[web2py] Re: using PDF.js

[Massimo Di Pierro]

Assuming you have the download action in default py, then your PDF sources 
are accessible as

http://..../yourapp/default/download/<filename>.

(here filename is the web2py assigned filename stored in the upload field).

You just have to use that urls as source in the pdf.js example:

<canvas id="the-canvas"><canvas>

<script>

jQuery(function(){
  var url = '/yourapp/default/download/<filename>';
  PDFJS.getDocument(url).then(function getPdfHelloWorld(pdf) {
    pdf.getPage(1).then(function getPageHelloWorld(page) {
      var scale = 1.5;
      var viewport = page.getViewport(scale);
      var canvas = document.getElementById('the-canvas');
      var context = canvas.getContext('2d');
      canvas.height = viewport.height;
      canvas.width = viewport.width;
      var renderContext = {
        canvasContext: context,
        viewport: viewport
      };
      page.render(renderContext);
    });
  });

});
</script>
