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 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 com-
pression, -c jpeg for baseline JPEG compression, -c zip for De-
flate 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 ap-
proximately 8 kilobytes.
-R resolution
Mark the resultant image to have the specified X and Y resolu-
tion (in dots/inch).
