PPM2TIFF(1)			     General Commands Manual			      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 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 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: -c none  for  no  com-
	      pression, -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).
