11 Tools Overview
</font></h1>
12 <p>This software distribution comes with a small collection of
13 programs for converting non-TIFF format images to TIFF and for
14 manipulating and interogating the contents of TIFF images. Several
15 of these tools are useful in their own right. Many of them however
16 are more intended to serve as programming examples for using the
18 <h3>Device-dependent Programs
</h3>
19 There are two device-dependent programs that serve as simple
20 examples for writing programs to display and save TIFF images.
