C#
C++/CLI

'Declaration
 
Public Sub SaveSignedCopy( _
   ByVal signedFile As Stream, _
   ByVal output As Stream _
)

'Usage
 
Dim instance As PdfComputedDigitalSignature

public void SaveSignedCopy( 
   Stream signedFile,
   Stream output
)

public:
void SaveSignedCopy( 
   Stream^ signedFile,
   Stream^ output
)

Parameters

signedFile: The input PDF file that was used to create the document from which this signature object was retrieved.
output: Destination stream where to save the signed copy.

Remarks

The stream used to create the Xfinium.Pdf.PdfFixedDocument object from which this signature was retrieved is required as input because the document does not keep a reference to the stream it was created from. Because the digital signatures are computed on the physical layout of the PDF file, it is impossible to recreate this layout from a loaded Xfinium.Pdf.PdfFixedDocument object.
