Hi all

I am testing Gimp 2.9 and i have some doubts:

I understand that filters that have one G are ported to GELG
But what is the difference between "Tools - GELG Operations" and filters that have a G?
Gelg Operations are filters ported to GELG that use OpenCL and others do not?
In the "Colors" menu nothing has G, this mean that neither Levels, Curves, Posterize, Threshold, etc are ported to GELG?

Thanks

The name of the library is gegl :-)
The filters are ported to a gegl operation. Gimp 2.9 can make use of the operations in a way that gimp 2.8 cannot.
But for testing, gegl operations can be tested with "Tools-Gegl Operations".
In gimp 2.9, the gegl operations will be adapted to the gimp code, and the corresponding operation will be blacklistet in
the "tools-Gegl Operations", so the operation will not show in the list.
If there is a code for OpenCL and it is activated, gegl can use the OpenCL code.
What is the difference? Gegl operations need parameters, as the active layer or more layers or whatever.
The operations in "Tools-Gegl Operations" uses just the active layer, so some of the operations are not usable.
Gimp 2.9 will base on gegl, so almost everything is ported to gegl. With Gegl, it is possible to use a higher colordepth
that gimp/pixbuf/gdk/gtk. Levels, curves, etc. are used now on gegl buffers, instead of pix buffers, so there is no need to
make them with a G in front.

Remember: Filters are realized as plug-ins (Also Gegl filters), tools and basic graphic operations (colors, levels, etc) are not plug-ins, but part of the program.

Sorry for the mistake -->   GEGL not Gelg

I understand then that for example the Levels of "GEGL Operations" will become the levels of "Menu Color" when it is completely ready
GEGL operations is as a sort of test before proceeding to the right place?

K1TesseraEna, according to this list appears that some filters already using OpenCL, although this may not yet enabled in the code, do not know

Thanks for your answers

OK, thanks for the info
