transform_about_centre¶

menpo.transform.transform_about_centre(obj, transform)[source]¶

Return a Transform that implements transforming an object about its centre. The given object must be transformable and must implement a method to provide the object centre. More precisely, the object will be translated to the origin (according to it’s centre), transformed, and then translated back to it’s previous position.

Parameters

obj (Transformable) – A transformable object that has the centre method.
transform (ComposableTransform) – A composable transform.

Returns

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