Use case

Allows you to customize a graphic with a multilayer symbol. For example, you may want more customizable symbols than the one that is provided with the API to display a unique representation of a landmark.

How to use the sample

The sample loads multilayer symbols for points, polylines, and polygons.

How it works

  1. Create multilayer symbols for each predefined 2D simple symbol style.
    • For multilayer point symbols, use the MultilayerPoint constructor.
    • For multilayer polyline symbols, use the MultiLayerPolyline constructor.
    • For multilayer polygon symbols, use the MultiLayerPolygon constructor.
  2. Create graphics by passing in a geometry and the associated symbol.
  3. Add graphics to the graphics overlay with graphicsOverlay.Graphics.Add(graphic)
