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.

Implements EMAN::Processor.

virtual string EMAN::TestImageScurve::get_name

(

)

const [inline, virtual]

Get the processor's name.

Each processor is identified by a unique name.

Returns:

The processor's name.

Implements EMAN::Processor.

Definition at line 5752 of file processor.h.

                {
                        return "testimage.scurve";
                }

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 5757 of file processor.h.

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

                {
                        return new TestImageScurve();
                }

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.
