+Plugin GIMP : Fourier Transform
+
+I.   What it does
+
+ It does a direct and reverse Fourier Transform.
+ It allows you to work in the frequency domain.
+ For instance, it can be used to remove moir� patterns from
+images scanned from books. (See README.Moire)
+
+II.  Use 
+
+ It adds menu items :
+  Filters/Generic/Foward FFT
+  Filters/Generic/Inverse FFT
+
+III. Installation
+
+ Linux:
+   make
+   make install
+
+   You will need the fftw3 package, and the development packages 
+    of gimp, fftw3, and glib.
+
+ Win32: 
+
+  Binaries for win32 are provided (in a separate package), just copy the files
+  in the plugins directory of :
+   your personal gimp directory (ex: .gimp-2.2\plug-ins), 
+   or in the global directory (C:\Program Files\GIMP-2.2\lib\gimp\2.0\plug-ins)
+
+   If you don't have fftw3 installed on your system, you must download 
+   the provided fftw3.dll, and copy it where you stored the plugin.
+
+   You can compile it with the free environment DevCPP (mingw compiler). 
+   You will need several DevPak : fftw3, GTK and gimp-dev (available on 
+   devpaks.org). gimp-dev is designed to work with binaries version of 
+
+History :
+ v0.1.1 : First release of this plugin
+ v0.1.2 : BugFixes by Mogens Kjaer <[email protected]>, May 5, 2002 
+ v0.1.3 : Converted to Gimp 2.0 (dirty conversion)
+ v0.2.0 : Many improvements from Mogens Kjaer <[email protected]>, Mar 16, 2005
+              * Moved to gimp-2.2
+              * Handles RGB and grayscale images
+              * Scale factors stored as parasite information
+              * Columns are swapped
+ v0.3.0 : Great Improvement from Alex Fern�ndez with dynamic boosting :
+              * Dynamic boosted normalization : 
+                    fft/inverse loss of quality is now un-noticeable 
+              * Removed the need of parasite information
+ v0.3.1 : Zero initialize padding (patch provided by Rene Rebe)
+ v0.3.2 : GPL, Fixed Makefile with pkg-config
+ v0.4.0 : Patch by Edgar Bonet :
+             * Reordered the data in a more natural way
+             * No Fourier coefficient is lost
+
+Many thanks to Mogens Kjaer, Alex Fern�ndez, Rene Rebe and Edgar Bonet 
+for their contributions.

+This plug-in to Gimp does a FFT of an image.
+
+I've used this with success to remove moir� patterns from
+images scanned from books:
+
+The image should be in RGB. Remove the alpha layer,
+this makes it easier (Layers|Flatten image).
+
+Select Filters|Render|FFT directe
+
+In the Layers window, select the layer, and "Duplicate Layer".
+
+Select Image|Colors|Brightness-Contrast. Increase Contrast so
+you can see the patterns.
+
+The area in the upper left and upper right is the FFT of the
+real image; don't modify this. The FFT of the moir� pattern
+is outside these regions. Use the Rectangular Selection or
+Elliptical Selection tools to select these regions.
+
+Remove the copy layer: This will leave the original FFT
+image with the selections.
+
+Choose (128,128,128) as the background color.
+
+Select Edit|Fill with BG color.
+
+Remove the selections from the image.
+
+Select Filters|Render|FFT inverse
+
+Voil�, now you have an image without the moir� pattern!
+
+It was originally written by R�mi Peyronnet <[email protected]>,
+I have corrected a few bugs in it.
