  const AsposePageWebWorker = new Worker("AsposePageforJS.js");
  AsposePageWebWorker.onerror = evt => console.log(`Error from Web Worker: ${evt.message}`);
  AsposePageWebWorker.onmessage = evt => document.getElementById('output').textContent = 
    (evt.data == 'ready') ? 'library loaded!' :
      (evt.data.json.errorCode == 0) ? `Result:\n${DownloadFile(evt.data.json.fileNameResult, "application/image", evt.data.params[0])}` : `Error: ${evt.data.json.errorText}`;

  const fPsAsPdf = e => {
    const file_reader = new FileReader();
    file_reader.onload = event => {
      /*Convert a Postscript to PDF - Ask Web Worker*/
      AsposePageWebWorker.postMessage({ "operation": 'AsposePSSaveAsPdf', "params": [event.target.result, e.target.files[0].name, true] }, [event.target.result]);
    };
    file_reader.readAsArrayBuffer(e.target.files[0]);
  };

  /*Make a link to download the result file*/
  const DownloadFile = function (filename, mime, content) {
      mime = mime || "application/octet-stream";
      var link = document.createElement("a"); 
      link.href = URL.createObjectURL(new Blob([content], {type: mime}));
      link.download = filename;
      link.textContent = filename;
      link.title = "Click here to download the file";
      document.getElementById('fileDownload').appendChild(link);
      document.getElementById('fileDownload').appendChild(document.createElement("br"));
