.SH DESCRIPTION
|

|
|
|
.I ppm2tiff
|
|
|
|
|
converts a file in the
|
2006-03-01 06:20:33 -05:00
|

|
.SM PPM, PGM
|
|
|

.SM TIFF.
|
|
|
|
|
By default, the
|
|
|
|
|
.SM TIFF
|
|
|
|
|
image is created with data samples packed (\c
|
|
|
|
|
.IR PlanarConfiguration =1),
|
2006-03-01 06:20:33 -05:00
|
|
|
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

If the
|
|
|
|
|
.SM PPM
|

|
.I PhotometricInterpretation
|
2006-03-01 06:20:33 -05:00
|
|
|
tag is set to 1 (min-is-black), otherwise it is set to 2 (RGB).
