Member Function Documentation

virtual string EMAN::TestImageCirclesphere::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.

06247                         return "Replace a source image as a circle or sphere depends on 2D or 3D of the source image";
06248                 }

virtual string EMAN::TestImageCirclesphere::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 6240 of file processor.h.

06241                 {

void TestImageCirclesphere::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.
