[vtkusers] Problem with vtkDataArray::SetVoidArray

[n.sunilkumar]

hi vtkusers,

The problem....

I am passing a big array into vtk using vtkDataArray::SetVoidArray method from cpp and then utilizing this in vtkImageData which will be passed to filter say Median.

I am able make a vtkImageData in the above mentioned way but unable to see any effect of fitler on the data. It remains unchanged when filter::Update is called.

In order to realise that the data is imported properly i tried making a local copy of the 
VtkImageData by using vtkImageData::CopyAndCastFrom method....This is generating an error which sayas GetScalarPointer xxxxx not in memory....

any help would be appreciated

with regards
Sunil.
