void AddMaskShellProcessor::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.

Parameters:

image

The image to be processed.

Implements EMAN::Processor.
