listen to the zoom event and redraw the feature with the new styleMap, where
the pointRadius is a function of the zoom level:
 
new OpenLayers.StyleMap({
    "default": OpenLayers.Util.applyDefaults({
        pointRadius: faktor*map.getZoom()
    }, OpenLayers.Feature.Vector.style["default"]
});

Betreff: [OpenLayers-Users] Dynamically Sized Points With Styles


I was wondering if it is possible to dynamically resize a point based on the
zoom level of the map.

With the example at
http://www.openlayers.org/dev/examples/styles-unique.html, can we make the
points change their radius as we zoom in?  I'd like to keep the circles the
same relative size to the underlying map layer.

Thanks,

- Chris
