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