<h2>Description</h2>
<p>The Cocoa CG arc demo shows how to draw both aliased and anti-aliased arcs. The graphics drawing functions are contained within the MyQuartzView.m file in the drawRect: method. This sample is based on a Cocoa CG Shell project that simply shows a window with an embedded NSView subclass called MyQuartzView to hold the custom drawing. While the project itself is Cocoa based, the CG code contained within the drawRect: method is straightforward, easily reused, and fully applicable to Carbon as well. Requirements: Project Builder, Mac OS X Keywords: Cocoa CG Core Graphics Quartz 2D arc</p>
