FUNCTIONellipse2Poly

RETURN TYPEvoid

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

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.

ellipse2Poly(center: Point, axes: Size, angle: number, arcStart: number, arcEnd: number, delta: number, pts: PointVector): void;

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 destination, filled by the native operation. Output vector of polyline vertices.
