Superclass of all classes generating Images (instances of class Image) as output.
In itk and vtk the generated result of a ProcessObject is only guaranteed to be up-to-date, when Update() of the ProcessObject or the generated DataObject is called immediately before access of the data stored in the DataObject. This is also true for subclasses of mitk::BaseProcess and thus for mitk::ImageSource. But there are also three access methods provided that guarantee an up-to-date result (by first calling Update and then returning the result of GetOutput()): GetData(), GetPic() and GetVtkImageData().

If an imaging filter needs to perform processing after all processing threads have completed, the filter can can provide an implementation for AfterThreadedGenerateData().
The execution flow in the default GenerateData() method will be: 1) Allocate the output buffer 2) Call BeforeThreadedGenerateData() 3) Spawn threads, calling ThreadedGenerateData() in each thread. 4) Call AfterThreadedGenerateData() Note that this flow of control is only available if a filter provides a ThreadedGenerateData() method and NOT a GenerateData() method.

The GenerateData method normally allocates the buffers for all of the outputs of a filter.
Some filters may want to override this default behavior. For example, a filter may have multiple outputs with varying resolution. Or a filter may want to process data in place by grafting its input to its output.

overrideprotected |
A version of GenerateData() specific for image processing filters.
This implementation will split the processing across multiple threads. The buffer is allocated by this method. Then the BeforeThreadedGenerateData() method is called (if provided). Then, a series of threads are spawned each calling ThreadedGenerateData(). After all the threads have completed processing, the AfterThreadedGenerateData() method is called (if provided). If an image processing filter cannot be threaded, the filter should provide an implementation of GenerateData(). That implementation is responsible for allocating the output buffer. If a filter an be threaded, it should NOT provide a GenerateData() method but should provide a ThreadedGenerateData() instead.

OutputType* mitk::ImageSource::GetOutput | ( | ) |
Get the output data of this image source object.
The output of this function is not valid until an appropriate Update() method has been called, either explicitly or implicitly. Both the filter itself and the data object have Update() methods, and both methods update the data. Here are three ways to use GetOutput() and make sure the data is valid. In these examples, image is a pointer to some Image object, and the particular ProcessObjects involved are filters. The same examples apply to non-image (e.g. Mesh) data as well.
In this situation, someFilter and anotherFilter are said to constitute a pipeline.
(In the above example, the two lines of code can be in either order.)
Note that Update() is not called automatically except within a pipeline as in the first example. When streaming (using a StreamingImageFilter) is activated, it may be more efficient to use a pipeline than to call Update() once for each filter in turn.
For an image, the data generated is for the requested Region, which can be set using ImageBase::SetRequestedRegion(). By default, the largest possible region is requested.
For Filters which have multiple outputs of different types, the GetOutput() method assumes the output is of OutputImageType. For the GetOutput(DataObjectPointerArraySizeType) method, a dynamic_cast is performed incase the filter has outputs of different types or image types. Derived classes should have named get methods for these outputs.

This is a default implementation to make sure we have something. Once all the subclasses of ProcessObject provide an appropriate MakeOutput(), then ProcessObject::MakeOutput() can be made pure virtual.

Make a DataObject of the correct type to used as the specified output.
Every ProcessObject subclass must be able to create a DataObject that can be used as a specified output. This method is automatically called when DataObject::DisconnectPipeline() is called. DataObject::DisconnectPipeline, disconnects a data object from being an output of its current source. When the data object is disconnected, the ProcessObject needs to construct a replacement output data object so that the ProcessObject is in a valid state. So DataObject::DisconnectPipeline eventually calls ProcessObject::MakeOutput. Note that MakeOutput always returns a SmartPointer to a DataObject. If a subclass of ImageSource has multiple outputs of different types, then that class must provide an implementation of MakeOutput().

This method is intentionally left blank.
ImageSource's need not Initialize their containers. The Image::Allocate() method (called from GenerateData()) will resize the container if more memory is needed. Otherwise, the memory can be reused.

Split the output's RequestedRegion into "num" pieces, returning region "i" as "splitRegion".
This method is called "num" times. The regions must not overlap. The method returns the number of pieces that the routine is capable of splitting the output RequestedRegion, i.e. return value is less than or equal to "num".

If an imaging filter can be implemented as a multithreaded algorithm, the filter will provide an implementation of ThreadedGenerateData().
This superclass will automatically split the output image into a number of pieces, spawn multiple threads, and call ThreadedGenerateData() in each thread. Prior to spawning threads, the BeforeThreadedGenerateData() method is called. After all the threads have completed, the AfterThreadedGenerateData() method is called. If an image processing filter cannot support threading, that filter should provide an implementation of the GenerateData() method instead of providing an implementation of ThreadedGenerateData(). If a filter provides a GenerateData() method as its implementation, then the filter is responsible for allocating the output data. If a filter provides a ThreadedGenerateData() method as its implementation, then the output memory will allocated automatically by this superclass. The ThreadedGenerateData() method should only produce the output specified by "outputThreadRegion" parameter. ThreadedGenerateData() cannot write to any other portion of the output image (as this is responsibility of a different thread).

Static function used as a "callback" by the MultiThreader.
The threading library will call this routine for each thread, which will delegate the control to ThreadedGenerateData().
