Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 6330 of file processor.h. 06331 { 06332 return "Replace a source image as a circle or sphere depends on 2D or 3D of the source image"; 06333 }

Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 6325 of file processor.h. 06326 {
06327 return NAME;
06328 }

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.
