[vtkusers] Outline of a result from a vtkimagereslicemapper

[Doug Hoppes]

Hi all,

                I've gotten the image reslice mapper working beautifully for my image volume.  However, I'm trying to get the outline filter to work so that I can show a bound region around my image slice.  All I'm showing is a small square in the upper left corner:

The code that I'm using is:

First Function
---------------------------
      // Create the plane that will hold the slice results
      m_pSlicePlane = vtkSmartPointer<vtkPlane>::New();

      // extract a slice from the volume
      m_pSliceMapper = vtkSmartPointer<vtkImageResliceMapper>::New();
      m_pSliceMapper->SetInputData(GetImageDefinition()->GetImage()->GetImageData());
      m_pSliceMapper->SetSlicePlane(m_pSlicePlane);

      // Set it up so that the slice is not affected by the current lighting situation
      vtkSmartPointer<vtkImageProperty> m_sliceProperty = vtkSmartPointer<vtkImageProperty>::New();
      m_sliceProperty->SetAmbient(1.0);
      m_sliceProperty->SetDiffuse(0.0);
      m_sliceProperty->SetOpacity(1.0);
      m_sliceProperty->SetInterpolationTypeToLinear();

      // Create the mapper to display the slice
      m_pSliceActor = vtkSmartPointer<vtkImageSlice>::New();
      m_pSliceActor->SetMapper(m_pSliceMapper);
      m_pSliceActor->SetProperty(m_sliceProperty);

      // Add the slice to the scene
      m_pSceneManager->AddActor(m_pSliceActor);
---------------------------


Another Function
---------------------------
      // setup the outline actor
      vtkSmartPointer<vtkOutlineFilter> pOutlineFilter = vtkSmartPointer<vtkOutlineFilter>::New();
      pOutlineFilter->SetInputConnection(m_pSliceMapper->GetOutputPort());

      vtkSmartPointer<vtkPolyDataMapper> pOutlineMapper = vtkSmartPointer<vtkPolyDataMapper>::New();
      pOutlineMapper->SetInputConnection(pOutlineFilter->GetOutputPort());

      // Set the color of the slice
      double rgbColor[3];
      SolidsColor::ToVTKRGB(rgbColor, GetImageDefinition()->GetColor());
      m_pOutlineActor->GetProperty()->SetColor(rgbColor[0], rgbColor[1], rgbColor[2]);
      m_pOutlineActor->SetMapper(pOutlineMapper);
---------------------------
