[vtkusers] Error in pipeline point

[Glauco]

Hi all,
I´m with a problem in the execution of my program.
An error is occuring and my program is closing and this message appears : 'python.exe error'
I´m openning a lot of images with vtkImageReader. ( about 400 slices with spaccing : (0.5,0.5,0.3) extent ( 0, 511, 0, 511, 1, 400) )
the error occurs when the pipeline is in this point :

        fator = 2
        magnify = vtkImageMagnify()
        
        magnify.AddObserver("StartEvent", lambda obj, event: ProgressBar.StartProgress("Magnify image..."))
        magnify.AddObserver("ProgressEvent", ProgressBar.UpdateProgress)
        magnify.AddObserver("EndEvent", ProgressBar.EndProgress)
        
        magnify.SetInput(reader.GetOutput())
        magnify.SetMagnificationFactors(self.fator,self.fator,1)
        magnify.SetInterpolate(1)
        magnify.Update()
                
        print magnify.GetOutput()         
                 
        imageColors = vtkImageMapToColors()
        
        imageColors.AddObserver("StartEvent", lambda obj, event: ProgressBar.StartProgress("Color image..."))
        imageColors.AddObserver("ProgressEvent", ProgressBar.UpdateProgress)
        imageColors.AddObserver("EndEvent", ProgressBar.EndProgress)

        imageColors.SetInput(magnify.GetOutput())
        imageColors.SetLookupTable(mapaLabel.ilut)
        imageColors.Update()

exactly in vtkImageMapToColors !!!
the image data in vtkImageManify that I print with magnify.GetOutput is :
