Implementation of setInstances

[digitaltembo]

Hello! I'm going into this without much knowledge about fonts, but am looking into the possibility of changing a variable font's instances and then exporting it as a new font file. Would anyone have any pointers as to how I would go about doing that? The naive

font.tables['fvar'].instances = [...];
font.download();

didn't work as I had hoped.
(This might also be a question for opentype.js, but I figured if I was able to implement it, it would be a nice addition for this library)

Hi! I am wondering about the same thing - it looks like variableFont.js only allows you to extract variable font information but does not allow you to modify it. Have you made any progress on this?

Following! It would be huge if we could both read and write variable font information. Ideally it could be integrated in OpenType.js - but if I have to put up with two libraries to read and write variable font information from JS, then so be it :-)
