PPM2TIFF(1)			     LibTIFF			     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 (PlanarConfigu-
     ration=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 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 compression, -c jpeg
	    for baseline JPEG compression, -c zip for Deflate 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 approximately
	    8 kilobytes.

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