TGIS_AggregatorShapeReduction class
DK11 for ActiveX | TatukGIS_XDK11.TGIS_AggregatorShapeReduction | Classes | Methods | Properties
This class implements the aggregation method based on shape reduction. This method is designed to work with dense point data.
Syntax

Aggregation is available through the Layer Properties Control in General node and is stored to the project file.
Example
The recommended way to construct an aggregator is to use TGIS_DynamicAggregatorFactory. It is also possible to directly assign an instance of a class that inherits from TGIS_AggregatorAbstract.
VisualBasic
// attach aggregator Dim factory = new TGIS_DynamicAggregatorFactory() ; layer.DynamicAggregator = factory.CreateInstance( "ShapeReduction", layer ) ; // detach aggregator layer.DynamicAggregator = Nothing ;
