SYNOPSIS
ppm2tiff
[
options
] [
input.ppm
]
output.tif
DESCRIPTION
ppm2tiff
converts a file in the
PPM
image format to
TIFF.
By default, the
TIFF
image is created with data samples packed (PlanarConfiguration=1),
compressed with the Lempel-Ziv & Welch algorithm (Compression=5),
and with each strip no more than 8 kilobytes.
These characteristics can be overriden, 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:
-c none
for no compression,
-c packbits
for the PackBits compression algorithm,
-c jpeg
for the baseline JPEG compression algorithm,
-c zip
for the Deflate compression algorithm,
and
-c lzw
for Lempel-Ziv & Welch compression (the default).
- -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).
