menpo.transform.scale_about_centre(obj, scale)[source]

Return a Homogeneous Transform that implements scaling an object about its centre. The given object must be transformable and must implement a method to provide the object centre.

  • obj (Transformable) – A transformable object that has the centre method.
  • scale (float or (n_dims,) ndarray) – The scale factor as defined in the Scale documentation.

transform (Homogeneous) – A homogeneous transform that implements the scaling.
