Examples
This examples make use of GraphicsPath and Graphics classes to create and manipulate figures on an Image surface. Example creates a new Image (of type Tiff), clears the surface and draws paths with the help of GraphicsPath class. At the end draw_path method exposed by Graphics class is called to render the paths on surface.

# Draw path with Pen object of color Black
