Almost every new major feature people have been asking us for, be it high bit depth support, or full CMYK support, or layer effects, would be impossible without having a robust, capable image processing core.

Øyvind Kolås picked up GEGL in mid-2000s and has been working on it in his spare time ever since. He is the author of 42% of commits in GEGL and 50% of commits in babl (pixel data conversion library).

Thanks to his work, we shall be shipping GIMP 2.10 with 16/32-bit per color channel precision, linear pixel data workflow, and filters that have an on-canvas preview.

But we always need more from both GEGL and babl:

• better performance (always);
• more sophisticated use of GPU;
• support for arbitrary RGB primaries and TRC (think using wide-gamut RGB, like rec2020);
• support for CMYK and spot colors;
• more GIMP filters available as GEGL operations.

And the list go on.

Which is why we ask you to support Øyvind via his Patreon page, so that the development of new features requested by you, our community, could go faster.
