CreatePolygonGraphicElement(ILayoutElementContainer,Envelope,CIMPolygonSymbol) Method

Creates a graphic polygon element on a layout from an envelope geometry. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

GraphicElement CreatePolygonGraphicElement( 
   ILayoutElementContainer elementContainer,
   Envelope env,
   CIMPolygonSymbol polygonSymbol
)

Overloads Function CreatePolygonGraphicElement( _
   ByVal elementContainer As ILayoutElementContainer, _
   ByVal env As Envelope, _
   Optional ByVal polygonSymbol As CIMPolygonSymbol _
) As GraphicElement

Parameters

elementContainer: Layout or GroupElement
env: Envelope
polygonSymbol: CIMPolygonSymbol

Return Value

Returns a GraphicElement.

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run.

Remarks

If the element container is a Layout then the element gets added to the root level of the layout TOC at the top most position. If the element container is a GroupElement then it gets added to the group at the topmost position.

Example

//Create a polygon graphic using an envelope with simple line and fill styles.

//Construct on the worker thread
await QueuedTask.Run(() =>
{
  //Build 2D envelope
  Coordinate2D env_ll = new Coordinate2D(1.0, 4.75);
  Coordinate2D env_ur = new Coordinate2D(3.0, 5.75);
  Envelope env = EnvelopeBuilder.CreateEnvelope(env_ll, env_ur);

  //Set symbolology, create and add element to layout
  CIMStroke outline = SymbolFactory.Instance.ConstructStroke(ColorFactory.Instance.BlueRGB, 2.0, SimpleLineStyle.DashDotDot);
  CIMPolygonSymbol polySym = SymbolFactory.Instance.ConstructPolygonSymbol(ColorFactory.Instance.RedRGB, SimpleFillStyle.ForwardDiagonal, outline);
  GraphicElement polyElm = LayoutElementFactory.Instance.CreatePolygonGraphicElement(layout, env, polySym);
  polyElm.SetName("New Polygon");
});

Requirements
