.TH PPM2TIFF 1 "March 1, 2006" "libtiff"
.SH NAME
ppm2tiff \- create a
.SM TIFF
file from
.SM PPM, PGM
and
.SM PBM
image files
.SH SYNOPSIS
.B ppm2tiff
[
.I options
] [
.I input.ppm
]
.I output.tif
.SH DESCRIPTION
.I ppm2tiff
converts a file in the
.SM PPM, PGM
and
.SM PBM
image formats to
.SM TIFF.
By default, the
.SM TIFF
image is created with data samples packed (\c
.IR PlanarConfiguration =1),
compressed with the Packbits algorithm (\c
.IR Compression =32773),
and with each strip no more than 8 kilobytes. These characteristics can be
overridden, or explicitly specified with the options described below
.PP
If the
.SM PPM
file contains greyscale data, then the
.I PhotometricInterpretation
tag is set to 1 (min-is-black), otherwise it is set to 2 (RGB).
.PP
If no
.SM PPM
file is specified on the command line,
.I ppm2tiff
will read from the standard input.
.SH OPTIONS
.TP
.B \-c
Specify a compression scheme to use when writing image data:
.B none
for no compression,
.B packbits
for PackBits compression (will be used by default),
.B lzw
for Lempel-Ziv & Welch compression,
.B jpeg
for baseline JPEG compression,
.B zip
for Deflate compression,
.B g3
for CCITT Group 3 (T.4) compression,
and
.B g4
for CCITT Group 4 (T.6) compression.
.TP
.B \-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.
.TP
.B \-R
Mark the resultant image to have the specified X and Y resolution (in
dots/inch).
