===============


.. class:: PointsObjectMixin

   A mixin class that provides some methods suitable for use
   with objects that have a set of (x, y) coordinate pairs.

   .. method:: CalcBoundingBox(self)

      Calculate the bounding box.


   .. method:: Move(self, Delta)

      Moves the object by delta, where delta is a (dx, dy) pair.
      
      :param `Delta`: is a (dx, dy) pair ideally a `NumPy <http://www.numpy.org/>`_
       array of shape (2, )


   .. method:: SetPoints(self, Points, copy=True)

      Sets the coordinates of the points of the object to Points (NX2 array).
      
      :param `Points`: takes a 2-tuple, or a (2,)
       `NumPy <http://www.numpy.org/>`_ array of point coordinates
      :param boolean `copy`: By default, a copy is made, if copy is set to
       ``False``, a reference is used, if Points is a NumPy array of Floats.
       This allows you to change some or all of the points without making
       any copies.
      
      For example::
      
          Points = Object.Points
          # shifts the points 5 in the x dir, and 10 in the y dir.
          Points += (5, 10)
          # Sets the points to the same array as it was
          Object.SetPoints(Points, False)
