int Length

(

const IPoint2 &

v

)

[inline]

Remarks:

Returns the length of the IPoint2, ie:

sqrt(v.x*v.x+v.y*v.y);

Definition at line 117 of file ipoint2.h.

                                    {   
    return (int)sqrt((double)(v.x*v.x+v.y*v.y));
    }

GEOMEXPORT IPoint2 Normalize

(

const IPoint2 &

)

Remarks:

Returns a unit vector. This is an IPoint2 with each component divided by the point Length().

IPoint2 operator*	(	int	f,
		const IPoint2 &	a
	)		[inline]

Remarks:

Returns an IPoint2 multiplied by a scalar.

Definition at line 157 of file ipoint2.h.

                                                  {
    return(IPoint2(a.x*f, a.y*f));
    }

IPoint2 operator*	(	const IPoint2 &	a,
		int	f
	)		[inline]

Remarks:

Returns an IPoint2 multiplied by a scalar.

Definition at line 161 of file ipoint2.h.

                                                  {
    return(IPoint2(a.x*f, a.y*f));
    }

IPoint2 operator/	(	const IPoint2 &	a,
		int	f
	)		[inline]

Remarks:

Returns an IPoint2 whose x and y members are divided by a scalar.

Definition at line 165 of file ipoint2.h.

                                                  {
    return(IPoint2(a.x/f, a.y/f));
    }
