public class IlvMapPointLabel extends IlvMapLabelingLabel
IlvMapPoints
. For each IlvMapPoint
passed as parameter, the placeLabels()
method will try 4 candidate positions about the point (ordered according to general label quality
criteria, North-East, South-East, North-West, South-West). The first candidate that does not intersect
previously placed labels is chosen. Otherwise this label is not drawn.Modifier and Type | Class and Description |
