Creates a simple line callout text symbol

Creates a simple line callout text symbol. The CIMSimpleLineCallout created is a dash-dot-dash line symbol with an offset of 10 from the geometry being labeled. 

private static Task<CIMTextSymbol> CreateSimpleLineCalloutAsync()
{
    return QueuedTask.Run<CIMTextSymbol>(() => { //create a text symbol var textSymbol = SymbolFactory.Instance.ConstructTextSymbol(ColorFactory.Instance.BlackRGB, 10, "Verdana", "Regular"); //Create a line call out var lineCalloutSymbol = new CIMSimpleLineCallout(); //Get a line symbol var lineSymbol = SymbolFactory.Instance.ConstructLineSymbol(ColorFactory.Instance.BlackRGB, 1, SimpleLineStyle.DashDotDot); //assign the line symbol to the callout lineCalloutSymbol.LineSymbol = lineSymbol; //Offset for the text textSymbol.OffsetX = 10; textSymbol.OffsetY = 10; //Assign the callout to the text symbol textSymbol.Callout = lineCalloutSymbol; return textSymbol; }); }

Creates a balloon callout text symbol

Creates a black banner balloon callout text symbol. The CIMBalloonCallout created is a rectangular polygon with rounded corners. 

private static Task<CIMTextSymbol> CreateBalloonCalloutAsync()
{
    return QueuedTask.Run<CIMTextSymbol>(() => { //create a text symbol var textSymbol = SymbolFactory.Instance.ConstructTextSymbol(ColorFactory.Instance.WhiteRGB, 11, "Corbel", "Regular"); //A balloon callout var balloonCallout = new CIMBalloonCallout(); //set the callout's style balloonCallout.BalloonStyle = BalloonCalloutStyle.RoundedRectangle; //Create a solid fill polygon symbol for the callout. var polySymbol = SymbolFactory.Instance.ConstructPolygonSymbol(ColorFactory.Instance.BlackRGB, SimpleFillStyle.Solid); //Set the callout's background to be the black polygon symbol balloonCallout.BackgroundSymbol = polySymbol; //margin inside the callout to place the text balloonCallout.Margin = new CIMTextMargin { Left = 5, Right = 5, Bottom = 5, Top = 5 }; //assign the callout to the text symbol's callout property textSymbol.Callout = balloonCallout; return textSymbol; }); }

Creates a point callout text symbol

Creates a highway shield callout text symbol. The CIMPointSymbolCallout created is a highway shield point symbol from the ArcGIS 2D style. 

private static Task<CIMTextSymbol> CreatePointCallOutAsync()           
{
    return QueuedTask.Run<CIMTextSymbol>(() => { //create a text symbol var textSymbol = SymbolFactory.Instance.ConstructTextSymbol(ColorFactory.Instance.WhiteRGB, 6, "Tahoma", "Bold"); //Create a call out var shieldCalloutSymbol = new CIMPointSymbolCallout(); //Get a Shield symbolStyleItem from ArcGIS 2D StyleProjectitem var symbolStyleItem = GetPointSymbol("ArcGIS 2D", "Shield 1"); //assign the point symbol (Highway shield) to the callout shieldCalloutSymbol.PointSymbol = symbolStyleItem.Symbol as CIMPointSymbol; shieldCalloutSymbol.PointSymbol.SetSize(18.0); //set symbol size //Assign the callout to the text symbol textSymbol.Callout = shieldCalloutSymbol; return textSymbol; }); }

Creates a background callout text symbol

Creates a solid fill background text symbol with an Accent bar and leader line. The CIMBackgroundCallout created has a solid fill aqua polygon, with a black dash-dot-dash leader line and a solid accent bar. 

private static Task<CIMTextSymbol> CreateBackgroundCalloutAsync()
{
    return QueuedTask.Run<CIMTextSymbol>(() => { var textSymbol = SymbolFactory.Instance.ConstructTextSymbol(ColorFactory.Instance.BlackRGB, 8, "Tahoma", "Bold"); //Create a call out var backgroundCalloutSymbol = new CIMBackgroundCallout(); //Leader line //Get a line symbol var lineSymbol = SymbolFactory.Instance.ConstructLineSymbol(ColorFactory.Instance.BlackRGB, 1, SimpleLineStyle.DashDotDot); //Create a solid fill polygon symbol for the callout. var aquaBackground = ColorFactory.Instance.CreateRGBColor(190, 255, 232, 100); var polySymbol = SymbolFactory.Instance.ConstructPolygonSymbol(aquaBackground, SimpleFillStyle.Solid); //assign the line to the callout backgroundCalloutSymbol.LeaderLineSymbol = lineSymbol; //Offset for the text textSymbol.OffsetX = 10; textSymbol.OffsetY = 10; //Assign the polygon to the background callout backgroundCalloutSymbol.BackgroundSymbol = polySymbol; //Accent bar var accentSymbol = SymbolFactory.Instance.ConstructLineSymbol(ColorFactory.Instance.BlackRGB, 2, SimpleLineStyle.Solid); backgroundCalloutSymbol.AccentBarSymbol = accentSymbol; //Set margins for the callout backgroundCalloutSymbol.Margin = new CIMTextMargin { Left = 5, Right = 5, Top = 5, Bottom = 5 }; //assign the callout to the textSymbol textSymbol.Callout = backgroundCalloutSymbol; return textSymbol; }); }
