I am trying to create pdf with multiple pages using iTextSharp
Document document = new Document(PageSize.A4, 2, 2, 10, 10);
private PdfContentByte _pcb;
try
{
PdfWriter writer = PdfWriter.GetInstance(document, output);
document.Open();
document.NewPage();
_pcb = writer.DirectContent;
_pcb.BeginText();
_pcb.ShowTextAligned(PdfContentByte.ALIGN_LEFT, text, x, y, 0);
_pcb.EndText();
writer.Flush();
}
catch(e)
{
}
finally
{
document.Close();
}
This is working fine for me. When I am trying to add a new page on the same document, it is replacing the existing written text with new page and no new page is getting added. Below is the code which is not working.
_pcb.EndText();
writer.Flush();
document.NewPage();
_pcb = writer.DirectContent;
_pcb.BeginText();
_pcb.ShowTextAligned(PdfContentByte.ALIGN_LEFT, text, x, y, 0);
_pcb.EndText();
writer.Flush();
Below is my attempt to clean-up and unify your code. Generally avoid try-catch until you actually have to, you'll often miss some very important errors. (For instance, you're not actually setting the font and size which is required but maybe you just omitted that code.) Also, unless you are writing a very large PDF there's really no reason to flush the buffers, leave that to the OS to do for you when necessary.
When I run the code below I get two pages with text on both pages, does it work for you? (Targeting iTextSharp 5.2.0.0)
var output = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "Output.pdf");
var bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1250, BaseFont.NOT_EMBEDDED);
using (FileStream fs = new FileStream(output, FileMode.Create, FileAccess.Write, FileShare.None)) {
using (Document doc = new Document(PageSize.A4, 2, 2, 10, 10)) {
PdfContentByte _pcb;
using (PdfWriter writer = PdfWriter.GetInstance(doc, fs)) {
//Open document for writing
doc.Open();
//Insert page
doc.NewPage();
//Alias to DirectContent
_pcb = writer.DirectContent;
//Set the font and size
_pcb.SetFontAndSize(bf, 12);
//Show some text
_pcb.BeginText();
_pcb.ShowTextAligned(PdfContentByte.ALIGN_LEFT, "Page 1", 40, 600, 0);
_pcb.EndText();
//Insert a new page
doc.NewPage();
//Re-set font and size
_pcb.SetFontAndSize(bf, 12);
//Show more text on page 2
_pcb.BeginText();
_pcb.ShowTextAligned(PdfContentByte.ALIGN_LEFT, "Page 2", 100, 400, 0);
_pcb.EndText();
doc.Close();
}
}
}
Why do you use the DirectContent? If you just want to create a PDF from scratch, just add content to the Document.
try
{
iTextSharp.text.Document doc = new iTextSharp.text.Document();
PdfWriter.GetInstance(doc, new FileStream("HelloWorld.pdf", FileMode.Create));
doc.Open();
doc.Add(new Paragraph("Hello World!"));
doc.NewPage();
doc.Add(new Paragraph("Hello World on a new page!"));
}
catch (Exception ex)
{
}
finally
{
doc.Close();
}
Below Code is working
string str = "Page1Page1Page1Page1Page1Page1Page1Page1Page1Page1";
string str2 = "Page2Page2Page2Page2Page2Page2Page2Page2Page2Page2";
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
using (var htmlWorker = new HTMLWokExtend(pdfDoc))
{
using (var sr = new StringReader(str))
{
htmlWorker.Parse(sr);
}
}
pdfDoc.NewPage();
using (var htmlWorker = new HTMLWokExtend(pdfDoc))
{
using (var sr = new StringReader(str2))
{
htmlWorker.Parse(sr);
}
}
pdfDoc.Close();
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;" +
"filename=Proforma_Invoice.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Write(pdfDoc);
Response.End();
You can populate string from HTML body using below function
private string populatebody()
{
string body="";
using (StreamReader reader = new StreamReader(Server.MapPath("~/Dir/Page.html")))
{
body = reader.ReadToEnd();
}
body = body.Replace("{Content in htmlpage}", "Your Content");
return body
}
And then return this body to string in upper code.
You can manipulate with this code as per your requirement.
Below is HTMLWokExtend Class:
public class HTMLWokExtend : HTMLWorker
{
LineSeparator line = new LineSeparator(1f, 90f, BaseColor.GRAY, Element.ALIGN_CENTER, -12);
public HTMLWokExtend(IDocListener document) : base(document)
{
}
public override void StartElement(string tag, IDictionary<string, string> str)
{
if (tag.Equals("hrline"))
document.Add(new Chunk(line));
else
base.StartElement(tag, str);
}
}

I have been trying to add an image to all pages using iTextSharp.
According to this web page I need to look into the PdfPageEventHelper of iTextSharp.
It provides a method called OnEndPage that allows such things.
Basically, treat the image as being in the header or footer of the document, and use absolute positioning to put it where you want, instead of just in the flow of the page content.
The below code response with error :
Cannot access a non-static member of outer type 'System.Web.UI.Page'
via nested type 'PrintToPdf._events'
On :
PdfPCell cell2 = new PdfPCell(Image.GetInstance(Server.MapPath(imagepath)));
Is there any way to insert the image in the same way in all pages?
Can you help me ?
Thank you in advance.

I looked into iTextSharp and SharpPDF and Report.Net as well as PDFSharp.
None of these open source projects have good documentation OR do not work with VS 2012.
Does anyone have a recommended solution or can show me the documentation?

You can always just create an html page and then convert that to pdf using wkhtmltopdf. This has the benefit of you not having to construct the pdf with a library such as iText. You just make a text file (html) and then pass it to the wkhtmltopdf executable.
See Calling wkhtmltopdf to generate PDF from HTML for more info.
i am trying to export my HTML page to PDF using iTextSharp lib. firstly i am trying to print table which is in my Aspx page.PDF is created successfully but there nothing in PDF.
i am using this code below :
protected void btnExportToPdf_Click(object sender, EventArgs e)
{
btnExportToPdf.Visible = false;
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=TestPage.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
exportTable.RenderControl(hw);
//this.Page.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End(); }
Now I'm not too seasoned, but the problem to me looks like you are never actually writing the strings to the file. I see a few different string objects you initialize, and I see you adding the HTML to it, but I never see you actually write them to the PDF. This is my usual process for parsing HTML to PDF, maybe you can look at it, and see what you are missing.
System.Text.StringBuilder store = new System.Text.StringBuilder();
string line;
while ((line = htmlReader.ReadLine()) != null)
{
store.Append(line + Environment.NewLine);
}
string html = store.ToString();
FileStream stream = new FileStream(newFileName, FileMode.Create, FileAccess.Write);
Document document = new Document(PageSize.LETTER, 15, 15, 35, 25);
PdfWriter writer = PdfWriter.GetInstance(document, stream);
document.Open();
System.Collections.Generic.List<IElement> htmlarraylist = new List<IElement>(HTMLWorker.ParseToList(new StringReader(html), new StyleSheet()));
foreach (IElement element in htmlarraylist)
{
document.Add(element);
}
document.Close();
That was what jumped out to me at least, was the fact that it doesn't look like you actually write the generated text to the PDF. I hope this helps.
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();
}
}
