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 (PlanarCon- figuration=1), compressed with the Lempel-Ziv & Welch algorithm (Compression=5), and with each strip no more than 8 kilobytes. These char- acteristics 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 raster- file 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 approxi- mately 8 kilobytes.
Does not handle all possible rasterfiles. In particular, ras2tiff does not handle run-length encoded images.
