PPM2TIFF(1)									      PPM2TIFF(1)

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 compres-
	      sion, packbits for PackBits compression (will be used by default), lzw for  Lempel-
	      Ziv  &  Welch compression, jpeg for baseline JPEG compression, zip for Deflate com-
	      pression, 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).
