| 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 interrogating 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.
