VisvalingamShapeSimplifier Class

Specifies the Visvalingam shape simplification algorithm.

Namespace: DevExpress.XtraMap

Assembly: DevExpress.XtraMap.v20.1.dll

NuGet Package: DevExpress.Win.Map

Declaration

C#

public class VisvalingamShapeSimplifier :
    ShapeSimplifierBase

VB.NET

Public Class VisvalingamShapeSimplifier
    Inherits ShapeSimplifierBase

Remarks

You can use the VisvalingamShapeSimplifier instance to pass as the first parameter into the MapEditor.SimplifyItems(ShapeSimplifierBase, IEnumerable<MapItem>, Double) method.

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.
