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 and Welch algorithm (Compression=5), and with each strip no more than 8 kilobytes. These characteristics 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 (palette). 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.
The following options are supported:
-c Specify a compression scheme to use when writing image data:
-c jpeg Baseline JPEG compression algorithm.
-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.
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.

Does not support all possible rasterfiles. In particular, ras2tiff does not support run-length encoded images.
