Export annotations using JavaScript

Only available with the Full API

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

const doc = await PDFNet.PDFDoc.createFromURL(filename);

// Extract annotations to FDF.
// Optionally use e_both to extract both forms and annotations
const doc_fields = await doc.fdfExtract(PDFNet.PDFDoc.ExtractFlag.e_annots_only); //PDFNet.PDFDoc.ExtractFlag.e_forms_only

// Export annotations from FDF to XFDF.
const xfdf_data = await doc_fields.saveAsXFDFAsString();

//optionally save the blob to a file or upload to a server
const blob = new Blob([xfdf_data], { type: 'application/xml' });
