|
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. |
|

37 The remaining programs should be device-independent: |
