Function measureWithPretext

Measures text with Pretext, in the fonts the page has, for laying out a document's pages in a browser. Pretext needs a canvas to measure with, an OffscreenCanvas or a page's, so it doesn't work in Node.

Load the fonts first, such as with document.fonts.load("11pt Calibri"): until a font has loaded, the browser measures text in another, and Pretext keeps the widths it measured.

import * as pretext from "@chenglou/pretext";
import { estimatePageNumbersWith, measureWithPretext } from "docx/layout";

new Document({ pageNumbers: estimatePageNumbersWith({ measureWidth: measureWithPretext(pretext) }), sections: [...] });
