<P>&nbsp;</P>


<P>I have a problem with itkImage.</P>


<P>&nbsp;</P>


<P>I want to convert raw data to&nbsp;itkImageType.</P>


<P>&nbsp;</P>


<P>I've loaded .png file using ATL::CImage class(MFC 2003). </P>


<P>&nbsp;</P>


<P>and I want to convert this memory data to itkImageType.</P>


<P>&nbsp;</P>


<P>My code is follow:</P>


<P>&nbsp;</P>
