[vtkusers] vtkImageReslice zoomed performance - no clipping?

[Henning Meyer]

Hi!

When using vtkImageReslice, I get very low performance, once I zoom
into an image. It seems, that vtkImageReslice is rendering a huge
virtual image, and is clipping after that, is that true? Could it be
changed to be clipped before? Also I found, the clipping is not always
correct, as sometimes with certain transforms the output image gets
clipped inside the render window.
Is there anything I could do here?

Thank you,

Henning
