[vtkusers] How do i port an image from ITK to VTK

[Omer Ishaq]

Hi

You need to use the following two classes from ITK and VTK.

1. itkVTKImageExport
2. vtkImageImport

Use itkVTKImageExport class at the end of your ITK pipeline and use the
vtkImageImport class at the start of your VTK pipeline. The connection
between these two classes will be created by calling the function
ConnectVTKToITK. The function is given below.

void ConnectVTKToITK(ExportType* in, ImportType* out)
{

out->SetUpdateInformationCallback(in->GetUpdateInformationCallback());
        out->SetPipelineModifiedCallback(in->GetPipelineModifiedCallback());
       out->SetWholeExtentCallback(in->GetWholeExtentCallback());
       out->SetSpacingCallback(in->GetSpacingCallback());
       out->SetOriginCallback(in->GetOriginCallback());
       out->SetScalarTypeCallback(in->GetScalarTypeCallback());

out->SetNumberOfComponentsCallback(in->GetNumberOfComponentsCallback());

out->SetPropagateUpdateExtentCallback(in->GetPropagateUpdateExtentCallback());
       out->SetUpdateDataCallback(in->GetUpdateDataCallback());
       out->SetDataExtentCallback(in->GetDataExtentCallback());
       out->SetBufferPointerCallback(in->GetBufferPointerCallback());
       out->SetCallbackUserData(in->GetCallbackUserData());
}

where ExportType is of type itkVTKImageExport and
ImportType is of type vtkvtkImageImport

regards
Omer
