Alan, If you use the Drools Eclipse plugin, you can easily generate a PNG by using the custom action in the toolbar. There's no simple way using the Drools API, as you basically need Eclipse GEF to generate the graphical representation. It's possible if you add the necessary dependencies though, I suggest you check out the ExportImageAction in the Eclipse plugin.
