CreateRectangleGraphicElement Method

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

Syntax

C#
Visual Basic (Declaration)

public GraphicElement CreateRectangleGraphicElement( 
   ILayoutElementContainer elementContainer,
   Envelope envelope,
   CIMPolygonSymbol polygonSymbol
)

Public Function CreateRectangleGraphicElement( _
   ByVal elementContainer As ILayoutElementContainer, _
   ByVal envelope As Envelope, _
   Optional ByVal polygonSymbol As CIMPolygonSymbol _
) As GraphicElement

Parameters

elementContainer: Layout or GroupElement
envelope: 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.
System.InvalidOperationException	Map has reached maximum graphics count limit of 4000 elements. One or more elements cannot be created.
System.InvalidOperationException	Map has reached maximum graphics size limit of 10 MB. One or more elements cannot be created.

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 simple 2D rectangle graphic and apply simple fill and outline symbols.

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

  //Set symbolology, create and add element to layout
  CIMStroke outline = SymbolFactory.Instance.ConstructStroke(ColorFactory.Instance.BlackRGB, 5.0, SimpleLineStyle.Solid);
  CIMPolygonSymbol polySym = SymbolFactory.Instance.ConstructPolygonSymbol(ColorFactory.Instance.GreenRGB, SimpleFillStyle.DiagonalCross, outline);
  GraphicElement recElm = LayoutElementFactory.Instance.CreateRectangleGraphicElement(layout, rec_env, polySym);
  recElm.SetName("New Rectangle");
});
