Exports

Symbol Type Description
FEAT_FLAGS const { EXCLUSIVE: 0x8000, DYNAMIC_DEFAULT: 0x4000, DEFAULT_MASK: 0x00FF } — bit masks applied to each feature's featureFlags (feat.js lines 22–26).
parseFeat function (bytes) => { version, featureNameCount, features }. Each features[i] is { feature, nSettings, settingTableOffset, featureFlags, exclusive, defaultSetting, nameIndex, settings: { setting, nameIndex }[] } — a previous revision of this page omitted the top-level featureNameCount and the per-feature settingTableOffset/exclusive/defaultSetting fields (feat.js lines 52–83).
aatFeat factory Factory.

Usage

import fw from '@awacloud/fw';
import { fw_require, modules, extras } from '@awacloud/fonts';

for (const m of [...fw_require, ...modules, ...extras]) fw.runtime.register(m);
const { parseFeat } = fw.runtime.resolve('aatFeat');
const feat = parseFeat(sfnt.tables.feat.bytes);

Notes

  • Labels are resolved via the name table of the same font.
  • This module fully parses every feature/setting record — no state-machine deferral applies here (contrast with ankr/kerx/lcar/morx/prop, see ./README.md).
  • Requires the fonts-apple-aat bundle.
