Summary0001898: vtkImageIterator / GetScalarRange does not play well
DescriptionThe following code does not work:

void FillImage(vtkImageData *im, int ext[6], int timestep)
{
  vtkImageIterator<signed char> it(im,ext);
  while (!it.IsAtEnd())
    {
    signed char* imSI = it.BeginSpan();
    signed char* imSIEnd = it.EndSpan();

    while (imSI != imSIEnd)
      {
      *imSI = (signed char)timestep;
      ++imSI;
      }
    it.NextSpan();
    }
  im->GetPointData()->Modified();
  im->Modified();
}


int main()
{
  vtkImageData *im = vtkImageData::New();
  int ext[6] = {0,10,0,10,0,10};
  im->SetExtent(ext);
  im->SetScalarType ( VTK_SIGNED_CHAR );

  FillImage(im, ext, 0);
  double *range = im->GetScalarRange();
  std::cerr << range[0] << "," << range[1] << std::endl;
  std::cout << "V=" << im->GetScalarComponentAsDouble ( 0, 0, 0, 0) << std::endl;


  FillImage(im, ext, 100);
  double *range = im->GetScalarRange();
  std::cerr << range[0] << "," << range[1] << std::endl;
  std::cout << "V=" << im->GetScalarComponentAsDouble ( 0, 0, 0, 0) << std::endl;
}
