Pete,
I managed to do this in 2 different ways :
1. Use the alpha hack on .png
var boundaries = new OpenLayers.Layer.WMS("Layer1",
"http://your-url";,
{ layers: "0,1,2"
,transparent: "true"
,srs: "EPSG:3035"
},
{'buffer':0, 'format':"image/png", 'isBaseLayer':false,
'transparent':true},
{'alpha':true}
);
2. Specify "image/gif" as the format ( but I think you specify your
format in the wrong place !! )
var boundaries = new OpenLayers.Layer.WMS("Layer1",
"http://your-url";,
{ layers: "0,1,2"
,transparent: "true"
,srs: "EPSG:3035"
},
{'buffer':0, 'format':"image/gif", 'isBaseLayer':false,
'transparent':true}
);
Both work in Firefox, IE6 and IE7
