<i>tiffsv</i> saves all or part of the framebuffer in a file
45
using the Tag Image File Format, Revision 6.0. By default,
46
the image is saved with data samples packed
47
(<i>PlanarConfiguration</i>=1), compressed with the
48
Lempel-Ziv & Welch algorithm (<i>Compression</i>=5), and
49
with each strip no more than 8 kilobytes. These
50
characteristics can be overriden, or explicitly specified
51
with the options described below.</td></table>

<small>LZW</small> compression can be specified together
92
with a <i>predictor</i> value. A predictor value of 2 causes
93
each scanline of the output image to undergo horizontal
94
differencing before it is encoded; a value of 1 forces each
95
scanline to be encoded without differencing. LZW-specific
96
options are specified by appending a ``:''-separated list to
97
the ``lzw'' option; e.g. <b>-c lzw:2</b> for
98
<small>LZW</small> compression with horizontal
99
differencing.</td></table>

Except for the use of <small>TIFF,</small> this program is
140
equivalent to the standard <i>scrsave</i> program. This
141
means, for example, that you can use it in conjunction with
142
the standard <i>icut</i> program simply by creating a link
143
called <i>scrsave</i>, or by creating a shell script called
144
<i>scrsave</i> that invokes <i>tiffgt</i> with the

appropriate options.</td></table>
