<p><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>
<!-- INDENTATION -->
<p>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>
<!-- INDENTATION -->
<p>If no <small>PPM</small> file is specified on the command
line, <i>ppm2tiff</i> will read from the standard input.</p>
