Just want to back a request which has already been done in the pas I think : I would find it really useful if metrics keys could reference other glyphs at a specific height. This could be particularly useful for glyphs with ascenders / descenders. Thanks!
We are discussing it for a future version. Cannot promise anything though. What should happen if there is nothing at that height in the referenced glyph?
I think it should give you warning and do nothing else.
That seems overly complicated to me. I would suggest the same behaviour as when a metric key references an empty glyph : zero.
i dont get it, could u elaborate when a need for this occurs?
or when and how this is helping?
i am unaware of any relevance of metric keys in relation to height, only width.
This would measure the side-bearing directly at the stem and different serifs or overhanging accents would not disturb the values.
Or you could refer to the end of f crossbar and ignore the shape of its ascender. You could sync t and f that way.
I was also wondering whether it would be interesting, instead of using values, to have references to metrics : desc., baseline, mid x-height, x-height, asc., etc. That might make the syntax a bit complicated, but it would make the keys more portable from project to project… Just a thought!
I keep that in mind.
oh i see, yes interesting, in that case i was thinking something similar the other day
more along the line of an offset of some kind/resetting the origin. but defining a height potentially one of the vmetrics would make it more robust… i like it
