Several 15of these tools are useful in their own right. Many of them however 16are more intended to serve as programming examples for using the 17TIFF library.</p> 18<h3>Device-dependent Programs</h3> 19There are two device-dependent programs that serve as simple 20examples for writing programs to display and save TIFF images. 21<table border cellpadding="3"> 22<tr> 23<td valign="top" width="10%"> 24<tt><a href="man/tiffgt.1.html">tiffgt</a> </tt></td> 25<td>Display the contents of one or more TIFF images using OpenGL. 26The software makes extensive use of the <tt>TIFFRGBAImage</tt> 27facilities described elsewhere.</td> 28</tr> 29<tr> 30<td valign="top" width="10%"><tt><a href="man/tiffsv.1.html">tiffsv</a></tt></td> 31<td>A program to save all or part of a screen dump on a Silicon 32Graphics system.
