Detailed Description

The base class for fourier space processor working on individual pixels.

ri2ap() is called before processing, so individual pixels will be A/P rather than R/I. The processor won't consider the pixel's coordinates and neighbors.

Member Function Documentation

static string EMAN::ComplexPixelProcessor::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.

Reimplemented from EMAN::Processor.

void ComplexPixelProcessor::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.
