Abstract:
A method of static graphics rendering in a mobile device. Panning increments are received for panning a previously rendered frame to a panned frame. A rendering region is then determined based on the panning increments. A candidate line segment or polyline is then clipped to create clipped line segments contained within the rendering region. The clipped line segments can then be rendered, and a portion of the previously rendered frame can be copied, to provide the panned frame.
