Public Member Functions
	BackgroundTaskTileProcessorBase ()

virtual	~BackgroundTaskTileProcessorBase ()
	Destructor.

Interface to reimplement.
virtual SubImageBox	getNextTileBox ()=0
	Reimplement to return the next tile's SubImageBox.

virtual bool	processTile (ManagedSubImage &image)=0
	Reimplement to process the given tile, return true if everything was ok.

virtual ManagedSubImage *	createExternalBuffer (const SubImageBox &box)
	Only needs to be reimplemented to allocate the memory for your tiles yourself, is only called if setAllocationPolicy() is called with TileRequest::ExternalBuffer.

Tile properties to setup.
void	setDataType (MLDataType dt)
	Set the datatype (if it is not set, it will use the input image datatype).

MLDataType	getDataType () const
	Get the datatype.

void	setInputImageIndex (int index)
	Set the input image from which data is requested (the default is 0).

int	getInputImageIndex () const
	Get the input image index.

void	setAllocationPolicy (TileRequest::AllocationPolicy policy)
	Set the allocation policy of the tiles that are passed to processTile() (The default is to use the MemoryManager).

void	setMaximumQueuedTiles (int size)
	Set the number of tiles that are allowed to be requested on the request queue.

Running the processing.
virtual bool	doProcessing (ModuleBackgroundTask &task)
	Start the processing, returns true if everything went fine.

Protected Member Functions
virtual bool	setupProcessing (ModuleBackgroundTask &)
	Needs to be reimplemented to setup things before doProcessing() requests tiles.

virtual bool	cleanupProcessing (ModuleBackgroundTask &)
	Needs to be reimplemented to cleanup things after doProcessing() finished processing tiles.

void	setNumTiles (MLint tiles)
	Set the number of tiles that will be processed.
