[Insight-users] problem in using itkLabelOverlayImageFilter in 3D

[john smith]

Hello to all,

I had used the itkLabelOverlayImageFilter  in 2D and I didn;t have any
problem. No I am trying to use tis filter in 3D. I have written exactly the
same code but for 3D, and I get this error which I don't know what exactly
means.

the error is the following:
error C2440: 'initializing' : cannot convert from
'itk::Concept::Detail::UniqueType_unsigned_int<__formal>' to
'itk::Concept::Detail::UniqueType_unsigned_int<__formal>'

I hope someone could help me.
Thanks in advance

 typedef itk::Image<unsigned char, 3>  ImageType;
   ImageType::Pointer image1 = ImageType::New();
   ImageType::Pointer image_label = ImageType::New();

   typedef   unsigned char           InternalPixelType_add;
   const     unsigned int    Dimension = 3;
   typedef itk::Image< InternalPixelType_add, Dimension >

   typedef  itk::ImageFileReader< InternalImageType_add > ReaderType_add;

    ReaderType_add::Pointer reader1 = ReaderType_add::New();
    reader1->SetFileName( fileName.toStdString()  );

    ReaderType_add::Pointer reader2 = ReaderType_add::New();
    reader2->SetFileName( "result.hdr"  );
    reader2->Update();
    image_label = reader2->GetOutput();

  typedef itk::LabelOverlayImageFilter<ImageType, ImageType, RGBImageType>

  labelOverlayImageFilter->SetLabelImage(image_label);
 // labelOverlayImageFilter->SetOpacity(.5);
  labelOverlayImageFilter->SetOpacity(1.0);
  labelOverlayImageFilter->ResetColors(); // reset color map
  labelOverlayImageFilter->AddColor(0, 0, 255); // fill color map with blue
  labelOverlayImageFilter->SetBackgroundValue(0); // don't overlay the
background, i.e., label 0
  labelOverlayImageFilter->Update();

  typedef  itk::ImageFileWriter< RGBImageType  > WriterType;
  WriterType::Pointer writer = WriterType::New();
  writer->SetFileName("output.hdr");
  writer->SetInput(labelOverlayImageFilter->GetOutput());
  writer->Update();
