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 compress
	      Specify a	compression scheme to use when writing image data:  -c
	      none  for	 no  compression, -c packbits for PackBits compression
	      (will be used by default), -c lzw	for Lempel-Ziv	&  Welch  com-
	      pression,	 -c jpeg for baseline JPEG compression,	-c zip for De-
	      flate compression, -c g3 for CCITT Group	3  (T.4)  compression,
	      and -c g4	for CCITT Group	4 (T.6)	compression.

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