Member Function Documentation

virtual string EMAN::PhaseToMassCenterProcessor::get_desc (  )  const [inline, virtual]

Get the descrition of this specific processor.

This function must be overwritten by a subclass.

Returns:
The description of this processor.

Implements EMAN::Processor.

05033                                 return "centers the image the center of mass, which is calculated using Fourier phases, ignores old dx, dy.";
05034                         }

virtual string EMAN::PhaseToMassCenterProcessor::get_name (  )  const [inline, virtual]

Get the processor's name.

Each processor is identified by a unique name.

Returns:
The processor's name.

Implements EMAN::Processor.

Definition at line 5021 of file processor.h.

void PhaseToMassCenterProcessor::process_inplace ( EMData image  )  [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.
