<p><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 & Welch algorithm (<i>Compression</i>=5), and
with each strip no more than 8 kilobytes. These
characteristics can be overridden, or explicitly specified
with the options described below.</p>

<p>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

<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
differencing.</p>

<p>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.</p>

<p>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.</p>
