ITK/Release 4.12

New Features

---

• Wrapping Improvements

 - Enable BridgeNumPy by default with Python wrapping
 - Build support for Microsoft Visual C++ Compiler for Python 2.7
 - BridgeNumpy integrates new pairs of functions. GetArrayViewFromImage() and GetImageViewFromArray() return views on the source object given as a parameter to the function. Memory is shared among input and output objects and the source object still manages pixel buffer memory. The existing functions GetArrayFromImage() and GetImageFromArray() perform a deep copy of the source object.
 - Similar NumPy bridge functions have been created for VNL matrices and VNL vectors.
 - Convenience functions imread() and imwrite() have been added to the Python itk namespace. These functions facilitate respectively reading and writing images using ITK without having to specify the input or output image component type. The naming of these functions follows the convention used in several other Python project such as scikit-learn and scipy.
 - Better integration in Jupyter Notebook: addressed tab completion bug for IPython >= 5.0.0, replaced underscore with ‘x’ to name attributes that start with a digit to show attributes when trying to autocomplete in IPython.
 - Wrap itkN4BiasFieldCorrectionImageFilter, NormalVariateGenerator, and PathToImageFilter.
 - Allows calling ImageFileWriter in Python with an ITK filter as input image argument.
 - Build Python wrapping with hidden visibility
