Get the description of this group of processors. This function is defined in a parent class. It gives a introduction to a group of processors.
Reimplemented from EMAN::Processor. Definition at line 321 of file processor.h. 00322 { 00323 return "An Image Processor defines a way to create a processor image. The processor image is used to multiply the input-image in the fourier space. ImageFilter class is the base class. Each specific ImageFilter class must define function create_processor_image(). "; 00324 }

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.
