Hi all,

I have an RGBA image that is all black, with the alpha channel defining where it's black and where it's transparent.
I need to convert this to an RGB greyscale image, i.e. one that will draw the same as the RGBA image given a pure-white background.
How do I do that? I am a bit lost in the multitude of operations that Krita offers.

Make a fully white layer, put it underneath the black + transparent layer, save as png?

Thanks, that worked.
No need to save as PNG actually, I could right-click the image layer and "merge with layer underneath".
