Module: Fontisan::Ufo::Convert::ToTtc

Defined in:
lib/fontisan/ufo/convert/to_ttc.rb

Overview

UFO → TrueType Collection (.ttc). Two-step:

1. Compile UFO → TTF in tmpdir.
2. Load + feed to Collection::Builder with format: :ttc.

A single UFO produces a single-face collection. Multi-face collections from multiple UFOs are a separate concern (the Stitcher pipeline handles that case).
