good you found it! kerning values has to be set very precise. Did the extension DesignSpaceEditor show this kern error in the report? good luck!

[[qanda:topic_unsolved]] contextual kerning in RB, MM?

@frederik I dream of the day someone would convert fontTools feature ast objects to json and we won't use fea file anymore.

[[qanda:topic_unsolved]] Fontparts, Kerning groups and performance.

Hi @frederik It just never ends, no tracebacks. If I don’t manage to solve it with @gferreira tip I will try to prepare a dummy ufo and post it here. Thank you both!

[[qanda:topic_solved]] GlyphConstruction as script: x = a&\b gives traceback if no kerning pair is present

frederik — Wed, 18 Mar 2020 17:23:51 GMT

should be fixed here: https://github.com/typemytype/GlyphConstruction/commit/01c7c9362561822a68073305c69c9fbc054ddf13 Getting kerning is advised to use font.kerning.get(pair) where it does not fail. This is similar to a normal dict. Or you can also check first if pair in font.kerning: ... thanks!

[[qanda:topic_solved]] Kerning offset overflow

ArrowType — Thu, 12 Jan 2023 03:33:46 GMT

Thanks Arnaud! To add to this, I had some difficulty finding where in MM to actually do this, so... I found the option under "Batch Export" in the MM menu. I simply exported it into the font (features), and now makeOTF works to generate fonts directly!

[[qanda:topic_solved]] Copying uppercase to lowercase (including kerning), and auto-add unicodes

StephenNixon — Sat, 02 Mar 2019 15:23:09 GMT

@tal said in Copying uppercase to lowercase (including kerning), and auto-add unicodes: Here's a little demo script that will copy kerning. Hmm, at least initially, when run, that causes an error: File "lib/fontObjects/doodleKerning.pyc", line 13, in _set_dirty mm4.MetricsMachineError: Glyph a is in more than one side 1 group. For now, I'll do some (partially) manual things in MetricsMachine to sort out kerning. I'll loop back with a suggested fix if I can loop back and figure something out!

[[qanda:topic_solved]] Best way to remove glyph from RFont?

ArrowType — Wed, 15 Dec 2021 15:46:20 GMT

As a belated update, I found that the script above didn’t handle Template Glyphs well. It would remove all template glyphs from the font. This current version of the script handles template glyphs: https://gist.github.com/arrowtype/9ef6ce07233af2d80bc0bfb4290d642c

Certain Kerning groups not exporting

frederik — Mon, 16 Nov 2015 10:26:12 GMT

Hi Andrew you added those kerning values inside RoboFont, with the Kern Center? You created the groups? I cannot reproduce this issue, could you send me a erroneous ufo file?

Remove kerning pair

jo — Tue, 29 Jul 2014 18:46:15 GMT

hello jens, thanks for your help. in fact your example is what "happened" in my case. I did some very quick kerning without groups. Later on I replaced the single letters of the pairs with groups through a script. I also wanted to remove the original pair but the zero value was "overwriting" the group value. so i guess it could work with kerning update etc but the "del" way worked just fine. cheers, jo

Right to Left Kerning

bahman — Wed, 29 May 2013 10:11:29 GMT

I don't know the difference! But in fontlab when I open a font, in the kern feature I can see that LTR kerning is interpreted like this: pos uni0631 uni0628 -225; But RTL kerning is interpreted like this: pos uni0631 uni0628 <-225 0 -225 0>; So I suppose RTL kerning should be implemented with adjustments applied to position of the glyph too, maybe I'm wrong; I'm not a pro. (see AFDKO OpenType Feature File Specification) About the kerning in RoboFont, I think there is a malfunction in the "Right to left" Option in the kerning panel. Here is what I do: I open a font which already has RTL kerning, Robofont interprets kerning correctly. I open the kerning panel and click on a class pair, the kerning shows up but order of glyphs is incorrect, I turn the "Right to Left" option on; Nothing Happens! I turn it off, now order of glyphs becomes right, even so the kerning has been implemented in RTL order.

[[qanda:topic_solved]] Check Kerning

frederik — Fri, 15 Oct 2021 12:29:55 GMT

FYI: fontParts has font.kerning.find(("A", "V")) dont know why its not in the documentation.

Access to kerning classes

frederik — Wed, 30 Jan 2013 11:57:50 GMT

The kerning keys can be either glyph names or group names. If they are group names (starting with an @) you can edit them in with the groups objects f = CurrentFont() f.groups["@MMK_L_f"] Its possible that this group isn't not in your groups but already hard coded into the features. (normally MM is adding those kerning groups also as font.groups items) note: RoboFont does not automatically convert font.groups to feature groups. Use this extension for converting and adding groups to the feature file: http://github.com/typemytype/RoboFontExtensions/tree/master/groups2Features good luck
