Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 5825 of file processor.h. 05826 { 05827 return "Iterative expansion of a binary mask, val1 is number of pixels to expand, if val2!=0 will make a soft Gaussian edge starting after val2 pixels."; 05828 }

Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 5820 of file processor.h. 05821 {
05822 return NAME;
05823 }

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.
