Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 6058 of file processor.h. 06059 { 06060 return "Make an image consisting of a single cross"; 06061 }
|
|
Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 6053 of file processor.h. 06054 {
06055 return NAME;
06056 }
