ras2tiff, sgi2tiff, sgisv, and ycbcr are completely removed from the distribution. The libtiff tools rgb2ycbcr and thumbnail are only built in the build tree for testing. Old files are put in new 'archive' subdirectory of the source repository, but not in distribution archives. These changes are made in order to lessen the maintenance burden.

<p><i>ras2tiff</i> converts a file in the Sun rasterfile
|
|
format to <small>TIFF.</small> By default, the
|
|
<small>TIFF</small> image is created with data samples
|
|
packed (<i>PlanarConfiguration</i>=1), compressed with the
|
|
Lempel-Ziv & Welch algorithm (<i>Compression</i>=5), and
|
|
with each strip no more than 8 kilobytes. These
|
|
characteristics can overridden, or explicitly specified with
|
|
the options described below.</p>
|
|
<!-- INDENTATION -->
|
|
<p>Any colormap information in the rasterfile is carried
|
|
over to the <small>TIFF</small> file by including a
|
|
<i>Colormap</i> tag in the output file. If the rasterfile
|
|
has a colormap, the <i>PhotometricInterpretation</i> 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.</p>
