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 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 approxi-
	      mately 8 kilobytes.

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