NAME

       ppm2tiff - create a TIFF file from PPM, PGM and PBM image files

SYNOPSIS

       ppm2tiff [ options ] [ input.ppm ] output.tif

DESCRIPTION

       ppm2tiff  converts  a  file in the PPM, PGM and PBM image formats to TIFF.  By default, the TIFF image is
       created with  data  samples  packed  (PlanarConfiguration=1),  compressed  with  the  Packbits  algorithm
       (Compression=32773),  and  with  each  strip  no  more  than  8  kilobytes.  These characteristics can be
       overridden, or explicitly specified with the options described below

       If the PPM file contains greyscale data, then the PhotometricInterpretation tag  is  set  to  1  (min-is-
       black), otherwise it is set to 2 (RGB).

       If no PPM file is specified on the command line, ppm2tiff will read from the standard input.

OPTIONS

       -c     Specify a compression scheme to use when writing image data: none for no compression, packbits for
              PackBits  compression  (will be used by default), lzw for Lempel-Ziv & Welch compression, jpeg for
              baseline JPEG compression, zip for Deflate compression, g3 for CCITT Group  3  (T.4)  compression,
              and g4 for CCITT Group 4 (T.6) compression.

       -r     Write  data  with  a  specified  number  of rows per strip; by default the number of rows/strip is
              selected so that each strip is approximately 8 kilobytes.

       -R     Mark the resultant image to have the specified X and Y resolution (in dots/inch).
