              Res.ImageDisplay

All Implemented Interfaces:

java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener

public class ImageDisplay
extends javax.swing.JComponent
implements java.awt.event.MouseListener, java.awt.event.MouseMotionListener

An output widget for a PlanarImage. ImageDisplay subclasses javax.swing.JComponent, and can be used in any context that calls for a JComponent. It monitors resize and update events and automatically requests tiles from its source on demand.

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.

Constructs an ImageDisplay to display a PlanarImage.

Parameters:

source - a PlanarImage to be displayed.

ImageDisplay

public ImageDisplay(int width,
                    int height)

Constructs an ImageDisplay of fixed size (no image)

Parameters:

width - - display width

height - - display height

Method Detail

set

public void set(javax.media.jai.PlanarImage im)

Changes the source image to a new PlanarImage.

set
