Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 71 of file processor_sparx.h. 00072 { 00073 return "Mirrors an image along the specified axis. This will shift the image center for even box sizes. Use the 'xform.flip' processor to preserve center."; 00074 }

|
Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 54 of file processor_sparx.h. 00055 {
00056 return NAME;
00057 }

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.
