ppm2tiff - create a TIFF file from PPM, PGM and PBM image files
Synopsis
ppm2tiff [ options ] [ input.ppm ] output.tif
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.
-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).
