I couldn’t get the Gimp “Reflection” filter to work (on Gimp 2.8), so after a little digging around I found that the GimpHelp.org website has kept some of the Gimp scripts — called Script-Fu scripts — up to date. So I downloaded those scripts, and then had to figure out how to make them work in Gimp on MacOS.
This is actually pretty easy. This Gimp.org page shows what you have to do. Just do this:
- Go to Preferences > Folders > Scripts to figure out where to put the scripts.
- Copy the scripts into that directory.
- Then restart Gimp (which I recommend), or run Filters > Script-Fu > Refresh Scripts to get those new scripts working.
On my MacOS system, this folder is /Users/Al/Library/Application Support/GIMP/2.8/scripts. To get to this folder with the Mac Finder you may have to go to the Finder, then click the “Go” menu, then “Go to Folder,” then paste this path into it: ~/Library/Application Support/Gimp.
If you’re wondering what these scripts do, see the end of my article titled A catalog of 130+ Gimp filters/effects. On that page I show about ten examples of what these “Script-Fu” scripts/filters can do.
