CreateSimpleTextGraphic Method (GraphicFactory)

In This Topic

Creates a text graphic based on the input geometry, symbol, and text. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public CIMTextGraphicBase CreateSimpleTextGraphic( 
   TextType textType,
   Geometry geometry,
   CIMTextSymbol textSymbol,
   string text
)

Public Function CreateSimpleTextGraphic( _
   ByVal textType As TextType, _
   ByVal geometry As Geometry, _
   Optional ByVal textSymbol As CIMTextSymbol, _
   Optional ByVal text As String _
) As CIMTextGraphicBase

Parameters

textType: The type of text graphic to create
geometry: The geometry for the resulting graphic
textSymbol: The text symbol to be used with the graphic (optional)
text: The text string (optional)

Return Value

A ArcGIS.Core.CIM.CIMTextGraphicBase

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

For:

TextType.PointText use a point
TextType.SplinedText use a polyline (straight or curved)
TextType.CircleParagraph use a circle (polygon)
TextType.EllipseParagraph use an ellipse (polygon)
TextType.RectangleParagraph use an envelope
TextType.PolygonParagraph use a polygon

For TextType.PointText and TextType.SplinedText, cast the returned CIMTextGraphicBase to ArcGIS.Core.CIM.CIMTextGraphic. For all paragraph text types cast to ArcGIS.Core.CIM.CIMParagraphTextGraphic.

Example

Create Circle Text Graphic

//Must be on QueuedTask.Run(() => { ...

//Build geometry
Coordinate2D center = new Coordinate2D(4.5, 4);
var eabCir = new EllipticArcBuilderEx(center, 0.5, ArcOrientation.ArcClockwise);
var cir = eabCir.ToSegment();

var poly = PolygonBuilderEx.CreatePolygon(
  PolylineBuilderEx.CreatePolyline(cir, AttributeFlags.AllAttributes));

//Set symbolology, create and add element to layout
CIMTextSymbol sym = SymbolFactory.Instance.ConstructTextSymbol(
  ColorFactory.Instance.GreenRGB, 10, "Arial", "Regular");
string text = "Circle, circle, circle";

var graphic = GraphicFactory.Instance.CreateSimpleTextGraphic(
  TextType.CircleParagraph, poly, sym, text);

//Make an element to add to GraphicsLayer or Layout
//var ge = ElementFactory.Instance.CreateGraphicElement(container, graphic,
//  "New Circle Text", true);

Create Bezier Graphic

//Must be on QueuedTask.Run(() => { ...

//Build geometry
Coordinate2D pt1 = new Coordinate2D(3.5, 7.5);
Coordinate2D pt2 = new Coordinate2D(4.16, 8);
Coordinate2D pt3 = new Coordinate2D(4.83, 7.1);
Coordinate2D pt4 = new Coordinate2D(5.5, 7.5);
var bez = new CubicBezierBuilderEx(pt1, pt2, pt3, pt4);
var bezSeg = bez.ToSegment();
Polyline bezPl = PolylineBuilderEx.CreatePolyline(bezSeg, AttributeFlags.AllAttributes);

//Set symbolology, create and add element to layout
CIMTextSymbol sym = SymbolFactory.Instance.ConstructTextSymbol(
      ColorFactory.Instance.BlackRGB, 24, "Comic Sans MS", "Regular");

var graphic = GraphicFactory.Instance.CreateSimpleTextGraphic(
  TextType.SplinedText, bezPl, sym, "Splined text");

//Make an element to add to GraphicsLayer or Layout
//var ge = ElementFactory.Instance.CreateGraphicElement(container, graphic);
