RAS2TIFF(1)RAS2TIFF(1)NAMEras2tiff - create a TIFF file from a Sun rasterfile
SYNOPSISras2tiff [ options ] input.ras output.tif
DESCRIPTIONras2tiff converts a file in the Sun rasterfile 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 characteris
tics can overriden, or explicitly specified with the
options described below.
Any colormap information in the rasterfile is carried over
to the TIFF file by including a Colormap tag in the output
file. If the rasterfile has a colormap, the Photo_
metricInterpretation 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.
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).
-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 handle all possible rasterfiles. In particular,
ras2tiff does not handle run-length encoded images.
