How do I construct a symbol with text within it?

ViktorSafar — Wed, 20 Sep 2023 08:16:33 GMT

I want to create a CIMSymbol that will be used in a unique value class renderer. The symbol should be a circle with red fill and the letter R in it.

This is what I have but the symbol comes out as empty and the Symbology tab shows "symbol has inconsistent geometry logic"

I have tried to use the Symbology tab to see what I can fix to make it work but it appears that the only way to make that error go away is to add a global effect to the symbol? And while the error went away, the symbol still did not render.

I have also tried to play with the CIM Viewer to see what I can do but have not managed to find anything.

Are you potentially replying on the wrong thread?

I have actually figured it out by using the Symbology pane and the CIM Viewer and lots of back and forth

double size = 10; CIMColor fillColor = ColorFactory.Instance.RedRGB; var textSymbol = SymbolFactory.Instance.ConstructTextSymbol(ColorFactory.Instance.BlackRGB, size); textSymbol.VerticalAlignment = VerticalAlignment.Center; textSymbol.HorizontalAlignment = HorizontalAlignment.Center; var fill = SymbolFactory.Instance.ConstructSolidFill(fillColor); var marker = SymbolFactory.Instance.ConstructMarker() as CIMVectorMarker; marker.MarkerPlacement = new CIMMarkerPlacementPolygonCenter(); marker.MarkerGraphics[0].Geometry = new PointN().ToCoreGeometry<MapPoint>(); marker.MarkerGraphics[0].Symbol = textSymbol; marker.MarkerGraphics[0].TextString = "R"; List<CIMSymbolLayer> symbolLayers = new List<CIMSymbolLayer> { marker, fill }; var symbol = new CIMPointSymbol() { Effects = new List<CIMGeometricEffect> { new CIMGeometricEffectRegularPolygon() { Radius = size } }.ToArray(), SymbolLayers = symbolLayers.ToArray() }; symbol.SetSize(size); return symbol;
