ABSTRACT:
A graphics engine is disclosed which can be used in a colour desktop publishing system. The graphics engine accepts 32-bit RGBM data and performs pixel level calculations under computer control to output processed 32-bit RGBM data. The engine comprises a render processor interface, a run controller including a ramp generator, and a control unit. Interpolators are provided for each colour (RGB) and cascaded with corresponding compositors. A transparency interpolator and matte combiner alter the matte plane of the video image. The engine can output data suitable for rendering by a colour laser printer for a full size A3 page at 400 dots per inch.
