scale_about_centre¶

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.

Parameters:	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.
Returns:	transform (`Homogeneous`) – A homogeneous transform that implements the scaling.
