Detailed Description

template<unsigned int VImageDimension>
class otb::ImageRegionTileMapSplitter< VImageDimension >

Divide a region into several pieces.

ImageRegionTileMapSplitter divides an ImageRegion into smaller regions. ImageRegionTileMapSplitter 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).

This ImageRegionTileMapSplitter class divides a region along the outermost dimension. If the outermost dimension has size 1 (i.e. a volume with a single slice), the ImageRegionTileMapSplitter will divide the region along the next outermost dimension. If that dimension has size 1, the process continues with the next outermost dimension.

Regions obtained by the ImageRegionTileMapSplitter are aligned on a grid with width of 256. Divisions can occur only at line defined as k*256.

Other ImageRegionTileMapSplitter subclasses could divide an image into more uniform shaped regions instead of slabs.

overridevirtual

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.
