QuickDraw GX

QuickDraw GX was intended as a replacement for the QuickDraw (QD ) 2D graphics engine and Printing Manager of the Mac OS " Classic".

Description

Although GX based on the same basic geometry and metrics such as the original QuickDraw engine that the underlying platform has been re-specified as resolution- independent, object-oriented, and buffered system and implemented that performing common tasks for programmers very simplified. In addition, GX were various commands to represent Bezier curves (which Quickdraw missing) added and introduced TrueType font as a basic system.

Although GX undoubtedly solved many of the problems of QuickDraw, most users of QuickDraw had developed at the time of the appearance of GX their own proprietary solutions for it. GX also suffered from a number of incompatibilities in conjunction with existing programs, especially with those who brought their own extensions to bypass the shortcomings of QuickDraw. This, and the resistance of some well-known application providers, and in particular the PostScript developer Adobe, as well as the lack of communication of the benefits and reasons for GX from Apple had the effect that this technique led a shadowy existence. After GX was scrapped due to the buyout of NeXT and quartz took over the role of the preferred graphics engine, but found many of the features of GX in a modified form in today's graphics layer of Mac OS X again.
