markerclusterer: anchor offset for cluster icons

Question

I'm trying to slightly offset cluster icons created by the Google Maps Markerclusterer (V3). Short of modifying the existing code, I can't find a way to do this. Does anybody have an idea?

The Styles object in which you can provide a custom image URL accepts an anchor property, but this is to offset the generated marker item count.

Thanks!

The proper way to do it is to adjust the anchorIcon property like this:

var clusterStyles = [
{
    height: 64,
    width: 53,
    anchorIcon: [20, 140]
},
{
    height: 64,
    width: 53,
    anchorIcon: [20, 140]
},
{
    height: 64,
    width: 53,
    anchorIcon: [20, 140]
}
];

var mcOptions = {
    styles: clusterStyles
};

var markerCluster = new MarkerClusterer(map, markers, mcOptions);
