Hello Walid,
Changing the default number of components per pixel of a filter's output
has to happen before memory allocation (I guess it will fail if you do it
in ThreadedGenerateData method).
You might add a "this->GetOutput()->SetNumberOfComponentsPerPixel(number)"
in the GenerateOutputInformation method. This should work because this
method precede buffer allocation.
Hope this helps!
