A small gimp scheme script for quickly creating an outline for the current layer. This small script was mostly made by me to practice some Lisp/Scheme via GIMP and also making a common task I do in GIMP more convenient to do.
Download the script-fu-outline.scm file from the release page or download it directly
Locate your script folder in Gimp via Edit -> Preferences -> Folders -> Scripts
There you can find the paths to your script folder(s) or create a new one
copy the path to the folder and put the script-fu-outline.scm file into that folder.
Then go to Filters -> Script-Fu -> Refresh Scripts and the script should be loaded now.
You can find the script under Edit -> Outline Current Layer...
