An efficient method of compositing planes onto a target surface using a computing device with graphics processing capability is disclosed. The method includes partitioning the target surface, on which planes are composited, into partitions. Each one of the partitions contains connected pixels to be formed by compositing an identical subset of the planes to be composited. Each partition is associated with a corresponding subset of the planes. Each partition and its corresponding set of associated planes are then provided to a graphics processor for composition, using exemplary software components including an application programming interface, a library and device driver software. An image is formed on the target surface by compositing each partition. Using the disclosed method, a single pass through stages of the graphics pipeline for the graphics processor is sufficient to composite multiple planes to form an image on the target surface.
