<h2>DESCRIPTION</h2>
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em"><i>tiffgt</i>
|
|
displays one or more images stored using the Tag Image File
|
|
Format, Revision 6.0. Each image is placed in a fixed size
|
|
window that the user must position on the display (unless
|
|
configured otherwise through X defaults). If the display has
|
|
fewer than 24 bitplanes, or if the image does not warrant
|
|
full color, then <small>RGB</small> color values are mapped
|
|
to the closest values that exist in the colormap (this is
|
|
done using the <i>rgbi</i> routine found in the graphics
|
|
utility library <b>−lgutil</b>.)</p>

<p style="margin-left:11%; margin-top: 1em"><i>tiffgt</i>

assumes the colormap has only 8-bit values; otherwise it

assumes 16-bit values. This inspection is done to handle old
