Gimp 3 Plug-in Installation - RESOLVED

oldmangrumpy · **Posted:** Mon Mar 24, 2025 6:04 pm **(#1)**

GIMP Version: 3.0.0-1
Operating System: Windows
GIMP Experience: Experienced User

Contrary to my initial decision to wait on GIMP 3, I have now downloaded it and will slowly configure it to work with all the plug-ins I have accumulated over many years.

But at the first step I have encountered problems as identified below. I would appreciate some counsel on my actions, which were as follows.

I checked the Preferences for the target plug-ins folders:

I copied a bunch of ofnuts plug-ins, dealing with layers, paths and his 'addoncollection' manager and pasted them into: Users\Tony\AppData\Roaming\GIMP\3.0\plug-ins

I open GIMP 3 and those plug-ins are nowhere to be seen.

EDIT - well I have now downloaded the ZIP archive for GMIC QT and put the folder into the same plug-in location as identified above. Open GIMP 3 and GMIC QT appears in the filters menu. It's all got me beat!

Typically you cannot use gimp 2 plugins in gimp 3.

To start, Ofnuts' Gimp 3.0 Tools are here:
https://sourceforge.net/projects/gimp3- ... s/general/
If you scroll down the page there are installation instructions.
It explains the directory structure to use.

Many scm that depend on python or filters that are now ported to GEGL are no longer functional. For instance my Embroider Stitcher scm plug-in no longer works with Noise>Spread.

My Chisled Steel effect scm plugin depended on LayerFx-210.py and no longer works.

Have to rewrite with some different filters i guess.

I am working on getting a few of mine working in Gimp-3.0 now.
I'm not sure how to use GEGL filters in my scripts though because nothing shows in the PDB.

Some examples for how to handle GEGL filters are here

Maybe that helps a bit

So in scm it would be written something like this?

Code: Select all

#!/usr/bin/env gimp-script-fu-interpreter-3.0

(define (script-fu-embroidery-stitcher image drawable contrast)
  (gimp-context-push)
  (gimp-image-undo-group-start image)
  
              (let* ((emlayer (car (gimp-layer-new-from-visible image image "Embroided layer"))))
                  ;copy the image to a new layer and name it
                (gimp-image-insert-layer image emlayer 0 0)


;Get the first layer of the first image
(gimp-get-images 0)
(image-get-layers 0)

;Create filter
(gimp-drawable-filter-new RUN-NONINTERACTIVE emlayer gegl-noise spread)

;Set properties
(filter-config-set-property ("horizontal"  7))
(filter-config-set-property ("vertical" 7))

;Apply filter
(layer-merge-filter (filter))

;rest of code here

Or perhaps it is time to learn python.
