Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Reimplemented in EMAN::NSigmaClampingProcessor. Definition at line 1559 of file processor.h. 01560 { 01561 return "This function clamps the min and max vals in the image at minval and maxval, respectively. In a sense this a bi-truncation of the data."; 01562 }

|
Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Reimplemented in EMAN::NSigmaClampingProcessor. Definition at line 1539 of file processor.h. 01540 {
01541 return NAME;
01542 }

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.
