TIFF Group 4 is a protocol used for sending
fax documents through an ISDN line. In this group scan lines
are encoded with reference to the previous one, creating better
compression ratios.
TIFF Group 4 2D - encoding is more than Group 3 encoding.
Each scan line is compared to the scan line before it. High levels of
compression
can be used based on vertical attributes of the image.
TIFF Group 4 support is
included in the following Black Ice printer drivers:
