52 <p><i>ras2tiff</i> converts a file in the Sun rasterfile |
|
53 format to <small>TIFF.</small> By default, the |
|
54 <small>TIFF</small> image is created with data samples |
|
55 packed (<i>PlanarConfiguration</i>=1), compressed with the |
|
56 Lempel-Ziv & Welch algorithm (<i>Compression</i>=5), and |
|
57 with each strip no more than 8 kilobytes. These |

58 characteristics can overridden, or explicitly specified with |

59 the options described below.</p> |

|
61 <p>Any colormap information in the rasterfile is carried |
|
62 over to the <small>TIFF</small> file by including a |
|
63 <i>Colormap</i> tag in the output file. If the rasterfile |
|
64 has a colormap, the <i>PhotometricInterpretation</i> tag is |
|
65 set to 3 (palette); otherwise it is set to 2 (RGB) if the |
|
66 depth is 24 or 1 (min-is-black) if the depth is not 24.</p> |
