[vtkusers] vtkPNMReader+vtkTransform --> Duplicate Actors

[Mohamed Sabry]

Hi Every One,

I am using vtk3.2 with VtkkQt to provide GUI. I first load from the program 
a stack of pgm files using vtkPNMReader, which is okay. Then from the GUI, i 
pass the angle to rotate the volume, but strangely, it mades another copy of 
the actor in the scene either by rotating the actor or using vtkTransform 
for the data itself, and whenever i enter a new angle, the actor keep 
duplicating. This does not happen if i use vtkPolyData points instead of 
images.
any suggestion how to solve the problem.
