Delphi function Area(const pts: TPath64): double;

C++ double Area(const Path64 &poly);

C#  public static double Area(Path64 poly);

This function returns the area of the supplied polygon. It's assumed that the path is closed and does not self-intersect. Depending on the path's winding orientation, this value may be positive or negative. If the winding is clockwise, then the area will be positive and conversely, if winding is counter-clockwise, then the area will be negative.
