Wpf line with variable thickness

Is there any way to create lines (Xaml), with different thickness, like this:

I have one solution: closed path with开发者_如何学Python fill. Is there another one?

You could try it with an ink object, i.e. Stroke with a few StylusPoints that have a pressure. But whether pressure will be rendered as varying thickness might depend on other things as well. I guess, the best way is still the path in this case.

The only other way I see would be to create a custom control that would do it. Otherwise, I believe a path is the best way.

You could draw multiple lines and connect them. Maybe you could apply some kind of transformation matrix, but I also have no clue how exactly this could work.

this is pretty much what Path is for
