Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 6295 of file processor.h. 06296 { 06297 return "Replace a source image as a square or cube depends on 2D or 3D of the source image"; 06298 }

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.
