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

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.

Create Layer Mask from...


GIMP 2.8 Python Plugin.
This plugin allows you to create layer mask from another layer mask.
Or create layer mask from grayscale copy of layer.

In addition, the main feature of this plugin - is an option that allows you to change the interaction between two masks (Replace, Subtract...):

acv2gimp: convert Photoshop curves to gimp format

This is not my script, I just found it and felt it should have a link from the registry:
https://github.com/suapapa/suapapa_snippets/blob/master/acv2gimp.py
It converts Photoshop curves files to Gimp format.

Example usage:
python2 acv2gimp.py mycurve.acv -o ~/.gimp-2.8/curves/mycurve.crv

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

Scale and move layer to canvas (layer-cover-image)

Adds a menu option

Layer→Scale and move layer to canvas

which scales the layer to canvas size, and moves it so it exactly covers the canvas.

Group change font

Change font and font size of all text layers within a group.

Group offset

It's basically the same as Layer > Transform > Offset, except it works on layer groups.

Frequency and/or Color Separation

One of the secrets of great image manipulation is to separate images into components. Frequency separation is often mentioned, breaking the image into so-called high-pass and low-pass layers. The high-pass layer separates out the sudden changes in an image and fiddling with this layer can enhance sharpening or even out blemishes. The low-pass layer can be used for smoothing out color transitions. Portrait photographers use this extensively for smoothing skin and removing spots. There is no native Frequency separation tool or filter built into gimp.

Move, Scale, and Rotate using paths as reference

This is a collection of four scripts which help with aligning layers for HDR and mask workflow, as well as simply scaling, moving, or rotating layers.
