<DIV><FONT face=Arial size=2>I notice that when I use a vtkImageToImageFilter,
it will modify the input image to the filter if I call Update( ) on the
filter! That happened to me when I used vtkImageChangeInformation() or
vtkExtractVOI( ). And I tried replacing a call to Update( ) by
calling Modified( ) on the filter. This way the input image isn't
modified, but then the output image isn't what I want either.

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>How can I ask the filter to create a new image for
me without my input imgae being modified?</FONT></DIV>
