Tools Overview</font></h1>
<p>This software distribution comes with a small collection of
programs for converting non-TIFF format images to TIFF and for
manipulating and interrogating the contents of TIFF images. Several
of these tools are useful in their own right. Many of them however
are more intended to serve as programming examples for using the
TIFF library.</p>
<h3>Device-dependent Programs</h3>
There are two device-dependent programs that serve as simple
examples for writing programs to display and save TIFF images.
<table border cellpadding="3">
<tr>
<td valign="top" width="10%">
<tt><a href="man/tiffgt.1.html">tiffgt</a>&nbsp;&nbsp;&nbsp;&nbsp;</tt></td>
<td>Display the contents of one or more TIFF images using OpenGL.
The software makes extensive use of the <tt>TIFFRGBAImage</tt>
facilities described elsewhere.</td>
</tr>
<tr>
<td valign="top" width="10%"><tt><a href="man/tiffsv.1.html">tiffsv</a></tt></td>
<td>A program to save all or part of a screen dump on a Silicon
Graphics system. As for <tt>tiffgt</tt> this code, while written to
use the IRIS GL, can be easily tailored to other devices.</td>
</tr>
</table>
<h3>Device-independent Programs</h3>
The remaining programs should be device-independent:
<table border cellpadding="3">
