Class Font

This record is used to persist information related to custom fonts on Standalone deployments. Custom fonts need to be specified during the instance load and correctly fetched. They will be used while rendering the document contents and exporting its annotations.

Example

Create a new Font object

const fetcher = name =>
  fetch(`https://example.com/${name}`).then(r => {
    if (r.status === 200) {
      return r.blob();
    } else {
      throw new Error();
    }
  });

const customFonts = ["arial.ttf", "helvetica.ttf", "tahoma.ttf"]
  .map(font => new NutrientViewer.Font({ name: font, callback: fetcher }));

NutrientViewer.load({
  customFonts,
  regular options...
}).then(instance => {});
