Description

Draws a n-gon.
A n-gon is a polygon with "n" number of sides. The minimum number of sides is three.
A n-gon is a closed path that can be filled, stroked or both. It is also possible to draw a n-gon invisible to apply the filling rules nonzero winding number or even-odd. The filling rules are described at DynaPDF.ClipPath. The parameter FillMode is ignored if the circle is drawn inside a clipping path. The fill modes are described at DynaPDF.ClosePath.

If the function succeeds the return value is OK, otherwise an error.
