LasUniqueValueRendererDefinition Constructor(LasAttributeType,Boolean,CIMSymbolReference,Double,CIMColorRamp)

In This Topic

Creates a unique value renderer definition to draw points in a LAS dataset layer.

Syntax

Visual Basic (Declaration)
C#

Public Function New( _
   ByVal attributeType As LasAttributeType, _
   Optional ByVal modulateUsingItensity As Boolean, _
   Optional ByVal symbolTemplate As CIMSymbolReference, _
   Optional ByVal symbolScaleFactor As Double, _
   Optional ByVal colorRamp As CIMColorRamp _
)

public LasUniqueValueRendererDefinition( 
   LasAttributeType attributeType,
   bool modulateUsingItensity,
   CIMSymbolReference symbolTemplate,
   double symbolScaleFactor,
   CIMColorRamp colorRamp
)

Parameters

attributeType: The attribute to define the unique values.
modulateUsingItensity: (Optional) Flag indicating whether or not to modulate using intensity.
symbolTemplate: (Optional) Symbol template for the classes.
symbolScaleFactor: (Optional) The symbol scale factor assigned to the symbols. Valid values are between -4.0 and 4.0.
colorRamp: (Optional) Color ramp to apply to those classes.

Remarks

Only the following values are valid for - LasAttributeType.Classification, LasAttributeType.ReturnNumber, LasAttributeType.NumberOfReturns, LasAttributeType.PointSourceID or LasAttributeType.UserData.

The symbol size is calculated as Math.Pow(2, symbolScaleFactor).

Example

LAS Points Classification Unique Value Renderer

{
  var lasPointsClassificationRendererDef = new LasUniqueValueRendererDefinition(LasAttributeType.Classification);
  // accept the defaults for color ramp, symbolTemplate, symbol scale factor

  if (lasDatasetLayer == null)
    return;
  // Note: Needs QueuedTask to run
  {
    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

{
  var lasPointsReturnsRendererDef = new LasUniqueValueRendererDefinition(LasAttributeType.ReturnNumber);
  lasPointsReturnsRendererDef.ModulateUsingIntensity = true;
  lasPointsReturnsRendererDef.SymbolScaleFactor = 1.0;
  // accept the defaults for color ramp, symbolTemplate
  // Note: Needs QueuedTask to run
  {
    if (lasDatasetLayer.CanCreateRenderer(lasPointsReturnsRendererDef))
    {
      CIMTinRenderer renderer = lasDatasetLayer.CreateRenderer(lasPointsReturnsRendererDef);
      if (lasDatasetLayer.CanSetRenderer(renderer, SurfaceRendererTarget.Points))
        lasDatasetLayer.SetRenderer(renderer, SurfaceRendererTarget.Points);
    }
  }
}
