description Rotating image data ninety degrees is disclosed. In one embodiment of the invention, the computerized system includes an operating system providing a graphics interface library, and a graphics interface buffer maintained by the graphics interface library. The graphics interface buffer contains image data comprising a first screen image. The system also includes a graphics device driver that implements a method to rotate an area within the image data by dividing the area into a plurality of square pixel regions, rotating each of the squares, and writing the squares to an image data buffer comprising a display buffer maintained by the graphics device driver.
