Examples of ae.sun.java2d.SunGraphics2D

ae.sun.java2d.SunGraphics2D
This is a the master Graphics2D superclass for all of the Sun Graphics implementations. This class relies on subclasses to manage the various device information, but provides an overall general framework for performing all of the requests in the Graphics and Graphics2D APIs. @author Jim Graham
