Anchors



  • This might be a stupid question but I just don’t get the way anchors work in RoboFont. I’m new to font editing, I’ve never used FontLab but I’ve seen tutorials about how anchors work there. I understand the purpose of anchors and I understand how FontLab is dealing with it but in RoboFont things seem to work differently and I can’t figure out how.

    I’d like to use them to position diacritics. So I placed one anchor in the base glyph a and named it top and another in the accent glyph ¨ named _top. Then I built the ä by adding a and ¨ as components to the empty ä glyph. This is kind of the FontLab way and it doesn’t work.

    After trying other combinations without success and failing in research on the web on this specific topic here I am.

    Is there an out-of-the-box-behaviour for anchors or are they supposed to be accessed by scripts in order to use them?

    Thanks for your help

    RoboFont has not yet support natively for placing components with anchor support.

    You can use font.generateGlyph(...) to compile glyph with anchor placement.

    font = CurrentFont()
    
    font.generateGlyph("adieresis")
    

    good luck

    there is no native support to build accents 'magically'

    you can still use robofab as the example above

    or write a small glyph construction string when adding a glyph

    adieresis=a+dieresis@top

    see Adding and removing glyphs



  • It's 2019 and i still don't get how anchors work in RoboFont (v. 1.8.4). Anchors i create, base glyphs and diacritics, seemingly don't link to each other, so i just add new glyphs using the aring=a+ring kind of syntax than move the diacritic manually to place it right. Can't find the answer on how to link them anywhere, don't really know what terms i should be looking for. The documentation provided by Robofont website is not very helpful for total beginners like me...

    hi @jhera,

    there are multiple ways to build accented glyphs in RoboFont. these are described here: Building accented glyphs

    have you tried using the Glyph Construction extension?

    in 2019 you don’t really need anchors to position diacritics anymore :) you can still use them (with or without underscore), but you can also use guidelines, variables, vertical metrics attributes, reference positions, etc. have a look at the docs & give it a try!
