Graphics Engines

����The Graphics Engine includes elements at all three of the lowest levels, from physically displaying things on a monitor to providing high level graphics routines such as fonts and animated sprites.

QuickDraw

���� Operating systems that support QuickDraw: Macintosh (QuickDraw and QuickDraw GX), Rhapsody (QuickDraw GX), and Macintosh OS X (Enhanced QuickDraw)

���� �Graphics are an important part of every Macintosh application. All graphic operations on the Macintosh are performed by QuickDraw. To draw something on the screen, you�ll often call one of the other parts of the [Macintosh User Interface] Toolbox, but it will in turn call QuickDraw. You�ll also call QuickDraw directly, usually to draw inside a window, or just to set up constructs like rectangles that you�ll need when making other Toolbox calls. QuickDraw�s underlying concepts, like those of the Resource Manager, are important for you to understand.
�����Graphics include text as well as pictures. To draw text, QuickDraw calls the Font Manager, which does the background work necessary to make a variety of character fonts available in various sizes and styles. Unless your application includes a font menu, you need to know only a minimal amount about the Font Manager.� �Inside Macintosh, Volume I, page I-11^b4b
