Abstract
A method for rendering static graphics in a mobile device in applications such as map applications. Panning increments are received for panning a previously rendered frame to a panned frame. A rendering region is defined based on the panning increments and the rendering region is expanded to provide an expanded region. At least one of a candidate polygon, candidate line segment, and polyline is clipped to the expanded region to obtain one or more clipped portions of the at least one of the candidate polygon, candidate line segment and candidate polyline contained within the expanded region. The one or more clipped portions of the candidate polygon, candidate line segment and candidate polyline, are rendered and portion of the previously rendered frame is copied to provide the panned frame.
