The "Modify a marker cluster" event is executed when a Map control containing clusters is displayed. This event is executed for each marker cluster found. It is mainly used to change how the cluster is displayed.
This event has the following format:
PROCEDURE ModifCluster(arrMarker is array of Markers)
where arrMarker is an array containing variables of type Marker associated with the cluster.
This event can return:
  • nothing or an empty string: in this case, the default appearance of the cluster will be used.
  • an image path: this image will be used to represent the cluster.
  • a variable of type MarkerImage, used to customize the cluster image.
