.TH SGI2TIFF 1 "November 2, 2005" "libtiff"
.SH NAME
sgi2tiff \- create a
.SM TIFF
file from an
.SM SGI
image file
.SH SYNOPSIS
.B sgi2tiff
[
.I options
]
.I input.rgb
.I output.tif
.SH DESCRIPTION
.I sgi2tiff
converts a file in the 
.SM SGI
image format to
.SM TIFF.
By default, the
.SM TIFF
image is created with data samples packed (\c
.IR PlanarConfiguration =1),
compressed with the Lempel-Ziv & Welch algorithm (\c
.IR Compression =5),
and with each strip no more than 8 kilobytes.
These characteristics can overridden, or explicitly specified
with the options described below.
.SH OPTIONS
.TP
.B \-c
Specify a compression scheme to use when writing image data:
.B "\-c none"
for no compression,
.B "\-c packbits"
for the PackBits compression algorithm),
.B "\-c jpeg"
for the baseline JPEG compression algorithm,
.B "\-c zip
for the Deflate compression algorithm,
and
.B "\-c lzw"
for Lempel-Ziv & Welch (the default).
.TP
.B \-p
Explicitly select the planar configuration used in organizing
data samples in the output image:
.B "\-p contig"
for samples packed contiguously, and
.B "\-p separate"
for samples stored separately.
By default samples are packed.
.TP
.B \-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.
.SH BUGS
Does not record colormap information.
