Pb with vtkImageData (still does not work)

[Wilfrid Lefer]

Dear Charles,
I tried both the SetWholeExtent() method and to copy the ImageData
information but neither gave a positive result. Here is my code now:

vtkTIFFReader r
  r SetFileName titi.tif
  r Update
  set scals1 [[[r GetOutput] GetPointData] GetScalars]
vtkScalars scals2
  scals2 SetDataType [$scals1 GetDataType]
  scals2 SetNumberOfComponents [$scals1 GetNumberOfComponents]
  scals2 SetNumberOfScalars [$scals1 GetNumberOfScalars]
  scals2 SetData [$scals1 GetData]
vtkImageData i
  i CopyStructure [r GetOutput]
  [i GetImageInformation] Copy [[r GetOutput] GetImageInformation]
  set ext [[r GetOutput] GetWholeExtent]
  i SetWholeExtent [lindex $ext 0] [lindex $ext 1] [lindex $ext 2]
[lindex $ext 3] [lindex $ext 4] [lindex $ext 5]
  [i GetPointData] SetScalars scals2
vtkTIFFWriter w
  w SetFileName titi2.tif
  w SetInput i
  w Write
puts "Done"
