<h2>DESCRIPTION</h2>
<p style="margin-left:11%; margin-top: 1em"><i>ppm2tiff</i>
converts a file in the <small>PPM</small> image format to
<small>TIFF.</small> By default, the <small>TIFF</small>
image is created with data samples packed
(<i>PlanarConfiguration</i>=1), compressed with the
2002-10-07 09:47:36 -04:00
Lempel-Ziv &amp; Welch algorithm (<i>Compression</i>=5), and
with each strip no more than 8 kilobytes. These
2005-12-29 17:01:44 -05:00
characteristics can be overridden, or explicitly specified
2005-03-06 06:11:43 -05:00
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
2005-03-06 06:11:43 -05:00
(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>
