[Rtk-users] how to transform itk.CudaImage[itk.F, 3] to itk.Image[itk.F, 3] in python?

[Simon Rit]

Hi,
You can find here
<https://github.com/RTKConsortium/RTK/blob/master/examples/FirstReconstruction/FirstCudaReconstruction.py#L70-L76>
how to convert an itk.Image to an itk.CudaImage. An itk.CudaImage is an
itk.Image (by inheritance) so you should not need to convert it, just use
it as if it were an itk.Image, as illustrated in the same example here
<https://github.com/RTKConsortium/RTK/blob/master/examples/FirstReconstruction/FirstCudaReconstruction.py#L91>.
Or have I missed something?
Simon
