51<p><i>ppm2tiff</i> converts a file in the <small>PPM</small>
52image format to <small>TIFF.</small> By default, the
53<small>TIFF</small> image is created with data samples
54packed (<i>PlanarConfiguration</i>=1), compressed with the
55Lempel-Ziv &amp; Welch algorithm (<i>Compression</i>=5), and
56with each strip no more than 8 kilobytes. These
57characteristics can be overridden, or explicitly specified
58with the options described below</p>
59<!-- INDENTATION -->
60<p>If the <small>PPM</small> file contains greyscale data,
61then the <i>PhotometricInterpretation</i> tag is set to 1
62(min-is-black), otherwise it is set to 2 (RGB).</p>
63<!-- INDENTATION -->
64<p>If no <small>PPM</small> file is specified on the command
65line, <i>ppm2tiff</i> will read from the standard input.</p>
