Open pdf.js with a data URL in IE11

Question

I\'m trying to use pdf.js for showing a document in a data URL on IE10. That is, something like this.

It works well with Firefox or Chrome, but in Internet Explorer

Answer 1

Ok, if someone runs to the same problem, I solved it by bypassing the lib's normal loading path, and as async5 advised, converting directly the data to a byte array.

That is, in viewer.js, add those lines under line 6856 :

  if (file && file.lastIndexOf('data:', 0) === 0) {
      // data: url-scheme. we will load those with direct conversion to byte array

      function convertDataURIToBinary(dataURI) {
          var base64Index = dataURI.indexOf(BASE64_MARKER) + BASE64_MARKER.length;
          var base64 = dataURI.substring(base64Index);
          var raw = window.atob(base64);
          var rawLength = raw.length;
          var array = new Uint8Array(new ArrayBuffer(rawLength));

          for(var i = 0; i < rawLength; i++) {
              array[i] = raw.charCodeAt(i);
          }
          return array;
      }

      // PDFViewerApplication.setTitleUsingUrl(file);
      PDFViewerApplication.open(convertDataURIToBinary(file), 0);

      return;
  }

(the base64 to byte array code is the one posted by Codetoffel here)
