Will it be possible (in the future?) to load local PDF files into the PDFviewer?
this is very usefull in WebApp!
It makes it possibele to show and/or print a (allready locally stored ) PDF

thanks

Import a PDF as BASE64 like:

github.com

mozilla/pdf.js/blob/master/examples/learning/helloworld64.html

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <title>'Hello, world!' base64 example</title>
</head>
<body>

<h1>'Hello, world!' example</h1>

<canvas id="the-canvas" style="border: 1px solid black; direction: ltr;"></canvas>

<script src="../../node_modules/pdfjs-dist/build/pdf.js"></script>

<script id="script">
  // atob() is used to convert base64 encoded PDF to binary-like data.
  // (See also https://developer.mozilla.org/en-US/docs/Web/API/WindowBase64/
  // Base64_encoding_and_decoding.)
  var pdfData = atob(
    'JVBERi0xLjcKCjEgMCBvYmogICUgZW50cnkgcG9pbnQKPDwKICAvVHlwZSAvQ2F0YWxvZwog' +

I found a solution:

var loBASE64data = my.dataProxy.getPDFFileAsBase64() ; //read file as Base64

var lcPDFData = atob(loBASE64data ); // convert

lcFileName = { “data”: lcPDFData }; // create JSON instead of URL

pdfviewer.load( lcFileName ) ;
