Abstract
Image data is generated and stored for prioritized image levels of a composite graphics display along with certain control and blending data. To composite data levels for a display, individual picture elements (pixels) are generated in accordance with level priority, control signal indications of enablement, control signal indications of color and alpha control signals (object position and transparency). Accordingly, object data from plural levels is selected or blended on a pixel-by-pixel basis to accomplish a desired composite display.
