This can be done using the Barcode and PdfStamper
classes. In general, you should probably:
-create a PdfReader to read your source PDF and obtain
its page count
-create a PdfStamper to write the stamped output
-create your Barcode subclass instance (eg Barcode39)
-get a PdfTemplate from your bar code's
getTemplateWithBarcode() method. You may be able to
use the PdfContentByte returned from your PdfStamper's
getOverContent(1).
-for each page in the stamper:
call
stamper.getOverContent(pageNum).addTemplate(barcodeTemplate,
...translation matrix stuff...)
That's what I pieced together fairly quickly from the
API... Paulo may fill in some blanks later but that
may be enough for a start.
