<DIV><FONT face=Arial size=2>Hi!</FONT></DIV>
<DIV><FONT face=Arial size=2> I'm starting to work with
integration between ITK and VTK, and I wrote a basic program, as
follows:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>

"itkRawImageIO.h"<BR>#include "itkVTKImageExport.h"<BR>#include

<DIV>which just reads a raw image with ITK and passes it to VTK for
visualisation. I get an unresolved external symbol error during compilation (VS
.NET 2005) concerning the callback fuctions in VTKImageExportBase:</DIV>

<DIV> Do I have to create those functions? From what I read in
the docs, I think that these are passed to VTKImageImport, that sets them as its
callbacks. Also, it seemed like an "include" error, but ITK's
VTKImageExport header includes the VTKImageExportBase header file. </DIV>

<DIV>Am I missing some libraries?</DIV>
