Class Renderer

Syntax

public abstract class Renderer : INotifyPropertyChanged

Remarks

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.

Methods

Name	Description
Clone()	Returns a clone of the Renderer.
FromJson(String)	Returns the json representation of the renderer
GetSymbol(GeoElement)	Returns the symbol the renderer uses to represent the supplied GeoElement.
GetSymbol(GeoElement, Boolean)	Returns the symbol used to visualize the given GeoElement with override attributes from renderer.
ToJson()	Returns the json representation of the renderer

Events

Name	Description
PropertyChanged	Occurs when a property value changes.
