OpenType SVG fonts open slowly in Fedora 39 Linux
epico opened this issue · comments
I downloaded the Noto Color Emoji fonts from Google website.
URL: https://fonts.google.com/noto/specimen/Noto+Color+Emoji?query=emoji
I check this font with ttx, it contains the SVG table inside the font.
SVG 0x8EA0F1D5 19252109 4763880
It seems this is an OpenType SVG font.
It takes several minutes to open this font with gnome-font-viewer.
I rebuilt ftview with librsvg, ftview also takes several minutes to open this font.
Why does it take several minutes to open the OpenType SVG font?
Well, quite simply because it's huge and the font viewer is probably trying to load all the thousands of emoji glyphs all at once. I'm not sure there is much we can do.
Ideally use the COLRv1 font (present in this repo under /fonts, see https://developer.chrome.com/blog/colrv1-fonts for context). That require that gnome-font-viewer and ftview support COLRv1; I'm not sure whether they do.
I don't think there is anything to be changed in this repo so closing.
