00570                 { return new NewLowpassButterworthProcessor(); }

void EMAN::NewLowpassButterworthProcessor::process_inplace EMData image  )  [inline, virtual]
 

To process an image in-place.

For those processors which can only be processed out-of-place, override this function to just print out some error message to remind user call the out-of-place version.

Parameters:
image The image to be processed.

Implements EMAN::Processor.
