I have a script that calculates and sets Alignment Zones based on selected Glyphs.
For the denominators it automatically adds a filter.
Before we have cff2 and I have a zone with a scope, will this zone be used for autohinting (In this case my dnom top zone)?
If the zones with a filter get used, I have an overlap of the baseline and dnom bottom zone. Will this create problems?
Should I disable the dnom bottom calculation and the dnom top filter?
IIf the top zone with the filter will not be used, wouldn’t that mean I should disable the filter? So that the zone gets used?
You only can have a very limited number of zones (I don’t remember 100% but something like 7 top and 5 bottom zones). So you run out of zones very quickly. And they are not allowed to touch.
12 to be precise.
Yes, that’s why I was asking about the filters …
So the best way would be: don’t have a bottom zone for dnom and don’t set a filter for the dnom top zone. Thanks for the clarification.
You can add the metrics with a filter to help with the design. And when we add cff2 support they are put to good use.
