    CCITT Group 3 is officially know as the CCITT T.4 Standard.

    This is a 1-D version of the CCITT Group 3 compression scheme. It uses a static table of values to assign codes to run lengths. Frequently occurring run lengths are given smaller codes. (The most frequent are usually black runs of 2 or 4 pixels).
