Class Renderer
A base class for renderers that use a collection of one or more symbols to display features in a Layer or graphics in a GraphicsOverlay.
Inheritance
Implements
Namespace: Esri.ArcGISRuntime.Symbology
Assembly: Esri.ArcGISRuntime.dll
Syntax
public abstract class Renderer : INotifyPropertyChangedRemarks
If the renderer contains more than a single symbol, it uses the rules to determine the symbol to apply to each geoelement, based on one or several attribute values. There are three basic types of renderers:
- SimpleRenderer - simple renderers use a single symbol for all geoelements.
- UniqueValueRenderer - unique value renders define a different symbol for each unique value of an attribute.
- ClassBreaksRenderer - class break renderers define a different symbol for each range of numeric values.
To symbolize and display the geoelements, apply the renderer to the Renderer, the Renderer, or the Renderer.
A GraphicsOverlay can contain graphics with different geometry dimensions, such as a MapPoint and Polygon. A Renderer, however, can only provide symbols with one geometry dimension. Therefore, if you apply a renderer to a graphics overlay, only graphics with the specified geometry dimension are displayed. All other graphics are not visible.
If you apply a Symbol directly to a graphic, the symbol displays in preference to the Renderer.
For raster data, rendering is handled by a RasterRenderer.
Properties
| Name | Description |
|---|---|
| RotationExpression | Gets or sets the expression describing how GeoElement's attributes are translated into a rotation to be applied to the GeoElement. |
| RotationType | Gets or sets whether the rotation calculated from the RotationExpression is relative to the screen or map. |
| SceneProperties | Gets or sets the scene properties for the renderer. |
| UnknownJson | Gets unknown data from the source JSON. |
| UnsupportedJson | Gets unsupported data from the source JSON. |
