intersecting polygons [message #29394]

Hi,

Does anybody know of, or have a routine that could take polygonal
areas and find the common area between them? Consider the first
polygon defined by the set of points x1,y1 where x1 and y1 are arrays.
The second polygon is defined by the set of points x2 and y2. What I
am looking for is the points where the lines given by x1,y1 and x2,y2
intersect. Owing to limited time I am wondering if anybody has written
such a routine, that would return a polygon describing the area common
to both polygons.

I'd be most grateful for any responses!

Jon Pearce.
