PPM2TIFF(1)                                           PPM2TIFF(1)

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 Lem-
       pel-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 Photo-
       metricInterpretation 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 baseline 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).
