ABSTRACT:
A method and system for rapidly transmitting multicolor or gray scale display data having multiple bits per pixel to a display device is provided. In a preferred embodiment, the method and system constitutes a software facility. The facility first encodes the image into multiple bit per pixel raster data. The multiple bit per pixel raster data has a number of pixels. Each pixel stores a color value corresponding to the color of a particular region within the image. The facility then associates one or more single bit per pixel raster planes with the multiple bit per pixel raster data. Each single bit per pixel raster plane corresponds to a color value that appears in the multiple bit per pixel raster data. Each pixel of each single bit per pixel raster plane corresponds to a pixel of the multiple bit per pixel raster data, and indicates whether the corresponding pixel in the multiple bit per pixel raster data contains the color value of the single bit per pixel raster plane. The facility then transmits the associated single bit per pixel raster planes to the display device. Each single bit per pixel raster plane is accompanied by one or more instructions to draw the single bit per pixel raster plane in the corresponding color value.
