[ITK-users] Change codes from C++ supported ITK to Python supported ITK

[Matt McCormick]

Hi Zhuangming Shen,

For now, we need to reproduce the logic in itkSpatialOrientation.h
[1]. However, I created an issue to expose itk.SpatialOrientation in
Python [2].

Here is an example:

import itk

ITK_COORDINATE_UNKNOWN = 0
ITK_COORDINATE_Right = 2
ITK_COORDINATE_Left = 3
ITK_COORDINATE_Posterior = 4
ITK_COORDINATE_Anterior = 5
ITK_COORDINATE_Inferior = 8
ITK_COORDINATE_Superior = 9

ITK_COORDINATE_PrimaryMinor = 0
ITK_COORDINATE_SecondaryMinor = 8
ITK_COORDINATE_TertiaryMinor = 16

ITK_COORDINATE_ORIENTATION_RIP = ( ITK_COORDINATE_Right <<
ITK_COORDINATE_PrimaryMinor ) \
                               + ( ITK_COORDINATE_Inferior <<
ITK_COORDINATE_SecondaryMinor ) \
                               + ( ITK_COORDINATE_Posterior <<
ITK_COORDINATE_TertiaryMinor )

ImageType = itk.Image[itk.ctype('unsigned char'), 3]

orienter = itk.OrientImageFilter[ImageType, ImageType].New()
orienter.SetUseImageDirection(True)
orienter.SetDesiredCoordinateOrientation(ITK_COORDINATE_ORIENTATION_RIP)

HTH,
Matt
