Support operations that do processing in the frequency domain
Submitted by Jon Nordby
Link to original bug (#660735)
Description
Some image processing operations can only be done, or are best done in the frequency domain. GEGL needs to support these, and should provide facilities for writing such operations.
Work was done on this in 2008 as a GSOC project. It can be found in the branch gsoc2008-frequency-domain: http://git.gnome.org/browse/gegl/log/?h=gsoc2008-frequency-domain
Main blocker for integrating that work is the use of a GPL library for FFT. It need to be ported to use a library that allows GEGL to continue to be LGPL. For instance kissFFT: http://kissfft.sourceforge.net/
Version: git master
