fill_form: Fills the fillable PDF's form fields with the data from a FDF file or XFDF file.
If the input FDF file includes Rich Text formatted data in addition to plain text, then the Rich Text data is packed into the form fields as well as the plain text. VeryPDF Form Filler Cloud API also sets a flag that cues Reader/Acrobat to generate new field appearances based on the Rich Text data. So when the user opens the PDF, the viewer will create the Rich Text appearance on the spot. If the user's PDF viewer does not support Rich Text, then the user will see the plain text data instead. If you flatten this form before Acrobat has a chance to create (and save) new field appearances, then the plain text field data is what you'll see.
