  • Patent number: 6344901
    Abstract: A method and apparatus to integrate a uniform bit-depth rasterizer and a non-uniform bit-depth print engine is disclosed. When using the non-uniform bit-depth print engine to print uniform bit-depth pixel data, undesirable printout due to incompatibility of the different bit-depths will result. Prior to forwarding of pixel data to the print engine, pixel data is linearized and halftoned. According to the preferred embodiment, to accomplish integration of the uniform bit-depth rasterizer and the non-uniform bit-depth print engine, some linearized components are scaled prior to halftoning. After halftoning, an appropriate number of most significant bits are discarded from the components which are scaled earlier to obtain effectively a non-uniform bit-depth pixel data.
