In order to pad on the left, you must adjust the image Origin and<br>
Extent at the same time. This can be done with<br>
vtkImageChangeInformation, if you know the image spacing ahead of<br>
time:<br>
<br>
translator = vtkImageChangeInformartion();<br>
translator.ExtentTranslation(padx, pady, padz);<br>
translator.OriginTranslation(-padx*xspacing, -pady*yspacing, -padz*zspacing)<br>
<br>
pad = vtkImagePadFilter()<br>
pad.SetInputConnection(translator.GetOutputPort())<br>
etcetera.<br>
<br>
In all honesty, though, someone should add an option to<br>
vtkImagePadFilter so that it can shift the image and pad it at the<br>
same time.<br>
