draw_closed_curve() [3/4]

void xtd::drawing::graphics::draw_closed_curve	(	const pen &	pen,
		const std::vector< xtd::drawing::point > &	points,
		float	tension
	)

Draws a closed cardinal spline defined by an array of xtd::drawing::point structures using a specified tension.

Parameters

pen	xtd::drawing::pen that determines the color, width, and style of the curve.
points	Array of xtd::drawing::point structures that define the spline.
tension	alue greater than or equal to 0.0F that specifies the tension of the curve.

Remarks

This method draws a closed cardinal spline that passes through each point in the array. If the last point does not match the first point, an additional curve segment is added from the last point to the first point to close it.

The array of points must contain at least four xtd::drawing::point structures.

The tension parameter determines the shape of the spline. If the value of the tension parameter is 0.0F, this method draws straight line segments to connect the points. Usually, the tension parameter is less than or equal to 1.0F. Values over 1.0F produce unusual results.
