How to remove black-and-white emojis
Closed this issue · 11 comments
I'm using Android 13 and I've applied the font for emojis. In some specific Apps, it displays both black-and-white and color emoji. For example, I type star⭐ and a kissing face😘, and it shows a color star and a black-and-white kissing face. I want to remove black-and-white emojis, and how can I do that? Or is there a solution to make the color emoji superior to black-and-white one?
send screenshot!?
it's might because a13 has vector system emojis and i think that counter-changing from colrv1 to bitmap or bitmap to colrv1 would do such, as yours.
Above are screenshots. And what is 'colrv1 to bitmap or bitmap to colrv1' ? I don't know much about that... Actually I'm new to font files...
absolutely that's bitmap font, a13 has colrv1 ttf and they're vector.
- in vectors everything is assigned in the size & the color by the strings of codes. as size changes so the pixels that would change the color, it's all calculated as drawables and the change in size doesn't affect the quality, because colors' tone and everything is more like re-drawn but all that takes a lot of cpu processing too.
a13 processes that, because any os would've the access and info about the display, they can process the vector values without giving access to like other software to do so! that's why previous android versions won't be able to display svg or colrv1 images or glyphs, unless apps use androidx vector drawable support. but the apsp won't process the vectors though.
vector ttf files need processing and the os must support vectors, or any other software must be able to.
- bitmap ttf has the number pixels' value and the color.
size won't the color value it'd be the same and quality is bad for low res-displays, as the value of pixels actually pixelate them. bigger size of a glyph shows the real quality of image.
they don't need processing as they are just shown as images or texts.
tl;dr
ttf files are actually vector images for outlines (lines or curves) for texts. and in bitmap font glyphs are array of the pixels.
in your case i think os is taking some emojis as vector and they're black. the colored emojis must be bitmap?!
i don't that applecoloremojis.ttf contain vector!?
Well... That's really confusing. Will you help to check the font file? Such display looks really bad...
is it only in the app?
Thanks @idontveapc for the help!
@ACT-02: As @idontveapc has mentioned, it will probably easier to try with other projects targeted specifically at Android (a quick GitHub search should do). Even though Android is Linux-based, it's likely that font management differs (e.g., fonts installed in different directories).
If you still want to continue with these ones, you can try following the instructions at "Can I install the emoji on Android?". (This other repo is for WhatsApp emoji, but the build process is analogous to this one).
okay, ive got what the problem is...
don't use this font from apple(it's named blah-blah but i expect it's sf pro compact bold with emojis, usually they're in private area-b but not for this one). or change your system font xml making it only for vs-15 fallback. because theyre bnw and bnw emojis are showed (for select emojis) when vs-15 unicode is used with an emoji. ...like
it's maybe otf so it's vector i think, that is why it's bnw. may on adobe software show them coloured, or may it's just bnw.
*forgot to add...
vs = variation selector.
the 15 for a bnw (black and/or white) glyph and the 16 for a colour glyph (png or vector).
again you are getting the problem because of the font and it's showing the vs-15 kinda glyph instead the color glyph (vs-16) from the font by sameulngs. (may be because the font you're using is the main font and here the color font is working as the fallback one, which is weird as bnw glyph won't be showed by default. and on android NotoSansSymbols-subsetted or NotoSansSymbols-subsetted2 has the vs-15 version of these some emojis).
you should close this issue now...
Thanks a lot! I've been long out of GItHub. Now I am here to close this issue.
