| 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 </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> | |

| 36 | <h3>Device-independent Programs</h3> | |
| 37 | The remaining programs should be device-independent: | |
