[mapserver-users] Creating legend

[Fawcett, David]

Or, just a straight mode=legend request to the CGI if you are using MapServer.  You can pass in your extent, that will manage the scale-dependent layers.

	Also, you might want to consider making a separate GetLegendGraphic WMS request and putting the legend in a separate DIV element in your web page.  
	
	Just an idea.

		and search for untiled. There's a "WMS Untiled" example you can view the source of. The singleTile option goes in the "options" object as opposed the "params" object. Params get passed to the WMS service, options are handled by OL.

		Hi Steve,
		It would be great if you can give me an example or tell me where it is
