ABSTRACT:
The present invention relates generally to computer graphics, and more specifically to methods of, and systems for, configuring, controlling and accessing multiple hardware graphics layers that are used to compose a single video display. One aspect of the invention is broadly defined as follows: in a computer environment including a software application and an operating system running on a computer, the computer including a graphics card and a video display, the graphics card being operable to render images to the video display, the improvement comprising: the operating system including a universal application programming interface (API) which supports hardware layers on graphics cards; the operating system being operable to: receive draw events via the universal API; determine what hardware layers are available on the graphics card, and what their parameters are; and respond to draw requests from the software application by rendering the draw requests selectively to any of the available hardware layers on the graphics card; whereby the computer environment allows software applications to exploit available hardware layers on the graphics card.
