How to set the background color of a PDF document using iTextSharp

You can create a Rectangle object and set its BackgroundColor property. Use your Rectangle to initialize your Document.

Imports System
Imports System.IO

Imports iTextSharp.text
Imports iTextSharp.text.pdf

Public Class Chap0102

    Public Shared Sub Main()
        Console.WriteLine("Chapter 1 example 2: PageSize")

        ' step 1: creation of a document-object
        Dim pageSize As New Rectangle(144, 720)
        pageSize.BackgroundColor = New Color(&Hff, &Hff, &Hde) 
     '// pageSize.BackgroundColor.BackgroundColor = BaseColor.WHITE
        Dim document As New Document(pageSize)


            ' step 2:
            ' we create a writer that listens to the document
            ' and directs a PDF-stream to a file

            PdfWriter.getInstance(document, New FileStream("Chap0102.pdf", FileMode.Create))

            ' step 3: we open the document

            ' step 4: we Add some paragraphs to the document
            For i As Integer = 0 To 4
                document.Add(New Paragraph("Hello World"))

        Catch de As DocumentException
        Catch ioe As IOException
        End Try

        ' step 5: we close the document
    End Sub
End Class

How to add header and footer in iTextSharp

When you wish to display the page number and a title on every page, you need to make use of the PageEvents from the iTextSharp document settings. Create a class called: ITextEvents.cs with the following structure:

public class ITextEvents : PdfPageEventHelper

        // This is the contentbyte object of the writer
        PdfContentByte cb;

        // we will put the final number of pages in a template
        PdfTemplate headerTemplate, footerTemplate;

        // this is the BaseFont we are going to use for the header / footer
        BaseFont bf = null;

        // This keeps track of the creation time
        DateTime PrintTime = DateTime.Now;

        #region Fields
        private string _header;

        #region Properties
        public string Header
            get { return _header; }
            set { _header = value; }

        public override void OnOpenDocument(PdfWriter writer, Document document)
                PrintTime = DateTime.Now;
                bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
                cb = writer.DirectContent;
                headerTemplate = cb.CreateTemplate(100, 100);
                footerTemplate = cb.CreateTemplate(50, 50);
            catch (DocumentException de)

            catch (System.IO.IOException ioe)


        public override void OnEndPage(iTextSharp.text.pdf.PdfWriter writer, iTextSharp.text.Document document)
            base.OnEndPage(writer, document);

            iTextSharp.text.Font baseFontNormal = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 12f, iTextSharp.text.Font.NORMAL, iTextSharp.text.BaseColor.BLACK);

            iTextSharp.text.Font baseFontBig = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 12f, iTextSharp.text.Font.BOLD, iTextSharp.text.BaseColor.BLACK);

            PdfPCell pdfCell2 = new PdfPCell(p1Header);
            PdfPCell pdfCell3 = new PdfPCell();
            String text = "Page " + writer.PageNumber + " of ";

            //Add paging to header
                cb.SetFontAndSize(bf, 12);
                cb.SetTextMatrix(document.PageSize.GetRight(200), document.PageSize.GetTop(45));
                float len = bf.GetWidthPoint(text, 12);
                //Adds "12" in Page 1 of 12

            //add all three cells into PdfTable

            pdfTab.TotalWidth = document.PageSize.Width - 80f;

If you are using ImageCodecInfo

How to add a multi-page TIFF to a PDF using iTextSharp (VB.NET)

If you are ever stuck with a multi-page tiff, you will know how frustrating it is to get the images out and then add them to a pdf. This code snippet below shows how it’s done and feel free to leave a comment if you have used it and it worked.

'check if image exists
                Dim fi As New FileInfo(strImagePath)
                If fi.Exists Then

                    'save image in document
                    Dim gif As Image = Image.GetInstance(fi.FullName)
                    Dim pageWidth = doc.PageSize.Width - (10 + 10)
                    Dim pageHeight = doc.PageSize.Height - (40 + 10)

                    If fi.Extension.ToLower.EndsWith("tif") Then
                        Dim bmp As New System.Drawing.Bitmap(fi.FullName)
                        Dim total As Integer = bmp.GetFrameCount(System.Drawing.Imaging.FrameDimension.Page)
                        If total > 1 Then
                            For k As Integer = 0 To total - 1
                                bmp.SelectActiveFrame(System.Drawing.Imaging.FrameDimension.Page, k)
                                Dim img As iTextSharp.text.Image
                                img = iTextSharp.text.Image.GetInstance(bmp, System.Drawing.Imaging.ImageFormat.Bmp)
                                img.SetAbsolutePosition(10, 40)
                                img.ScaleToFit(pageWidth, pageHeight)
                        End If
                        gif.SetAbsolutePosition(10, 40)
                        gif.ScaleToFit(pageWidth, pageHeight)

Splitting PDF pages programatically using ABCPdf 7

As a programmer, you are sometimes faced with the issue of taking one existing PDF and extracting a specific page from it to show to the user. We have been using ABCPDF7 for this which you can download from their website.

Website Link:

First, we import the dlls into the project reference:

Reference Include=”ABCpdf, Version=, Culture=neutral, PublicKeyToken=a7a0b3f5184f2169, processorArchitecture=MSIL”>
<HintPath>…………..Program FilesWebSupergooABCpdf .NET 7.0ABCpdf.DLL</HintPath>

and the namespace at the top of the file. For this example I will be using VB.NET

Imports WebSupergoo.ABCpdf7
Imports WebSupergoo.ABCpdf7.Objects
Imports WebSupergoo.ABCpdf7.Atoms
Imports WebSupergoo.ABCpdf7.Operations

Declaring the source PDF and getting the number of pages:
Dim theSrc As Doc = New Doc()
Dim theCount As Integer = theSrc.PageCount

Pages start their count from 1 which is different from the 0-based arrays in .NET. Now we go through the pages of the document and save each page as a separate PDF file

Dim i As Integer
For i = 1 To theCount
Dim theDst As Doc = New Doc()
theDst.MediaBox.String = theSrc.MediaBox.String

theDst.Rect.String = theDst.MediaBox.String
theDst.Rect.Inset(0, 0)
theDst.Rect.Position(0, 0)
Dim theX As Double, theY As Double
theX = theDst.MediaBox.Width / 2
theY = theDst.MediaBox.Height / 2

theDst.Page = theDst.AddPage()
theDst.Save(Server.MapPath(“result” & CStr(i) & “.pdf”))

The files will be saved in the local folder and will be result1, result2, etc..

If you only want one specific page, PageNumberWanted is the page number starting from 1 and less than the number of pages available (can be retrieved via the count method above). The code is:

Dim theDst As Doc = New Doc()

theDst.MediaBox.String = theSrc.MediaBox.String
theDst.Rect.String = theDst.MediaBox.String
theDst.Rect.Inset(0, 0)
theDst.Rect.Position(0, 0)

theDst.Page = theDst.AddPage()
theDst.AddImageDoc(theSrc, PageNumberWanted, Nothing)

strPath = Server.MapPath(“ReportPageNumberWanted.pdf”)
