Exporting annotations

To extract data from PDF to FDF, then export FDF as XFDF

PDFDoc doc = new PDFDoc(filename);

// Extract annotations to FDF.
// Optionally use e_both to extract both forms and annotations
FDFDoc doc_fields = doc.FDFExtract(PDFDoc.ExtractFlag.e_annots_only);
doc_fields.SetPdfFileName(filename);
doc_fields.Save(output_fdf_filename);

// Export annotations from FDF to XFDF.
doc_fields.SaveAsXFDF(output_xfdf_filename);
