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.

process_inplace()

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.
