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.
