Really nice ! Where's the associated speedpainting video ? 😅

I've always been told, “Never release anything on a Friday!” — let alone Friday the 13th! 😈
So today feels like the perfect time to do it anyway 😅
I'm then happy to announce the release of a major new version of G'MIC: ▶️ 3.7.0 ◀️ !
Lots of improvements, new features, and refinements under the hood.
Enjoy!

🚀 New Release: G’MIC-GEGL v0.1.0! 🎉
We’re excited to share that the first public release of G’MIC-GEGL (v0.1.0) is available!
This experimental project brings over 1,500 G’MIC commands directly into the GEGL framework as native operations, meaning G’MIC filters can now be used inside any GEGL-based app (including #GIMP of course!).
Kudos to Łukasz Grabski, developer of RasterFlow who made it possible!

Apparently, G'MIC is now available on the Snap Store! I'm not a big fan of Snap, but if it helps users install G'MIC more easily, that’s definitely great news! 👍

Starting the morning by doing a bit of coding for work, and realizing it has potential for generative art. Always a nice feeling! And another gif anim that loops perfectly 🤩

Peut-être l'occasion de te réinviter en Normandie pour profiter de la fraicheur ? 😋 On y trouve du réconfort !

New filter "Rendering / Speech Bubble" is now available in our G'MIC-Qt plug-in!
This filter lets you create comic bubbles in different shapes.
It wasn't so easy to make, but there was a lot of fun math involved!
Enjoy! 👍

12 days ago we released our latest stable version (G'MIC v.3.5.3).
Since then, more than 25k downloads have been served from our website (more than 2k downloads/day). For a modest project like ours, this is incredible!
The release of @npub1jxd…txs3 3.0.0 also helped a lot 😉.
A big thank to all the users who think our G'MIC-Qt plug-in is not that bad and who are promoting it all over the Internet! 🍻 😘

Does not work for me! Should I fill an issue?
No interest here... If only it were something she could eat!

That's fine ! I'll write you ASAP.
Yes, the downscale is simulated during the training. For the images, the more is probably the best :) In the training data set I used here (DIV2K), there are 800 images, but I guess a hundred would be already enough (yes, that's already a lot...).
We can try with less anyway, and see what happens.
We could also try not only with lineart, but also flat-colorized images, to have a bigger dataset.

Let me know David, I've tested it a bit with linearts and found it works quite well. But we could even think about training a specific CNN model just from lineart images (I guess you could provide me with a cool dataset, right ? 😉). I'm open to any ideas to improve it for very specific uses. Cheers.

New filter **Repair / Upscale [CNN2x]** in our G'MIC-Qt plug-in!
This one uses a small convolutional neural network (CNN) to double the image size, while trying to keep contours as sharp as possible. Another cool tool in the arsenal of G'MIC filters!

Today, we release G'MIC version ▶️3.4.3◀️.
With the passing of my friend Sébastien, this may be one of the last releases for a long time.
I'll try to keep up the maintenance and debugging as much as I can anyway. If you'd like to help keep the project alive, you're welcome! 🙏
