Light and shadow centroids

This Python plug-in helps in the comparison of the left part of an image to the right part (equilibrium or not). It can be applied to any type of image and computes the centroid of the gray image pixels. The centroid is similar to the centre of mass concept, where mass is replace by another quantity; here it is the lightness and the greyness of the pixel.

Black & White variations to layers

This script creates predefined black and white variations and saves them as layers. Users can choose which variations should be created.

For more sophisticated possibilities use the channel mixer or other tools. This script just uses typical black and white variations, to provide a quick overview - just switch the layers visibility afterwards.

Install to .gimp-2.6/scripts in your homedir as bwvariations.scm, then start GIMP or click Script-Fu->Script refresh, you'll find it then under Script-Fu->Misc->bwvariations

Golden-ratio circle effect

This plugin takes an existing image (i.e. a petal) and creates a new one by placing the original repetitively in the new one while rotating and scaling the successive copies (typically rotating the golden angle of 137.5° and scaling down just a little bit each step) resulting in beautiful forms that resemble the work of nature (i.e. a flower)

It can be also used to create animations of spiral falling objects, and other funny things.

Layer to selection (select layer bounds)

Adds a new menu item

Select→Layer to selection

which creates a selection that exactly matches the boundaries of the current layer.

Mirrored frame/border

Creates a frame/border outside the image; the frame mirrors the original image.

The menu item appears in

Filters→Decor→Mirror frame

Rotation Animation

This script helps create simple rotating animations.

It asks for the desired number of animation frames (between 4 and 24 frames in increments of 4), and generates the corresponding number of layers each containing a rotated version of the image's background layer.
A choice of animation motion (circular and pendulum) is provided.

It has been tested in Gimp 2.6.11 on GNU/Linux and 2.8 on Windows XP.

Released v1.11 on 2012-07-02.

* Added pendulum motion
* fixed issue from lingering test code

True PseudoGray

A script-fu implementation of the Pseudogrey encoding as presented originally by Rich Franzen, and brought to my attention by user lylejk in this thread.

I've written up a blog post as well detailing the method and how it's derived.
