LasPointClassBreaksRendererDefinition Constructor(ClassificationMethod,Int32,CIMSymbolReference,Double,CIMColorRamp)

In This Topic

Create a class breaks renderer definition to draw points in a LAS dataset layer.

Syntax

C#
Visual Basic (Declaration)

public LasPointClassBreaksRendererDefinition( 
   ClassificationMethod classificationMethod,
   int breakCount,
   CIMSymbolReference symbolTemplate,
   double symbolScaleFactor,
   CIMColorRamp colorRamp
)

Public Function New( _
   ByVal classificationMethod As ClassificationMethod, _
   Optional ByVal breakCount As Integer, _
   Optional ByVal symbolTemplate As CIMSymbolReference, _
   Optional ByVal symbolScaleFactor As Double, _
   Optional ByVal colorRamp As CIMColorRamp _
)

Parameters

classificationMethod: Classification method.
breakCount: (Optional) Number of breaks. (Default value = 9)
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

A LasPointClassBreaksRendererDefinition has a fixed CursorType of ArcGIS.Core.CIM.TerrainDrawCursorType.TerrainPointElevation and is only applicable to a LAS dataset layer.

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

Example

LAS Points Classified Elevation Renderer

// applies to LAS dataset layers only

var lasPointsClassBreaksRendererDef = new LasPointClassBreaksRendererDefinition();
lasPointsClassBreaksRendererDef.ClassificationMethod = ClassificationMethod.NaturalBreaks;
lasPointsClassBreaksRendererDef.ModulateUsingIntensity = true;
// increase the symbol size by a factor
lasPointsClassBreaksRendererDef.SymbolScaleFactor = 1.0;

if (lasDatasetLayer.CanCreateRenderer(lasPointsClassBreaksRendererDef))
{
  CIMTinRenderer renderer = lasDatasetLayer.CreateRenderer(lasPointsClassBreaksRendererDef);
  if (lasDatasetLayer.CanSetRenderer(renderer, SurfaceRendererTarget.Points))
    lasDatasetLayer.SetRenderer(renderer, SurfaceRendererTarget.Points);
}

Requirements

Target Platforms: Windows 11, Windows 10

ArcGIS Pro version: 3.2 or higher.
