<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><i>ppm2tiff</i>
converts a file in the <small>PPM, PGM</small> and
<small>PBM</small> image formats to <small>TIFF.</small> By
default, the <small>TIFF</small> image is created with data
samples packed (<i>PlanarConfiguration</i>=1), compressed
with the Packbits algorithm (<i>Compression</i>=32773), and
with each strip no more than 8 kilobytes. These
characteristics can be overridden, or explicitly specified
with the options described below</p>
<p style="margin-left:11%; margin-top: 1em">If the
<small>PPM</small> file contains greyscale data, then the
<i>PhotometricInterpretation</i> tag is set to 1
(min-is-black), otherwise it is set to 2 (RGB).</p>
<p style="margin-left:11%; margin-top: 1em">If no
<small>PPM</small> file is specified on the command line,
<i>ppm2tiff</i> will read from the standard input.</p>
