Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 577 of file processor.h. 00578 { 00579 return "Determines the image gradient in the y direction"; 00580 }

Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 565 of file processor.h. 00566 {
00567 return NAME;
00568 }

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.
