system, which is a useful part of many Macintosh applications. QuickDraw, although rarely used for high-quality output to an imagesetter, is quick and adequate for daily office tasks, and many laser printers are driven by QuickDraw commands. For high-quality output, however, QuickDraw files are converted (by QuickDraw itself) to PostScript format. Color QuickDraw extensions allow for the support of 32-Bit color.
Like PostScript, QuickDraw essentially converts page elements to mathematical formulas that describe lines and curves, and is used for two-dimensional text or images. Apple's latest version of QuickDraw—called QuickDraw 3D—allows for the rendering of three-dimensional images.
