Using a PanWindow

The Pan Window is a small window which will display a scaled view of a bitmap, which is also being displayed in the Main Control's window at a size that would require scrolling. The Pan Window will maintain the image’s aspect ratio. In the Pan Window, a colored Pan Rect will be displayed to indicate the portion of the image currently being displayed in the main window. When a user clicks inside the Pan Window and moves the mouse, while holding down the button, the Pan Rect will move with the mouse pointer.
