User:Jiangxin/Improved Freemind Extension
This improved freemind extension is based on AlexLane's. Orignal extension page is here.
Usage
editYou can use any internal/external link wiki support as mindmap extension parameter. Example:
- <mindmap width="100%" height="500px">[http://www.worldhello.net/doc/wiki.mm Johnson's Wiki tutorial]</mindmap>
- <mindmap>New upload mm file: [[Media:Wiki.mm]]</mindmap>
Improvement of this extension
editI like this idea embedding mindmap into wiki's page. This extension works but needs some enhancement.
- Various of links no matter internal or external free link can be used;
- Add parameters, width, height, bgcolor, to custom display;
- Default using flash (visorFreemind.swf) as web interface; --Jiangxin 21:36, 16 April 2006 (UTC)
