12 ras2tiff converts a file in the Sun rasterfile format to TIFF. By
13 default, the TIFF image is created with data samples packed (PlanarCon‐
14 figuration=1), compressed with the Lempel-Ziv & Welch algorithm (Com‐
15 pression=5), and with each strip no more than 8 kilobytes. These char‐
16 acteristics can overridden, or explicitly specified with the options
17 described below.
18
19 Any colormap information in the rasterfile is carried over to the TIFF
20 file by including a Colormap tag in the output file. If the rasterfile
21 has a colormap, the PhotometricInterpretation tag is set to 3 (pal‐
22 ette); otherwise it is set to 2 (RGB) if the depth is 24 or 1 (min-is-
23 black) if the depth is not 24.
24
26 -c Specify a compression scheme to use when writing image data: -c
27 none for no compression, -c packbits for the PackBits compres‐
28 sion algorithm, -c jpeg for the baseline JPEG compression algo‐
29 rithm, -c zip for the Deflate compression algorithm, and -c lzw
30 for Lempel-Ziv & Welch (the default).
31
32 -r Write data with a specified number of rows per strip; by default
33 the number of rows/strip is selected so that each strip is
34 approximately 8 kilobytes.
35
37 Does not handle all possible rasterfiles. In particular, ras2tiff does
38 not handle run-length encoded images.
