34<I>ppm2tiff</I>
35
36converts a file in the
37<FONT SIZE="-1">PPM</FONT>
38image format to
39<FONT SIZE="-1">TIFF.</FONT>
40By default, the
41<FONT SIZE="-1">TIFF</FONT>
42image is created with data samples packed (<I>PlanarConfiguration</I>=1),
43
44compressed with the Lempel-Ziv &amp; Welch algorithm (<I>Compression</I>=5),
45
46and with each strip no more than 8 kilobytes.
47These characteristics can be overriden, or explicitly specified
48with the options described below
49<P>
50
51If the
52<FONT SIZE="-1">PPM</FONT>
53file contains greyscale data, then the
54<I>PhotometricInterpretation</I>
55
56tag is set to 1 (min-is-black),
57otherwise it is set to 2 (RGB).
58<P>

60If no
61<FONT SIZE="-1">PPM</FONT>
62file is specified on the command line,
63<I>ppm2tiff</I>
64
