Abstract
An image displayed on a digital display such as a flat panel display is rotated while the same image is displayed on a cathode ray tube display in unrotated form. When image rotation is selected, the read address sequence into a frame buffer may be reversed and the bit read sequence may be reversed. Thus a frame of panel pixel data stored within the frame buffer of an external video memory may be scanned onto a flat panel to display a rotated image.
