public class ImageCanvas
extends java.awt.Canvas

A simple output widget for a RenderedImage. ImageCanvas subclasses java.awt.Canvas, and can be used in any context that calls for a Canvas. It monitors resize and update events and automatically requests tiles from its source on demand. Any displayed area outside the image is displayed in grey.

There is currently no policy regarding what sorts of widgets, if any, will be part of JAI.

Due to the limitations of BufferedImage, only TYPE_BYTE of band 1, 2, 3, 4, and TYPE_USHORT of band 1, 2, 3 images can be displayed using this widget.

This class has been deprecated. The source code has been moved to the samples/widget directory. These widgets are no longer supported.
