PPM2TIFF(1)		    General Commands Manual		   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 (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  ap-
	      proximately 8 kilobytes.

       -R     Mark  the	 resultant image to have the specified X and Y resolu-
	      tion (in dots/inch).
