[OpenLayers-Users] Cluster strategy on markers

[Ivan Grcic]

Hi...so you just use vector layer with points that represents
markers...i think this might be usefull to you:

var style= new OpenLayers.Style({
		externalGraphic: "${getIcon}",
                graphicWidth:"${getSize}",
		graphicHeight:"${getSize}",
		graphicOpacity:0.90,
		cursor:'pointer'
               ...
               ...
     }, {
        context: {
          getSize: function(feature) {
			return __getClusterIconSize(feature);
        },
		  getIcon: function(feature){
			return __getClusterIcon(feature);
		}
		}
     });

cheers!
