Generate Factur-X hybrid PDFs (ZUGFeRD / XRechnung) from simplified invoice input or from @e-invoice-eu/core Invoice data.
npm install factur-x-pdfBoth functions return a single A4 PDF with a human-readable invoice layout and embedded xrechnung.xml (XRechnung / ZUGFeRD).
Use generateXRechnungPdf with a flat InvoiceInput object. The library maps it to UBL internally.
