Symbols and renderers

Symbols define the non-geographic aspects of a graphic's appearance, such as color, border width, transparency, and so on. The ArcGIS Runtime SDK ArcGIS Runtime SDK for WPF includes many symbol classes, each of which allows you to specify symbology in a unique way. Each symbol type is also specific to one geometry type (that is, point, line, or polygon).

Renderers define one or more symbols to apply to a graphics layer. The symbol applied to each graphic depends on the graphic's attributes. The renderer specifies which attribute values correspond to which symbol.

Symbol types

The available symbols and the geometries to which they apply are summarized in the following table:

Symbol	Geometry	Description
SimpleMarkerSymbol	Point	Symbolizes points with simple shapes
PictureMarkerSymbol	Point	Symbolizes points with images
SimpleLineSymbol	Polyline	Symbolizes lines with pre-defined styles
CartographicLineSymbol	Polyline	Symbolizes lines with custom styles
SimpleFillSymbol	Polygon	Fills polygons with a WPF Brush
PictureFillSymbol	Polygon	Fills polygons with images
