The size and position of the inner region relative to the outer region is changed in response to input commands. The size of the inner region is decreased when an input command is entered selecting the inner region. The size of thean outer region representing the original image and an inner region positioned within the outer region, wherein a position of the inner region within the outer region represents the portion of the original image being displayed within the image display window. A size of the inner region relative to the outer region represents the magnification of the original image being displayed within the image display window. The graphical user interface further comprises a magnification factor displayed within the inner region which numerically represents the magnification of the original image being displayed within the image display window.
In yet another aspect of the present invention, a method of controlling magnification of, and portion of, an original image displayed within an image display window includes the steps of displaying a zoom
