Detailed Description

template<unsigned int VDimension>
class itk::ThreadedImageRegionPartitioner< VDimension >

Class for partitioning of an ImageRegion.

This class provides threading over an ImageRegion. It provides a SplitRequestedObject method that splits the provided ImageRegion into subregions, along the z-axis. Additionally it makes setting up a threaded operation easier.

Call SetOverallRegion to define the ImageRegion over which to thread. Call SetThreadedGenerateData to define the worker callback function, which is called from each thread with a unique region to process.

Warning: This callback function must be static if it is a class method.

Call SetHolder to provide a pointer to DataHolder object to store arbitrary user data for use in the threader callback (typically a class instance).

Call GenerateData to begin threaded processing.

This class is templated over image dimension and DataHolder type. The third template parameter TDomain should always be left as default.

Warning: The actual number of threads used may be less than the requested number of threads. Either because the requested number is greater than the number available, or the SplitRequestedObject method decides that fewer threads would be more efficient. After the threader has run, m_NumberOfThreadsUsed holds the actual number used. See DetermineNumberOfThreadsToUse to get the number of threads before running.
