[vtkusers] Re: Modify scalar values

[Moti Freiman]

Hello!
As far as I know, you can't just copy vtk pointers. instead of it you 
should use:

<>vtkDataArray *scalarArrayDestination = vtkDataArray::New()
and on of the beloew:
scalarArrayDestination ->DeepCopy 
(LabeledImage->GetPointData()->GetScalars());
scalarArrayDestination->ShallowCopy 
(LabeledImage->GetPointData()->GetScalars());
the difference between ShallowCopy, and DeepCopy, is that shallow copy 
just create another reference to the same object.
and deepcopy, make another new object.
for more details you can take a look at the vtk documentation.
be aware that vtkDataArray is abstract class, you should use 
vtkFloatArray, or something like this.
hope it helps.
