  java.awt.Component

      java.awt.Container

          javax.swing.JComponent

              swpatho.ap1.editor.images.Panner

All Implemented Interfaces:

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

public final class Panner

extends javax.swing.JComponent

implements java.awt.event.MouseListener, java.awt.event.MouseMotionListener

An output widget used for panning. Panner 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.

Constructor Detail

Panner

public Panner()

Default constructor

Panner

public Panner(javax.swing.JComponent item,
              PlanarImage image,

Constructs a Panner to display a scaled PlanarImage. Swing object to be controlled.

Parameters:

image - a PlanarImage to be displayed. Max width or height for scaled image.

Panner

public Panner(int panner_width,
              int panner_height)

Constructs a Panner with no image

Method Detail
