Lumi-o is a Linux-only, dedicated layered raster painting application focused on stability, responsiveness, and a streamlined illustration workflow.

Built on GIMP’s core architecture, it prioritises painting performance, reliable autosaving, rolling incremental saves, and support for massive canvases through lazy loading.
Wacom tablet support has been extensively tested for smooth, responsive input.

Developed on Debian 13 with the Cinnamon desktop environment.

After a long period of development and testing, Lumi-o is now approaching its first beta release. Most major design and architectural decisions are already in place, with the remaining work focused mainly on polishing and bug fixing. Any testing and feedback is greatly appreciated. An AppImage build is available alongside the full source code.

   

After downloading and installing a Color Theme, Hypergraphite, which works OK. I found it does not display in the Opening Screen in Personalize.
It does appear in Edit> Preferences> Theme along with Default and System, and they all work OK.
Does anybody know if this is a bug or perhaps it has not been coded in, to update in the Welcome opening.

Hi,
I use Gimp to every week to manipulate a batch of photos (50 to 150), with "Batch Image Manipulation plugin" the primarily to reduce the size and convert them to jpg.

Recently, this batch process took the initiative to rotate the photos... ! From vertial to portrait.
And I don't know why.

Here's a screenshot  of the plugin with two manipulation (resize and change format/compression, but in french)





Maybe you have an answer ?
Thx

I'm fairly new to GIMP, although I'm no stranger to audio, video, and some image editing software, to include the now defunct Photoshop CS3. I'm reasonably confident I can dance through various options until I get my desired results, but today I'm stumped.

I'm trying to find a Windows x64 repository for a GIMP 3.2 Resynthesizer plugin, but I keep getting directed to v2.x and 3.0 plugins, many of which are python-based script. I understand GIMP 3.2.x no longer supports python-based script. I'm registered with GitHub for some of the audio/video editing and ripping software I use, and I'm not having any luck there, either, since most of the code within GitHub's repositories are Linux-based.

Can somebody point me in the right direction? The basic GIMP 3.2.4 plugins are fine for what they are, but I know firsthand how powerful tools can be when they are readily at hand. The tools I've read about that are contained in the resynthesizer plugin are some tools I'd like really to try.

Thanks!

Hello, I went to bed last night satisfied with a finished product. When I woke up this morning to make a few changes the project was "locked". I could not select any of the objects in the image. Initially, I thought only one project was affected. Not so. ALL of my projects are now locked for editing. I've uninstalled and re-installed GIMP 3.2.4 but to no avail. What could possibly cause this. I've also rebooted the computer several times. I'm at a total loss.

Thanks in advance for any help ...

Merci pour votre aide

I'm sure this has been answered more than once before, but I can not figure out how to use shortcuts when the text tool is active. I find myself often in situations in which I need to adjust text, move it, return to text, etc. T is easy for text, but as one who uses shortcuts as often as possible, I find it a nuisance to have to reach for the mouse to click on the Move tool. I figured Alt, Ctrl, or some combination with Shift would make the switch, but it doesn't seem to.

Thanks.

I have created a book cover for someone, for Amazon print-on-demand, which measures spine width by paper thickness x pages. I have made an estimate for final page number and sized the back/spine/front cover image accordingly. If the spine width should need to be increased, and thus the entire background layer/canvas, what's the best way to do this? 

I tried enlarging the canvas, which left a transparent sliver on one edge. I tried filling the transparent area with the background layer color but nothing happened. 

So, first, I don't know how to get the added real estate in the background layer, and second. I really would like to avoid having to move each layer over a tiny a mount to recenter.

Thank you!

In GIMP prior to 3.2.X I often used many of Ofnut's scripts, but many do not work in 3.2.2+.  I recently updated dial marks to work with GIMP 3.2.X based off the original ofn-dial-marks.py.  I would like permission to post my updated dial-marks heavily based on ofn-dial-mark.py, for everyone to enjoy. 

If it is not allowed, I understand.  
I do plan on updating other Ofnut's scripts that I use if they do not seem to work with GIMP 3.2.X. I will post them here as well, if it is allowed.

Thank you.

Hello, 

first time posting here. I'm a casual GIMP user, mainly using it for creating Sim Racing Liveries. 

I recently experience an error message when exporting to DDS format using BC3/DXT5 or BC7. I'm on GIMP 3.2.4 using Linux, same happens on 3.2.2. Only 3.0.8 seems to work for BC3/DXT5 (BC7 is ot supported here). 

I tested also on my Windows 11 Laptop with Version 3.2.4, also doesn't work here. It also seems not to be a picture issues. Old pictures where the export to BC3/DXT5 worked before, will fail during export on 3.2.4 too. 

Any ideas based on the attached error message? Any hints are welcome.
