virtual EMData* EMAN::ImageProcessor::create_processor_image (  )  const [protected, pure virtual]

Referenced by process_inplace().

static string EMAN::ImageProcessor::get_group_desc (  )  [inline, static]

Get the description of this group of processors.

This function is defined in a parent class. It gives a introduction to a group of processors.

Returns:
The description of this group of processors.

void ImageProcessor::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.
