Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 671 of file processor_sparx.h. 00672 { 00673 return "Lowpass tanh filter processor applied in Fourier space. 0.5*(tanh(cnst*(S+omega))-tanh(cnst*(S-omega))). omega==cutoff_abs. cnst==pi/(2*fall_off*omega). S in terms of Nyquist=0.5."; 00674 }

|
Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 667 of file processor_sparx.h. 00668 { return NAME; }
|
|
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.
