iTextSharp in MVC, how to add image on 3rd page of pdf with custom x,y margins?

I am creating a PDF in MVC project using iTextSharp on .NET platform. I am sending a HTML div in "Download PDF" function and adding image from c# code using iTextSharp classes, but now I want to add an Image on 3rd page but unfortunately I am unable to do that. Please help me.
Please find the below code that I wrote for adding image on first page, last page and a loop for adding image on each page... (BUT I CAN NOT ADD AN IMAGE ONLY ON 3RD PAGE)...
using (MemoryStream stream = new System.IO.MemoryStream())
{
string Grid = GridHtml.Replace("<br>", "\n\r");
StringReader sr = new StringReader(Grid);
iTextSharp.text.Document pdfDoc = new iTextSharp.text.Document(PageSize.A4, 10f, 10f, 100f, 0f);
pdfDoc.SetMargins(50f, 50f, 90f, 0f);
PdfWriter writer = PdfWriter.GetInstance(pdfDoc, stream);
MyEvent events = new MyEvent();
writer.PageEvent = events;
pdfDoc.Open();
string imageURL1 = Server.MapPath("~/UploadedFiles/Calibehr.png");
iTextSharp.text.Image jpg12 = iTextSharp.text.Image.GetInstance(imageURL1);
////Resize image depend upon your need
jpg12.ScaleToFit(140f, 120f);
jpg12.SpacingBefore = 10f;
//////Give some space after the image
jpg12.SpacingAfter = 1f;
jpg12.Alignment = Element.ALIGN_CENTER;
jpg12.SetAbsolutePosition(40, 750);
pdfDoc.Add(jpg12);
if ((fc["hdnFormatType"] != "ManageService"))
{
string imageURL3 = Server.MapPath("~/UploadedFiles/Swati-Sign.png");
iTextSharp.text.Image jpgSign = iTextSharp.text.Image.GetInstance(imageURL3);
////Resize image depend upon your need

Try this one:- set positions also what you want.

iTextSharp PdfPCell align image to bottom of cell

I'm trying to align an image to the bottom-right of a cell.
I'm basically creating a table with two cells for each row. The cell contains text and an image, which I want to be aligned to the right bottom of the cells. Please refer to image
This is my code
PdfPTable table = new PdfPTable(2);
table.TotalWidth = 400f;
table.LockedWidth = true;
float[] widths = new float[] { 1.5f, 1.5f };
table.SetWidths(widths);
table.HorizontalAlignment = 0;
table.SpacingBefore = 50f;
table.SpacingAfter = 30f;
iTextSharp.text.Image logoImage = iTextSharp.text.Image.GetInstance(HttpContext.Current.Server.MapPath("~/Images/MyImage.png"));
logoImage.ScaleAbsolute(40, 40);
logoImage.Alignment = iTextSharp.text.Image.ALIGN_BOTTOM;
logoImage.Alignment = iTextSharp.text.Image.RIGHT_ALIGN;
foreach (EmployeeModel employee in employees)
{
PdfPCell cell = new PdfPCell();
cell.FixedHeight = 140f;
cell.PaddingLeft = 30f;
cell.PaddingRight = 10f;
cell.PaddingTop = 20f;
cell.PaddingBottom = 5f;
Paragraph p = new Paragraph(GetLabelCellText(Employee), NormalFont);
p.Alignment = Element.ALIGN_LEFT;
p.Alignment = Element.ALIGN_TOP;
cell.AddElement(p);
cell.AddElement(logoImage);
table.AddCell(cell);
}
How do I place the image at the bottom right of each cell (without affecting the position of the text of course).

The question is a bit ambiguous because you create a Table with two columns, but add cells without verifying the employees collection has an even number of elements, which will throw if not....
Assuming you really do want both the text and the image in a single cell, probably the simplest way to get the layout you want is to implement IPdfPCellEvent:
public class BottomRightImage : IPdfPCellEvent
{
public Image Image { get; set; }
public void CellLayout(
PdfPCell cell,
Rectangle position,
PdfContentByte[] canvases)
{
if (Image == null) throw new InvalidOperationException("image is null");
PdfContentByte canvas = canvases[PdfPTable.TEXTCANVAS];
Image.SetAbsolutePosition(
position.Right - Image.ScaledWidth - cell.PaddingRight,
position.Bottom + cell.PaddingBottom
);
canvas.AddImage(Image);
}
}
Then set the CellEvent property on the PdfPCell. Here's a simple working example:
using (var stream = new MemoryStream())
{
using (var document = new Document())
{
PdfWriter.GetInstance(document, stream);
document.Open();
var table = new PdfPTable(2)
{
HorizontalAlignment = Element.ALIGN_LEFT,
TotalWidth = 400f,
LockedWidth = true
};
var image = Image.GetInstance(imagePath);
image.ScaleAbsolute(40, 40);
var cellEvent = new BottomRightImage() { Image = image };
var testString =
#"first name: {0}
last name: {0}
ID no: {0}";
for (int i = 0; i < 2; ++i)
{
var cell = new PdfPCell()
{
FixedHeight = 140f,
PaddingLeft = 30f,
PaddingRight = 10f,
PaddingTop = 20f,
PaddingBottom = 5f
};
cell.CellEvent = cellEvent;
var p = new Paragraph(string.Format(testString, i))
{
Alignment = Element.ALIGN_TOP | Element.ALIGN_LEFT
};
cell.AddElement(p);
table.AddCell(cell);
}
document.Add(table);
}
File.WriteAllBytes(outputFile, stream.ToArray());
}
And PDF output:
An all-black square image is used to show the PdfPCell padding is taken into account.

draw table with filled cells in a PDF using iText for .NET

I want to draw a schedule, based on a table (including borders), where some of the cells are (partly) filled with a color. This color is based on PdfTemplate which is added as an image to the cell.
I've create a test project for it, and attached placed the output at: PDF output
In the example, I expect it to draw the filled line, everytime 2 blocks larger. As you can see, it is a bit more than the 2 blocks.
The template I create, should be the exact the size of the table cells. So I don't understand, why it keeps getting bigger every iteration.
Any ideas how to fix this?
public Test()
{
int cellWidth = 23;
int usernameCellWith = 86;
float[] scheduleTableColumnWidths = new float[33];
scheduleTableColumnWidths[0] = usernameCellWith;
for (int i = 1; i <= 32; i++)
scheduleTableColumnWidths[i] = cellWidth;
using (MemoryStream stream = new MemoryStream())
{
Rectangle rect = PageSize.GetRectangle("A4");
rect = new Rectangle(rect.Height, rect.Width, 90);
using (Document document = new Document(rect, 10f, 10f, 10f, 10f))
{
PdfWriter writer = PdfWriter.GetInstance(document, stream);
if (!document.IsOpen())
{
document.NewPage();
document.Open();
}
PdfPTable containerTable = new PdfPTable(1);
containerTable.DefaultCell.Border = Rectangle.NO_BORDER;
containerTable.WidthPercentage = 100;
PdfPTable scheduleTable = new PdfPTable(scheduleTableColumnWidths);
for (int iRow = 0; iRow <= 23; iRow++)
{
PdfPCell usernameCell = new PdfPCell(new Phrase("user "+ iRow));
usernameCell.FixedHeight = cellWidth;
scheduleTable.AddCell(usernameCell);
for (int iColumn = 1; iColumn <= 32; iColumn++)
{
PdfPCell cell = new PdfPCell();
cell.FixedHeight = cellWidth;
if (iColumn == 1 && iRow % 2 == 0)
{
float width = (float)(iRow + 1) * cellWidth;
PdfTemplate template = writer.DirectContent.CreateTemplate(width, cellWidth);
template.SetColorFill(new BaseColor(System.Drawing.ColorTranslator.FromHtml("#255C8A")));
template.Rectangle(0, 0, width, cellWidth);
template.Fill();
cell = new PdfPCell(Image.GetInstance(template));
}
scheduleTable.AddCell(cell);
}
scheduleTable.CompleteRow();
}
containerTable.AddCell(scheduleTable);
containerTable.CompleteRow();
document.Add(containerTable);
document.CloseDocument();
}
}
}

Do you absolutely need to use a PdfTemplate? Unless you've just posted a simplified version of your code it is screaming to use a colspan instead and then iText will just calculate everything for you.
Below is a modified version of what you posted. I moved some of your "magic numbers" to variables just to help my own mental process. They might not be named ideally but they do the job. Also, when working in a double for loop I recommend always looping over rows and columns and then performing logic. Your code loops over rows, does some logic for a "first cell" and then loops over a subset of the columns and performs more logic. Although absolutely 100% valid I personally find it confusing, especially when having to jump between 1 and 0 as a starting value.
Also, also, I very strongly recommend avoiding CompleteRow(). It exists to solve a certain problem but it also literally means "my logic above might be wrong so iText, could you just fudge the numbers for me?"
I commented most of what I changed so hopefully this is helpful.
public void Test() {
int cellWidth = 23;
int usernameCellWith = 86;
int maxNumberOfColumns = 32;
int maxNumberOfRows = 24;
float[] scheduleTableColumnWidths = new float[maxNumberOfColumns];
scheduleTableColumnWidths[0] = usernameCellWith;
for (int i = 1; i < maxNumberOfColumns; i++)
scheduleTableColumnWidths[i] = cellWidth;
using (MemoryStream stream = new MemoryStream()) {
iTextSharp.text.Rectangle rect = PageSize.GetRectangle("A4");
rect = new iTextSharp.text.Rectangle(rect.Height, rect.Width, 90);
using (Document document = new Document(rect, 10f, 10f, 10f, 10f)) {
PdfWriter writer = PdfWriter.GetInstance(document, stream);
//Unless this code is just a sample, a new document is never open and NewPage() is implied so these four lines could just be document.Open();
if (!document.IsOpen()) {
document.NewPage();
document.Open();
}
PdfPTable containerTable = new PdfPTable(1);
containerTable.DefaultCell.Border = iTextSharp.text.Rectangle.NO_BORDER;
containerTable.WidthPercentage = 100;
PdfPTable scheduleTable = new PdfPTable(scheduleTableColumnWidths);
//Loop through each row
for (int iRow = 0; iRow < maxNumberOfRows; iRow++) {
//Loop through each column
for (int iColumn = 0; iColumn < maxNumberOfColumns; iColumn++) {
//Placeholder variable that will be instantiated within the if statements below
PdfPCell cell;
//On the first column (of every row)
if (0 == iColumn) {
cell = new PdfPCell(new Phrase("user " + iRow));
//On the second column of every other row starting with the first (zeroth) row
} else if ((iColumn == 1) && (iRow % 2 == 0)) {
cell = new PdfPCell();
//Have the cell span based on the current row number
cell.Colspan = iRow + 1;
//Set the color
cell.BackgroundColor = new BaseColor(System.Drawing.ColorTranslator.FromHtml("#255C8A"));
//Tell the inner for loop that we've accounted for some cells already
iColumn += iRow;
//Every other cell
} else {
cell = new PdfPCell();
}
//This is weird
cell.FixedHeight = cellWidth;
//Regardless of the above, add a cell
scheduleTable.AddCell(cell);
}
}
containerTable.AddCell(scheduleTable);
document.Add(containerTable);
document.CloseDocument();
}
}

iTextSharp - dynamic content with a footer, using padding

I am attempting to create documents that are highly-variable in length, and make them something that can be table-driven. I am trying to use iTextSharp tables exclusively to create the documents, including footer verbiage. In the code below I’m trying to pad the very last cell to the exact amount equal to the remaining space, so that my footer will be placed exactly at the bottom of the document, tight against the bottom margin. This works fine when I try to use document margins of 1, 2, or 3 inches, but when I use 5 for example, my footer begins to wrap. I think this may simply be a case of bad math. Does anyone have any suggestions to correct this (outside of using Page Events)?
(*Note: there are 2 helper methods used in creating tables and measuring the height of a paragraph, also included in addition to the main code from a button click)
(*Note: each table has SplitLate set to false, to make the content flow from page to page evenly); all tables have a specific width, and the width is locked

Solved it by using absolute positioning. I calculate the position that the footer should be in, by adding the footer height to the value of the bottom margin. To alleviate concerns about overwriting existing content, I calculate the amount of available space remaining on the last page; if it's not enough for my footer, I add a new page and post my content at the beginning of the next page.
byte[] content;
using (MemoryStream output = new MemoryStream())
{
PdfReader pdf_rdr = new PdfReader(strpath);
PdfStamper stamper = new PdfStamper(pdf_rdr, output);
PdfContentByte pcb = stamper.GetOverContent(pdf_rdr.NumberOfPages);
PdfPTable ftbl = clsPDF.CreateTable(1, false, cell_padding_bottom: 0f);
Paragraph fp = new Paragraph(new Phrase("Line 1 of footer\r\nLine 2 of footer\r\nhere's more of my footer text:\r\nthis project was SOOOO much fun\r\nand stuff", fb8));
//get the height of the footer

Add Header and Footer for PDF using iTextsharp

How can I add header and footer for each page in the pdf.
Headed will contain just a text
Footer will contain a text and pagination for pdf (Page : 1 of 4)
How is this possible ? I tried to add the below line, but header does not show up in pdf.
document.AddHeader("Header", "Header Text");
This the code I am using for generation PDF :
protected void GeneratePDF_Click(object sender, EventArgs e)
{
DataTable dt = getData();
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=Locations.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Document document = new Document();
PdfWriter.GetInstance(document, Response.OutputStream);
document.Open();
iTextSharp.text.Font font5 = iTextSharp.text.FontFactory.GetFont(FontFactory.COURIER , 8);
PdfPTable table = new PdfPTable(dt.Columns.Count);
PdfPRow row = null;
float[] widths = new float[] { 6f, 6f, 2f, 4f, 2f };
table.SetWidths(widths);
table.WidthPercentage = 100;
int iCol = 0;
string colname = "";
PdfPCell cell = new PdfPCell(new Phrase("Locations"));
cell.Colspan = dt.Columns.Count;
foreach (DataColumn c in dt.Columns)
{
table.AddCell(new Phrase(c.ColumnName, font5));
}
foreach (DataRow r in dt.Rows)
{
if (dt.Rows.Count > 0)
{
table.AddCell(new Phrase(r[0].ToString(), font5));
table.AddCell(new Phrase(r[1].ToString(), font5));
table.AddCell(new Phrase(r[2].ToString(), font5));
table.AddCell(new Phrase(r[3].ToString(), font5));
table.AddCell(new Phrase(r[4].ToString(), font5));
}
}
document.Add(table);
document.Close();
Response.Write(document);
Response.End();
}
}

As already answered by #Bruno you need to use pageEvents.
Please check out the sample code below:
private void CreatePDF()
{
string fileName = string.Empty;
DateTime fileCreationDatetime = DateTime.Now;
fileName = string.Format("{0}.pdf", fileCreationDatetime.ToString(#"yyyyMMdd") + "_" + fileCreationDatetime.ToString(#"HHmmss"));
string pdfPath = Server.MapPath(#"~\PDFs\") + fileName;
using (FileStream msReport = new FileStream(pdfPath, FileMode.Create))
{
//step 1
using (Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 140f, 10f))
{
try
{
// step 2
PdfWriter pdfWriter = PdfWriter.GetInstance(pdfDoc, msReport);
pdfWriter.PageEvent = new Common.ITextEvents();
//open the stream
pdfDoc.Open();
for (int i = 0; i < 10; i++)
{
Paragraph para = new Paragraph("Hello world. Checking Header Footer", new Font(Font.FontFamily.HELVETICA, 22));
para.Alignment = Element.ALIGN_CENTER;
pdfDoc.Add(para);
pdfDoc.NewPage();
}
pdfDoc.Close();
}
catch (Exception ex)
{
//handle exception
}
finally
{
}
}
}
}
And create one class file named ITextEvents.cs and add following code:
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

public string Header

For iTextSharp 4.1.6, the last version of iTextSharp that was licensed as LGPL, the solution provided by Alvaro Patiño is both simple and effective.
Because documentation is somewhat scarse I'd like to extend his answer with this code snippet that can be used to change the appearance of the header and footer. By default they have a rather large font-size and a thick border, which many people will want to change.
// Parameters passed on to the function that creates the PDF
String headerText = "Your header text";
String footerText = "Page";
// Define a font and font-size in points (plus f for float) and pick a color
// This one is for both header and footer but you can also create seperate ones
Font fontHeaderFooter = FontFactory.GetFont("arial", 8f);
fontHeaderFooter.Color = Color.GRAY;
// Apply the font to the headerText and create a Phrase with the result
Chunk chkHeader = new Chunk(headerText, fontHeaderFooter);
Phrase p1 = new Phrase(chkHeader);
// create a HeaderFooter element for the header using the Phrase
// The boolean turns numbering on or off
HeaderFooter header = new HeaderFooter(p1, false);
// Remove the border that is set by default
header.Border = Rectangle.NO_BORDER;
// Align the text: 0 is left, 1 center and 2 right.
header.Alignment = 1;
// add the header to the document
document.Header = header;
// The footer is created in an similar way
// If you want to use numbering like in this example, add a whitespace to the
// text because by default there's no space in between them
if (footerText.Substring(footerText.Length - 1) != " ") footerText += " ";
Chunk chkFooter = new Chunk(footerText, fontHeaderFooter);
Phrase p2 = new Phrase(chkFooter);
// Turn on numbering by setting the boolean to true
HeaderFooter footer = new HeaderFooter(p2, true);
footer.Border = Rectangle.NO_BORDER;
footer.Alignment = 1;
document.Footer = footer;
// Open the Document for writing and continue creating its content
document.Open();

We don't talk about iTextSharp anymore. You are using iText 5 for .NET. The current version is iText 7 for .NET.
Obsolete answer:
The AddHeader has been deprecated a long time ago and has been removed from iTextSharp. Adding headers and footers is now done using page events. The examples are in Java, but you can find the C# port of the examples here and here (scroll to the bottom of the page for links to the .cs files).
Make sure you read the documentation. A common mistake by many developers have made before you, is adding content in the OnStartPage. You should only add content in the OnEndPage. It's also obvious that you need to add the content at absolute coordinates (for instance using ColumnText) and that you need to reserve sufficient space for the header and footer by defining the margins of your document correctly.
Updated answer:
If you are new to iText, you should use iText 7 and use event handlers to add headers and footers. See chapter 3 of the iText 7 Jump-Start Tutorial for .NET.
When you have a PdfDocument in iText 7, you can add an event handler:
PdfDocument pdf = new PdfDocument(new PdfWriter(dest));
pdf.addEventHandler(PdfDocumentEvent.END_PAGE, new MyEventHandler());
This is an example of the hard way to add text at an absolute position (using PdfCanvas):
protected internal class MyEventHandler : IEventHandler {
public virtual void HandleEvent(Event #event) {
PdfDocumentEvent docEvent = (PdfDocumentEvent)#event;
PdfDocument pdfDoc = docEvent.GetDocument();
PdfPage page = docEvent.GetPage();
int pageNumber = pdfDoc.GetPageNumber(page);
Rectangle pageSize = page.GetPageSize();
PdfCanvas pdfCanvas = new PdfCanvas(page.NewContentStreamBefore(), page.GetResources(), pdfDoc);
//Add header
pdfCanvas.BeginText()
.SetFontAndSize(C03E03_UFO.helvetica, 9)
.MoveText(pageSize.GetWidth() / 2 - 60, pageSize.GetTop() - 20)
.ShowText("THE TRUTH IS OUT THERE")
.MoveText(60, -pageSize.GetTop() + 30)
.ShowText(pageNumber.ToString())
.EndText();
pdfCanvas.Release();
}
}
This is a slightly higher-level way, using Canvas:
protected internal class MyEventHandler : IEventHandler {
public virtual void HandleEvent(Event #event) {
PdfDocumentEvent docEvent = (PdfDocumentEvent)#event;
PdfDocument pdfDoc = docEvent.GetDocument();
PdfPage page = docEvent.GetPage();
int pageNumber = pdfDoc.GetPageNumber(page);
Rectangle pageSize = page.GetPageSize();
PdfCanvas pdfCanvas = new PdfCanvas(page.NewContentStreamBefore(), page.GetResources(), pdfDoc);
//Add watermark
Canvas canvas = new Canvas(pdfCanvas, pdfDoc, page.getPageSize());
canvas.setFontColor(Color.WHITE);
canvas.setProperty(Property.FONT_SIZE, 60);
canvas.setProperty(Property.FONT, helveticaBold);
canvas.showTextAligned(new Paragraph("CONFIDENTIAL"),
298, 421, pdfDoc.getPageNumber(page),
TextAlignment.CENTER, VerticalAlignment.MIDDLE, 45);
pdfCanvas.Release();
}
}
There are other ways to add content at absolute positions. They are described in the different iText books.

The answers to this question, while they are correct, are very unnecessarily complicated. It doesn't take that much code for text to show up in the header/footer. Here is a simple example of adding text to the header/footer.
The current version of iTextSharp works by implementing a callback class which is defined by the IPdfPageEvent interface. From what I understand, it's not a good idea to add things during the OnStartPage method, so instead I will be using the OnEndPage page method. The events are triggered depending on what is happening to the PdfWriter
First, create a class which implements IPdfPageEvent. In the:
public void OnEndPage(PdfWriter writer, Document document)
function, obtain the PdfContentByte object by calling
PdfContentByte cb = writer.DirectContent;
Now you can add text very easily:
ColumnText ct = new ColumnText(cb);
cb.BeginText();
cb.SetFontAndSize(BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, BaseFont.NOT_EMBEDDED), 12.0f);
//Note, (0,0) in this case is at the bottom of the document
cb.SetTextMatrix(document.LeftMargin, document.BottomMargin);
cb.ShowText(String.Format("{0} {1}", "Testing Text", "Like this"));
cb.EndText();
So the full for the OnEndPage function will be:
public void OnEndPage(PdfWriter writer, Document document)
{
PdfContentByte cb = writer.DirectContent;
ColumnText ct = new ColumnText(cb);
cb.BeginText();
cb.SetFontAndSize(BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, BaseFont.NOT_EMBEDDED), 12.0f);
cb.SetTextMatrix(document.LeftMargin, document.BottomMargin);
cb.ShowText(String.Format("{0} {1}", "Testing Text", "Like this"));
cb.EndText();
}
This will show up at the bottom of your document. One last thing. Don't forget to assign the IPdfPageEvent like this:
writter.PageEvent = new PDFEvents();
To the PdfWriter writter object
For the header it is very similar. Just flip the SetTextMatrix y coordinate:
cb.SetTextMatrix(document.LeftMargin, document.PageSize.Height - document.TopMargin);

Just add this line before opening the document (must be before):
document.Header = new HeaderFooter(new Phrase("Header Text"), false);
document.Open();

For those just needing headers!!!
All of these answers are way too complicated if you are designing your page via PdfPTables (which is the easiest way IMO)! If you are working with PdfPTables you can literally just define your first x number of table rows as header rows. They will then repeat on every page.
No need to invoke bulky page events.
1 line of code:
myPdfPTable.HeaderRows = myHeaderRowsAmount

Easy codes that work successfully:
protected void Page_Load(object sender, EventArgs e)
{
.
.
using (MemoryStream ms = new MemoryStream())
{
.
.
iTextSharp.text.Document doc = new iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 36, 36, 54, 54);
iTextSharp.text.pdf.PdfWriter writer = iTextSharp.text.pdf.PdfWriter.GetInstance(doc, ms);
writer.PageEvent = new HeaderFooter();
doc.Open();
.
.
// make your document content..
.
.
doc.Close();
writer.Close();
// output
Response.ContentType = "application/pdf;";
Response.AddHeader("Content-Disposition", "attachment; filename=clientfilename.pdf");
byte[] pdf = ms.ToArray();
Response.OutputStream.Write(pdf, 0, pdf.Length);
}
.
.
.
}
class HeaderFooter : PdfPageEventHelper
{
public override void OnEndPage(PdfWriter writer, Document document)
{
// Make your table header using PdfPTable and name that tblHeader
.
.
tblHeader.WriteSelectedRows(0, -1, page.Left + document.LeftMargin, page.Top, writer.DirectContent);
.
.
// Make your table footer using PdfPTable and name that tblFooter
.
.
tblFooter.WriteSelectedRows(0, -1, page.Left + document.LeftMargin, writer.PageSize.GetBottom(document.BottomMargin), writer.DirectContent);

To Use:
Document pdfDoc = new Document(PageSize.LEGAL.Rotate(), 10, 10, 25, 25);
System.IO.MemoryStream mStream = new System.IO.MemoryStream();
PdfWriter writer = PdfWriter.GetInstance(pdfDoc, mStream);
MyCode.HeaderFooter headers = new MyCode.HeaderFooter();
writer.PageEvent = headers;
..
..
Build the string array for the headers
...
DefineFont passFont = new DefineFont();
// always set this to the largest font used
headers.fontPointSize = 8;
// set up the highlight or bold font
passFont.fontFamily = "Helvetica";
passFont.fontSize = 8;
passFont.isBold = true;
passFont.isItalic = false;
passFont.isUnderlined = false;
passFont.foreColor = BaseColor.BLACK;
headers.boldFont = passFont;
// now setup the normal text font
passFont.fontSize = 7;
passFont.isBold = false;
headers.normalFont = passFont;
headers.leftMargin = 10;
headers.bottomMargin = 25;
headers.rightMargin = 10;
headers.topMargin = 25;
headers.PageNumberSettings = HeaderFooter.PageNumbers.FooterPlacement;
headers.footerLine = "Page";
headers.headerLines = parmLines.ToArray();
pdfDoc.SetMargins(headers.leftMargin, headers.rightMargin, headers.topMargin + headers.headerheight, headers.bottomMargin + headers.footerHeight);
pdfDoc.Open();
// the new page is necessary due to a bug in in the current version of itextsharp
pdfDoc.NewPage();
... now your headers and footer will be handled automatically
