Hi,
Over a month ago I set out to use ITK through python by wrapping custom 
subclasses of ITK. I wrote most of the relevant ITK c++ code and 
constructed vtk-python based visualization classes. During this time, I 
posted several messages on this list asking for help in creating python 
wrappers for custom subclasses of ITK. I was assured that this would 
not be too hard, but I have yet to manage to do this. Also, no one 
seems to have any working examples of wrapping custom classes. I have 
managed to create wrappers for templated functions which access ITK 
data structures as is done in ConnectVTKITK. I have also managed to 
create wrappers for classes which do not subclass ITK classes. I have 
not managed to create a wrapper for even the simplest ITK subclass:

template<typename TPixel>
class Image2D : public itk::Image< TPixel, 2 >
{
  public:
   typedef Image2D                         Self;
   typedef itk::Image                      Superclass;
   typedef itk::SmartPointer<Self>         Pointer;
   typedef itk::SmartPointer<const Self>   ConstPointer;
   itkNewMacro( Self );
   itkTypeMacro( Image2D, Image );
}

I tried using the following cable config file:

%module TestPython
%{
#include "itkImage.h"
#include "Test.h"
%}
%include "Test.h"
%template(classNameUS2) className<itk::Image<short unsigned int, 2> >;

I can't seem to get this to be processed. Is there anyone out there who 
could help me. I have invested considerable time in understanding ITK 
and would hate to have to start looking for a new framework.

Any help would be greatly appreciated.

Carlos
