+//Minimal PDF rendering and text-selection example using pdf.js by Vivin Suresh Paliath (http://vivin.net)
+//This example uses a built version of pdf.js that contains all modules that it requires.
+//
+//
+//The problem with understanding text selection was that the text selection code has heavily intertwined
+//with viewer.html and viewer.js. I have extracted the parts I need out of viewer.js into a separate file
+//which contains the bare minimum required to implement text selection. The key component is TextLayerBuilder,
+//which is the object that handles the creation of text-selection divs. I have added this code as an external
+//resource.
+//
+//This demo uses a PDF that only has one page. You can render other pages if you wish, but the focus here is
+//just to show you how you can render a PDF with text selection. Hence the code only loads up one page.
+//
+//The CSS used here is also very important since it sets up the CSS for the text layer divs overlays that
+//you actually end up selecting.
+
+window.onload = function () {
+
+ var scale = 1.5; //Set this to whatever you want. This is basically the "zoom" factor for the PDF.
