ppm2tiff − create a <small>TIFF</small> file from

<small>PPM, PGM</small> and <small>PBM</small> image

files

SYNOPSIS

       cols="2" cellspacing="0" cellpadding="0">

ppm2tiff [ options ] [ input.ppm ]

output.tif

DESCRIPTION

       cols="2" cellspacing="0" cellpadding="0">

ppm2tiff converts a file in the <small>PPM,</small>

PGM and <small>PBM</small> image formats to

<small>TIFF.</small> By default, the <small>TIFF</small>

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 <small>PPM</small> file contains greyscale data,

then the PhotometricInterpretation tag is set to 1

(min-is-black), otherwise it is set to 2 (RGB).

If no <small>PPM</small> file is specified on the command

line, ppm2tiff will read from the standard input.

OPTIONS

       cols="5" cellspacing="0" cellpadding="0">

−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).
