52<p><i>ppm2tiff</i> converts a file in the <small>PPM,
53PGM</small> and <small>PBM</small> image formats to
54<small>TIFF.</small> By default, the <small>TIFF</small>
55image is created with data samples packed
56(<i>PlanarConfiguration</i>=1), compressed with the Packbits
57algorithm (<i>Compression</i>=32773), and with each strip no
58more than 8 kilobytes. These characteristics can be
59overridden, or explicitly specified with the options
