PasteImageFilter and RegionOfInterestImageFilter are not currently wrapped for itk.VectorImage to/from itk.Image[itk.Vector] types, we can add that wrapping if one of these would be the best route.
I noticed that itkImageToImageFilterA.wrap contains a basis for VectorImage <-> Vector transformation, I’m not sure if there is a class already inheriting from this that could provide conversion.
