Right bounds (rtbd) feature



  • Hey there,

    For a project I'm working on I've come to a situation in which in order to avoid making a lot of kerning pairs I might need to use feature classes in order to add space between them. While reading the specs for OpenType features I've come to these particular ones:

    · Left bounds (lfbd).
    · Right bounds (rtbd).

    The point is that I've never seen these in use or a line of text using them so I don't know exactly how they are supposed to be set. Any help?

    Thanks a lot!

    its been described here https://docs.microsoft.com/en-us/typography/opentype/spec/features_ko#lfbd

    You can use pos in an feature to position a character or a pair (like kerning) or even contextual move characters around.
