public class CanvasJAI

extends Canvas

An extension of java.awt.Canvas for use with JAI. CanvasJAI automatically returns an instance of GraphicsJAI from its getGraphics() method. This guarantees that the update(Graphics g) and paint(Graphics g) methods will receive a GraphicsJAI instance for accelerated rendering of JAI images.

In circumstances where it is not possible to use CanvasJAI, a similar effect may be obtained by manually calling GraphicsJAI.createGraphicsJAI() to "wrap" a Graphics2D object.
