[vtkusers] How to clip vtkImageData

[Chou Yi-Yu]

Dear vtk users,

I have a 3D image (image) with vtkImageData format.
I want to clip it by the following pipeline :
.....................................................................................................

plane = vtkPlane()
plane.SetOrigin(0.25,0,0)
plane.SetNormal(0,0,1)
		
clipper = vtkClipPolyData()
clipper.SetInput(image)
clipper.SetClipFunction(plane)
clipper.GenerateClippedOutputOn()
clipper.SetValue(0.5)
		
clipMapper = vtkPolyDataMapper()
clipMapper.SetInput(clipper.GetOutput())
clipActor = vtkActor()
clipActor.SetMapper(clipMapper)
.............................................................................................................................

However, clipper.SetInput() requires a vtkPolyData not vtkImageData.
How should I do ???????
Thanks in advance !!!

YY
