NAME¶
sgi2tiff - create a
TIFF file from an
SGI image
file
SYNOPSIS¶
sgi2tiff [
options ]
input.rgb output.tif
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 overridden, or explicitly
specified with the options described below.
OPTIONS¶
- -c
- Specify a compression scheme to use when writing image data: -c
none for no compression, -c packbits for the PackBits
compression algorithm), -c jpeg for the baseline JPEG compression
algorithm, -c zip for the Deflate compression algorithm, and -c
lzw for Lempel-Ziv & Welch (the default).
- -p
- Explicitly select the planar configuration used in organizing data samples
in the output image: -p contig for samples packed contiguously, and
-p separate for samples stored separately. By default samples are
packed.
- -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.
BUGS¶
Does not record colormap information.
