TIFF Group
3 is the universal protocol for sending fax documents through
a phone line. In this group each scan line is encoded
independently.
TIFF Group 3 1D - a scan line is encoded as a set of runs, each representing
a number of white or black pixels, with white and black runs alrenating.
Every run is encoded using a different number of bits, which can be uniquely
identified when decoded. Reoccurring lengths of runs will be encoded efficiently,
while infrequent runs cause the size to grow.
TIFF Group 3 2D - G3 2-D is a combination of G3 1-D and G4 compression
schemes.
TIFF Group 3 (G3) support
is included in the following Black Ice printer drivers:
