New G'MIC-Qt filter! ▶️ Filter "Rendering / Variable-Density Hilbert Curve" turns any image into a single winding line, with local density following luminance, the effect described in our latest G'MIC Adventure #7, now just a click away, with adjustable parameters. #GMIC #GIMP #Krita #PaintNET

New G'MIC Adventure #7! 🐉 We build a variable-density Hilbert curve that reproduces an image as a single winding line, with local density following image luminance. Follow the full thought process — including the bugs introduced along the way 😅 ▶️ discuss.pixls.us/t/gmic-adven... #CreativeCoding

A little preview of "arrange", a new G'MIC command currently in development. It lets you combine images into custom layouts (grids, symmetries, rotations...). While testing it, we ended up with these lovely little creatures 👹 ▶️ discuss.pixls.us/t/new-comman...

📖 Our yearly G'MIC recap is out! Beyond the 4.0 release, this article dives into a year of work behind the scenes: new G'MIC-Qt filters, the variational color transfer algorithm, creative coding scripts & more. Don't miss it! 🤩 EN: gmic.eu/gmic40/ FR: linuxfr.org/news/g-mic-4... #GMIC #OpenSource

G'MIC 4.0: Squaring the Pixel, Easier Than Ever!

🎉 G'MIC 4.0.0 is here — a major release focused on stability. It also opens a new chapter: fewer releases ahead, with more focus on framework robustness & performance rather than big changes. The core is mature — now we polish it. Developed @ GREYC lab (CNRS/ENSICAEN/UniCaen) ▶️ gmic.eu @cnrs.fr

🚀 Coming soon in G'MIC 4.0: New filter ▶️ Rendering / Pixel Stretch ◀️ ! Add colorful streaks to your images, like this! 🌈 (New G'MIC release scheduled on Wednesday, July 1). #GMIC #ImageProcessing #GIMP #Krita #plugin

Variations on a theme of 'tuatara' (made with GMIC / @gmic-eu.bsky.social) #digital #art

🎨 New filter in upcoming GMIC 4.0: ▶️ Colors / Transfer Colors [Multi]!◀️ Transfer the colors of a style image onto a content image, using our new variational algorithm. And even guide the mapping manually when needed. Fast, no ML, open-source! 🔗 discuss.pixls.us/t/new-filter... #GREYC #CNRS

After years of frequent releases and constant new features, it's time for G'MIC to take a breath. I've just kicked off work on G'MIC ▶️ 4.0.0 ◀️ 🎉 . The 4.x branch will be all about stability and performance. Fewer releases, but rock-solid ones. Excited to see where this new chapter leads!

Today, we've got an interesting message from D. Strupl: "I’ve been working on a Rust-based macOS bridge/plugin for using G’MIC from Affinity Photo 2 and v3: github.com/dstrupl/gmic... I’m looking for feedback from G’MIC/Affinity users (...)" Anyone willing to help? 🤩

What if you used the wave equation… to create nice image filters? 🌊 New episode #6 of ▶️ GMIC Adventures ◀️ explores how to go from math to animated effects, step by step, with full source code, ending with waves flowing along image contours! 😅 👉 discuss.pixls.us/t/gmic-adven... #creativecoding

Just tested G'MIC-Qt 3.7.6 on Mac via MacPorts: noticeable filter speed improvements observed compared to previous version. 🚀 Many thanks to the MacPorts maintainers for keeping the gmic-gimp port up to date so fast! 🙏 #GMIC #MacPorts ▶️ ports.macports.org/port/gmic-gi...

✨ G'MIC ▶️ 3.7.6◀️ just dropped! Under the hood: a faster math expression evaluator + cleaner Makefile & CMakeLists.txt. A minor release with meaningful improvements! #GREYC #CNRS #ENSICAEN #UNICAEN #GMIC #OpenSource #GIMP #Krita

🥳 Exciting news! G'MIC-Qt ships built-in with latest release of @PhotoFlareIO v1.7.0 🖼️. That's more than 650+ open-source filters (film emulation, inpainting, artistic effects…) available in one click for PhotoFlare users. Open-source collaboration at its finest 🥰 ▶️ photoflare.io/what-gmic-ad...

🎨 G'MIC 3.7.5 is out! Our open-source image processing framework (CLI, library & G'MIC-Qt plugins) just got a fresh update with fixes & improvements across the board. Thanks to all contributors! 🙏 👉 gmic.eu

🚀 We have a new G’MIC-powered Demo Kiosk: The SteamFace Machine! Check out our physical demo station featuring our neural-network based facial feature detection & analysis. Still WIP but looks cool! 👉 Video demo attached—try it live at our next events! 🤩 #GREYC #CNRS #ENSICAEN #UNICAEN

🚀 We released the source code of our interactive G'MIC demos: Face Analysis, Image Style Transfer & Real-Time Face Warping—all under CeCILL license. 🔬 Developed at GREYC (CNRS/ENSICAEN/Unicaen) in support of France’s Open Science Plan. 👉 github.com/GreycLab/gmic-interactive-demos #GMIC #OpenScience

⚙️ I've started a new G’MIC-powered side project! Building a small real-time facial feature detection demo… in full steampunk style 🛠️✨ Face detection is already working 🎯 Now aiming to have it ready for the next science festival in Caen! Stay tuned 🚀 #GMIC #GREYC #CNRS #ENSICAEN #UNICAEN

Someone made a nice video about our G'MIC-Qt plug-in for Affinity! 🤩 ▶️ youtu.be/iD_lD_azvFA?...

The biggest plug-in for Affinity! (V1-V3)

Our G'MIC Online web service, maintained by GREYC's DDA team, has been updated with the latest version of G'MIC, 3.7.2 😍 Feel free to try it out to apply filters to your images directly from a web browser! 🎨 ▶️ gmicol.greyc.fr #GMIC #GREYC #CNRS #ENSICAEN #UNICAEN

🚀 G’MIC ▶️ v.3.7.1 ◀️ is out! This minor update brings a few new filters, bug fixes, performance improvements, and enhancements across the framework. So happy to see how far the project has come since 2008! We’re now taking a short break to recharge, and we’ll be back even more motivated 🔋 Enjoy!

Surprisingly, my latest filter tends to mess up tigers’ hair! I’d better avoid using it on myself! 😄 🐯 🪮

New filter ▶️ Artistic → Marker Drawing ◀️ now available for our G'MIC-Qt plug-in, version 3.7.0! A very entertaining filter, generatesresults that can vary greatly depending on how you adjust the settings. Enjoy! 🥂 #GMIC #GREYC #Filter #ImageProcessing

Creative Update 🎨 Work in progress on my G'MIC experiment that try to simulate marker drawing… I progress slowly but nicely, and I must say, the results are looking pretty cool to me already! Still tweaking the behavior of strokes and ink diffusion, but it's getting there 🙂 Stay tuned!

Tonight, I'm experimenting with a G'MIC script, trying to simulate a kind of Marker Sketch. Not sure we'll come up with anything conclusive, but it's still pretty fun! #GMIC #GenerativeArt #CreativeCoding

Creative Tuesday 🎨 A small animation inspired by the Diffusion-Limited Aggregation (DLA) process, revisited and generated with a short G'MIC script. Mesmerizing organic growth, emerging from simple rules! ▶️ Source code: pastebin.com/TAMQRehK #Gmic #CreativeCoding #GenerativeArt #AlgorithmicArt

Creative Saturday 🎨 I played with the Hilbert curve a bit today and made this little animation, with a G'MIC script. Looks like a twisted Star Wars lightsaber! ▶️ Source code: pastebin.com/64syuj3D ▶️ Hilbert Curve: en.wikipedia.org/wiki/Hilbert...

I've always been told, “Never release anything on a Friday!” — let alone Friday the 13th! 😈 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! ▶️ Changelog: discuss.pixls.us/t/release-of...
