Tools Overview</font>
|
|
Packit |
994f1a |
This software distribution comes with a small collection of
|
|
Packit |
994f1a |
programs for converting non-TIFF format images to TIFF and for
|
|
Packit |
994f1a |
manipulating and interrogating the contents of TIFF images. Several
|
|
Packit |
994f1a |
of these tools are useful in their own right. Many of them however
|
|
Packit |
994f1a |
are more intended to serve as programming examples for using the
|
|
Packit |
994f1a |
TIFF library.
|
|
Packit |
994f1a |
Device-dependent Programs
|
|
Packit |
994f1a |
There are two device-dependent programs that serve as simple
|
|
Packit |
994f1a |
examples for writing programs to display and save TIFF images.
