I am trying to use pdf.js to load pdf into a web application so that I can further extract information from the pdf file live. But I am getting this error with a very minimal example.
I have tried wrapping the code in $(document).ready() as suggested in
Uncaught ReferenceError: PDFJS is not defined when initialising PDF.JS
I am not able to access PDFJS in console either.
Below is the code I am using (from
https://www.sitepoint.com/custom-pdf-rendering/
)
<!DOCTYPE html>
<meta charset="utf-8"/>
<title>PDF.js Learning</title>
</head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script type="text/javascript" src="https://mozilla.github.io/pdf.js/build/pdf.js"></script>
<script type="text/javascript" src="https://mozilla.github.io/pdf.js/build/pdf.worker.js"></script>
<script>
$(document).ready(function () {
var url = "https://github.com/mozilla/pdf.js/blob/master/web/compressed.tracemonkey-pldi-09.pdf";
// Asynchronous download PDF
PDFJS.getDocument(url)
.then(function(pdf) {
return pdf.getPage(1);
.then(function(page) {
// Set scale (zoom) level
var scale = 1.5;
// Get viewport (dimensions)
var viewport = page.getViewport(scale);
// Get canvas#the-canvas
var canvas = document.getElementById('the-canvas');
// Fetch canvas' 2d context
var context = canvas.getContext('2d');
// Set dimensions to Canvas
canvas.height = viewport.height;
canvas.width = viewport.width;
// Prepare object needed by render method
var renderContext = {
canvasContext: context,
viewport: viewport
// Render PDF page
page.render(renderContext);
</script>
<canvas id='the-canvas'></canvas>
</body>
</html>
