[OpenLayers-Dev] displaying data at multiple levels through open layers wms

[Arnd Wippermann]

Hi,

perhaps you could do something like this:

map.events.register("zoomend", map, addZoomLevel);

function addZoomLevel{
    yourWMSlayer.mergeNewParams(zoomlevel:map.getZoom());
}

This should add the parameter ZOOMLEVEL=Number to the WMS request.

Mit freundlichen Grüssen
