Patterns

A pattern is a sequence of drawing operations that is repeatedly painted to a graphics context. You can use patterns in the same way as you use colors. When you paint using a pattern, Quartz divides the page into a set of pattern cells, with each cell the size of the pattern image, and draws each cell using a callback you provide. Figure 6-1 shows a pattern drawn to a window graphics context. Patterns are available in Mac OS X v10.1 and later.
