Standard_Boolean	Perform ()
	Builds and analyzes free bounds of the shape. First calls ShapeAnalysis_FreeBounds for building free bounds. Then on each free bound computes its properties:
Standard_Boolean	IsLoaded () const
	Returns True if shape is loaded
TopoDS_Shape	Shape () const
	Returns shape
Standard_Real	Tolerance () const
	Returns tolerance
Standard_Integer	NbFreeBounds () const
	Returns number of free bounds
Standard_Integer	NbClosedFreeBounds () const
	Returns number of closed free bounds
Standard_Integer	NbOpenFreeBounds () const
	Returns number of open free bounds
Handle_ShapeAnalysis_HSequenceOfFreeBounds	ClosedFreeBounds () const
	Returns all closed free bounds
Handle_ShapeAnalysis_HSequenceOfFreeBounds	OpenFreeBounds () const
	Returns all open free bounds
Handle_ShapeAnalysis_FreeBoundData	ClosedFreeBound (const Standard_Integer index) const
	Returns properties of closed free bound specified by its rank number
Handle_ShapeAnalysis_FreeBoundData	OpenFreeBound (const Standard_Integer index) const
	Returns properties of open free bound specified by its rank number

Detailed Description

• calculates area of the contour,
  
• calculates perimeter of the contour,
  
• calculates ratio of average length to average width of the
  contour,
  
• estimates average width of contour,
  
• finds the notches (narrow 'V'-like sub-contour) on the
  contour.
