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.

Get processor parameter information in a dictionary. Each parameter has one record in the dictionary. Each record contains its name, data-type, and description.

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.
