Choosing Subtable formats
Posted: Tue Oct 17, 2017 11:15 pm
Hi!
When I create a Chaining Context, the resulting lookup table always appears to be using ChainContextSubstFormat3. Is there a way for users to pick an alternative format like ChainContextSubstFormat1 or ChainContextSubstFormat2 (that is provided it is possible)?
Does Font Creator support data contained in GDEF tables which ChainContextSubstFormat2 uses?
I realize that for most use case, having the ability to select the encoding of these tables might not be needed / relevant. However, in my case I am designing a text layout engine where I use Font Creator Pro to create font files for testing these different formats to make sure my tool reads and processes them correctly.
