Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 609 of file processor.h. 00610 { 00611 return "Determines the image gradient in the z direction"; 00612 }

Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 597 of file processor.h. 00598 {
00599 return NAME;
00600 }

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.
