[mapserver-users] Creating legend

[Steve Lime]

Visit:

  http://www.openlayers.org/dev/examples/example-list.html

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 
usually set in OL.
Thanks for your help.
