Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 6767 of file processor.h. 06768 { 06769 return "Multiply a real-space image by a radial function. 1 value / pixel, extending to corner. Missing values -> 0."; 06770 }

Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 6750 of file processor.h. Referenced by process_inplace(). 06751 {

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.
