GEGL

Is GEGL comparable with Blender's node editor or could it be visualised this way? Or did I miss the concept of it and it's something completely different?

Another one: Does Gimp use GEGL localisations (there are some in GEGL repository), or it's own?

Thanks for answers, Michal

This is a technically incorrect question.

GEGL is an image processing engine. It isn't UI.

It does have a UI which is available optionally, and unlike Blender's node editor, very few people have used it so far. There also was a GSoC project to build a conventional node-based editor with GTK+ UI for GEGL, but it didn't exactly succeed.

or could it be visualised this way?

It can be, see above.

If GEGL operations are translated into your native language, and GIMP uses that language in UI, you will see options of those operations in your native language.

What and where is this ui? I know of imgflo. Is there another? I see a Tool->Gegl Operation in Gimp 2.9, but this seems to be a one time, one operation, irreversible thing, with broader reversible node editing only in the fullness of time, according to Gimp's roadmap.

I've written a minimally functional gegl ui that works in Laidout: https://www.youtube.com/watch?v=GPz3BniLSFw&t=8s

It's very new and not remotely tested enough! It currently can import and export gegl xml files. It can also import SVG filters (still working on export, and mapping to gegl nodes).

My intention is to have this node ui usable, if possible, at least via a plugin to Gimp (for instance). I'm doing a workshop at the upcoming Libre Graphics Meeting about nodes in FOSS to further explore issues involved.

Wow that's exactly what I had in my mind.

I also thought about this. Inkscape has some SVG filter editor, but this looks much better!

You are my hero :-D.
