[Insight-users] VTKImageImport

[Luis Ibanez]

Hi Juan,


The problem is that you are missing the keyword:

                              "typename"

This is a common mistake.

You need this keyword when you access a "Trait"
from a type that depends on one of the template
arguments of your class.



Instead of

   ImageImportType::Pointer movingpointer = ImageImportType::New();

You should do:

   typename  ImageImportType::Pointer movingpointer =
                             ImageImportType::New();


or even better, (because it is more readable),
you should do:

      typedef typename  ImageImportType::Pointer ImageImportPointer;
      ImageImportPointer movingpointer = ImageImportType::New();


  Regards,


         Luis
