The GUI Pan Control allows the visible portion of an image displayed in the ImGearPageView Class control to be moved by dragging the mouse around in the image. Optionally, a floating window can be used to display the complete image, scaled to fit within the floating window. By dragging the mouse within this floating window, the image in the ImGearPageView Class control is repositioned. The portion of the image that is visible in the ImGearPageView Class control is displayed within the floating window in reverse video. Refer to the ImGearPan Class.
