CCITT Group 3 and 4 formats are often referred to as “fax
compression” methods. They were designed to be used by fax
machines for electronic data transmission. However, they are also
popular methods for storing documents electronically, particularly
Group 4. TIFF Type 2 is also called “Modified Huffman run-length
encoding,” and is a variant of CCITT Group 3. TIFF PackBits is a
simple form of run-length encoding, which stores data as sequences
of uncompressed bytes or as repeat-counts.
