Hi Yasser,
I also had this problem. Try to update Insight from CVS with tag =
"ITK-1-6"
and rebuild.

Subject: [Insight-users] itk with vtk question ?
Hi all,
I compiled vtk 4.5, itk 1.6 for c++ and python and i compiled the =
application which do the connection between itk and vtk in python ...
but when i write my first application in python i have this error :
error message:
> Executing: C:\Program Files\ConTEXT\ConExec.exe =
"C:\Creatis\Python22\python.exe" "F:\Programs\python\itk\2\test.py"
Traceback (most recent call last):
File "F:\Programs\python\itk\2\test.py", line 19, in ?
CVIPy.ConnectVTKToITKF2(vtkExporter,itkImporter.GetPointer())
TypeError: Type error. Expected =
_p_itk__VTKImageImportTitk__ImageTfloat_2_t_t
> Execution finished.
i dont know what i can do for that .
note : i compiled the same version of vtk and itk 1.4 and the same =
application (in itk 1.4) it work ....
this is my application in python :
import InsightToolkit as itk
import vtkpython as vtk
import ConnectVTKITKPython as CVIPy
reader =3D vtk.vtkPNGReader()
reader.SetFileName("Brain.png")
imageCast =3D vtk.vtkImageCast()
imageCast.SetOutputScalarTypeToFloat()
imageCast.SetInput(reader.GetOutput())
imageCast.Update()
vtkExporter =3D vtk.vtkImageExport()
vtkExporter.SetInput(imageCast.GetOutput())
itkImporter =3D itk.itkVTKImageImportF2_New()
CVIPy.ConnectVTKToITKF2(vtkExporter,itkImporter.GetPointer())
thr=3Ditk.itkThresholdImageFilterF2_New()
thr.SetInput(itkImporter.GetOutput())
thr.ThresholdOutside(200,229)
thr.SetOutsideValue(0)
thr.Update()
rescaler =3D itk.itkRescaleIntensityImageFilterF2US2_New()
rescaler.SetInput(thr.GetOutput())
rescaler.SetOutputMinimum(0)
rescaler.SetOutputMaximum(255)
rescaler.Update()
itkExporter =3D itk.itkVTKImageExportUS2_New()
itkExporter.SetInput(rescaler.GetOutput())
vtkImporter =3D vtk.vtkImageImport()
CVIPy.ConnectITKUS2ToVTK(itkExporter.GetPointer(), vtkImporter)
Viewer=3Dvtk.vtkImageViewer()
Viewer.SetInput(vtkImporter.GetOutput())
Viewer.SetZSlice(0)
Viewer.SetColorWindow(255)
Viewer.SetColorLevel(128)
Viewer.Render()
RenWinInt=3Dvtk.vtkRenderWindowInteractor()
Viewer.SetupInteractor (RenWinInt)
RenWinInt.Initialize()
RenWinInt.Render()
RenWinInt.Start()
vtkwriter =3D vtk.vtkPNGWriter()
vtkwriter.SetFileName('testout.png')
vtkwriter.SetInput(vtkImporter.GetOutput())
vtkwriter.Write()
thanks in advance
