MH (Modified Huffman)
method
This compression method is
the same as the one-dimen-
sional coding method of the
CCITT Group 3 Fax.
This compression method is
used for two color mono-
chrome images only.
The value of the Compression
(259) must be set to 3 and the
T4Options (292) tag must be
set to 1. Also, the value of the
StripByteCounts (279) tag
must be set to the size (in
bytes) of the compressed data.
MMR (Modified Modified
Read) method
This compression method is
the same as the CCITT Group
4 Fax coding method.
This compression is used for
two color monochrome imag-
es only.
The value of the Compression
(259) tag must be set to 4 and
the T4Options (292) tag can-
not be included. Also, the val-
ue of the StripByteCounts
(279) tag must be set to the
size (in bytes) of the com-
pressed data.
LZW (Lempel, Ziv, Welch)
method
The value of the Compression
(259) tag must be set to 5. Also,
the value of the StripByte-
Counts (279) tag must be set to
the size (in bytes) of the com-
pressed data.
This method uses the data
compression algorithm origi-
nally devised by Terry Welch
of Sperry (currently Unisys),
and later used as a dictionary
“LZ77” algorithm by Abra-
ham Lempel and Jacob Ziv.
