Group-group-specific kerning rules

Post by SCarewe »

Hello. I have come across a question that doesn't seem immediately resolvable to me with Kern On. For math operators, I want to set them to No Kerning among each other, so that no math operators receive kerning against other math operators. But I still want things like 7+7 to be kerned. So, ideally, for math operators, I would like to set a group-specific spacing rule of No Kerning against other math operators, but normal kerning against numbers.

Is this possible? Thanks a lot!

Agreed, sometimes it would be handy to specify things such as no kerning between certain groups of glyphs. Similarly, you may want special spacing between certain groups but not others. Right now, Kern On allows to have an individual special spacing value within one group, i.e. if both glyphs are from that group. For example, I want the superiors to have generous special spacing against letters but not within themselves. This is something that’s detected automatically of you set the models.

Maybe I should add a proper “special spacing manager” dialogue that allows to set these things in detail?

For now, a work-around for you would be to generate all math-math pairs via a simple script, and then set these pairs to independent zero pairs. Not an elegant solution, though, I have to admit.

Hello, thanks a lot for your thoughts. A special spacing manager would be great for (optional) granular control. The automatic detection works very well so far, but for cases like the one outlined above, more specific controls would be very useful.

I will try your suggestion, for the time being, it's a decent, simple solution.

Thank you!
