Script-Fu

The original scripting extension.

Animation Unstrip

The purpose of this script is to convert animation strips or sheets back into collections of layers. These can be saved as an animated GIF image or used for any other purpose.

Anaglyph to Stereo Pair (cross-eye)

There were a few anaglyph 3D images that I wanted to view as cross-eyed stereo pairs (I don't have glasses handy). I started doing the manipulations by hand to convert them from anaglyphs, then got tired of doing it manually.

So, I wrote a quick script-fu to do it for me. This will take a 3D Anaglyph image (red/cyan), and create a stereo pair (monochrome) for you...

Just load up an image, and run:

Filters > Generic > Anaglyph to Stereo...

Color Decompose (For B&W Conversions)

As part of writing the next part of my tutorials on B&W conversion, I needed to quickly decompose an RGB image into different grayscale channels based on useful channels from all the color modes (RGB, CMY(K), LAB, HSV, HSL, YCbCr).

It was tedious doing it by hand, so I wrote up this small script to automatically decompose an RGB image layer (active) into each of the color decomposition modes, and to keep the most useful to me for B&W conversions.

BgMask: extract still background from video frames / mask frames against background

May 21, 2013: BgMask 0.3 is released!

Video tutorial: http://www.youtube.com/watch?v=h7uJUiyJ1yw

This script adds several tools under Script-Fu - BgMask: "Extract background...", "Mask against background...", "Average linked layers...", and in BgMask 0.2 there are also "Extract background manually" and "Mask adjustments...". It can be used to mask moving objects/characters from animations with still background.

BgMask 0.3 introduces a new tool, "Blend Edges" which allows your masked objects to blend seamlessly into different backgrounds. Also, it improves the denoising algorithm of Mask Adjustments and adds a "Smoothen via paths" option.

Create water ripple

This script-fu creates water ripples.

Dodge & Burn layer

This simple script add a new layer on top of the image filled with neutral grey and in overlay mode. You can use this layer with the dodge and burn tool to work on shadows and highlights without destroying datas.

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

Quick sketch RGB

I modified the script quick-sketch.scm of tuxcomputers, so it does not transform the image into grayscale, but leave the image in RGB mode.

The location of the script is "Script Fu / Artistic / Quick Sketch RGB"
