Re: [Gimp-developer] Multiply blend mode in GIMP

[Calculemus <calculemus1988 gmail com>]

Another confusing blend mode is Overlay.

I have found 4 sources that have one definition for Overlay,
and GIMP uses another one, I am confused.

1. The official Adobe reference version 1.7 chapter 7.2.4
2. http://www.gegl.org/operations.html#op_svg:overlay
3. https://dvcs.w3.org/hg/FXTF/rawfile/tip/compositing/index.html#blending
4. http://www.pegtop.net/delphi/articles/blendmodes/overlay.htm

Thanks
