Hi all,

I want to specify a ConstantBoundaryCondition in a shaped iterator; my 
code looks like:

// appropriate headers

// types definitions
1  typedef unsigned char PixelType;
2  typedef itk::Image< PixelType, 2 >  ImageType;

3  typedef itk::ConstantBoundaryCondition< ImageType > 
MyBoundaryConditionType;
4  typedef itk::ConstShapedNeighborhoodIterator< ImageType ,
                                                MyBoundaryConditionType 
 > ShapedNeighborhoodIteratorType;

...
5  ShapedNeighborhoodIteratorType it=...;
6  const MyBoundaryConditionType *condition = NULL;
...
7 condition = it.GetBoundaryCondition();

===========
At this last line (7), the compiler outputs an error, and I dont know 
how to correct it, because I thought I had templated the 
neighborIteratorType with MyBoundaryCondition.

OuvertureDiagonale.cc: In function `int main(int, char**)':
OuvertureDiagonale.cc:213: error: cannot convert `const 
itk::ZeroFluxNeumannBoundaryCondition<main(int, char**)::ImageType>*' to 
`const main(int, char**)::MyBoundaryConditionType*' in assignment

Can anyone explain my problem?

thank you for your time.
Yann
