imaging pipeline qn..

[K.R.Subramanian]

I am using the imaging pipeline to perform some image processing, but
I dont use the viewer. I am having difficulty in forcing the output of
the imaging filters.. for instance I have a simple  sequence as

vtkImageData-->vtkImageClip--> (clipped scalars)

I am trying to get the imaging data (scalars) from the above pipeline. I
called
Update() on the vtkImageClip() and try to get at the scalars by using
the GetPointData() method, but the scalars are not there. I know
vtkImageClip
only sets the clipping extent, but how do I force it to execute so that
I
can retrieve the clipped image?

I was able to do that (still not quite right) by sending this to
vtkImageToStructuredPoints, but I do not think this would be necessary.

Thanks.
