lcIntersection

Searches intersection points of 2 graphic objects. The object types can be the following: Line, Construction line, Polyline, Rectangle, Circle, Arc, Ellipse.

int lcIntersection (
   HANDLE hEnt,
   HANDLE hEnt2,
   int Apparent
);

Parameters

hEnt
	Handle to first graphic object.
hEnt2
	Handle to second graphic object.
Apparent
	Allows to find intersection point outside of objects limits. Can be one of the following values: 0 - find intersection point only within objects geometry. 1 - treat first object (hEnt1) as infinite. 2 - treat second objects (hEnt2) as infinite. 3 - treat both objects as infinite.

Return Value

A number of intersection points.

Remarks

This function stores found intersection points in inner buffer. Retrieve points from the buffer by subsequent call of the lcInterGetPoint function.
