Hi everyone,

I've been working on an open source plugin that brings ML powered background removal directly into GIMP 3.
Everything runs locally on your own machine. The plugin talks to a local withoutBG server (Docker or the macOS app), so your images never leave your computer.

Features
  • Works with GIMP 3
  • Fully open source (The model running on your computer is with open weights)
  • Runs locally
  • Creates a non destructive layer mask instead of permanently deleting the background
  • Supports macOS and Linux today (Windows should also work with a local Docker backend)

The workflow is:
  1. Open an image.
  2. Go to Tools > WithoutBG > Remove Background…
  3. The plugin generates a matte and applies it as a layer mask, so you can continue refining it using normal GIMP tools.

Documentation: Source code: I'd appreciate any feedback on:
  • Installation experience
  • UI/UX
  • Performance
  • Feature requests
  • Bugs or compatibility issues

I'm actively developing it and would be happy to improve it based on feedback from GIMP users.

If you find the plugin useful, I'd also appreciate a ⭐ on GitHub. It helps other GIMP users discover the project and motivates continued development.]]>

I ported some scripts that I had gotten off the registry in times gone past and which are part
of my workflow. I don't know if they are still being maintained and I contacted the authors
to see if I can send them the changes or if they moved on from them.

In the meantime, if you are using them or want to try them out, you can get them from this
github repo [1].

You can check them out on github. 
  • silicosaur (Baráth Gábor) film effect filters (only works on 3.2 due to bug in 3.0 re spline-curves)
    • silicosaur-photofx-velvia (Fujifilm Velvia 50)
    • silicosaur-photofx-provia (Fujichrome Provia chrome)
    • silicosaur-photofx-portra (Kodak Portra)
    • silicosaur-photofx-crossprocess (Cross process (x-pro) effect)
  •  Ryan Burnside filters for adding different kinds of guidelines (percent, golden-rule, centered,...)
    •  divide-thirds
The first commit I had made was the 2.10 version so you could see the changes to port them to 3.x. and use that as an example in porting other legacy scripts. Alas,  as I'm writing this, I realize that is lost in all but one plug-in because I squashed the branch commits for the other ones.

This was an interesting experience, learning scheme and GIMP plug-in's API.

Enjoy!

The plugin should now be more useful for general use: the hexagons centers alignment with the pixel grid can be bypassed if pixel-perfect rasterization is not needed. Vertical/horizontal lines are still always perfectly aligned to pixels, to avoid annoying blurriness.

As in previous versions, it offers the option to create nicely formatted sample sheet, if you need to choose visually the ideal size, along with the output of useful parameters. A new output is the number of contiguous hexagons and lines the current image can contain.

Anecdotally, for the mathematically inclined, these parameters output, and the filtering ability, can be used to search for the optimal discrete fractions which approximate square root of 3! ;-)

Download by clicking on https://github.com/Scallact/gimp-plugin-hexgrid, and the link under "Releases". Download the Source code at the bottom, and install it according to the description at the bottom of the Readme.


I invite you to read the documentation, as there are a few non trivial concepts and parameters.

I've just released a parametric masking plug-in for GIMP 3 and wanted to share it here.

The plug-in creates a layer mask from one of four source channels: Red, Green, Blue, or Luminance. You shape the mask using a tone curve with a live histogram. Drag points up to include tones, drag them down to exclude them. The canvas updates live as you work.

The curve approach gives you precise, automatically feathered control over the mask. Target midtones, create double peaks, or invert regions entirely. Since photographers already think in curves, there's no new mental model to learn.

The idea was inspired by Yasuo Ohnishi's parametric masking work for GIMP 3. My plug-in takes a different direction, using a curve editor instead of sliders.

A few highlights:

- Red, Green, Blue, and Luminance channel support
- Live preview on the canvas
- Whole-image mode and single-layer mode
- Non-destructive: works on a new layer, never touches the original
- Available in 14 languages
- Runs on Linux, Windows, and macOS

The plug-in creates a layer mask from one of four source channels: Red, Green, Blue, or Luminance. You shape the mask using a tone curve with a live histogram. Drag points up to include tones, drag them down to exclude them. The canvas updates live as you work.

The curve approach gives you precise, automatically feathered control over the mask. Target midtones, create double peaks, or invert regions entirely. Since photographers already think in curves, there's no new mental model to learn.

The idea was inspired by Yasuo Ohnishi's parametric masking work for GIMP 3. My plug-in takes a different direction, using a curve editor instead of sliders.

A few highlights:

- Red, Green, Blue, and Luminance channel support
- Live preview on the canvas
- Whole-image mode and single-layer mode
- Non-destructive: works on a new layer, never touches the original
- Available in 14 languages
- Runs on Linux, Windows, and macOS

I installed gimp3_upscale but when I restarted Gimp the plug-in did not show where the Git instructions said it should. My preferences show C:\Users\jack6\AppData\Roaming\GIMP\3.0\plug-ins AND C:\Users\jack6\AppData\Roaming\GIMP\3.0\plug-ins as plug-in directories. (Why 2 locations I am not sure, so I put the script directory in both.)  See screenshot.
 
It is supposed to show up under Filters>Enhance but it does not. This is the first plug-in I have loaded manually, so am I missing something ? 

GIT instructions simply say:
[*]1 Download the latest release:gimp3_upscale.zip

[*]for GIMP 3.0
2 Extract the plug-in folder into your GIMP plug-ins directory.
[*]3 Restart GIMP.

To use it 
[*]1 Open an image in GIMP.
[*]2 Go to Filters > Enhance > AI Upscale..

but that entry is not there.
Suggestions ?

NOTE: I just tried to use the Help > Plugin Browser and it does not find anything. Not sure if that helps. 
Thanks

Execution error for 'DoIt':

Does anybody know if the function gimp-image-get-filename has changed in Gimp 3.0, or if I'm missing something in my Gimp installation?

Thanks,

I've got to toggle layer visibility off then on for the display to refresh, or copy the modified pixels, paste back over themselves, and merge down.

I'm aware of the function "gimp-displays-refresh", but calling it doesn't seem to do anything.

I'm assuming I'm just very stupid and there's a simple way to make the results gimp-drawable-set-pixels visible from script-fu. I certainly feel stupid after spending so much time trying to figure out something so seemingly simple, so as a last resort I figured I'd ask here.  Wink]]> I have been exploring Script-Fu recently, and found that the procedure "gimp-drawable-set-pixels" sets the colours of pixels but does not make the new colours visible!

No longer can I search within the dock for a font, I either have to input into the tool options spelled exactly correctly or scroll endlessly through all the pre-installed system & language fonts I'm never ever ever ever going to use.

I want to... 1) get all these pre-installed system fonts out of this dock, period. They are useless me, there is so many they take up like at least 2/3 maybe 3/4 of the list, they just cause me to waste several minutes scrolling through them constantly if I'm browsing for the font that feels right, and clutter up the list in general. I also am wondering 2) why can't I search in this dock? Am I doing something wrong? The input fields above and below the list appear to not do anything at all, but that can't be the case or they wouldn't be there.

Plz halp thx Smile]]>

I’ve put together what I hope is the definitive reference: every enum available in GIMP 3.0, compiled directly from a live GIMP 3.0.8 instance using a Python-Fu console script. That means the values are guaranteed accurate for that version. And the script is available as a free download so you can regenerate the complete listing for any future GIMP 3 release.

Each enum includes:
  • the Python form you actually use in your plug-ins (e.g. Gimp.LayerMode.NORMAL)
  • the uppercase PDB identifier, most useful when cross-referencing with the C API docs or porting code from GIMP 2.x Script-Fu scripts
  • the raw integer value for legacy Script-Fu work
  • the GEGL nickname for serialisation.
The Gimp.LayerMode table also includes the full GEGL operation string.

Every enum has a plain-English description written specifically for Python and Script-Fu developers.
