Hi,
are these 2D images?
The itk::Image template class expects two parameters, the pixel type and
the dimension. For the dimension there is a default value that is 2. That's
why your code does not cause compile error.
However, you must cast the mitk::Image into exactly the same kind of
itk::Image. If you have a 3D mitk::Image, you cannot cast it into a 2D itk
image. Even the pixel types must be the same.
In your code:
itk::Image < ImageType > ::Pointer itkImage_1;
The ImageType name is rather misleading, since a primitive type should be
there, typically.
Best,
Miklos
