Zitat von MALET Vincent <[email protected]>:
Hello,
Hi Vincent,
I would like to know if it is possible to add multiple signature
fields into an existing PDF document using PDFBOX
technicaly it is possible, but you can only use one at a time for signing.
I've seen the
org.apache.pdfbox.pdmodel.interactive.digitalsignature.PDSignature
class which helps managing one digital signature per document but no
information about adding a signature field as it is explained here :
http://www.adobe.com/designcenter/acrobat/articles/acr8at_signpdf.html
as you said, you don't need the signature dictionary (PDSignature). A
signature field[1] / annontation[2] that you link with the page is all
you need. The field and the annotation can be merged as described in [1]
Thanks for your response.
Regards,
Vincent
Best Regards
Thomas
