[vtkusers] Pointer to pixels.

[Jordi Inglada]

Hello all.

I am taking my first steps with Vtk. Since I have a considerable
amount of code written by myself for image processing stuff, I would
like to reuse it together with vtk. In order to do this I need to put
the output of some image filters into, let's say, an array of
floats. If aFilter->GetOutput() returns a pointer of type
vtkImageData, how can I individually access the pixels?

Thanks.
