Hi tuo zhang,

You can use the "SetTransform" method in vtkImageReader. Supply a 
vtkTransform as an argument.

Look here for the different transforms you may like to set up:
http://www.cs.utah.edu/classes/cs5630/vtk%204.4.2/vtkhtml/applications/segment/scripts/SliceOrder.tcl

If want a separate filter to do the transformation for you use 
vtkImagePermute.
