Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 546 of file processor.h. 00547 { 00548 return "Determines the image gradient in the x direction"; 00549 }

Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 534 of file processor.h. 00535 {
00536 return NAME;
00537 }

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.
