Hi contrast
I'm glad you spent a month or two showing Gimpers how to use GEGL. Some of the effects could be achieved by other methods (like G'MIC). But GEGL is powerful and there is more to come for sure.
With GimpChat there are a lot of views but not so many comments. That means not many active participants at any one time.
Here is a script I made inspired by you that converts an animation folder of PNGs into a neon lights animation.
#!/bin/bash
mkdir ./done
for i in *.png
do
gegl $i -o ./done/$i -- bloom threshold=2 strength=350 edge-neon radius=1 amount=5 softglow glow-radius=0.1 brightness=0.1
done
The animation started as a Mandelbulber 3D fractal animation.
