ppm2tiff converts a file in the <small>PPM,

|
Packit Service |
db44fb |
PGM</small> and <small>PBM</small> image formats to
|
|
Packit Service |
db44fb |
<small>TIFF.</small> By default, the <small>TIFF</small>
|
|
Packit Service |
db44fb |
image is created with data samples packed
|
|
Packit Service |
db44fb |
(PlanarConfiguration=1), compressed with the Packbits
|
|
Packit Service |
db44fb |
algorithm (Compression=32773), and with each strip no
|
|
Packit Service |
db44fb |
more than 8 kilobytes. These characteristics can be
|
|
Packit Service |
db44fb |
overridden, or explicitly specified with the options
|
|
Packit Service |
db44fb |
described below
|
|
Packit Service |
db44fb |
|
|
Packit Service |
db44fb |
If the <small>PPM</small> file contains greyscale data,
|
|
Packit Service |
db44fb |
then the PhotometricInterpretation tag is set to 1
|
|
Packit Service |
db44fb |
(min-is-black), otherwise it is set to 2 (RGB).
|
|
Packit Service |
db44fb |
|
|
Packit Service |
db44fb |
If no <small>PPM</small> file is specified on the command
|
|
Packit Service |
db44fb |
line, ppm2tiff will read from the standard input.
