[ITK] (no subject)

[Michka Popoff]

Hi

for the moment, the PyBuffer module has been moved out of ITK, and is no more maintained.
There was a port done for ITK4, but it is not tested so I don’t know how well it is working [1]
I plan to work a little bit on it one day if I can find some time.

The way to move images from itk to vtk is to use the ITKVTKGlue module.
You need to build ITK with:
Module_ITKVtkGlue=ON

Then you can do something like this (for a 2d image for example):

image_type = itk.Image[itk.UC, 2]
reader = itk.ImageFileReader[image_type].New()
reader.SetFileName(“PATH/TO/FILE”)
reader.Update()
vtk_image = itk.ImageToVTKImageFilter[image_type].New()
vtk_image.SetInput(reader.GetOutput())
vtk_image.Update()

Then you can use the vtk_image as a vtk object, that you can render or work on.

Is there a specific error message you get ?
