ABSTRACT:
A method and apparatus to stretch video images in a graphics controller chip of a computer system. The graphics controller chip fetches four pixel data comprising two pixel data each from a first scan line and a second scan line of a source video image, and generates a set of additional pixels in a rectangular area defined by the four pixels. The graphics controller chip stores the pixels of rectangular portions in a display memory, and displays the pixel data of the stretched video image in a scan line order.
