closed poly


Recommended Posts

It's impossible.

However, the "Closed" function can be made.

function Closed(hPoly: handle): boolean;




fPat:= GetFPat(hPoly);

SetFPat(hPoly, 0);

if HArea(hPoly) = 0 then

Closed:= false


Closed:= true;

SetFPat(hPoly, fPat);

end; {Closed}

In most cases, this is faster than the "IsPolyClosed" function.
