Are you using the PDF417 barcode object or the Paper Forms Barcode object configured for PDF417?
Thanks for your reply - I'm using the PDF417 barcode - The form does not need to be interactive where a user enters any data - the data is coming from an xml file - all the text fields populate okay when using acrofields in my C# program except for the PDF 417barcode - the text to merge with barcode appears on the form but there is no barcode displayed.
I tried switching to paperforms barcode but the
barcode fields remain empty. Are barcode reader
extensions required to make the barcodes visible?
