    LasUniqueValueRendererDefinition Class
    In This Topic
    Represents a unique value renderer definition for a LAS dataset layer.
    Object Model
    LasUniqueValueRendererDefinition ClassCIMColorRamp ClassCIMSymbolReference Class
    Syntax
    public class LasUniqueValueRendererDefinition : TinUniqueValueRendererDefinition 
    Public Class LasUniqueValueRendererDefinition 
       Inherits TinUniqueValueRendererDefinition
    Remarks
    Once you define a renderer, you can call a surface layer's CanCreateRenderer, CreateRenderer, CanSetRenderer and SetRenderer methods to create and assign a renderer to a surface layer.
    Example
    LAS Points Classification Unique Value Renderer
    // applies to LAS dataset layers only
    
    var lasPointsClassificationRendererDef = new LasUniqueValueRendererDefinition(LasAttributeType.Classification);
    // accept the defaults for color ramp, symbolTemplate, symbol scale factor
    
    var lasDatasetLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<LasDatasetLayer>().FirstOrDefault();
    if (lasDatasetLayer == null)
      return;
    
    if (lasDatasetLayer.CanCreateRenderer(lasPointsClassificationRendererDef))
    {
      CIMTinRenderer renderer = lasDatasetLayer.CreateRenderer(lasPointsClassificationRendererDef);
      if (lasDatasetLayer.CanSetRenderer(renderer, SurfaceRendererTarget.Points))
        lasDatasetLayer.SetRenderer(renderer, SurfaceRendererTarget.Points);
    }
    LAS Points Returns Unique Value Renderer
    // applies to LAS dataset layers only
    
    var lasPointsReturnsRendererDef = new LasUniqueValueRendererDefinition(LasAttributeType.ReturnNumber);
    lasPointsReturnsRendererDef.ModulateUsingIntensity = true;
    lasPointsReturnsRendererDef.SymbolScaleFactor = 1.0;
    // accept the defaults for color ramp, symbolTemplate
    
    if (lasDatasetLayer.CanCreateRenderer(lasPointsReturnsRendererDef))
    {
      CIMTinRenderer renderer = lasDatasetLayer.CreateRenderer(lasPointsReturnsRendererDef);
      if (lasDatasetLayer.CanSetRenderer(renderer, SurfaceRendererTarget.Points))
        lasDatasetLayer.SetRenderer(renderer, SurfaceRendererTarget.Points);
    }
