Detailed Description

template<unsigned int VImageDimension>
class itk::ImageRegionMultidimensionalSplitter< VImageDimension >

Divide a region into several pieces.

ImageRegionMultidimensionalSplitter divides an ImageRegion into smaller regions. ImageRegionMultidimensionalSplitter 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 a region can support will 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).

ImageRegionMultidimensionalSplitter 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.

Member Function Documentation

template<unsigned int VImageDimension> virtual const char* itk::ImageRegionMultidimensionalSplitter< VImageDimension >::GetClassName (    )  const [virtual]

Run-time type information (and related methods). Reimplemented from itk::ImageRegionSplitter< VImageDimension >.

template<unsigned int VImageDimension> virtual unsigned int itk::ImageRegionMultidimensionalSplitter< VImageDimension >::GetNumberOfSplits (  const RegionType &    region, unsigned int    requestedNumber )  [virtual]

How many pieces can the specifed region be split? A given region cannot always be divided into the requested number of pieces. For instance, if the numberOfPieces exceeds the number of pixels along a certain dimensions, then some splits will not be possible. This method returns a number less than or equal to the requested number of pieces. Reimplemented from itk::ImageRegionSplitter< VImageDimension >.

template<unsigned int VImageDimension> virtual RegionType itk::ImageRegionMultidimensionalSplitter< VImageDimension >::GetSplit (  unsigned int    i, unsigned int    numberOfPieces, const RegionType &    region )  [virtual]

Get a region definition that represents the ith piece a specified region. The "numberOfPieces" specified should be less than or equal to what GetNumberOfSplits() returns. Reimplemented from itk::ImageRegionSplitter< VImageDimension >.

template<unsigned int VImageDimension> itk::ImageRegionMultidimensionalSplitter< VImageDimension >::itkStaticConstMacro (  ImageDimension   , unsigned    int, VImageDimension    )

Dimension of the image available at compile time. Reimplemented from itk::ImageRegionSplitter< VImageDimension >.

template<unsigned int VImageDimension> Pointer itk::ImageRegionMultidimensionalSplitter< VImageDimension >::New (    )  [static]

Method for creation through the object factory. Reimplemented from itk::ImageRegionSplitter< VImageDimension >.

template<unsigned int VImageDimension> void itk::ImageRegionMultidimensionalSplitter< VImageDimension >::PrintSelf (  std::ostream &    os, Indent    indent )  const [protected, virtual]

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from itk::ImageRegionSplitter< VImageDimension >.
