I want to use the functionality of the LineIterator class ([https://itk.org/Doxygen/html/classitk\_1\_1LineIterator.html](https://itk.org/Doxygen/html/classitk_1_1LineIterator.html)) in itk with Python (not simple-itk). However, the class seems to be not available in the itk namespace. Is that the case or how can I access the class?

ITK’s iterators are generally not available via Python wrapping because of significant overhead when accessing pixels via Python wrapper.
