Optional event: Modifying a marker cluster

The event "Modification of a marker cluster" is executed when the Map control containing clusters is displayed. This event is executed for each marker cluster found. In particular, it allows you to modify the display of the cluster.

This event has the following format:

PROCÉDURE ModifCluster(tabMarqueur est un tableau de Marqueurs)

where tabMarker is an array containing the variables of type Marker associated with the cluster.
This event can return:

nothing or an empty string: in this case, the Default display of the cluster will be used.
the path of an Image: this Image will be used to represent the cluster.
an variable of type MarkerImage, allowing to customize the image of the cluster.

In WEBDEV, this event is a browser event only.
