All,
I found a snippet for creating callout text symbol below. What I need is to add callout text symbols to all selected features in layout. How do I use my selected feature centroid x, y with the codes below ? Thank you for your help.
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; }); }
