itk-vtkglue swig error

SiPyWiFi · July 21, 2020, 2:07pm

Hi,

If i import the itk.ImageToVTKFilter(), I get the error:
AttributeError: module 'itk.ITKVtkGluePython' has no attribute 'swig'

I am using:

itk==5.1.0.post3
vtk==8.1.2
itk-vtkglue==0.3.0

How can i solve this error?
All packages are installed using pip.
( pip install --upgrade itk-vtkglue)

Kind regards,
Simon

Hi Simon,

The itk-vtkglue module is not available for itk-5.1. Please help test this function, itk.vtk_image_from_image , which will ship with itk-5.2:

github.com

InsightSoftwareConsortium/ITK/blob/fe92a3aa8d6d304b2636f4ba90aa6b8b24f66974/Wrapping/Generators/Python/itkExtras.py#L481-L516


def vtk_image_from_image(image):
    """Convert an itk.Image to a vtk.vtkImageData."""
    import itk
    import vtk
    from vtk.util.numpy_support import numpy_to_vtk

    array = itk.array_view_from_image(image)

    vtk_image = vtk.vtkImageData()
    data_array = numpy_to_vtk(array.reshape(-1))
    data_array.SetNumberOfComponents(image.GetNumberOfComponentsPerPixel())
    data_array.SetName('Scalars')
    # Always set Scalars for (future?) multi-component volume rendering
    vtk_image.GetPointData().SetScalars(data_array)
    dim = image.GetImageDimension()
    spacing = [1.0,] * 3
    spacing[:dim] = image.GetSpacing()
    vtk_image.SetSpacing(spacing)
    origin = [0.0,] * 3
    origin[:dim] = image.GetOrigin()

Hi, Matt,

Many thanks for the quick response.
I’m integrating the function.
