Core is the main engine that does document processing, canvas rendering and annotation managing.

linkInteracting with Core

Core provide an access point through a few global variables, one of them being CoreControls. This is a namespace containing WebViewer's main classes, objects and methods.

If you are using the default UI or legacy UI, you rarely have to worry about calling Core functions directly. However, you can choose not to use the provided UIs and create your own from scratch. The example below shows how to load a document in a custom viewer.

<!-- custom-ui.html -->
<html>
  <body>
    <h1>This is a custom viewer</h1>
    <div id='scroll-view'>
      <div id='viewer'></div>
    </div>
    <script src="core/external/jquery-3.2.1.min.js"></script>
    <script src="core/external/html2canvas.min.js"></script>
    <script src="core/CoreControls.js"></script>
    <script src="custom-ui.js"></script>
  </body>
</html>
// custom-ui.js
var docViewer = new CoreControls.DocumentViewer();
var partRetriever = new CoreControls.PartRetrievers.ExternalPdfPartRetriever('path/to/document.pdf');

docViewer.setScrollViewElement(document.getElementById('scroll-view'));
docViewer.setViewerElement(document.getElementById('viewer'));
docViewer.loadAsync(partRetriever);
