Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 3891 of file processor.h. 03892 {
03893 return "zero edges of image on top and bottom, and on left and right.";
03894 }

Get the processor's name. Each processor is identified by a unique name.

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.
