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 (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     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
              approximately 8 kilobytes.

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