public class ScrollableImage
extends JPanel
implements Scrollable, MouseMotionListener, MouseListener, ImageObserver

A scrollable panel. This class also implements the ability to select an area with the mouse. The selected area will be displayed with a red outline, and then the selected area is communicated back to the main window to tell it that the user wants to zoom in on a section of the panel.
