const XY& Geom::Pnt2d::coord ( ) const

For this point, returns its two coordinates as a number pair.

◆ coord() [2/3]

double Geom::Pnt2d::coord ( const int Index ) const

Returns the coordinate of range Index :
Index = 1 => x is returned
Index = 2 => y is returned
Raises OutOfRange if Index != {1, 2}.

◆ coord() [3/3]

void Geom::Pnt2d::coord	(	double &	Xp,

double Geom::Pnt2d::distance ( const Pnt2d & Other ) const

Computes the distance between two points.

◆ isEqual()

bool Geom::Pnt2d::isEqual	(	const Pnt2d &	Other,
		const double	LinearTolerance
	)		const

Comparison
Returns True if the distance between the two
points is lower or equal to LinearTolerance.

◆ mirror() [1/2]

void Geom::Pnt2d::mirror ( const Pnt2d & P )

Performs the symmetrical transformation of a point
with respect to the point P which is the center of
