A simple Outline effect for GIMP. It works by adding a border to the content of a layer.
- Create a text layer (or any other layer), and make it the active one
- Go to menu Filters → Decor → Outline Simple
- Download
outline-simple.py
- Copy it to your plugin folder ( typically
~/.gimp-2.8/plug-ins/
) - Restart GIMP
The effect can be performed manually without this plugin, this will just make it in a more automated fashion. The steps are: set alpha to selection, grow selection, create new transparent layer, move new layer down, fill selection, blur.
This has been tested on GIMP 2.8 on Linux
