Extract FDF data from a PDF

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

PDFDoc doc = new PDFDoc(filename);

// Extract form fields data to FDF.
// Optionally use e_both to extract both forms and annotations
FDFDoc doc_fields = doc.fdfExtract(PDFDoc.e_forms_only);
doc_fields.setPDFFileName(filename);
doc_fields.save(output_fdf_filename);

// Export form fields data from FDF to XFDF.
doc_fields.saveAsXFDF(output_xfdf_filename);
