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.
