Hello,
I try a simple program with the

	const unsigned int numberOfLevels = 2;
	typedef itk::Image< PixelType, Dimension >   
ImageType;
	
	
	typedef itk::ImageFileReader< ImageType > 
ReaderType;
	typedef itk::ImageFileWriter< ImageType > 
WriterType;
	ReaderType::Pointer reader = ReaderType::New();

	myPyramid->SetNumberOfLevels(numberOfLevels );
	myPyramid->SetInput(reader->GetOutput() ); 
	try {
	myPyramid->Update();
	}
