TIFF Tools Overview</h1>

2006-01-02 21:16:07 -05:00
|
|
|
<p>This software distribution comes with a small collection of
|
|
|
|
|
programs for converting non-TIFF format images to TIFF and for
|
2006-04-20 07:48:42 -04:00
|
|
|
manipulating and interrogating the contents of TIFF images. Several
|
2006-01-02 21:16:07 -05:00
|
|
|
of these tools are useful in their own right. Many of them however
|
|
|
|
|
are more intended to serve as programming examples for using the
|
|
|
|
|
TIFF library.</p>
|
|
|
|
|
<h3>Device-dependent Programs</h3>
|
|
|
|
|
There are two device-dependent programs that serve as simple
|
|
|
|
|
examples for writing programs to display and save TIFF images.
