How do you make an inline font?


Is it possible to easily create an inline version of. a typeface with Glyphs? I tried using offset path with the stroke option, but couldn’t get the result I wanted. Here is what I’m wanting to do:

Is the best option just to copy my glyphs into Illustrator, create the inline there, then copy the glyph back into Glyphs?


How do you create an inline in AI?

The problem is a logical one. There is never a unique solution for an inline, and a lot of guesswork has to be done, especially where strokes meet (e.g. in the middle of the M). Therefore it cannot be automated.

What you can do, however is get the middle of two (compatible) lines through interpolation:

  1. On either end of the stroke, select the two end points and Opt-Delete them. This should break the path into two paths.
  2. Double click one of the two paths, so it gets selected entirely.
  3. Right-click and select Reverse Selected Contours from the context menu.
  4. Choose Paths > Selection to Background (Cmd-J).
  5. Press the Delete key to remove the selected path.
  6. Filter > Transformations > Background with 50%, confirm.

Now you have the middle line. Of course, this only works if both halves of the path are actually point-compatible, otherwise step 6 does not work.


Thanks for the reply, I’ll try that out along with Illustrator to see what is best. Either way, there will be some adjusting for the complex shapes. I want to at least get the inline of the curves, since that is hard to do manually.

To do inlines in Illustrator, I think using Blend is one of the best ways. Not perfect, and you might have to fiddle with things. There are a lot of steps, but it’s worth it for me to get those curves exactly right.

and here is a pdf that explains it well


That is exactly what I just described.


I’ve made a script that does the interpolation for me. You need to select a stroke (pairs of nodes), then run it.Used in Wolpe Fanfare Inline.

It’s not very smart at finding pair nodes and you need to fiddle around with start nodes sometimes, so not quite sharable yet (about 90% accurate though). But watch this space!


Looks wonderful! I’d love to try it.


Mekkablue, your steps worked great, thank you.

Is there any sort of plugin that could automate part or all of this process? I’m thinking something like Photoshop’s Actions.

@Tosche , is your plugin ready to be released yet? :slight_smile:


@mekkablue: What do you suggest for creating an inline for continuous shapes like the O?


The process above would work for that as well, given inner and outer paths are compatible.


Thank you @mekkablue. I just needed to correct path direction and tidy up paths.


Hi Toshi
Is that script shareable now?


Unfortunately not. It’s a pretty simple script though, mine is not even 100 lines.
