[vtkusers] vtkImageViewer2 border

[Steven Hou]

Hi all, I am trying to display a 2D image with vtkImageViewer2 which is
placed within a wxWidget object. I can get the image to display properly
except I get this black border around my image (see attached image). I am
wondering how do I make the image I am trying to view fit completely inside
my widget (with no black border surrounding the image)?

Code snippet I am using:

wxVTKRenderWindowInteractor *m_pVTKWindow = new
wxVTKRenderWindowInteractor(notebook, MY_VTK_WINDOW);
vtkImageData *image = vtkImageData::New();
image = ...
vtkImageViewer2 *viewer = vtkImageViewer2::New();

viewer->SetColorWindow(2400);
viewer->SetColorLevel(1200);
viewer->SetInput(image);
viewer->SetupInteractor (NULL);
m_pVTKWindow->SetRenderWindow(viewer->GetRenderWindow());
viewer->GetRenderer()->ResetCamera();

Thanks
