[ITK-users] Filter working on exporting, not in view (VTK)

[Marcos]

Hi,

I have an itk::Image, and set it as input of a IntensityWindowingImageFilter

I change the values of window level and, if I export, I see changes. But I
don't see these changes on VTK. After doing a change, I update the
QVTKWidget or the vtkImageViewer2, but I see the same image. I'm not sure
if the ImageToVTKImageFilter is the problem.

My pipeline is:
itk::Image -> IntensityWindowingImageFilter -> vtkImageFlip
->vtkImageViewer2 -> QVTKWidget

Exporting is working:
itk::Image -> IntensityWindowImageFilter -> ImageFileWriter

Greetings.
