Overview

QuickDraw is the legacy 2D drawing engine for Macintosh computers. QuickDraw provides routines for drawing, manipulating, and displaying graphic objects such as lines, arcs, rectangles, ovals, regions, and bitmap images. Carbon supports most of the classic QuickDraw programming interface.

Note: QuickDraw has been deprecated for deployment targets Mac OS X version 10.4 and later. The replacement API is Quartz 2D. Because of the fundamental differences in the imaging models and design goals between QuickDraw and Quartz, there is no direct correspondence between QuickDraw and Quartz concepts and interfaces. For certain purposes, some QuickDraw functions may still be needed during a transition period; nevertheless, most of them have been deprecated to express the overriding goal of eliminating the use of QuickDraw in the future.
