PPM2TIFF(1)                                                        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 (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 Pack-
              Bits 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 approximately 8 kilobytes.

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