center: Point2d,

Approximates an elliptic arc with a polyline.
The function ellipse2Poly computes the vertices of a polyline that approximates the specified
elliptic arc. It is used by #ellipse. If arcStart
is greater than arcEnd
, they are swapped.
Parameters
- center: Center of the arc.
- axes: Half of the size of the ellipse main axes. See #ellipse for details.
- angle: Rotation angle of the ellipse in degrees. See #ellipse for details.
- arcStart: Starting angle of the elliptic arc in degrees.
- arcEnd: Ending angle of the elliptic arc in degrees.
- delta: Angle between the subsequent polyline vertices. It defines the approximation accuracy.
- pts: Output vector of polyline vertices.
