VectorLayer.Colorizer Property

Gets or sets the colorizer for the vector layer.

Namespace: DevExpress.Xpf.Map

Assembly: DevExpress.Xpf.Map.v18.2.dll

Declaration

C#

public MapColorizer Colorizer { get; set; }

VB.NET

Public Property Colorizer As MapColorizer

Property Value

Type	Description
MapColorizer	A MapColorizer class descendant object.

Example

This example demonstrates how to paint map contours loaded from a Shapefile (Countries.shp) using the graph colorizer.

To accomplish this task, create a graph colorizer (the GraphColorizer object) and assign it to the VectorLayer.Colorizer property.

And finally, specify the desired set of colors in the ColorCollection object that is accessed via the MapColorizer.Colors property.
