ABSTRACT:
Pixel-mode frame buffer interpretation is used to concurrently display graphical and image data in a common resolution. Pixel data in a frame buffer can be of varying types. A mask is stored in video memory and defines the "state" of each pixel. The pixel state determines how a video controller is to interpret the pixel data for that pixel and thus allows the concurrent display of graphics data and image data.
