ItextSharp Columntext in my PDF

i´m working at a little program.
I have a PDF with 17 pages and i want to place columntext on some of them.
But after creating the PDF i get only Page one out.
{
string newfile = "newfile.pdf";
FileStream fs = new FileStream(newfile, FileMode.Create, FileAccess.Write);
PdfReader reader = null;
PdfWriter writer = null;
PdfImportedPage page = null;
Document dc = null;
dc = new Document(reader.GetPageSizeWithRotation(1));
writer = PdfWriter.GetInstance(dc, fs);
dc.Open();
int numberOfPages = reader.NumberOfPages;
PdfContentByte cb = writer.DirectContent;
reader = new PdfReader(pdfPath);
for (int i = 1; i <= numberOfPages; i++)
{
page = writer.GetImportedPage(reader, startPage);
cb.AddTemplate(page, 0, 0);
if (startPage == 1)
{
cb.BeginText();
ColumnText.ShowTextAligned(cb, Element.ALIGN_LEFT, new Phrase(new Chunk("<<NAME>>", FontFactory.GetFont("c:\\windows\\fonts\\Roboto-BoldCondensed.ttf", 15, BaseColor.BLACK)).SetSkew(0, 10)), 367.7F, 140.7F, 10);
cb.EndText();
}
startPage++;
}
dc.Close();
fs.Close();
writer.Close();
reader.Close();
}

I tried to use stamper but the PDF file ist damaged. Something is wrong with my code string newfile = "newfile2.pdf";
FileStream fs = new FileStream(newfile, FileMode.Create, FileAccess.Write);
PdfReader reader = null;
reader = new PdfReader(pdfPath);
PdfStamper stamper = new PdfStamper(reader,fs);
int numberOfPages = reader.NumberOfPages;
PdfContentByte cb;
for (int i = 1; i <= numberOfPages; i++)
{
cb = stamper.GetOverContent(i);
ColumnText.ShowTextAligned(cb, Element.ALIGN_LEFT, new Phrase(new Chunk("<<NAME>>", FontFactory.GetFont("c:\\windows\\fonts\\Roboto-BoldCondensed.ttf", 15, BaseColor.BLACK)).SetSkew(0, 10)), 367.7F, 140.7F, 10);
}
fs.Close();
reader.Close();

Add image with text in header of every page in pdf file using itextsharp

When we use below code it add only one image. Is any other option to add image & text on every page?
private void AddHeader(string filephysicalpath, string nfile)
{
byte[] bytes = System.IO.File.ReadAllBytes(filephysicalpath);
String path = ConfigurationManager.AppSettings["Documentheader"].ToString() + Session["headerImg"];
Stream inputImageStream = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read);
Font blackFont = FontFactory.GetFont("Arial", 12, Font.BOLD, BaseColor.BLACK);
using (MemoryStream stream = new MemoryStream())
{
PdfReader reader = new PdfReader(bytes);
using (PdfStamper stamper = new PdfStamper(reader, stream))
{
int pages = reader.NumberOfPages;
for (int i = 1; i <= pages; i++)
{
string footer = Convert.ToString(Session["Footer"]);
if (Session["Footer"] != null)
{
// Phrase ft = new Phrase(footer, blackFont);
float marginLR = 36;
float marginB = 2;
float footerHeight = 10;
Rectangle pagesize = reader.GetCropBox(i);
if (pagesize == null)
{
pagesize = reader.GetPageSize(i);
}
Rectangle rect = new Rectangle(
pagesize.Left + marginLR, pagesize.Top + marginB,
pagesize.Right - marginLR, pagesize.Top + marginB + footerHeight
);
iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(inputImageStream);
image.SetAbsolutePosition(rect.Left, rect.Top - image.ScaledHeight);
var pdfContentByte = stamper.GetOverContent(1);
pdfContentByte.AddImage(image);
inputImageStream.Seek(0L, SeekOrigin.Begin);
// ct.AddElement(new PdfPTableHeader (image));
}
}
}
reader.Close();
bytes = stream.ToArray();
}
System.IO.File.WriteAllBytes(filephysicalpath, bytes);
}

In your loop you do
var pdfContentByte = stamper.GetOverContent(1);
pdfContentByte.AddImage(image);
I.e. you always use the OverContent of page 1 and add the image to it. Instead you should use the OverContent of page i:
var pdfContentByte = stamper.GetOverContent(i);
pdfContentByte.AddImage(image);
Furthermore, you should import the image only once, i.e. move the line
iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(inputImageStream);
above the loop.

Have you try to set inputImageStream to beggining before next use?
inputImageStream.Seek(0L, SeekOrigin.Begin);
Meybe its pointer is on the end of stream and next call return empty image?

It is possible to cut an image of ItextSharp.Text.Image?

I'm creating a pdf file from an large image, but my image is too large, and it does not fit in the only page. then i need split this image to create more pages.
any idea?
public FileResult ResultadoParaPdf(string file)
{
string fileStringReplace = file.Replace("data:image/png;base64,", "");
var image = Convert.FromBase64String(fileStringReplace);
const int HorizontalMargin = 40;
const int VerticalMargin = 40;
using (var outputMemoryStream = new MemoryStream())
{
using (var pdfDocument = new Document(PageSize.A4, HorizontalMargin, HorizontalMargin, VerticalMargin, VerticalMargin))
{
iTextSharp.text.pdf.PdfWriter pdfWriter = PdfWriter.GetInstance(pdfDocument, outputMemoryStream);
pdfWriter.CloseStream = false;
pdfDocument.Open();
PdfPTable table = new PdfPTable(1);
table.WidthPercentage = 100;
Image img = Image.GetInstance(image);
img.WidthPercentage = 100;
PdfPCell c = new PdfPCell(img, true);
c.Border = PdfPCell.NO_BORDER;
c.Padding = 5;
c.Image.ScaleToFit(750f, 750f);
table.AddCell(c);
pdfDocument.Add(table);
pdfDocument.Close();
byte[] created = outputMemoryStream.ToArray();
outputMemoryStream.Write(created, 0, created.Length);
outputMemoryStream.Position = 0;
return File(created, "application/pdf", "teste.pdf");
}
}
}

Insert page into existing PDF using itextsharp

We are using itextsharp to create a single PDF from multiple PDF files. How do I insert a new page into a PDF file that has multiple pages already in the file? When I use add page it is overwriting the existing pages and only saves the 1 page that was selected.
Here is the code that I am using to add the page to the existing PDF:
PdfReader reader = new PdfReader(sourcePdfPath);
Document document = new Document(reader.GetPageSizeWithRotation(1));
PdfCopy pdfCopy = new PdfCopy(document, new System.IO.FileStream(outputPdfPath, System.IO.FileMode.Create));
MemoryStream memoryStream = new MemoryStream();
PdfWriter writer = PdfWriter.GetInstance(document, memoryStream);
document.AddDocListener(writer);
document.Open();
for (int p = 1; p <= reader.NumberOfPages; p++)
{
if (pagesToExtract.FindIndex(s => s == p) == -1) continue;
document.SetPageSize(reader.GetPageSize(p));
document.NewPage();
PdfContentByte cb = writer.DirectContent;
PdfImportedPage pageImport = writer.GetImportedPage(reader, p);
int rot = reader.GetPageRotation(p);
if (rot == 90 || rot == 270)
{
cb.AddTemplate(pageImport, 0, -1.0F, 1.0F, 0, 0, reader.GetPageSizeWithRotation(p).Height);
}
else
{
cb.AddTemplate(pageImport, 1.0F, 0, 0, 1.0F, 0, 0);
}
pdfCopy.AddPage(pageImport);
}
pdfCopy.Close();

This code works. You need to have a different file to output the results.
private static void AppendToDocument(string sourcePdfPath1, string sourcePdfPath2, string outputPdfPath)
{
using (var sourceDocumentStream1 = new FileStream(sourcePdfPath1, FileMode.Open))
{
using (var sourceDocumentStream2 = new FileStream(sourcePdfPath2, FileMode.Open))
{
using (var destinationDocumentStream = new FileStream(outputPdfPath, FileMode.Create))
{
var pdfConcat = new PdfConcatenate(destinationDocumentStream);
var pdfReader = new PdfReader(sourceDocumentStream1);
var pages = new List<int>();
for (int i = 0; i < pdfReader.NumberOfPages; i++)
{
pages.Add(i);
}
pdfReader.SelectPages(pages);
pdfConcat.AddPages(pdfReader);
pdfReader = new PdfReader(sourceDocumentStream2);
pages = new List<int>();
for (int i = 0; i < pdfReader.NumberOfPages; i++)
{
pages.Add(i);
}
pdfReader.SelectPages(pages);
pdfConcat.AddPages(pdfReader);
pdfReader.Close();
pdfConcat.Close();
}
}
}
}

I've tried this code, and it works for me, but don't forget to do some validations of the number of pages and existence of the paths you use
here is the code:
private static void AppendToDocument(string sourcePdfPath, string outputPdfPath, List<int> neededPages)
{
var sourceDocumentStream = new FileStream(sourcePdfPath, FileMode.Open);
var destinationDocumentStream = new FileStream(outputPdfPath, FileMode.Create);
var pdfConcat = new PdfConcatenate(destinationDocumentStream);
var pdfReader = new PdfReader(sourceDocumentStream);
pdfReader.SelectPages(neededPages);
pdfConcat.AddPages(pdfReader);
pdfReader.Close();
pdfConcat.Close();
}

You could use something like this, where src is the IEnumerable<string> of input pdf filenames. Just make sure that your existing pdf file is one of those sources.
The PdfConcatenate class is in the latest iTextSharp release.
var result = "combined.pdf";
var fs = new FileStream(result, FileMode.Create);
var conc = new PdfConcatenate(fs, true);
foreach(var s in src) {
var r = new PdfReader(s);
conc.AddPages(r);
}
conc.Close();

PdfCopy is intended for use with an empty Document. You should add everything you want, one page at a time.
The alternative is to use PdfStamper.InsertPage(pageNum, rectangle) and then draw a PdfImportedPage onto that new page.
Note that PdfImportedPage only includes the page contents, not the annotations or doc-level information ("document structure", doc-level javascripts, etc) that page may have originally used... unless you use one with PdfCopy.
A Stamper would probably be more efficient and use less code, but PdfCopy will import all the page-level info, not just the page's contents.
This might be important, it might not. It depends on what page you're trying to import.

Had to even out the page count with a multiple of 4:
private static void AppendToDocument(string sourcePdfPath)
{
var tempFileLocation = Path.GetTempFileName();
var bytes = File.ReadAllBytes(sourcePdfPath);
using (var reader = new PdfReader(bytes))
{
var numberofPages = reader.NumberOfPages;
var modPages = (numberofPages % 4);
var pages = modPages == 0 ? 0 : 4 - modPages;
if (pages == 0)
return;
using (var fileStream = new FileStream(tempFileLocation, FileMode.Create, FileAccess.Write))
{
using (var stamper = new PdfStamper(reader, fileStream))
{
var rectangle = reader.GetPageSize(1);
for (var i = 1; i <= pages; i++)
stamper.InsertPage(numberofPages + i, rectangle);
}
}
}
File.Delete(sourcePdfPath);
File.Move(tempFileLocation, sourcePdfPath);
}

I know I'm really late to the part here, but I mixed a bit of the two best answers and created a method if anyone needs it that adds a list of source PDF documents to a single document using itextsharp.
private static void appendToDocument(List<string> sourcePDFList, string outputPdfPath)
{
//Output document name and creation
FileStream destinationDocumentStream = new FileStream(outputPdfPath, FileMode.Create);
//Object to concat source pdf's to output pdf
PdfConcatenate pdfConcat = new PdfConcatenate(destinationDocumentStream);
//For each source pdf in list...
foreach (string sourcePdfPath in sourcePDFList)
{
//If file exists...
if (File.Exists(sourcePdfPath))
{
//Open the document
FileStream sourceDocumentStream = new FileStream(sourcePdfPath, FileMode.Open);
//Read the document
PdfReader pdfReader = new PdfReader(sourceDocumentStream);
//Create an int list
List<int> pages = new List<int>();
//for each page in pdfReader
for (int i = 1; i < pdfReader.NumberOfPages + 1; i++)
{
//Add that page to the list
pages.Add(i);
}
//Add that page to the pages to add to ouput document
pdfReader.SelectPages(pages);
//Add pages to output page
pdfConcat.AddPages(pdfReader);
//Close reader
pdfReader.Close();
}
}
//Close pdfconcat
pdfConcat.Close();
}

ITextSharp insert text to an existing pdf

The title sums it all.
I want to add a text to an existing PDF file using iTextSharp, however i can't find how to do it anywhere in the web...
PS: I cannot use PDF forms.

I found a way to do it (dont know if it is the best but it works)
string oldFile = "oldFile.pdf";
string newFile = "newFile.pdf";
// open the reader
PdfReader reader = new PdfReader(oldFile);
Rectangle size = reader.GetPageSizeWithRotation(1);
Document document = new Document(size);
// open the writer
FileStream fs = new FileStream(newFile, FileMode.Create, FileAccess.Write);
PdfWriter writer = PdfWriter.GetInstance(document, fs);
document.Open();
// the pdf content
PdfContentByte cb = writer.DirectContent;
// select the font properties
BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252,BaseFont.NOT_EMBEDDED);
cb.SetColorFill(BaseColor.DARK_GRAY);
cb.SetFontAndSize(bf, 8);
// write the text in the pdf content
cb.BeginText();
string text = "Some random blablablabla...";
// put the alignment and coordinates here
cb.ShowTextAligned(1, text, 520, 640, 0);
cb.EndText();
cb.BeginText();
text = "Other random blabla...";
// put the alignment and coordinates here
cb.ShowTextAligned(2, text, 100, 200, 0);
cb.EndText();
// create the new page and add it to the pdf
PdfImportedPage page = writer.GetImportedPage(reader, 1);
cb.AddTemplate(page, 0, 0);
// close the streams and voilá the file should be changed :)
document.Close();
fs.Close();
writer.Close();
reader.Close();
I hope this can be usefull for someone =) (and post here any errors)

In addition to the excellent answers above, the following shows how to add text to each page of a multi-page document:
using (var reader = new PdfReader(#"C:\Input.pdf"))
{
using (var fileStream = new FileStream(#"C:\Output.pdf", FileMode.Create, FileAccess.Write))
{
var document = new Document(reader.GetPageSizeWithRotation(1));
var writer = PdfWriter.GetInstance(document, fileStream);
document.Open();
for (var i = 1; i <= reader.NumberOfPages; i++)
{
document.NewPage();
var baseFont = BaseFont.CreateFont(BaseFont.HELVETICA_BOLD, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
var importedPage = writer.GetImportedPage(reader, i);
var contentByte = writer.DirectContent;
contentByte.BeginText();
contentByte.SetFontAndSize(baseFont, 12);
var multiLineString = "Hello,\r\nWorld!".Split('\n');
foreach (var line in multiLineString)
{
contentByte.ShowTextAligned(PdfContentByte.ALIGN_LEFT, line, 200, 200, 0);
}
contentByte.EndText();
contentByte.AddTemplate(importedPage, 0, 0);
}
document.Close();
writer.Close();
}
}

This worked for me and includes using OutputStream:
PdfReader reader = new PdfReader(new RandomAccessFileOrArray(Request.MapPath("Template.pdf")), null);
Rectangle size = reader.GetPageSizeWithRotation(1);
using (Stream outStream = Response.OutputStream)
{
Document document = new Document(size);
PdfWriter writer = PdfWriter.GetInstance(document, outStream);
document.Open();
try
{
PdfContentByte cb = writer.DirectContent;
cb.BeginText();
try
{
cb.SetFontAndSize(BaseFont.CreateFont(), 12);
cb.SetTextMatrix(110, 110);
cb.ShowText("aaa");
}
finally
{
cb.EndText();
}
PdfImportedPage page = writer.GetImportedPage(reader, 1);
cb.AddTemplate(page, 0, 0);
}
finally
{
document.Close();
writer.Close();
reader.Close();
}
}

Here is a method that uses stamper and absolute coordinates showed in the different PDF clients (Adobe, FoxIt and etc. )
public static void AddTextToPdf(string inputPdfPath, string outputPdfPath, string textToAdd, System.Drawing.Point point)
{
//variables
string pathin = inputPdfPath;
string pathout = outputPdfPath;
//create PdfReader object to read from the existing document
using (PdfReader reader = new PdfReader(pathin))
//create PdfStamper object to write to get the pages from reader
using (PdfStamper stamper = new PdfStamper(reader, new FileStream(pathout, FileMode.Create)))
{
//select two pages from the original document
reader.SelectPages("1-2");
//gettins the page size in order to substract from the iTextSharp coordinates
var pageSize = reader.GetPageSize(1);
// PdfContentByte from stamper to add content to the pages over the original content
PdfContentByte pbover = stamper.GetOverContent(1);
//add content to the page using ColumnText
Font font = new Font();
font.Size = 45;
//setting up the X and Y coordinates of the document
int x = point.X;
int y = point.Y;
y = (int) (pageSize.Height - y);
ColumnText.ShowTextAligned(pbover, Element.ALIGN_CENTER, new Phrase(textToAdd, font), x, y, 0);
}
}

Here is a method To print over images:
taken from here.
Use a different layer for your text you're putting over the images, and also make sure to use the GetOverContent() method.
string oldFile = "FileWithImages.pdf";
string watermarkedFile = "Layers.pdf";
// Creating watermark on a separate layer
// Creating iTextSharp.text.pdf.PdfReader object to read the Existing PDF Document
PdfReader reader1 = new PdfReader(oldFile);
using (FileStream fs = new FileStream(watermarkedFile, FileMode.Create, FileAccess.Write, FileShare.None))
// Creating iTextSharp.text.pdf.PdfStamper object to write Data from iTextSharp.text.pdf.PdfReader object to FileStream object
using (PdfStamper stamper = new PdfStamper(reader1, fs))
{
// Getting total number of pages of the Existing Document
int pageCount = reader1.NumberOfPages;
// Create New Layer for Watermark
PdfLayer layer = new PdfLayer("Layer", stamper.Writer);
// Loop through each Page
for (int i = 1; i <= pageCount; i++)
{
// Getting the Page Size
Rectangle rect = reader1.GetPageSize(i);
// Get the ContentByte object
PdfContentByte cb = stamper.GetOverContent(i);
// Tell the cb that the next commands should be "bound" to this new layer
cb.BeginLayer(layer);
BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
cb.SetColorFill(BaseColor.RED);
cb.SetFontAndSize(bf, 100);
cb.BeginText();
cb.ShowTextAligned(PdfContentByte.ALIGN_CENTER, "Some random blablablabla...", rect.Width / 2, rect.Height / 2, - 90);
cb.EndText();
// Close the layer
cb.EndLayer();
}
}
