ras2tiff - Unix, Linux Command
ras2tiff - create a
TIFF file from a Sun rasterfile
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 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 (palette);
otherwise it is set to 2 (RGB) if the depth
is 24 or 1 (min-is-black) if the depth is not 24.
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,
-c lzw for Lempel-Ziv & Welch (the default).
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.
ras2tiff does not handle run-length encoded images.
