Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 6015 of file processor.h. 06016 { 06017 return "Make a gradient image of the form y=mx+b, where x is any of the image axes."; 06018 }

Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 6010 of file processor.h. 06011 {
06012 return NAME;
06013 }

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.
