Hyperlinks are a type of annotation which BuildVu fully supports. Annotations are written out to an annotations.json file which can be parsed programmatically, allowing annotations to be easily added, modified or removed.
The IDRViewer fully supports annotations as long as the document is loaded from a web server. The IDRViewer relies on an AJAX request to load the annotations which may be blocked when the document is loaded from the local file system. Web browsers such as Chrome, Internet Explorer and Safari block such AJAX requests for security reasons (see relevant Chromium ticket).
If you are using the content mode, you will need to implement your own solution for loading and displaying annotations.
Note: Our online converter has external hyperlinks disabled for security reasons. They are enabled in our customer and trial downloads.
