    NAME
         ppm2tiff - create a TIFF file from a PPM image file
    
    SYNOPSIS
         ppm2tiff [ options ] [ input.ppm ] output.tif
    
    DESCRIPTION
         ppm2tiff converts a file in the PPM image format to TIFF. By
         default,  the TIFF image is created with data samples packed
         (PlanarConfiguration=1), compressed with  the  Lempel-Ziv  &
         Welch algorithm (Compression=5), and with each strip no more
         than 8 kilobytes.  These characteristics can  be  overriden,
         or explicitly specified with the options described below
    
         If the PPM file  contains  greyscale  data,  then  the  Pho-
         tometricInterpretation  tag is set to 1 (min-is-black), oth-
         erwise 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:   -c none for no compression, -c packbits for the
              PackBits compression algorithm, -c jpeg for  the  base-
              line JPEG compression algorithm, -c zip for the Deflate
              compression algorithm, and  -c  lzw  for  Lempel-Ziv  &
              Welch compression (the default).
    
         -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).
