[vtkusers] VtkImageClip : How to get it work ?

[Vincent Daanen]

Hi all,

I try to clip images interactivelly with a GUI (4 sliders).

so :
    I get the extent limits
    I set the vtkImageClip SetOutputWholeExtent method parameters
    and I call the Update method

a popup window raise with this error message : Update extent does not 
lie within whole extent

a Google Search points out a threads in the vtkuser mailing list but no 
answers !

So why does vtkImageClip raise this error ? and what should I do to use it ?

 thanks

 Vince
