[vtkusers] how to generate a vtkOutlineFilter from vtkImageData

[kdsfinger at gmail.com]

hi, all

I am trying to use the vtkImagePlaneWidget to show the image which was
read in itk and imported by using itkImageToVTKImageFilter.
itkImageToVTKImageFilter will export the data of vtkImageData. My
question is: with the vtkImageData in hand, how may I import it to a
vtkOutlineFilter?

Here is the part of the codes from the test of ImagePlaneWidget in vtk:

vtkVolume16Reader* v16 =  vtkVolume16Reader::New();
    v16->SetDataDimensions( 64, 64);
    v16->SetDataByteOrderToLittleEndian();
    v16->SetImageRange( 1, 93);
    v16->SetDataSpacing( 3.2, 3.2, 1.5);
    v16->SetFilePrefix( fname );
    v16->SetDataMask( 0x7fff);
    v16->Update();

  delete[] fname;

  vtkOutlineFilter* outline = vtkOutlineFilter::New();
    outline->SetInputConnection(v16->GetOutputPort());

  vtkPolyDataMapper* outlineMapper = vtkPolyDataMapper::New();
    outlineMapper->SetInputConnection(outline->GetOutputPort());

Thanks for help.
