How to export XFDF for a single annotation?

[Matt Parizeau]

Q:

I'm using the following code and want to extract the XFDF for individual annotations. Is this possible?

annotationManager = this.webViewerInstance.getInstance().getDocumentViewer().getAnnotationManager()
annotationManager.on('annotationChanged', function(event, annotations, actionType) {
  if (!event.imported) {
    annotations.forEach(function(annotation) {
      // Extract xfdf string for each annotation
    });
  }
});

A:

You can use the annotList option from exportAnnotations http://www.pdftron.com/webviewer/demo/lib/html5/doc/symbols/CoreControls.AnnotationManager.html#exportAnnotations. For example:

annotations.forEach(function(annotation) {
  annotationManager.exportAnnotations({
    annotList: [annotation]
  });
});
