AW: [vtkusers] converting between itk and vtk

[Erbacher, Markus]

I have written a two function to connect pipes from itk and vtk. Perhaps it helps. It works fine for me.

template <typename ITK_Exporter, typename VTK_Importer>
static void ConnectPipelines(ITK_Exporter Exporter, VTK_Importer* Importer)
{
Importer->SetUpdateInformationCallback(Exporter->GetUpdateInformationCallback());
Importer->SetPipelineModifiedCallback(Exporter->GetPipelineModifiedCallback());
Importer->SetWholeExtentCallback(Exporter->GetWholeExtentCallback());
Importer->SetSpacingCallback(Exporter->GetSpacingCallback());
Importer->SetOriginCallback(Exporter->GetOriginCallback());
Importer->SetScalarTypeCallback(Exporter->GetScalarTypeCallback());
Importer->SetNumberOfComponentsCallback(Exporter->GetNumberOfComponentsCallback());
Importer->SetPropagateUpdateExtentCallback(Exporter->GetPropagateUpdateExtentCallback());
Importer->SetUpdateDataCallback(Exporter->GetUpdateDataCallback());
Importer->SetDataExtentCallback(Exporter->GetDataExtentCallback());
Importer->SetBufferPointerCallback(Exporter->GetBufferPointerCallback());
Importer->SetCallbackUserData(Exporter->GetCallbackUserData());
}

template <typename VTK_Exporter, typename ITK_Importer>
static void ConnectPipelines(VTK_Exporter* Exporter, ITK_Importer Importer)
{
Importer->SetUpdateInformationCallback(Exporter->GetUpdateInformationCallback());
Importer->SetPipelineModifiedCallback(Exporter->GetPipelineModifiedCallback());
Importer->SetWholeExtentCallback(Exporter->GetWholeExtentCallback());
Importer->SetSpacingCallback(Exporter->GetSpacingCallback());
Importer->SetOriginCallback(Exporter->GetOriginCallback());
Importer->SetScalarTypeCallback(Exporter->GetScalarTypeCallback());
Importer->SetNumberOfComponentsCallback(Exporter->GetNumberOfComponentsCallback());
Importer->SetPropagateUpdateExtentCallback(Exporter->GetPropagateUpdateExtentCallback());
Importer->SetUpdateDataCallback(Exporter->GetUpdateDataCallback());
Importer->SetDataExtentCallback(Exporter->GetDataExtentCallback());
Importer->SetBufferPointerCallback(Exporter->GetBufferPointerCallback());
Importer->SetCallbackUserData(Exporter->GetCallbackUserData());
}

Do you want this to happen in the pipeline without saving to files and
reloading? 

Yes.  Currently I have a version working that saves to files and reloads, but I would prefer to eliminate the extra I/O overhead.  I'm using itk::VTKImageImport and vtk::vtkImageExport to connect the pipelines.  Connecting the pipelines seems to work at first, but when I run any filters on the new itk image, I get an access violation in itkImageConstIterator::Get().
