[ITK] [ITK-users] Using ITK python wrapper

Tue Apr 1 10:23:03 EDT 2014

Hi Nicole,

The file

  C:/Toolkits/ITK-4.5.1/build_x64_VS2008_withLTK/Wrapping/Generators/Python/WrapITK.pth

should be copied to

  C:/Python27/Lib/site-packages

In order to import the module, Python must be able to see the *.py
files and the _* C extensions, which are the swig C extension
interface that get imported by the *.py files, and the _* C extension
modules must be able to load the ITK DLL's that they use.

HTH,
Matt
