Hi Tuhin and Yang

Thanks for pointing this out.

Your are right the wrapping is missing for images
of pixel type = Vector<> and CovariantVector<>.

We will be adding those types in the following days.
They will be for types float/double and 2D/3D.

--

About the methods that may be missing in the wrapped
classes: This usually happens when the method is
provided by a superclass and that superclass is not
being wrapped.

Please let us know what methods you are not finding.
That will help us to find the superclass that must
be added to the wrapping.


   Thanks,


      Luis
