  var ffileFontGetInfo = function (e) {
    const file_reader = new FileReader();
    file_reader.onload = (event) => {
      const json = AsposeFontGetBasicProperties(event.target.result, e.target.files[0].name);
      if (json.errorCode == 0) {
        document.getElementById('output').textContent = "Family name: " + json.familyName
          + "\nStyle: " + json.style
          + "\nFont type: " + json.fontType;
      }
