Extract FDF data from a PDF in Ruby

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

doc =

# Extract annotations to FDF.
# Optionally use e_both to extract both forms and annotations
doc_fields = doc.FDFExtract(PDFDoc::E_annot_only) #PDFDoc::E_forms_only

# Export annotations from FDF to XFDF.

# Optionally write XFDF to a string
XFDF_string = doc_fields.SaveAsXFDF()
