Description

This function draws a circle.
The draw direction can be changed with the function DynaPDF.SetDrawDirection.
A circle is a closed path that can be filled, stroked or both. It is also possible to draw a circle invisible to apply the filling rules nonzero winding number or even-odd. The filling rules are described under DynaPDF.ClipPath. The parameter FillMode is ignored if the circle is drawn inside a clipping path. The fill modes are described under DynaPDF.ClosePath.
