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

Save the image as a greyscale image as if it were processed

Specify the compression to use for data written to the
output file: <b>none</b> for no compression, <b>packbits</b>
for PackBits compression, <b>jpeg</b> for baseline JPEG
compression, <b>zip</b> for Deflate compression, and
<b>lzw</b> for Lempel-Ziv &amp; Welch compression
(default).</td></table>

<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
differencing.</td></table>

Specify the planar configuration to use in writing image
data. By default, <i>tiffsv</i> will create a new file with
the data samples packed contiguously. Specifying <b>-p
contig</b> will force data to be written with multi-sample
data packed together, while <b>-p separate</b> will force
samples to be written in separate planes.</td></table>

Specify the number of rows (scanlines) in each strip of data

attempts to set the rows/strip that no more than 8 kilobytes
of data appear in a strip.</td></table>

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

If data are saved compressed and in separate planes, then
the rows in each strip is silently set to one to avoid
