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.
