Brush pattern in c# wpf (xaml - vector)

问题

I need to draw on canvas using a few brush patterns like "Paint" in Windows OS. I need "oil brush" and "pastel". As I understand, it's possible via VisualBrush.Visual (Canvas with vector paths).

In my app, I need to draw line on canvas with pattern (sample for user) and to draw, using this pattern, by mouse.

Can you help me with drawing, using brush pattern (step-by-step) in xaml and|or programmatically? It can be vector in xaml or image file using.

Now, I draw in xaml, using Brush pattern, but this is not oil brush (like in default paint app):
