[Insight-users] Converting US3 itk image to vtk

[Mathieu Stumpf]

Hello,

Using simple itk I was able to open a file and print properties, so I
know my file use unsigned short. By the way, does itk provide some
facilities to check this type ? As you must provide it to itk Image
constructors, this would be really handy to manage arbitrary type.

So, I recompiled the whole itk to wrappe US, but it still doesn't work :

        Traceback (most recent call last):
          File "/home/miv/stumpf/src/lampyre/Tests/OpeningImage.py", line 36, in <module>
            connector = itk.ImageToVTKImageFilter[InputImageType].New()
          File "/usr/local/lib/ITK-4.1/Python/itkTemplate.py", line 233, in __getitem__
            raise KeyError, 'itkTemplate : No template %s for the %s class' % (str(parameters), self.__name__)
        KeyError: "itkTemplate : No template [<class 'itkImagePython.itkImageUS3'>] for the itk::ImageToVTKImageFilter class"
        
        Looks like itk::ImageToVTKImageFilter US3 wrapper isn't generated ! Did I miss some compilation option ?

Here is the code which produce the error :

        # system import
        import itk
        
        # local import
        from tools.Logorrhoea import logorrhoea as log # In short : wrapper for print
        
        file_path = str("/home/miv/stumpf/images/Normal002-DTI")
        
        # file reader
        InputImageType = itk.Image.US3
        log(dir(InputImageType))
        
        reader = itk.ImageFileReader[InputImageType].New()
        reader.SetFileName(file_path)
        log(reader)
        #
        #
        ## itk->vtk conversion 
        connector = itk.ImageToVTKImageFilter[InputImageType].New()
