[vtkusers] Shrinking volume data makes VTK to crash

[Cristian Luciano]

Hi everyone,

Have you tried to shrink a volume data (using vtkShrinkFilter)? 
The volume data comes from the visible woman.
VTK crashes when trying to shrink data. And so does Paraview too!

The C++ code is as follows:

//****************************************************************
 vtkImageReader *BodyVolume = vtkImageReader::New();
  BodyVolume->SetFilePrefix (fileName);
  BodyVolume->SetFilePattern ("%s");
  BodyVolume->SetDataScalarType(4);
  BodyVolume->SetDataByteOrder(0);
  BodyVolume->SetFileDimensionality(3);
  BodyVolume->SetDataOrigin(0, 0, 0); 
  BodyVolume->SetDataSpacing(1, 1, 1); 
  BodyVolume->SetDataExtent(0, 255, 0, 255, 0, 577); 
  BodyVolume->SetNumberOfScalarComponents (1);

 vtkShrinkFilter *shrink = vtkShrinkFilter::New();
  shrink->SetInput((vtkDataSet *)BodyVolume ->GetOutput());
  shrink->SetShrinkFactor(0.5);
  shrink->Update();

//****************************************************************

Any ideas? Thanks in advance.

Cristian
