parse#

const parse: (data, index) => number = wasm.font_parse

Parse a font file and register it, returning the id every other text_* export takes. index selects a face inside a collection (.ttc/.otc/.dfont) and is 0 for a plain font. The bytes are copied into the registry, so the caller's buffer is free afterwards.

number

Returns#

number

setVariations#

const setVariations: (id, settings_json) => void = wasm.font_set_variations

Pin a variable font's design axes: [{"axis":"wght","value":700}]. An empty list restores the defaults.
