A repository of extensions for GIMP, the FREE and Open Source image manipulation program.


A simple plug-in to do fourier transform on you image. The major advantage of this plugin is to be able to work with the transformed image inside GIMP. You can so draw or apply filters in fourier space, and get the modified image with an inverse FFT.

Wavelet sharpen

The wavelet sharpen plugin enhances apparent sharpness of an image by increasing contrast in high frequency space. The amount of unsharpness of the original image can be taken into account by adjusting the sharpening radius. As an option you can choose to sharpen the luminance (YCbCr) channel of the image only.

Eyeball - Updated for v2.6

This script will make a single eyeball, and has been updated for v2.6. The colors of the iris, and size of the pupil, lighter iris, and darker iris, are all adjustable. Ideally, the inner eye color should be about half the brightness of the outer eye color to provide a nice transition from the pupil, but any two colors can be used. The image itself can be anywhere from 300x300 to 3000x3000 in size. The eye will have a transparent background. Enjoy! The attached picture is what the final product will look like (your colors may vary, obviously!)

Red Filter Diving

This script acts as a red fitler on diving photos.
To launch it, goto the menu /Script-Fu/Enhance/Diving red filter

Basically, create a new layer containing the corrected picture
You can adjust the red level (sometimes, green might works better !)
and set if the white balance has to be performed...
Enjoy !

Scale in steps


"Scale in steps" resizes an image to the given dimensions in several steps to get a way sharper result compared to resizing in one step. The step size is given in percent and should range between seven and ten percent.


None of the sample images are sharpened. The original picture was 3000×2000.

Stepsize: 5%
Stepsize: 10%
Traditional scaling


Crop to center the selection

This script crops the image so that the current selection winds up at the center of the image. It is especially useful when postprocessing digital images: When the subject of a photograph appears off-center, simply select the subject, click on Script-Fu/Selection/Center Selection..., optionally customize the script's parameters (described below), et voilà—the subject is now perfectly centered.

Planetary Ring System - Updated for Gimp 2.6

This script makes a ring system that you can add to a picture of a planet, and was adapted from a Photoshop script. This script is updated for GIMP v2.6
The ring system can be any size from 300x300 to 3000x3000, and can be tilted to any angle. The whirl-and-pinch portion of the script is time consuming, but using at least 8 iterations make the rings look very nice. The thickness of the rings can be controlled using the inner and outer ring ratio values in the script. The closer these two values are together, the narrower the ring.
