SYSTEM AND METHODS FOR MANAGING COMPOSITION OF SURFACES

摘要

A system and a method for compositing graphics on a computing device are provided. The computing device includes one or more hardware layers. The method includes determining if the number of surfaces to be displayed by the computing device is more than the number of the hardware layers. If so, two or more of the surfaces are combined to form one or more pseudo surfaces. The combined number of the pseudo surfaces and the remaining ones of the surfaces is equal to or less than the number of the one or more hardware layers. This allows for each of the pseudo surfaces or the remaining ones of the surfaces to be assigned to separate hardware layers. The computational cost for combining the surfaces is also considered during the process.
