add_closed_curve() [3/4]

void xtd::drawing::drawing_2d::graphics_path::add_closed_curve	(	const std::vector< xtd::drawing::point > &	points,
		float	tension
	)

Adds a closed curve to this path. A cardinal spline curve is used because the curve travels through each of the points in the array.

Parameters

points	An array of xtd::drawing::point_f structures that represents the points that define the curve.
tension	A value between from 0 through 1 that specifies the amount that the curve bends between points, with 0 being the smallest curve (sharpest corner) and 1 being the smoothest curve.

Remarks

The user must keep the original points if they are needed. The original points are converted to cubic Bézier control points internally, therefore there is no mechanism for returning the original points. If the first point and the last point in the points array are not the same point, the curve is closed by connecting these two points.
