Re: [OpenLayers-Users] IE6 requests FORMAT=image/GIF - solved

Ok,

I got it. Didn't use the opacity setting.
var ronko2 = new OpenLayers.Layer.WMS(
            "Kaava-alueet", 
"http://karsamaki.digikartta.net/asemakaavat/wms",
                {layers: 'dikanet:karsa_region,dikanet:karsa_text', 
format:'image/gif',transparent:true}, {maxExtent: bounds, opacity: 0.5,
isBaseLayer:false, resolutions: [5.66154, 2.8308, 1.132308, 0.56615, 
0.28308, 0.1132308]});
And that setting overrides the default SLD-setting, right? Now it works in IE6 as well as in the other browsers.
Sorry for thinking aloud on this list. :-[

Sorry,
that isn't totally right. That layer definition doesn't work in any 
browser of mine. The key factor is having it as an overlay layer. As a 
base layer it works. So it seems that the only solution to have an 
overlay layer with regions' opacity set, is to use png and 
'alpha:true'-setting. I can provide you a live example of this problem, 
if you like. If this is true, I'll be better off by just announcing: 
"Dont try this with IE6.". Yet so many people are still using Windows 
2000 and IE.

Hi Christopher and others,

I have this in my code and can't get the opacity work in IE6.

var ronko2 = new OpenLayers.Layer.WMS(
            "Kaava-alueet", 
"http://karsamaki.digikartta.net/asemakaavat/wms",
                {layers: 'dikanet:karsa_region,dikanet:karsa_text', 
format:'image/gif',transparent:true}, {maxExtent: bounds, 
isBaseLayer:false, resolutions: [5.66154, 2.8308, 1.132308, 0.56615, 
0.28308, 0.1132308]});

What's wrong with the code? OL is 2.6. Wms-server is Geoserver and in 
there, the SLD says that the opacity of the polygons should be 0.2. 
Works in IE7 and FF2-3.

And that would work in IE6 with layer format to set image/gif?

Should.
