[Insight-users] converting vtkImageData to itkImage using itk::VTKImageToImageFilter

[Prathamesh Kulkarni]

Hello ITK users,

I am have started to use ITK a few days ago!

I am having trouble with converting vtkImageData to itkImage. The previous
posts on the list did not help me. Following is my code for converting
vtkImage to itkImage:

>
>     typedef itk::Image<unsigned char, 2> ImageType;
>
>     typedef itk::VTKImageToImageFilter<ImageType> VTKToITKConnector;
>     VTKToITKConnector::Pointer VTK_to_ITK_filter =
> VTKToITKConnector::New();
>
>
>     VTK_to_ITK_filter->SetInput(vtkImageData); //vtkImageData is unsigned
> char and single channel
>     VTK_to_ITK_filter->Update();
>
>     ImageType::Pointer itk_image = VTK_to_ITK_filter->GetOutput(); //THIS
> LINE  GIVES THE ERROR SHOWN BELOW
>
>
>     //itk::SmartPointer<ImageType> itk_image =
> VTK_to_ITK_filter->GetOutput();
