[vtkusers] problem with vtkdecimatPro::GetNumberOfPolys()

[sonia specher]

Good morning,
after having done the decimation of a vtkDecimatePro
object and rendered it on a window, i want to know the
number of the polygons which composed the new 3D
object. So i applie the GetNumberOfPolys() method on
the vtkDecimatePro object, but when i print this
number it gives the same number of polygons that there
was on my 3D object before decimation.
Have you any idea on why i don't have the real number
of polygons ?
Have a nice day.
Sonia
