[vtkusers] vtkImageData not aligned on X,Y,Z axes

[Jean-Michel Rouet]

Hi all,

I have an image that come from a MRI scanner. In the dicom file, the axis 
orientation with respect to the patient coordinate world are specified.
When I read this image with vtk (going through a raw data image and a 
vtkImageImport), I'm able to specify the extent and the origin but not the 
orientation.
Therefore, when I display this image (using vtkImagePlaneWidget) the image 
is not displayed with the correct orientation.
I tried to find out a way to transform the vtkImagePlaneWidget but to no 
avail.

So is there a way to rotate a vtkImageData somehow ?
Any other advice is welcome too...
