Thanks Alex for explanation.

I've written a minimally functional gegl ui that works in Laidout:

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

It can also import SVG filters

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

You are my hero :-D.

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.

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).

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.

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.

[Gimp-developer] GEGL

2018-03-13 Thread Michal Vašut
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
