Drawing : Fill between 2 vectors

[TradeForge]

Hi Ninja's;

I'm trying to fill a zone between two vectors with the following function on a custom drawing tool, but, it'doesn't show at all, may you tell me if the function is correct please?

private void FillBands(Vector2 startVector, Vector2 endVector)
  {
      RenderTarget.AntialiasMode = SharpDX.Direct2D1.AntialiasMode.PerPrimitive;


      SharpDX.Direct2D1.PathGeometry polyGeo = new SharpDX.Direct2D1.PathGeometry(Core.Globals.D2DFactory);
      SharpDX.Direct2D1.GeometrySink geoSink = polyGeo.Open();
  
    
      geoSink.BeginFigure(startVector, SharpDX.Direct2D1.FigureBegin.Filled);
      geoSink.SetFillMode(SharpDX.Direct2D1.FillMode.Winding);

      geoSink.AddLine(endVector);
      geoSink.EndFigure(SharpDX.Direct2D1.FigureEnd.Open);
      geoSink.Close();
 
      RenderTarget.FillGeometry(polyGeo, areaDeviceBrush.BrushDX);

      polyGeo.Dispose();
  }​

Hello TradeForge,

Thanks for your post.

How exactly are the Vector2 objects being defined in the script?

How are you defining the brush used in the geometry? Are you calling something like the code below?

SharpDX.Direct2D1.SolidColorBrush customDXBrush = new SharpDX.Direct2D1.SolidColorBrush(RenderTarget, SharpDX.Color.DodgerBlue);

When calling geoSink.EndFigure() I see you are calling FigureEnd.Open. If you change FigureEnd.Open to FigureEnd.Closed, does the behavior persist?

On the help guide documentation below you could review "SharpDX Lines and Shapes" > "Geometry" sample code for an example of using PathGeometry, GeometrySink, and FillGeometry() to see how these are used:

You could also view the Ichimoku Cloud indicator from the NinjaTrader Ecosystem User App Share which also demonstrates using SharpDX to fill an area between points.

Brandon, thank you for your reply, the exemple provided with the indicator works perfectly after a few adaptations
