How to process encoded offsets

Question

I am currently greatly expanding the OpenType grammar. The CFF table uses a complex encoding scheme for number values in order to save space. Some of these encoded values represent offsets to other internal data structures. My questions: How can I either use regular offset elements and feed them decoded values, or how can I programmatically create and configure offset elements? They do not seem to be documented much at all. Thank you!

Answer 1

Never mind, I figured it out myself. I ended up writing a custom data type script for the entire dictionary, which includes functions for decoding the offsets. I then mapped the structures using `currentMapper.mapStructureAtPosition`.
