.SH NAME

ras2tiff \- create a

.SM TIFF

file from a Sun rasterfile

.SH SYNOPSIS

.B ras2tiff

[

.I options

]

.I input.ras

.I output.tif

.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 overridden, or explicitly specified

with the options described below.

.PP

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 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 \-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 handle all possible rasterfiles.

In particular, 

.I ras2tiff

does not handle run-length encoded images.
