ras2tiff(1) User Commands 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 (PlanarCon‐
figuration=1), compressed with the Lempel-Ziv and Welch algorithm (Com‐
pression=5), and with each strip no more than 8 kilobytes. These char‐
acteristics can be overridden 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 PhotometricInterpretation tag is set to 3 (pal‐
ette). Otherwise, the PhotometricInterpretation tag is set to 2 (RGB)
if the depth is 24, or to 1 (min-is-black) if the depth is not 24.
OPTIONS
The following options are supported:
-c Specify a compression scheme to use when writing image
data:
-c jpeg Baseline JPEG compression algo‐
rithm.
-c lzw Lempel-Ziv and Welch algorithm.
This is the default algorithm.
-c none No compression.
-c packbits PackBits compression algorithm.
-c zip Deflate compression algorithm.
-r Write data with a specified number of rows per strip.
By default, the number of rows per strip is selected so
that each strip is approximately 8 kilobytes.
OPERANDS
The following operands are supported:
input.ras The name of the input file that contains Sun rasterfile
data.
output.tif The name of the output file that contains TIFF data.

not support run-length encoded images.
