Good Luck.

	Dim input As String
	Dim output As String
	Dim water As String
	If txtPath.Text = "" Or txtimgpath.Text = "" Or txtoutpath.Text = "" Then
		MessageBox.Show("Please Enter Required Data", "Required Data Missing") 
	Else
		input = txtPath.Text
		water = txtimgpath.Text
		output = txtoutpath.Text
		AddWatermarkImage(input, output, water)
	End If
End Sub
 
Public Shared Sub AddWatermarkImage(ByVal sourceFile As String, ByVal outputFile As String, ByVal watermarkImage As String) 
	Dim reader As iTextSharp.text.pdf.PdfReader = Nothing
	Dim stamper As iTextSharp.text.pdf.PdfStamper = Nothing
	Dim img As iTextSharp.text.Image = Nothing
	Dim underContent As iTextSharp.text.pdf.PdfContentByte = Nothing
	Dim rect As iTextSharp.text.Rectangle = Nothing
	Dim X, Y As Single
	Dim pageCount As Integer = 0 
	Try
		If System.IO.File.Exists(sourceFile) Then
			reader = New iTextSharp.text.pdf.PdfReader(sourceFile) 
			rect = reader.GetPageSizeWithRotation(1)
			stamper = New iTextSharp.text.pdf.PdfStamper(reader, New System.IO.FileStream(outputFile, IO.FileMode.Create)) 
			img = iTextSharp.text.Image.GetInstance(watermarkImage)
			If img.Width > rect.Width OrElse img.Height > rect.Height Then
				img.ScaleToFit(rect.Width, rect.Height)
				X = (rect.Width - img.ScaledWidth) / 2
				Y = (rect.Height - img.ScaledHeight) / 2
			Else
				X = (rect.Width - img.Width) / 2
				Y = (rect.Height - img.Height) / 2
			End If
			img.SetAbsolutePosition(X, Y)
			pageCount = reader.NumberOfPages()
			For i As Integer = 1 To pageCount 
				underContent = stamper.GetUnderContent(i)
				underContent.AddImage(img)
			Next
			stamper.Close()
			reader.Close()
		Else
			MessageBox.Show("File Does Not Exist", "Missing File") 
		End If
		Catch ex As Exception 
		Throw ex
	End Try

Yes, Naimish and arithforu are the same users as me, I had problem while registering on the site, so I created naimish, after which arithforu worked fine, so posted it, on next naimish's account started working fine, so decided not to use arithforu and to use naimish as my proflie.


About http://forums.asp.net/p/1348029/2744846.aspx

Please see that that topic has been posted by me only, my username there is naimish only.

This code has been developed by me only in my project, if someone wants clarification can contact me for ruther details.

Thanks.
