Platforms: Polymap Toolkit for Win32s, Win95, WinNT. The Java Polymap
Toolkit runs in Netscape 2.0's and appletviewers for Windows and Unix.

(1) Polymap Toolkit 1.0s (shareware version) defines arbitrary polygon
regions that can be associated with object names in GIF images. 
(2) Java Polymap Applet 1.0 uses the above images to do client-side image
mapping for the WWW with simple tags in the HTML document such as
        <applet code=ImageMap.class width=503 height=453>
        <param name=img value="my_pmap.gif">

Polymap Toolkit allows you to edit Polymap objects in a GIF image.  A
Polymap object consists of one or more polygons and an object name.  A
Polymap GIF file carries one or more Polymap objects in its
application-specific field.  The Polymap information you create is stored
using the application extension of GIF 89a, therefore a Polymap GIF file is
still a valid GIF file that can be read by all GIF readers. Polymap (the
technique) can be used to define polygon regions in the GIF image contained
in the file. By associating the defined regions with descriptive names that
may be interactively displayed, or serve as input to other applications, you
may use Polymap to implement image maps in multimedia applications that
perform certain actions when an object is selected.  The Java Polymap viewer
included in this distribution demonstrates an application of Polymap:
client-side image mapping on the World-Wide Web.  This Java applet provides
the kind of interactivity unavailable in the standard server-side ISMAP.
But unlike other client-side image mapping techniques which keeps messy
region definition information in HTML documents, the Java/Polymap technique
encapsulates compressed Polymap information in the image files, resulting in
a tightly-coupled, and self-contained system that is easy to manage.
Furthermore, through compressing image-mapping information, this mechanism
saves storage space and transmission time.
