Render multilayer symbols

Show different kinds of multilayer symbols on a map similar to some pre-defined 2D simple symbol styles.

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)
