CreatePredefinedShapeGraphicElement(IElementContainer,PredefinedShape,MapPoint,Double,Double,CIMPolygonSymbol,String,Boolean,ElementInfo) Method

In This Topic

Create a polygon graphic of the specified PredefinedShape using the provided location, optional size dimensions, and symbol. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

Public Overloads Function CreatePredefinedShapeGraphicElement( _
   ByVal elementContainer As IElementContainer, _
   ByVal shapeType As PredefinedShape, _
   ByVal location As MapPoint, _
   Optional ByVal width As Double, _
   Optional ByVal height As Double, _
   Optional ByVal polySymbol As CIMPolygonSymbol, _
   Optional ByVal elementName As String, _
   Optional ByVal select As Boolean, _
   Optional ByVal elementInfo As ElementInfo _
) As GraphicElement

Parameters

elementContainer: The parent element container
shapeType: The shape type of the graphic
location: The location of the graphic
width: The width of the graphic bounding box (optional)
height: The height of the graphic bounding box (optional)
polySymbol: The symbol to be used with the graphic (optional)
elementName: An element name (optional)
select: Select after create flag (default is true) (optional)
elementInfo: Additional element properties (optional)

Return Value

GraphicElement

Exceptions

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

Remarks

If neither a width or height is provided, the dimensions of the graphic bounding box will use a predefined system default. If only one of width or height is provided then the dimensions will be assumed to be equal. Negative width and height values will be treated the same as if they were missing. When generating a circle (i.e. PredefinedShape.Circle) width is used as the circle diameter. When generating an ellipse (i.e. PredefinedShape.Ellipse) width and height are assumed to be the length of the two axis - major/minor depending on which dimension is the longest.

Example

Create rectangle graphic with simple symbology

//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);
  //At 2.x - Envelope rec_env = EnvelopeBuilder.CreateEnvelope(rec_ll, rec_ur);
  Envelope rec_env = EnvelopeBuilderEx.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);

  //At 2.x - GraphicElement recElm =
  //           LayoutElementFactory.Instance.CreateRectangleGraphicElement(
  //                                                  layout, rec_env, polySym);
  //         recElm.SetName("New Rectangle");
  //
  GraphicElement recElm = ElementFactory.Instance.CreateGraphicElement(
    container, rec_env, polySym, "New Rectangle");
  //Or use Predefined shape
  GraphicElement recElm2 = ElementFactory.Instance.CreatePredefinedShapeGraphicElement(
                            container, PredefinedShape.Rectangle, rec_env, polySym, 
                            "New Rectangle2");
});
