    // Load a document
    processor.LoadDocument("..\\..\\Document.pdf");

    // Access the first page properties
    PdfDocumentFacade facade = processor.DocumentFacade;
    PdfPageFacade page = facade.Pages[0];

    // Define a rubber stamp rectangle
    PdfRectangle rubberStampRectangle = new PdfRectangle(663, 526, 763, 576);

    string customStampFile = "..\\..\\Demo.pdf";
    using (FileStream fileStream = new FileStream(customStampFile, FileMode.Open, FileAccess.Read))
    {
        // Create a rubber stamp annotation
        PdfRubberStampAnnotationFacade rubberStamp =
            page.AddRubberStampAnnotation(rubberStampRectangle, fileStream, 2, true);
        rubberStamp.Author = "Jesse Faden";
    }

    // Save the result
    processor.SaveDocument("..\\..\\Result.pdf");
}

VB.NET

  Using processor As New PdfDocumentProcessor()
    ' Load a document
    processor.LoadDocument("..\..\Document.pdf")

    ' Access the first page properties
    Dim facade As PdfDocumentFacade = processor.DocumentFacade
    Dim page As PdfPageFacade = facade.Pages(0)

    ' Define a rubber stamp rectangle
    Dim rubberStampRectangle As New PdfRectangle(663, 526, 763, 576)

    Dim customStampFile As String = "..\..\Demo.pdf"
    Using fileStream As New FileStream(customStampFile, FileMode.Open, FileAccess.Read)

      ' Create a rubber stamp annotation
      Dim rubberStamp As PdfRubberStampAnnotationFacade =
        page.AddRubberStampAnnotation(rubberStampRectangle, fileStream, 2, True)
      rubberStamp.Author = "Jesse Faden"
    End Using

    ' Save the result
    processor.SaveDocument("..\..\Result.pdf")
