All Implemented Interfaces:

javax.accessibility.Accessible, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable

public class ImagePanel

extends java.awt.Canvas

implements java.io.Serializable

This class represents the canvas which draws an image. So instead of drawing an image, you add it like a component. This class is supposed to be used internally, so no further documentation will be provided.
