    LasStretchRendererDefinition Class
    In This Topic
    Represents a LAS stretch renderer definition.
    Object Model
    LasStretchRendererDefinition ClassCIMColorRamp Class
    Syntax
    public class LasStretchRendererDefinition : TinRendererDefinition 
    Public Class LasStretchRendererDefinition 
       Inherits TinRendererDefinition
    Remarks
    Once you define a LAS stretch 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
    Create a LasDatasetLayer with renderers
    //Must be on the QueuedTask.Run()
    
    var lasCP_renderers = new LasDatasetLayerCreationParams(lasDataset);
    lasCP_renderers.Name = "My LAS Layer";
    lasCP_renderers.IsVisible = false;
    
    // create a point elevation renderer
    var ptR = new LasStretchRendererDefinition();
    // accept all defaults
    
    // create a simple edge renderer
    var edgeR = new TinEdgeRendererDefintion();
    // accept all defaults
    
    // add renderers to dictionary
    var l_dict = new Dictionary<SurfaceRendererTarget, TinRendererDefinition>();
    l_dict.Add(SurfaceRendererTarget.Points, ptR);
    l_dict.Add(SurfaceRendererTarget.Edges, edgeR);
    
    // assign dictionary to creation params
    lasCP_renderers.RendererDefinitions = l_dict;
    
    //Create the layer to the LAS dataset
    var lasDatasetLayer_rd = LayerFactory.Instance.CreateLayer<LasDatasetLayer>(lasCP_renderers, map);
    
    LAS Points Elevation Stretch Renderer
    // applies to LAS dataset layers only
    
    var elevLasStretchRendererDef = new LasStretchRendererDefinition(ArcGIS.Core.CIM.LASStretchAttribute.Elevation);
    // accept the defaults for color ramp, etc
    
    if (lasDatasetLayer.CanCreateRenderer(elevLasStretchRendererDef))
    {
      CIMTinRenderer renderer = lasDatasetLayer.CreateRenderer(elevLasStretchRendererDef);
      if (lasDatasetLayer.CanSetRenderer(renderer, SurfaceRendererTarget.Points))
        lasDatasetLayer.SetRenderer(renderer, SurfaceRendererTarget.Points);
    }
    
    
    // OR use a stretch renderer with stretchType standard Deviations
    var elevLasStretchStdDevRendererDef = new LasStretchRendererDefinition(ArcGIS.Core.CIM.LASStretchAttribute.Elevation);
    elevLasStretchStdDevRendererDef.StretchType = LASStretchType.StandardDeviations;
    elevLasStretchStdDevRendererDef.NumberOfStandardDeviations = 2;
    // accept the defaults for color ramp,  etc
    
    if (lasDatasetLayer.CanCreateRenderer(elevLasStretchStdDevRendererDef))
    {
      CIMTinRenderer renderer = lasDatasetLayer.CreateRenderer(elevLasStretchStdDevRendererDef);
      if (lasDatasetLayer.CanSetRenderer(renderer, SurfaceRendererTarget.Points))
        lasDatasetLayer.SetRenderer(renderer, SurfaceRendererTarget.Points);
    }
