[vtkusers] (no subject) (vtkImageWeightedSum)

Hi,

Since I could not find how to solve my problem, I've tried this : 
ITK image -> VTK Image -> vtkImageViewer -> wxVTKRenderWindowInteractor ->wxWindow
So basicly, I skipped the part with the vtkImageWeightedSum. It is what I was doing for testing before I had the CVS version and wanted to use vtkImageWeightedSum.

With CVS version, I still have the error I described below, but with the 5.0.1 vtk release everything goes well.

Does anyone has and idea of how I could solve this problem with the CVS version, because I have to use this vtkImageWeightedSum class, which is not available on the 5.0.1 release.

Thanks again.

Pierre
