Abstract
A processing system for controlling a computer graphics display stores and processes bit-mapped digital pixel values to generate color display signals. The system incorporates memory elements for storing control values for each pixel, in association with color values for each pixel. Processing modules responsive to the per-pixel control and color values generate color display signals. Embedding per-pixel control information in the bitmap in association with per-pixel color information enables each pixel to independently control the operation of the processing modules on that pixel.
