Description
Description
switching on opentype SVG color font support in chromium
Who's implementing?
- I'm willing to implement this feature myself
The problem
Upstream issue:
https://bugs.chromium.org/p/chromium/issues/detail?id=306078
although it was marked as "WONT FIX" in 2021, Google engineers actually did most of the work in 2022, but left it disabled. Attached are two patches which switches opentype SVG support on. Tested against patched QT 6.7.0 Beta 1 (which includes a modified/slimmed down chromium m118).
Possible solutions
The patches and the CI to build the fedora RPMS are on https://github.com/HinTak/Qt6WE-OT-SVG/ and tested with PyQt6 in https://github.com/HinTak/minimal-web-browser s/
. In a nutshell, try visiting either https://yoksel.github.io/color-fonts-demo/ or https://pixelambacht.nl/chromacheck/ before and after applying the patches.
They are discussed in https://github.com/HinTak/chromium-mod-CI .
Alternatives
No response
Additional context
webkit-based browsers and firefox support opentype-svg for some years, and for almost a decade now.
I am aware that the patches need to be adjusted/modified beyond m121/m122 (they are more or less the same in between m112 to m120).
