  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
  17 TIFF library.</p>
  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.
  21 <table border cellpadding="3">
  22 <tr>
  23 <td valign="top" width="10%">
  24 <tt>tiffgt&nbsp;&nbsp;&nbsp;&nbsp;</tt></td>
  25 <td>Display the contents of one or more TIFF images using OpenGL.
  26 The software makes extensive use of the <tt>TIFFRGBAImage</tt>
  27 facilities described elsewhere.</td>
  28 </tr>
  29 <tr>
  30 <td valign="top" width="10%"><tt>tiffsv</tt></td>
  31 <td>A program to save all or part of a screen dump on a Silicon
  32 Graphics system. As for <tt>tiffgt</tt> this code, while written to
  33 use the IRIS GL, can be easily tailored to other devices.</td>
  34 </tr>
  35 </table>
  36 <h3>Device-independent Programs</h3>
  37 The remaining programs should be device-independent:
