[OpenLayers-Users] overview control

[huub fleuren]

Hi Tim,

Yes I see now were i got confused. Thanks for clarifying the example.

I' using this now:
  var options2 = {
    size:new OpenLayers.Size(100,130),
    minRatio:8,
    maxRatio:32,
    mapOptions : {layers: [overviewlayer.clone()],maxResolution: 2500}
  };

  var overview = new OpenLayers.Control.OverviewMap(options2);


Regards, Huub
