Re: [Gimp-developer] bug with Overlay

Hi! Thanks for answering.

 I agreed about interpolation. But as I said in my video 3dCoat is fully compatible with PHOTOSHOP. So, Overlay method works exactly as in photoshop, because it's a standard of CG industry.
 You already did this with GEGK too. But I cannot save Gegl image. :(
I cannot merge layers with Gegl interpolation and I cannot save to PNG/JPG with Gegl interpolation. This is the main problem.

I did another comparison with photoshop and Gimp:

I found a bug with Overlay and Gegl:

I don't think it's a bug.
As far as I can tell, that's because the 3D program where you created your multilayered file does layer blending in linear space and GIMP with GEGL off does it in gamma-corrected space.
When "use GEGL" is selected, GIMP does the layer blending in linear space too, then you get similar results in both applications.
Some blending modes like overlay look very different in linear and non-linear space.
I'm not 100% sure, but it looks exactly like that.
