How to load a TIFF file in WebViewer?

WebViewer requires the Full API to load a TIFF file. See this guide for how to setup full API.

You can then use the full API to manually create a document, add the TIFF image to the document and load the document in WebViewer:

1WebViewer({
2    path: 'lib',
3    fullAPI: true,
4  }, document.getElementById('viewer'))
5.then(function(instance) {
6  var PDFNet = instance.PDFNet;
7
8  var newDoc;
9  
10  PDFNet.runWithoutCleanup(function() {
11    //create an empty document
12    return PDFNet.PDFDoc.create()
13      .then(function(doc) {
14        newDoc = doc;
15        newDoc.initSecurityHandler();
16        newDoc.lock();
17        return PDFNet.Filter.createURLFilter("./files/test.tif");
18      })
19      .then(function(tiffFile) {
20        return PDFNet.Convert.fromTiff(newDoc, tiffFile);
21      }).then(function() {
22        newDoc.unlock();
23        instance.loadDocument(newDoc);
24      });
25  });
26});
