[vtkusers] vtkImageReslice: what do I fill in for SetResliceAxesDirectionCosines.?

[Nico Vermaas]

Hi,

I try to get a slice from my vtkImageData cube, but I do not understand the documentation of SetResliceAxesDirectionCosines. 

Q1:
Say, my cube is: 0..100,0..100,0..100 and I want a slice that runs from 10..20,0..100,0.100. So a slice of 10 thick in the Y/Z plane. 
What must I then fill in in for SetResliceAxesDirectionCosines?

Q2: Why is vtkImageReslice better than vtkExtractVOI?

Greetings,

Nico
