<p><i>tiffcp</i> combines one or more files created

according to the Tag Image File Format, Revision 6.0 into a

single <small>TIFF</small> file. Because the output file may

<p>Group 3 compression can be specified together with
|
|
several T.4-specific options: <b>1d</b> for 1-dimensional
|
|
encoding, <b>2d</b> for 2-dimensional encoding, and
|
|
<b>fill</b> to force each encoded scanline to be zero-filled
|
|
so that the terminating EOL code lies on a byte boundary.
|
|
Group 3-specific options are specified by appending a
|
|
‘‘:’’-separated list to the
|
|
‘‘g3’’ option; e.g. <b>−c
|
|
g3:2d:fill</b> to get 2D-encoded data with byte-aligned EOL

codes.</p>

<!-- INDENTATION -->
|
|
<p><small>LZW</small> compression can be specified together

with a <i>predictor</i> value. A predictor value of 2 causes
|
|
each scanline of the output image to undergo horizontal
|
|
differencing before it is encoded; a value of 1 forces each
|
|
scanline to be encoded without differencing. LZW-specific
|
|
options are specified by appending a
|
|
‘‘:’’-separated list to the
|
|
‘‘lzw’’ option; e.g. <b>−c
|
|
lzw:2</b> for <small>LZW</small> compression with horizontal
