[Insight-users] How to get one 2d image from 3d volume data?

[jiang]

Dear ITK-users,
I read a series of 2d image files to form a 3d volume. Now I want to get one
slice of those images from the volume pointer. How should I do?
The type of volume is:
  typedef itk::Image<PixelType, 3>		  ImageNDType;
  ImageNDType::Pointer volume;

The 2d image type is:
  typedef itk::Image<PixelType, 2>        ImageType;
  ImageType::Pointer OnePiece.


Thank you very much!
