Hi,
For signatures we are using SAPI (Cosign). the PDF can accept multiple
signatures.
Once i open the PDF document using PdfStamper then loop thru the Acro Fields to
update the content its removing the previous signatures.
Please help.
i have used PdfStamper with append mode.
This is what i am trying to do
-------------------------------------
PdfReader reader = new PdfReader(pdfDoc);
//create memory stream to hold the pdf document
MemoryStream pdfMemoryStream = new MemoryStream();
PdfStamper stamp1 = new PdfStamper(reader, pdfMemoryStream, '\0', true);
//retrieve all the PDF fields
AcroFields form1 = stamp1.AcroFields;
// update the fields with the data.
byte[] buffer = pdfMemoryStream.ToArray();
// save the file in Sharepoint
SPFile file = fileCollection.Add(m_fieldDocName, buffer, true);
Please help
Thanks in advance
Usman
