Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 6538 of file processor.h. 06539 {
06540 return "Replace a source image as a cylinder";

Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 6533 of file processor.h. 06534 {

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.
