public class ScrollingImagePanel

extends ScrollPane

implements AdjustmentListener, ComponentListener, MouseListener, MouseMotionListener

An extension of java.awt.Panel that contains an ImageCanvas and vertical and horizontal scrollbars. The origin of the ImageCanvas is set according to the value of the scrollbars. Additionally, the origin may be changed by dragging the mouse. The window cursor will be changed to Cursor.MOVE_CURSOR for the duration of the drag.

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.
