Method IMVGaugeCalculations::CalcAngle2L

Declaration: Function CalcAngle2L(Point1 As Long, Point2 As Long, Point3 As Long, Point4 As Long) As Double

Calculate the angle between two lines.

Parameter:

	Point1	Index of the first point  from the first line.
	Point2	Index of the second point from the first line.
	Point3	Index of the first point  from the second line.
	Point4	Index of the second point from the second line.

C Prototype:

HRESULT CalcAngle2L(LONG Point1, LONG Point2, LONG Point3, LONG Point4, DOUBLE* value);
