16.4.1 Pen and RawPen Objects

Pen and RawPen objects have all the global functions described above, except for demo() as methods, which manipulate the given pen.

The only method which is more powerful as a method is degrees().

degrees( [fullcircle]): fullcircle is by default 360. This can cause the pen to have any angular units whatever: give fullcircle 2* $\pi$ for radians, or 400 for gradians.
