Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 6541 of file processor.h. 06542 { 06543 return "Replace a source image as a circle or sphere depends on 2D or 3D of the source image"; 06544 }

Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 6536 of file processor.h. 06537 {

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.
