#include <itkImageRegionSplitterMultidimensional.h>

Detailed Description

Divide a region into several pieces.

ImageRegionSplitterMultidimensional divides an ImageRegion into smaller regions. ImageRegionSplitterMultidimensional is used by the StreamingImageFilter to divide a requested output region into a series of smaller requests of the pipeline. This object has two basic methods: GetNumberOfSplits() and GetSplit().

GetNumberOfSplits() is used to determine how may subregions a given region can be divided. You call GetNumberOfSplits with an argument that is the number of subregions you want. If the image region can support that number of subregions, that number is returned. Otherwise, the maximum number of splits less then or equal to the argument be returned. For example, if a region splitter class only divides a region into horizontal slabs, then the maximum number of splits will be the number of rows in the region.

GetSplit() returns the ith of N subregions (as an ImageRegion object).

ImageRegionSplitterMultidimensional class divides a region into hypercubes (as opposed to the slabs used by the superclass ImageRegionSplitter). In other words, it splits every dimension of the region to form ND rectangular prisms.
