Extract annotations from document Leave feedback

GroupDocs.Annotation provides an ability to extract annotations from document and serializing to XML format.
To achieve this you should:

• Instantiate Annotator object with input document path or stream;
• Instantiate LoadOptions object and set ImportAnnotation = true;
• Define variable with type List;
• Call Get method and return result to variable above;
• Instantiate XmlSerializer object with type List;
• Using FileStreamobject, serialize annotations to the file as on example below;

The following code demonstrates how to extract annotation metadata from document:

// for using this example input file ("annotated.pdf") must be with annotations
using (Annotator annotator = new Annotator("annotated.pdf"))
{
	List<AnnotationBase> annotations = annotator.Get();
    XmlSerializer formatter = new XmlSerializer(typeof(List<AnnotationBase>));
    using (FileStream fs = new FileStream("annotations.xml", FileMode.Create))
    {
    	fs.SetLength(0);
        formatter.Serialize(fs, annotations);
    }
}
