DESCRIPTION
Sgi2tiff
converts a file in the
SGI
image format to
TIFF.
By default, the
TIFF
image is created with data samples packed (PlanarConfiguration=1),
compressed with the Lempel-Ziv & Welch algorithm (Compression=5),
and with each strip no more than 8 kilobytes.
These characteristics can overriden, or explicitly specified
with the following options:
-none
(use no compression),
-packbits
(use the PackBits compression algorithm),
-lzw
(use Lempel-Ziv & Welch - default),
-rowsperstrip
n
(pack
n
rows in each strip).
Any colormap information in the rasterfile is carried over to the
TIFF
file by including a
Colormap
tag in the output file.
If the rasterfile has a colormap, the
PhotometricInterpretation
tag is set to 3 (palette);
otherwise it is set to 2 (RGB) if the depth
is 24 or 1 (min-is-black) if the depth is not 24.
BUGS
Does not record colormap information.
