Member Function Documentation

virtual string EMAN::TestImageScurve::get_desc  )  const [inline, virtual]
 

Get the descrition of this specific processor.

This function must be overwritten by a subclass.

Returns:
The description of this processor.

Implements EMAN::Processor.

Definition at line 6166 of file processor.h.

06167                 {
06168                         return "Replace a source image with a lumpy S-curve used for alignment testing";
06169                 }

virtual string EMAN::TestImageScurve::get_name  )  const [inline, virtual]

Each processor is identified by a unique name.

Returns:
The processor's name.

Implements EMAN::Processor.

Definition at line 6161 of file processor.h.

06162                 {
06163                         return NAME;
06164                 }

virtual TypeDict EMAN::TestImageScurve::get_param_types  )  const [inline, virtual]
 

Get processor parameter information in a dictionary.

Each parameter has one record in the dictionary. Each record contains its name, data-type, and description.

Returns:
A dictionary containing the parameter info.

Reimplemented from EMAN::Processor.

void TestImageScurve::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.
