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 (Planar-
       Configuration=1),  compressed  with  the  Packbits  algorithm (Compres-
       sion=32773), and with each strip no more than 8 kilobytes. These  char-
       acteristics can be overridden, or explicitly specified with the options
       described below

       If the PPM file contains greyscale data, then the  PhotometricInterpre-
       tation 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 resolu-
              tion (in dots/inch).
