		double &	phit
	)

Calculation of center for the Arc.

Parameters:

	begin_x	x start point of arc.
	begin_y	y start point of arc.
	middle_x	x middle point of arc.
	middle_y	y middle point of arc.
	end_x	x end point of arc.
	end_y	y end point of arc.
	radius	radius of the circle calculated
	center_x	x of the center calculated
	center_y	y of the center calculated
	beginrad	calculated starting angle in radians
	midrad	calculated middle angle in radians
	endrad	calculated end angle in radians
	phit	total calculated in radians (AntiClockwise positif, else negatif )

Returns:

true if the arc is indeed an Arc if a straight line return false.

double ClclDistSqrPntLine	(	const a2dPoint2D &	p,
		const a2dPoint2D &	p1,
		const a2dPoint2D &	p2
	)

Calculate the square distance between a point and a line.

This returns DBL_MAX if the point is beyond the edges

Definition at line 103 of file polyver.cpp.

bool InArc	(	double	angle,
		double	start,
		double	end,
		bool	clockwise
	)

is the angle within the arc segment taking into account drawing from start to end in clockwise or anti clocwise direction.
