At the beginning, I was hinting that you should probe with a
vtkImageData, which you could have written out as an image
(either as raw data, or as a png, etc).  But now that you have
the probed data as a polydata plane, you'll have to get the
scalars that are associated with the points that make up the
polydata.  GetPointData()->GetScalars() will return an array
that contains all the scalars.  See the VTK text for an in-depth
description of how data is stored in a VTK data set.
