[vtkusers] Importing Numarray object with vtkImageImport

[Bruno]

Hi,

I'm trying to import a Numarray object passing it direct do
vtkImageImport
it is like:

import numarray
a = numarray.array([...], 'type')
i = vtkImageImport()
...
i.CopyImportVoidPointer(a, size)

TypeError: argument 1 must be string or read-only buffer, not NumArray

I knowm that's possible to do it with Numeric python(and it was
mentioned
in this list as the 'Numeric trick' some months ago), but when I try
with Numarray, that what happens. But if I do:

i.CopyImportVoidPointer(a._data, size)

it works!!! How can I do to direct pass the numarray object, whithout
messing whith the protected methods (a._data)??? Do I have to change the

numarray implementation or the vtkImageImport.cxx class??

thank's...
