Cocoa® Programming

Summary

This chapter described modifying the graphics context used for vector drawing to produce powerful and complex effects. The techniques for fast rectangle and point drawing enable applications such as scatter charts and control points. The optimization techniques presented can be used to speed up almost any Cocoa application. A lot of details of vector drawing have been covered, but techniques for drawing images and text have not yet been covered. Chapter 14, “Custom Views and Graphics Part III,” dives into descriptions of Cocoa image and text support. Image manipulation and sophisticated text rendering are two of Cocoa’s strongest attributes.
