CreateEllipseParagraphGraphicElement(ILayoutElementContainer,EllipticArcSegment,String,CIMTextSymbol) Method

Creates a graphic ellipse text element on a layout from an elliptical arc segment geometry with an added parameter to set text symbol. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public GraphicElement CreateEllipseParagraphGraphicElement( 
   ILayoutElementContainer elementContainer,
   EllipticArcSegment ellipse,
   string text,
   CIMTextSymbol textSymbol
)

Public Overloads Function CreateEllipseParagraphGraphicElement( _
   ByVal elementContainer As ILayoutElementContainer, _
   ByVal ellipse As EllipticArcSegment, _
   Optional ByVal text As String, _
   Optional ByVal textSymbol As CIMTextSymbol _
) As GraphicElement

Parameters

elementContainer: Layout or GroupElement
ellipse: EllipticArcSegment
text: String
textSymbol: CIMTextSymbol

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 ellipse paragraph text with basic text settings and optionally a modified border.

//Construct on the worker thread
await QueuedTask.Run(() =>
{
  //Build geometry
  Coordinate2D center = new Coordinate2D(4.5, 2.75);
  EllipticArcBuilder eabElp = new EllipticArcBuilder(center, 0, 1, 0.45, esriArcOrientation.esriArcClockwise);
  EllipticArcSegment ellipse = eabElp.ToSegment();

  //Set symbolology, create and add element to layout
  CIMTextSymbol sym = SymbolFactory.Instance.ConstructTextSymbol(ColorFactory.Instance.BlueRGB, 10, "Arial", "Regular");
  string text = "Ellipse, ellipse, ellipse, ellipse, ellipse, ellipse, ellipse, ellipse, ellipse, ellipse, ellipse, ellipse";
  GraphicElement elpTxtElm = LayoutElementFactory.Instance.CreateEllipseParagraphGraphicElement(layout, ellipse, text, sym);
  elpTxtElm.SetName("New Ellipse Text");

  //(Optionally) Modify paragraph border 
  CIMGraphic elpTxtGra = elpTxtElm.GetGraphic();
  CIMParagraphTextGraphic cimElpTxtGra = elpTxtGra as CIMParagraphTextGraphic;
  cimElpTxtGra.Frame.BorderSymbol = new CIMSymbolReference();
  cimElpTxtGra.Frame.BorderSymbol.Symbol = SymbolFactory.Instance.ConstructLineSymbol(ColorFactory.Instance.GreyRGB, 1.0, SimpleLineStyle.Solid);
  elpTxtElm.SetGraphic(elpTxtGra);
});
