Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 5747 of file processor.h. 05748 {
05749 return "Iterative expansion of a binary mask, val1 is number of pixels to expand, if val2!=0 will make a soft Gaussian edge starting after val2 pixels.";
05750 }
|
|
|
Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 5742 of file processor.h. 05743 {
05744 return NAME;
05745 }

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.
