static string EMAN::NormalizeProcessor::get_group_desc | ( | ) | [inline, static] |
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.

void NormalizeProcessor::process_inplace | ( | EMData * | image | ) | [virtual] |
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.
