So... I suggest to get a try with TransformData filter. Please note that it depends on your VTK file type, this filter does not work on any VTK file type. Works fine on UG (.vtu) data, AFAIK. http://fredantispam.free.fr/snapshot1.png : not scaled http://fredantispam.free.fr/snapshot2.png: scaled along Oz axis x 10. HTH.
