Detailed Description

Divide an image region into several pieces.

ImageRegionSplitterBase is an abstract interface to divides an ImageRegion into smaller regions. ImageRegionSplitterBase is used by the ImageSource, StreamingImageFilter, streaming ImageIO classes to divide a region into a series of smaller subregions.

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).

How many pieces can the specified 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.

Get a region definition that represents the ith piece a specified region.

The numberOfPieces must be equal to what GetNumberOfSplits() returns. The return value is the maximum number of splits available. If i is greater than or equal to the return value the value of the region is undefined.
