[ITK-users] CenteredTransformInitializer Python Wrapping

[Bradley Lowekamp]

Hello,

I would recommend using the "MatrixOffsetTransformBase" class for the template parameters. This enables the class to be used with any derived type.

This is they way I did it in SimpleITK [1].

There seems to be a problem however, as the CenteredTransformInitializer in Python only seems to work with the rigid transforms now. The wrapping file looks like this:
