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 }

|
Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 6290 of file processor.h. 06291 {
06292 return NAME;
06293 }

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.
