Dear all,
               I've a 2D image (vtkImageData) and I want to extract a part from it, say a 3*3 part, I tried vtkExtractVOI and vtkExtractGrid but I don't know how to set the parameters to extract the required region.For example, vtkExtractVOI ::SetVOI() takes six integers do they represent the coordinates? if so how?
  thanks in advance,

Sneak preview the  all-new Yahoo.com. It's not radically different. Just radically better.
