[Insight-users] base classes not declared when defining a new class

[Bill Lorensen]

Matt,

1) You are missing a } to close the namespace in itkHammingWindowImageFilter.txx
2) You should #include <string> in the main program
3) When you reference stl string use std::string.
4) In itkHammingWIndowImageFIlter.txx, this->m_Window is not a pointer so the
this->m_Window->SetSize(window_size) should be
this->m_Window.SetSize(window_size) .

Bill
