Custom Rendering and Industrial Graphics

This section describes how to use the drawingInfo object for a custom rendering with a few examples.

The drawingInfo object contains drawing information for features in a layer with two main components. They are:

• LabelingInfo: Defines the properties used for labeling the layer.

• Renderer: Defines the way a feature is drawn in the map.

  • Simple: It assigns a symbol based on the configuration.

  • ClassBreaks: It symbolizes based on the value of some numeric attribute. It assigns a symbol depending on the range in which this attribute value falls.

  • UniqueValue: It symbolizes features based on one or more matching string attributes.

  • Graphic: It uses Industrial Graphics to symbolize features with point geometries.

A Symbol is a visual representation of the feature (asset). There are different types of symbols: TextSymbol, PictureMarkerSymbol, SimpleLineSymbol, SimpleMarkerSymbol, SimpleFillSymbol,and PictureFillSymbol.
