ras2tiff - create a TIFF
file from a Sun
rasterfile
ras2tiff [ options ] input.ras output.tif
ras2tiff 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 characteristics 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
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.
- -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.
Does not handle all possible rasterfiles. In particular,
ras2tiff does not handle run-length encoded images.
