VisvalingamShapeSimplifier Class
Specifies the Visvalingam shape simplification algorithm.
Namespace: DevExpress.Xpf.Map
Assembly: DevExpress.Xpf.Map.v24.2.dll
NuGet Package: DevExpress.Wpf.Map
Declaration
Remarks
The following example shows how to use VisvalingamShapeSimplifier to simplify vector layer items.
private void SimpleButton_Click(object sender, RoutedEventArgs e) {
VisvalingamShapeSimplifier simplifier = new VisvalingamShapeSimplifier();
simplifier.Simplify(adapter.DisplayItems, 50);
}
The Map control also provides the built-in DouglasPeuckerShapeSimplifier you can use instead of VisvalingamShapeSimplifier. The Douglas-Peucker algorithm provides greater smoothness of the resulting polyline while the Visvalingam algorithm demonstrates better performance when you process a polyline with a large number of vertices.
