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 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).
