RAS2TIFF(1) RAS2TIFF(1) NAME ras2tiff - create a TIFF file from a Sun rasterfile SYNOPSIS ras2tiff [ options ] input.ras output.tif DESCRIPTION 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 (Com- pression=5), and with each strip no more than 8 kilobytes. These char- acteristics 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. OPTIONS -c Specify a compression scheme to use when writing image data: -c none for no compression, -c packbits for the PackBits compres- sion algorithm, -c jpeg for the baseline JPEG compression algo- rithm, -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. BUGS Does not handle all possible rasterfiles. In particular, ras2tiff does not handle run-length encoded images.
