[Insight-users] Public declaration of vtk and itk objects in MFC-applications

[Luis Ibanez]

It probably should just be:

         FixedImageType::ConstPointer ImageFix;

(without the "typedef"),

Since "ImageFix" is used later in the application
as a variable, not as a type. Like in:

        ImageFix = reader->GetOutput();


   Regards,


       Luis
