Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 6335 of file processor.h. 06336 { 06337 return "Insert an ellipse into the image."; 06338 }

Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 6330 of file processor.h. 06331 {

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.
