GraphColorizer Class

Represents the Graph colorizer that tries to paint shapes that have a common border using different colors.

Namespace: DevExpress.Xpf.Map

Assembly: DevExpress.Xpf.Map.v24.2.dll

NuGet Package: DevExpress.Wpf.Map

Declaration

C#

public class GraphColorizer :
    MapColorizer

VB.NET

Public Class GraphColorizer
    Inherits MapColorizer

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.

View Example

MainWindow.xaml

<dxm:VectorLayer.Colorizer>
    <dxm:GraphColorizer>
        <dxm:GraphColorizer.Colors>
            <Color>#D6864E</Color>
            <Color>#C56450</Color>
            <Color>#BA4D51</Color>

            <Color>#799689</Color>
            <Color>#A2A875</Color>
        </dxm:GraphColorizer.Colors>
