ABSTRACT:
An image to be generated is analyzed to determine whether it is comprised solely of bi-level color data. If so, an indication is provided to a rendering device that a simpler rendering procedure, suitable for bi-level data, can be employed. However, full color information pertaining to the image is retained. If the rendering device is able to process the image data in a bi-level format, it does so, to thereby improve performance and reduce the amount of memory capacity that is required. If multi-level data is detected, the bi-level data is expanded and full color rendering is carried out in a conventional fashion.
