Abstract

An operating system for manipulating the orientation of an output image of a data processing system provides operating system support to rotate an image output to a device driver at rendering time for printing in portrait or landscape mode and for displaying the image in increments of 90 decree rotations. A user or system sets a rotation for all output images sent to the peripheral device, regardless of what application provides the image, and the operating system performs the rotation on all output images sent to the particular output device.
