Font.js (FontJS)
Font.js (FontJS) is library helping parse/encode and manipulate TrueType font files. In a future there is a plan to extend support to OpenType fonts as well.
Example
import * as fontjs from "fontjs";
import { SeqStream, ByteStream } from "bytestreamjs";
async function fontTest()
{
const fontFetchResult = await fetch("./fonts/times.ttf");
const fontFetchBuffer = await fontFetchResult.arrayBuffer();
const font = fontjs.Font.fromStream(new SeqStream({ stream: new ByteStream({ buffer: fontFetchBuffer }) }));
const fontStream = new SeqStream();
const toStreamResult = font.toStream(fontStream);
}
