Description Akira TAGOH 2019-03-20 06:29:47 UTC

Description of problem:
LibreOffice doesn't support Variable fonts.

Version-Release number of selected component (if applicable):
6.2.1.2-1.fc30

How reproducible:
always

Steps to Reproduce:
1.install google-noto-sans-vf-fonts say (make sure if you don't have google-noto-sans-fonts installed because both has same family name)
2.open LO and select Noto Sans
3.type something with bold decoration.

Actual results:
No decorated as bold

Expected results:
should be decorated as bold

Additional info:
There are "variable" property in fontconfig to see if a face is capable for VF and "fontvariations" to see what parameters has variations. those two properties are set only for entire space. but for an instance. an instance looks similar like standalone typefaces.

Is there something already existing (using harfbuzz or whatever) where this is already working for comparison ?

Comment 2 Akira TAGOH 2019-03-20 09:11:28 UTC

Pango supports it.

Comment 3 Caolan McNamara 2019-03-20 15:09:58 UTC

For the basic cases of the named variants this should have worked out of the box, but apparently we've outsmarted ourselves and overwritten FC_INDEX in out fontconfig pattern which is getting used to transport that info around.

Got something working here
