I'm trying to add text overlay to map but it seems that Placement of a CIMTextGraphic is totally ignored, so text always anchored to geometry by bottom left corner. On image below letters 'A'...'I' are drawn using all possible values of Anchor enum as value of Placement property:

As you can see all letters are drawn at the same point although I set different anchors for them. I use MapPoint (orange circles) as Geometry for CIMTextSymbol. Is there a workaround for this problem? And when it will be fixed?

Hi Max

You will have to set the alignment on the underlying text symbol.  So something like this:

 //Create a simple text symbol
                textSymbol = SymbolFactory.Instance.ConstructTextSymbol(ColorFactory.Instance.BlackRGB, 8.5, "Corbel", "Regular");
//alignement properties               
textSymbol.HorizontalAlignment = HorizontalAlignment.Left;
                textSymbol.VerticalAlignment = VerticalAlignment.Bottom;

                //Sets the geometry of the text graphic
                textGraphic.Shape = geometry;
                //Sets the text string to use in the text graphic
                textGraphic.Text = "This is my line";

                //textGraphic.Placement = Anchor.BottomMidPoint;
                //Sets symbol to use to draw the text graphic
                textGraphic.Symbol = textSymbol.MakeSymbolReference();
                //Draw the overlay text graphic
                _graphic = this.ActiveMapView.AddOverlay(textGraphic);

Thanks
