ppm2tiff(1)				  User Commands 			      ppm2tiff(1)

NAME
       ppm2tiff - create a TIFF file from a PPM image file

SYNOPSIS
       ppm2tiff [options] [input.ppm] output.tif

DESCRIPTION
       ppm2tiff  converts  a  file in the PPM image format to TIFF. By default, the TIFF image is
       created with data samples packed (PlanarConfiguration=1), compressed with  the  Lempel-Ziv
       and  Welch  algorithm (Compression=5), 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 grayscale data, the PhotometricInterpretation tag is set to 1
       (min-is-black). Otherwise, the PhotometricInterpretation tag is set to 2 (RGB).

       If no PPM file is specified on the command line, ppm2tiff reads from the standard input.

OPTIONS
       The following options are supported:

       -c	       Specify a compression scheme to use when writing image data:

		       -c jpeg		       Baseline JPEG compression algorithm.

		       -c lzw		       Lempel-Ziv  and	Welch  algorithm.  This  is   the
					       default algorithm.

		       -c none		       No compression.

		       -c packbits	       PackBits compression algorithm.

		       -c zip		       Deflate compression algorithm.

       -r	       Write data with a specified number of rows per strip. By default, the num-
		       ber of rows per 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
		       per inch.

OPERANDS
       The following operands are supported:

       input.ppm       The name of the input file that contains PPM data.

       output.tif      The name of the output file that contains TIFF data.
