Hi Hans,
Yes, sorry about the error :).
Thanks for the explanation, will use lmtx for that, though probably best just using another font (some mentioned on the list https://www.mail-archive.com/ntg-context@ntg.nl/msg92800.html https://www.mail-archive.com/ntg-context@ntg.nl/msg92800.html and https://mailman.ntg.nl/pipermail/ntg-context/2020/098136.html https://mailman.ntg.nl/pipermail/ntg-context/2020/098136.html) or svg or metapost as I do not need it in colour.
I thought it would be easier via fonts but backtracking on the idea now and maybe using something like this instead: https://thenounproject.com/term/handshake/153516/ https://thenounproject.com/term/handshake/153516/. btw, some emoji fonts have both bw outlines and bitmap color, some use
I spend quite a bit of time looking into this (it's already a while ago when I implemented all this and color stuff in otf is a bit of a mess and evolving, so in retrospect it's probably better to wait a few years to see how that works out; the same for variable fonts ... hadr to deal with when there are not many fonts and fuzzy specs.) Anyway, the problem is this: these png emoji are using palettes + masks and that combinaiton gives: - with gm (gs) : white background - with mutool : black background - with luatex : a mess - with lmtx : what we want now, testing all this takes a lot of time in mkiv because building the cache file takes time, so it's one of these moments i wonder if a modern machine would do better than my old but reliable machine. The outcome is that in mkiv one can do this: \enabledirectives[backend.otfpng.method=lmtx] % the real deal, slow \enabledirectives[backend.otfpng.method=mutool] % black bg \enabledirectives[backend.otfpng.method=gm] % white bg, default So, when you have a fast machine or a coffe break, you can use the lmtx method (can be configures in cont-loc.mkiv). As manetioned, in lmtx it is done differently so no penalties there. png (bloated), and microsoft fonts have efficient outline color (nice mechanism).
