Hello, I have developed an application with vb.net graphometric signature technology.
Now we are testing some functionality and I found that if I open a document with a signature field that has to sign the program correctly indicates that the field is to be signed.
But if I attach a document, as an additional page, and this document has already been signed signature fields, the program no longer detects the field without signing, but considers them all signed.
The code to see if the signature field is signed is the following:
Dim ret As Boolean = False
If (fld.GetValue Is Nothing) Then
Dim value As Obj = fld.GetValue ()
If valore.IsDict () Then
If valore.Find ( “ByteRange”) isnot Nothing Then
ret = True
'Signature field NOT Signed (2)
The code to attach new document is the following:
Using in_doc Good PDFDoc (_pathScan)Dim mediabox As Rect = _pdfdoc.GetPage (1) .GetMediaBox ()
Dim itr As PageIterator = in_doc.GetPageIterator ()
While itr.HasNext ()
Dim newPage As Page = itr.Current ()
itr. [Next] ()
You know how to give an indication?
Any suggestion is greatly appreciated.
