Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 3926 of file processor.h. 03927 { 03928 return "zero edges of image on top and bottom, and on left and right."; 03929 }

Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 3916 of file processor.h. 03917 {
03918 return NAME;
03919 }

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.
