VS:ClipPolygon

.VectorScript|VectorScript ..VS:Function Reference|Function Reference ..VS:Function_Reference_Appendix|Appendix

Description

Same as IntersectSurface, but improves performance by first checking to see if hClipper is within the bounding box of hPolygon before calling IntersectSurface.

Not sure what dFuzz does.

Returns the handle of the result. Beware: if the clipping operation should have returned more than one polygon, only the first polygon will be returned.

FUNCTION ClipPolygon(
           hPolygon   :HANDLE;
           hClipper   :HANDLE;
           dFuzz      :REAL) :HANDLE;

def vs.ClipPolygon(hPolygon, hClipper, dFuzz):
    return HANDLE

Parameters

hPolygon		HANDLE
hClipper		HANDLE
dFuzz		REAL

Remarks

I don't think that this works from inside Plug-in objects.

Example

PROCEDURE Example;
VAR
   h1, h2, h3 :HANDLE;
BEGIN
   CallTool(-204); h1 := FSActLayer;
   CallTool(-204); h2 := FSActLayer;
   h3 := ClipPolygon(h1, h2, 1);
END;
Run(Example);
