Hello,
I'm trying to draw in a WPF Canvas, some polylines with border.
For that purpose i've used a StreamGeometry, a PathGeometry and a "Path".
This is my code:

C#

StreamGeometry geom = new StreamGeometry();

//this method fills the StreamGeometry with a polyline
DrawLines(geom, polyObj);

PathGeometry pathGeometry = geom.GetWidenedPathGeometry(new Pen(Brushes.Black, 10));
GeometryDrawing geoDrawing = new GeometryDrawing();
geoDrawing.Geometry = pathGeometry;

Path myPath = new Path();

myPath.Fill = Brushes.LightGreen;
myPath.Stroke = Brushes.Black;
myPath.StrokeThickness = 0.4;
myPath.Name = "tratta"+tratta.id;
myPath.Data = pathGeometry;
myPath.StrokeLineJoin = System.Windows.Media.PenLineJoin.Round;

canvas.Children.Add(myPath);

The code is working, but when a polyline has more than two vertex, i obtain this graphic problems on a junction:

Image - Junction

How can i resolve this problems? Thanks in advance

You could use DrawingVisuals, but that seems to be a bit over the top for this. What happens if you try different joins?

Ehm, I don't see how that would solve the issue?
