ABSTRACT:
A transform engine is configured to rotate, and/or rotate and translate, one or more polygons in response to screen orientation. Thus, when texture data obtained from a pre-rotated image is applied to a rotated polygon from an image, a rotated version of the image is generated in response to screen orientation. Alternatively, a user may select a rotation to re-orient the image to a screen view position. The rotated image may also be shifted to maintain conformance with edge rules.
