Summary:A selected portion of a graphical image is displayed in a window on a monitor. A scroll box on one side of the window is provided for changing the displayed portion of the image responsive to the movement of the scroll box. The scroll box includes end portions, or handles, which may be dragged to resize the scroll box. This has the effect of changing the scale or magnification of the displayed portion of the image. In the preferred embodiment, the invention is implemented in a Windows TM computer environment. Resizable scroll boxes, as described, may be provided for both horizontal and vertical dimensions of the display window. The described user interface has the advantage of providing an integrated control for both selecting a portion of the graphical image for viewing and selecting the scale of the viewed portion in an intuitive manner.
