[vtkusers] Error with extent

[Sergio Andres]

Hi all,

I got an error from vtk : "Update extent does not lie within whole 
extent", but I don't know how to fix it.

First, I build a new 3D vtkImageData, and then I use vtkImageReslice to 
get a new 2D slice.
It is this slice which causes the error, since it is the input to a 
vtkImageActor.
Before rendering, the image extents seems to have the right values, but 
after rendering
this values are different and the error comes up (the renderer modifies 
these values...??)

Has anyone a solution?

Thanks!
Sergio
