Constructor & Destructor Documentation

Arc2D()

Arc2D	(	double	x,
		double	y,
		double	radius,
		double	angle1,
		double	angle2
	)

Constructor.

Parameters

[in]	x	Center X coordinate.
[in]	y	Center Y coordinate.
[in]	radius	Radius.
[in]	angle1	Angle 1.
[in]	angle2	Angle 2.

Values of angles must be from -M_PI to M_PI (as returned by atan2()).
