Introduction

This extension includes well known HTML Image-Maps to MediaWiki. Please note that i am a php beginner. Bugs might appear. I tested it with my Wiki, it works fine. But that doesn't mean it does for yours. Please report any bugs below. It should work with Version 1.4 and higher. Thanks.

Syntax

<htmlmap>[source|mapname|width|height]{shape|coords|url|alt}</htmlmap>
<htmlmap>[source|mapname|width|height]{shape|coords|url|alt}{shape|coords|url|alt}</htmlmap>
<htmlmap>[source|mapname|width|height]{shape|coords|url|alt}{shape|coords|url|alt}{shape|coords|url|alt}{shape|coords|url|alt}...</htmlmap>

• [] - concerning the visible image, once

* source - where the image is located
* mapname - random name
* width - width of image
* height - of image

• {}- concerning clickable points in image, unlimited (as much clickable points you want)

* shape - can be "rect", "circle" or "polygon"
* coords - "x,x,x,x" for rect; "x,x,x" for circle; "x,x,x,..." for polygon
* url - url where to link
* alt - alternative text

Maybe very confusing at the first time of use. Just look at any HTML Guide to ImageMaps for more Information. This extension just kind of translates the code, so u can use it in MediaWiki Software.

Example

<htmlmap>[http://petition.panzertierzone.de/images/petition.png|Petition|468|60]{rect|10,10,50,50|http://petition.panzertierzone.de|Petition}</htmlmap>
