.TH RAS2TIFF 1 "May 2, 1989"
.SH NAME
ras2tiff \- create a
.SM TIFF
file from a Sun rasterfile
.SH SYNOPSIS
.B ras2tiff
[
.B \-none
] [
.B \-packbits
] [
.B \-lzw
] [
.B \-rowsperstrip
.I n
]
.I "rasterfile tiff-file"
.SH DESCRIPTION
.I Ras2tiff
converts a file in the Sun rasterfile 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 overriden, or explicitly specified
with the following options:
.B \-none
(use no compression),
.B \-packbits
(use the PackBits compression algorithm),
.B \-lzw
(use Lempel-Ziv & Welch \- default),
.B \-rowsperstrip
.I n
(pack
.I n
rows in each strip).
Any colormap information in the rasterfile is carried over to the
.SM TIFF
file by including a
.I Colormap
tag in the output file.
If the rasterfile has a colormap, the
.I 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.
.SH BUGS
Does not handle all possible rasterfiles.
In particular, 
.I ras2tiff
does not handle run-length encoded images.
