.SH NAME
|
|
ppm2tiff \- create a
|
|
.SM TIFF

|
|
.B ppm2tiff
|
|

.I options
|

.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).
