## Module: `algorithms.registration.transform`

Inheritance diagram for `nipy.algorithms.registration.transform`:

Generic transform class

This implementation specifies an API. We’ve done our best to avoid checking instances, so any class implementing this API should be valid in the places (like registration routines) that use transforms. If that isn’t true, it’s a bug.

## `Transform`

class nipy.algorithms.registration.transform.Transform(func)

  Bases: `object`

  A default transformation class

  This class specifies the tiny API. That is, the class should implement:

  - obj.param - the transformation exposed as a set of parameters. Changing param should change the transformation

  - obj.apply(pts) - accepts (N,3) array-like of points in 3 dimensions, returns an (N, 3) array of transformed points

  - obj.compose(xform) - accepts another object implementing `apply`, and returns a new transformation object, where the resulting transformation is the composition of the `obj` transform onto the `xform` transform.
