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 less then or equal to the argumen 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.

virtual::itk::LightObject::Pointer itk::ImageRegionMultidimensionalSplitter< VImageDimension >::CreateAnother

(

void

)

const [virtual]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::ImageRegionSplitter< VImageDimension >.

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" must be equal to what GetNumberOfSplits() returns.

Reimplemented from itk::ImageRegionSplitter< VImageDimension >.

Method for creation through the object factory.

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.
