Add WaterMark In PDF Files
 
  • Add Reference of iTextSharp.dll
  • btnAddWaterMark_Click is a button name.
  • AddWatermarkImage is a method name.
  • Enter Input File's Path in input
  • Enter Output File's Path in output
  • Enter Image's Path in water
Good Luck.
Code:

Private Sub btnAddWaterMark_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddWaterMark.Click
        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
End Sub

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.

Moved to Articles section and also try using only one account as use of 2 accounts simultaneously is not allowed.

Yes, as I said, I have decided to use naimish instead of arithforu, you can delete arithforu if you want. Thanks.
