Combine glyphs on export

[drawcard]

Hello, I’m looking for a way via custom parameters & filters, to programatically combine certain glyphs together in order to make a trial font.

For example, if I had a period & comma glyph, and I also had a hidden _demo glyph, I could stamp the _demo on top of the regular glyphs like so, on export:

Thanks for your help!

You could write a simple filter plugin, or I guess you could use LayerGeek:

or instead of A, use _demoGlyph or whatever the name of your glyph is: components.append(GSComponent('_demoGlyph')), and copy that filter parameter, and paste it into your instance custom parameters.
