PPM2TIFF(1) User Commands PPM2TIFF(1)
NAME
ppm2tiff - create a TIFF file from PPM, PGM and PBM image files
SYNOPSIS
ppm2tiff [
options ] [
input.ppm ]
output.tifDESCRIPTION
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 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
resolution (in dots/inch).
