With this Plugin for [JSPWiki|http://www.jspwiki.org] you can use [Image Maps|Google:Image Map Tutorial] on your pages in a very easy way. The plugin can be used the same way like the normal [ImagePlugin|JSPWiki:Image]. The map points and links can be edited by a simple web based wizard, or you can type the map points in the plugin text.

If you click on the edit-link at the right bottom corner of the picture, you will jump to the image map wizard, just try it.

!Example

[{ImageMap image='deutschland.png'

NordrheinWestfalen;50;170;20
http://www.berlin.de;217;115;20
http://www.bayern.de;165;273;20
http://www.hessen.de;91;204;20

Oslo;83;294;20
}]

is created by the following plugin definition:

{{{
[{ImageMap image='deutschland.gif'

NordrheinWestfalen;50;170;20
http://www.berlin.de;217;115;20
http://www.bayern.de;165;273;20
http://www.hessen.de;91;204;20
}]
}}}

!ImageMap-Plugin-Parameters
|| Name || Description || Necessity
| image | URL or attachment name of the image | required
| align | center, left, right | optional (none)
| width | size of the image | optional
| height |size of the image | optional

It is important that the plugin text has a body part, that is the text after the blank line under the {{ImageMap}} definition. Here the wizard stores the link and point parameters in the form {{link;x;y;r}}. So an empty ImageMap must have a blank line before the closing brakets.

By default a circle with radius r is used. Link can be any wiki link. You can specify other shapes like {{link;polygon;x1;y1;x2;y2;...;xn;yn;}} or {{link;rect;x1;y1;x2;y2;}} but at the moment the wizard just creates circle shapes with radius 20. Other shapes are working but must be edited by hand in the page text for the time beeing.
