[vtkusers] A method to get limit values

[anast.jm at pg.com]

Marcio,

vtkStructuredPointsReader I'm guessing produces a vtkStructuredPoints output
datatype. This is a subclass of vtkImageData which is a subclass of vtkData.
vtkData has a method GetScalarRange which will return two float values of the
min and max......john

Hi,

I am  using vtkStructuredPointsReader to capture a data point array to be
evaluated by its isosurfaces (by using vtkContourFilter).I  did not find any
method to extract the minimum and maximum values from the data  set.
Has someone a sugestion how to do it?

Regards, Marcio.
