Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Reimplemented in EMAN::LaplacianProcessor, and EMAN::ZeroConstantProcessor. Definition at line 2846 of file processor.h. 02847 {
02848 return "AreaProcessor use pixel values and coordinates of a real-space square area. This is the base class. Specific AreaProcessor needs to implement function create_kernel().";

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.
