[vtkusers] Re: How to get 2D image slices from 3D vtk image data

[Alberto García Consuegra]

 Hi Jiangshan,
If you want to get some slices from a data volume (for example imageData),
you can use vtkExtractVOI.
First create extractVOI object
Second set the input data (imageData)
Third set the region you want to extract using selectVOI method
Fourth call update method of extractVOI object
Finally getOutput returns the image in a imageData object.
