[OpenLayers-Users] opacity and wms.notile layer...

[John Cole]

Chris,
  I've changed my layer def as follows:

			var aca_revite_wms = new
OpenLayers.Layer.WMS.Untiled( "PostGIS GDT ACA/Revite Overlay", 
 
"http://kong.uai.int/cgi-bin/mapserv.exe?map=/mapserver/gdt/props.map&", 
				{layers: 'revite,aca', 'ratio':ratio,
transparent:true, 
                format:'image/png', visiblity:false, opacity: 0.5});

and it still appears as an opaque layer.  Should I have anything special in
my mapfile to make the polygons a transparent layer?  

I believe I got the visible:false from one of the example pages, I'll try
and see if that was indeed the case and note it for you.

Thanks,

John

You want to pass all of your options in a single object.
 { 'ratio': ratio, 'opacity': 0.5, 'visibility': false }

(Note 'visibility', not 'visible'.)

Can you point to the example that lead you to believe you needed to do
something different?
