iTextSharp – Simplify Your HTML to PDF Creation

with 183 comments

Update: A second version that works in .NET 2.0 has been included at the end of this post.

If you’ve ever had to generate PDFs on the fly then you may have run into iTextSharp, which is a port of iText for C#. It isn’t as straight forward as some people might like, but it is certainly a powerful tool once you figure it out.

Normally, if you wanted to take some HTML and turn it into a PDF you would write a lot of extra code to recreate the document in PDF format, but lucky for all of us, iTextSharp also supports HTML. Again, it isn’t exactly straight forward, but to help I wrote a quick wrapper today to help with the process.

HtmlToPdfBuilder allows you to build a PDF using HTML and hides the complexities of working with iTextSharp. You still need iTextSharp to get this project to run, so make sure to include it.

To start, create a new HtmlToPdfBuilder object. As part of the constructor you’ll need to set the document size. It’s actually a Rectangle, but iTextSharp has predefined sizes already available in the PageSize class (constants)

//Page sizes are found in iTextSharp.text.PageSize
HtmlToPdfBuilder builder = new HtmlToPdfBuilder(PageSize.LETTER);

After you have the builder you can add as many pages as you would like using the .AddPage() method. You can also access each of the pages by their index on the builder you create.

HtmlPdfPage first = builder.AddPage();
//also found at builder[0]

HtmlPdfPage second = builder.AddPage();

Once you’ve added your pages you can start adding your HTML with .AppendHtml().

first.AppendHtml("<h1>Hello World</h1>");

//you can also use params for formatting
second.AppendHtml("<h1>{0}</h1><span>{0}</span>", "Hello Second Page", "Another Param");

Next, you’re going to want to apply some styles to your PDF document, you can use a couple methods. First, the .AddStyle() let’s you add a single style to your page. The first parameter is the selector, such as "H1" or ".totals", the second parameter is a single line of CSS such as "color:#F00;font-weight:bold;".

There is also a method called .ImportStylesheet() that accepts an absolute path (not relative) to a stylesheet and adds all of the styles it finds. I was pretty pleased with the method because I was able to do the entire thing with a single Regular Expression.

//add individual styles
builder.AddStyle("H1", "color:#F00");
builder.AddStyle("p", "font-weight:bold;text-decoration:underline;");

//import an entire sheet
builder.ImportStylesheet("c:\\stylesheets\\pdf.css");

It’s worth mentioning that all of my efforts to set heights, widths, paddings and margins didn’t go so well. I’m not sure what the rules are when it comes to that part so be warned.

Finally, you’re ready to save your document. Use the .RenderPdf() method to get the bytes of your PDF.

byte[] file = builder.RenderPdf();
File.WriteAllBytes("c:\\output\\final.pdf", file);

If you’ve worked with iTextSharp before, or you want a little more control over the rendering process, the builder has two events named BeforeRender and AfterRender that give you access to the iTextSharp classes PdfWriter and Document.

Hopefully, this helps simplify working with HTML and PDFs with iTextSharp. Share your thoughts or suggestions!

Source Code

Download HtmlToPdfBuilder.cs

.

Below is a test version for .NET 2.0 – Please let me know if you discover any bugs. Since I am using Visual Studio 2008 I’m not always aware when there is code that won’t work in previous versions.

Download HtmlToPdfBuilder.cs (for .NET 2.0)

Don’t forget, you still need to download iTextSharp and add it as a reference in your project.

    • Peter, great post i try now using your code and it work great, i did not read the code just use him.
      i have some problems with some fonts.
      i know how to use the itextsharp.
      can you tell me what font the code support ?

      dose the code can build tables ?

      Thanks.

    • I am trying to compile the class but it is giving me the error:

      expected ; )

      where public event RenderEvent BeforeRender = (writer, document) => { };

      Any ideas?

  3. This indeed is a very useful post…and I totally have to agree with you that itextsharp is a powerful yet terribly documented tool.
    Therefore I’m hoping you can help me with the following.

    I want to create a PDF with say 10 pages.
    The first 5 pages have background image X and the other 5 have background image Y (the image may vary).

    Is it possible with the HTML builder to do this and by defining the background image does that also mean the images arent inserted individually so the PDF doesnt get too large?

    AND do you perhaps have a code example?

    btw I made a first non-HTML builder attempt here, but I got stuck: http://forums.asp.net/p/1426760/3184974.aspx

    • Peter, I’ll check it out – I wasn’t having much luck with setting backgrounds to elements, but I’m willing to bet there is at least some way to do it.

      There is the BeforeRender and AfterRender events that you might be able to link into to make changes to the background (using the PdfWriter and Document).

      I’ll let you know what I find out.

      • Ow, and one more thing 🙂

        Im generating images on the fly,not stored on disk, can I also insert those?

        My code looks like this:
        Dim imgOutput As New Bitmap(400, 40, PixelFormat.Format32bppArgb)
        Dim g As Graphics = Graphics.FromImage(imgOutput)
        g.Clear(Color.White)
        g.DrawString(“testbarcode”, New Font(“Free 3 of 9 Extended”, 20, FontStyle.Regular), SystemBrushes.WindowText, New PointF(0, 0))

        Thanks for your effort!!

        May 27, 2009 at 2:30 pm

      • Peter, there is a way of adding background to anything and that is with the pdfStamper. I use it to GetOverContent method in the class and also the GetUnderContent with is what I use for background.

        Check it out you will find it useful.

  4. Hi, im writing a page in visual basic.net, is there a vb version of this class? This will definitely help, i just want to import all my css files to the itextsharp. I also tried to convert the “import css” method and paste it in my code… still it cant read my styles.. is there a way we can apply css styles in itextsharp the normal way? like we are doing in the usual markup?

    Thanks in advance,

        Anyone who uses it might want to compare it to the C# version to make sure all of the > < brackets came through (notice at the top for constant DOCUMENT_HTML_START)

        HeadingLine 1Line 2Line 3Line 4

        I have this html string… When I render it on the web its exactly the way is scripted. But when I generate the PDF It genereates it with spaces.

        Any clue y it has so much of space between lines…

        Thanks

    • You are able to apply inline styles when you use the AppendHtml commands.

      document.AppendHtml(“<h1 style=’color:#f00′ >Some text</h1>”);

  5. Peter, I’ve looked into this some and I haven’t found any solutions just yet.

    It seems at first glance that the html parser in iTextSharp just doesn’t use the property.

    webdev_hb

    May 29, 2009 at 9:57 pm

    • mmm…shame.
      But I’ve been looking around in the meantime as well. I think the general iTextsharp support is terrible! My questions are never answered!
      I’ve now switched to PDFsharp, it provides more options and has a much more active forum!
      Not sure if the HTML creation as you have so well demonstrated here is supported but I’ve put my faith there!
      Thanks for your effort!

    • I’m not sure about that – you might be able to use something like …

      <table border=’1′ >… etc…

      I don’t think that the iTextSharp HTML parser is as good as I expected. I’ve been working on my own version of it lately, but I don’t see myself finished for a while.

    • There are two events on the HtmlToPdfBuilder class called BeforeRender and AfterRender. You should be able to do something like…

      HtmlToPdfBuilder pdf = new HtmlToPdfBuilder();
      pdf.BeforeRender += new RenderEvent(HandleBeforeRender);

      //elsewhere in your code
      void HandleBeforeRender(iTextSharp.text.pdf.PdfWriter writer, Document document) {
      //etc…

    Can you let me know why and how to fix it? thanks

    June 30, 2009 at 2:14 pm

    • If you don’t have a reference to System.Data.Linq in your project then you won’t have access to the .AsEnumerable() method.

      You might be able to rewrite that function to not require Linq, but that is most likely your issue.

      webdev_hb

      June 30, 2009 at 2:23 pm

      • Thanks. I included System.Data.Linq. However this line keeps giving me error

        public event RenderEvent BeforeRender = (writer, document) => { };

        Error message says ) expected

        Can you advise again? Thanks so much

        xun

        June 30, 2009 at 3:31 pm

  11. Are you using .NET 2.0?

    I think you should use …

    public event RenderEvent BeginRender = delegate(PdfWriter writer, Document document) { };

    Probably not the best way to do this, but it should get you going.

  12. xun, please leave a comment and fill out the e-mail address and I’ll e-mail you directly so I can help you.

    My best guess is that you don’t have the System.Data.Linq namespace added to the top of your file, but that’s just a guess.

    I’ll e-mail you once I get your address. Thanks!

    • Hi there,
      I was getting the same problems as Xun, I need to try and run this in a 2.0 project. Any chance you could mail me whatever you sent him please?
      Thanks

      MJ

      July 17, 2009 at 6:58 am

      • I never heard back from Xun so I couldn’t help him.

        I’m thinking that the problem is that in the code I wrote an event like this…

        public event RenderEvent BeforeRender = (writer, document) => { };

        I was thinking I’d just define it like that so it wouldn’t even be null (not sure why I thought that made sense)

        In any case, you could set that to null and then find the places where that event is called and change it so that it checks to see if it is null before it call the method

        if (this.BeforeRender is RenderEvent) {

  15. Hi,

    i have some trouble adding images from a relative path. i’ve a webpage which includes images an stylesheets just by using “includes/style.css” or “images/image1.jpg”. But this doesn’t work because the HTMLBuilder always tries to read out from an absolute path like “c:\includes/style.css”. Any idea how to fix it?

    Thanks a lot – and up to this little problem great work!! 🙂

    • That is an interesting problem, I’m not sure I have a great solution for you though…

      You might try using a regular expression similar to…

      src=\”(?[^\”]+\” (untested…)

      That will find all of your URLs. At that point, you could extract the path out and use Server.MapPath() to try and convert it.

      After you have your new string, just replace it in the document.

      Heads up, if you’re doing Regex replacements, loop backwards – if you change a string in the middle of looping it messes up all the remaining indexes.

    • It depends on what you’re using, either WebForms or MVC.

      MVC is super-easy, just do a “File” call from your controller and specify the byte array generated as your file to download.

      If you’re using WebForms then it is going to be only slightly more complicated. You’re going to need to write that byte array to the output stream, change the content type and then set the “content-disposition” for your response. That way it will appear as a download.

      Just look up that phrase and you’ll find all the information you need.

      Good luck

    • The basic structure of the document is created for you as in the html, body, head, etc tags. You only need to append the actual HTML you plan to display when you use AppendHtml()

  21. Hi

    I’ve been trying to convert my HTML to PDF since yesterday. We have a third party toolkit which can be used for converting to PDF, but it’s way more trouble than it’s worth.

    So I looked at iTextSharp. Mine works fine, but as soon as there is a table tag in my html I get this error:
    Unable to cast object of type ‘iTextSharp.text.Paragraph’ to type ‘iTextSharp.text.Table’.

    Does anyone have any idea on what needs to be done to get it to work with a table tag?

    Thanks.

    • Can you post some code? Are you using the HTML parser that comes with iTextSharp?

      webdev_hb

      August 5, 2009 at 7:42 am

      • HTML parser that comes with iTextSharp.

        This is what my Test html file looks like:

        Untitled Page

        some text

        some more text

        if you remove the table tags it works, but not with the table tags. As long as I don’t use table tags everything works.

        I’m going to download HtmlToPdfBuilder now to make things a little easier.

        Thanks for the speedy reply 🙂

      • Don’t include the tags like html or body — Just the markup for the document itself.

        August 5, 2009 at 8:05 am

      • I tried that, still get same error. Guess I’ll just have to redo it all without using tables. Getting everything to display as nice a table does will be tricky.

      • Strange, I’ve used tables before and I got them to work. I don’t think you can use things like paragraphs with floats to simulate a table.

        Good luck! If you want to post some code I’ll check it out.

      • aahh… now that I’m using your HtmlToPdfBuilder it works. Although I now have a new problem. It does not export the images and every table cell is now in a new line in the pdf file.

        Any ideas??

        NeCroFire

        August 5, 2009 at 10:07 am

      • I hadn’t used images with my PDFs before, but I gave a suggestion to another visitor how he might be able to load them into the document. It is purely a guess but iTextSharp might want to see an “absolute” path instead of “relative”. If you were to parse the document and switch out the paths it might fix that problem.

        For the table, I’m not sure why you’re having a problem… Are you just doing a simple table like so?

        <table>
        <tr>
        <td>Cell #1</td>
        <td>Cell #2</td>
        </tr>
        </table>

        The iTextSharp HTML Parser isn’t that awesome – I was playing around with making my own but hadn’t gotten that far into it.

        webdev_hb

        August 5, 2009 at 10:13 am

      • Yes, that’s what my table is like.

        I get the images from a web service. I have to send a code through and it returns an image URL. I will see what I can do there.

        What I have is a asp:Repeater that lists information about different vehicles. I only want to export everything that’s in the repeater at that moment to PDF file. Getting this data I can do, it’s teh whole HTML to PDF that won’t work like I’d like it to.

        Anyway, here in South Africa it’s already 17:30. Will check in tomorrow.

    • I’ve noticed what you’re talking about – The HTML parser used by iTextSharp isn’t really as good as it could be. Many styles that adjust the document sizes or positions don’t work at all.

      I had been investigating writing my own parser, but for now I’m using the built in version.

    • I know that many of the styles seem to not be supported by the iTextSharp html parser. I’ve only gotten attributes some styles to actually work (like font-color for example)

    • Thats a good question – I doubt that the iTextSharp HTML parser is going to do well with that but I’ll have to check it out.

      The HTML parser in iTextSharp excludes a lot of styles like height, width, margins, etc… if the style has to do with positioning or sizes, chances are it doesn’t work anyways.

    • If you’re using new lines and tabs then this class isn’t going to help you out very much. You need to use HTML markup to generate your content… so for example…


      HtmlToPdfBuilder builder = new HtmlToPdfBuilder(PageSize.LETTER);
      HtmlPdfPage first = builder.AddPage();
      first.AppendHtml("<p>Some Content</p>");

  33. Great class! however I have a problem with Polish letters (ą, ż, ź, ć, ó, ę, ł). I have the example working well with Polish letters, but It doesn’t work with tables (similarly how wrote “NeCroFire”).

    Is It possible to add the embleded font into Your class?

    It is a code which works with Polish letters

    BaseFont arial = BaseFont.CreateFont(@”C:\WINDOWS\Fonts\arial.ttf”, “iso-8859-2”, BaseFont.EMBEDDED);

    //creation of a document-object
    Document document = new Document();
    XmlDocument xmlDocument = new XmlDocument();
    xmlDocument.Load(“../../Raport/test.html”);
    try
    {
    PdfWriter.GetInstance(document, new FileStream(“generowanyDokument.pdf”, FileMode.Create));

    //header
    document.Add(new Header(Markup.HTML_ATTR_STYLESHEET, string.Empty));
    document.Open();

    //create a parser
    ITextHandler xmlHandler = new ITextHandler(document, new HtmlTagMap(), arial);
    xmlHandler.Parse(xmlDocument);//”generowanyDokument.xml”);
    document.Close();
    }
    catch (Exception e)
    {
    }

    Thanks

  34. Hello,
    Let me thank you first for the great piece of code and having will to share it.
    I am facing stylesheet no-effect issue.
    I used your code as this, my strURL= “http://localhost/Test/Common/UserControls/Lab/HtmltoPDF/HTMLPage.htm”
    its content is

    Test message
    address

    where .addressbook
    {
    width: 600px;
    font: 82% arial,helvetica, “Nimbus Sans L” ,sans-serif;
    border: solid 1px #666;
    margin-left: 30px;
    text-decoration: underline;
    color: #CC0000;
    }

    NOTE: I am unable to get the underline and red color of the font.
    I made changes in..HtmlToPdfBuilder as
    public void ImportStylesheet(string path) {
    //load the file
    string content = “”;
    try
    {
    content = File.ReadAllText(path);
    }
    catch
    {
    WebClient objclient = new WebClient();
    content = objclient.DownloadString(path);
    content= content.Replace(“\n”,””);
    content= content.Replace(“\r”,””);
    content= content.Replace(“P”,””);
    content= content.Replace(“\””,””);
    content = content.Replace(“\t”, “”);
    }

    //use a little regular expression magic
    foreach (Match match in Regex.Matches(content, HtmlToPdfBuilder.REGEX_GET_STYLES)) {
    string selector = match.Groups[HtmlToPdfBuilder.REGEX_GROUP_SELECTOR].Value;
    string style = match.Groups[HtmlToPdfBuilder.REGEX_GROUP_STYLE].Value;
    this.AddStyle(selector, style);
    }

    }

    But still no luck…Infact it is adding the style tags in the document running without any prob but just no effect of style sheet. Will you suggest what might be the reason.

    Final code is here:

    GeneratePDFwithStyleSheet(string strURL)
    {
    string strBodycontent= GetBodyContent(strURL);
    strBodycontent = strBodycontent.Replace(“\n”, “”);
    strBodycontent = strBodycontent.Replace(“\r”, “”);
    string a = “\””;
    strBodycontent = strBodycontent.Replace(a, “‘”);
    strBodycontent = strBodycontent.Replace(“P”, “”);
    strBodycontent = strBodycontent.Replace(“\t”, “”);

    PDFBuilder.HtmlToPdfBuilder builder = new PDFBuilder.HtmlToPdfBuilder(PageSize.LETTER);
    PDFBuilder.HtmlPdfPage first = builder.AddPage();
    first.AppendHtml(strBodycontent);
    //builder.ImportStylesheet(“http://localhost/OnActionC/Common/_assets/css/addressbook.css”);
    builder.ImportStylesheet(@”C:\inetpub\wwwroot\onactionc\Common\_assets\css\addressbook.css”);
    byte[] file = builder.RenderPdf();
    File.WriteAllBytes(@”c:\pdf\Chap084.pdf”, file);
    }

  36. Hello,
    I think I got the solution, the contents of css has
    “” and we need to remove “.” in css contents I used this. now stylesheet is implemented successfully.

    content = content.Replace(“”, “”);
    content = content.Replace(“.”, “”);
    content = content.Substring(3,content.Length-3);

    Thanks once again.

    • Prashanth,

      I’m not really sure about the different character types. It could be a iTextSharp thing since I don’t believe I’m making any changes to the encoding of the text being used.

      September 24, 2009 at 9:34 pm

    • HiPrashanth,
      do you want to say that you could render pdf from html with css stylesheet? For me it is not working 😐
      I use itextsharp.dll 5.0.0 and HtmlToPdfBuilder_2_0.cs . 😕

      Adrian

      November 3, 2010 at 5:55 am

  37. This:

    byte[] file = builder.RenderPdf();
    File.WriteAllBytes(@”c:\\output\\final.pdf”, file);

    Causes this error: “Could not find a part of the path ‘c:\output\final.pdf’.”

    Is there a way to cause this to load in a browser? I don’t need to save anything.

    Thanks…

    • If you’re using ASP.NET MVC then you can simply return the bytes using the controller method “File”

      If not you can always use the Response.OutputStream and write the content directly.

    Could not load type ‘Voucher.Core.PdfBuilder.HtmlToPdfBuilder’ from assembly ‘Voucher.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null’ because the method ‘get_PageSize’ has no implementation (no RVA).

    Where I’ve loaded the PdfBuilder into my own Custom C# Class Library for the application I’m trying to use the PdfBuilder.

  39. Fantastic code this has really helped me to make use of itextsharp using an ajax html editor. I am using it for a mailing application that i am building. Many thanks for sharing this.

    I am looping though a table with a datareader to generate letters is there a way i can continuously append the html to multiple pages then insert a page break after each database record. (hope that makes sense). Any help would be greatly appreciated also how easy would it be to stream the pdf instead of creating a physical file.

  47. the regular expression in the code is wrong. The one in the sorce code do not consider the tag with one letter like “p” or “a”.
    the correct(real magic) one is :
    private const string REGEX_GET_STYLES = @”(?[^\{\s]*\w*(\s\[^\{\s]*)?)\s?\{(?[^\}]*)\}”;

  53. Great post Hugo!

    Has anyone figured out the margin issue? My left and right margins are messed up (the left and right sides of my document are truncated). I tried tweaking the code to force a one inch margin.

    Document document = new Document(this.PageSize, 72, 72, 72, 72);

    But that did not fix anything.

    Another noteworthy tip is to use the Tidy.dll library to cleanup HTML (the HTML I am using comes from an XML transformation that I have not control of). I was getting a ‘no stack’ error on this call

    foreach (var item in (IEnumerable)HTMLWorker.ParseToList(reader, this._Styles)) {

    Once I cleaned up the HTML I was able to at least get the HTML to render. I used this .NET wrapper to call the tidy.dll (http://markbeaton.com/SoftwareInfo.aspx?ID=81a0ecd0-c41c-48da-8a39-f10c8aa3f931)

    • Interesting. What does it tell me if I rotate to landscape, as in the following,

      HtmlToPdfBuilder builder = new HtmlToPdfBuilder(PageSize.LETTER.Rotate());

      …my left and right margins are appearing.

      This leads me suspect it is not a margin issue after all.

      Any suggestions would be appreciated.

      • I was able to get my HTML to render correctly in the portrait orientation.

        The fix was to reduce the width of the tables by 150pt’s (from 680 to 530).

        QN: Is there a less invasive way to reduce the HTML before feeding it into htmltopdfbuilder? Maybe I need to send to produce an HTML image then reduce the image.

        Cheers!

    • try this

      and u can set the margin also by
      document.setmargin(int top,int bottom,int left,int right);

      January 5, 2010 at 6:08 am

      • I had already tried Document document = new Document(this.PageSize.A4, 72, 72, 72, 72); And setmargins has no affect.

        That is why I tried rotating, which at least gives me the left and right side of my document. It is for this reason that I suspect something else is going on. It’s almost as if the

        Below is the snippet that works in landscape:

        HtmlToPdfBuilder builder = new HtmlToPdfBuilder(PageSize.LETTER.Rotate());
        HtmlPdfPage first = builder.AddPage();
        first.AppendHtml(source); // where source is my entire HTML document
        byte[] file = builder.RenderPdf();

        Any suggestions would be appreciated to get the HTML document to convert to portrait.

    • Consider using the InternetExplorer object to capture the rendered HTML.

      SHDocVw.InternetExplorer ie = new SHDocVw.InternetExplorer();
      object Empty = 0;

      object URL = “your URL”;

      // override BeforeNavigate2 event
      ie.BeforeNavigate2 += new
      SHDocVw.DWebBrowserEvents2_BeforeNavigate2EventHandler(
      e.OnBeforeNavigate2);

      ie.Navigate2(ref URL, ref Empty, ref Empty, ref Empty, ref Empty);
      while (ie.Busy) { }

      // source contains the rendered HTML
      string source = ((mshtml.HTMLHtmlElementClass)((mshtml.HTMLDocumentClass)(((SHDocVw.InternetExplorerClass)(ie)).Document)).documentElement).outerHTML;

  55. Great Job Man.
    But A lot of CSS like background-color, background-image etc are not working.
    What should be done?

    Hello

    January 6, 2010 at 6:19 am

  56. In your article you indicate that you can reference a CSS class (.classname) however, when I try it, the css class seems to be ignored upon rendering the PDF.

    Also, there does not seem to be any support for CSS such as: border: solid 1px black; etc….

    Is there a bug in the C# which causes class names and certain CSS elements to be ignored? Or is there simply no current support for some CSS elements?

    Bill Miles

    January 6, 2010 at 11:44 pm

  57. CSS is very limited with iTextSharp or more specifically the HTML parser for it — The HtmlPdfBuilder acts as a wrapper to the HTML support for iTextSharp, but that is about it.

    Since this post is getting so much attention I’ll start looking over any possible ways to fix some of the CSS issues

  59. Although I was able to get HtmlToPdfBuilder to work, I discovered that portions (entire tr tags) of my HTML were getting dropped.

    Without spending too much time, I suspect the issue may or may not be relate to nested table tags.

    HtmlToPdfBuilder builder = new HtmlToPdfBuilder(PageSize.LETTER.Rotate());
    HtmlPdfPage first = builder.AddPage();
    first.AppendHtml(source);
    byte[] file = builder.RenderPdf();

    At this point in my project I had no choice but to fall back on a commercial product (AbcPdf)

  65. Hi,

    I have a requirement to validate if certain html fits on a pdf doc in a single page … Here is what i wrote :

    ——–html
    ======================================================

    Check with document
    0
    0
    562
    56

    <asp:textbox runat="server" id="lblText" textmode="MultiLine" text="Test Headingline 1 xyz xyz xyz xyz line 1 xyz xyz xyz xyz line 1 xyz xyz xyz xyz ” rows = “20” width=”400px”>

    ———- code behind
    private void GeneratePDF()
    {
    try
    {

    // convert the html to pdf //
    byte[] file = ConvertToPDF();

    // check to see if the htmlcontent fits on the pdf //
    GetNumberOfPDFPages(file);

    // not needed, only for verification //
    WriteFileToFileForVerification(file);
    }
    catch (Exception ex)
    {
    lblLabel.Text = ex.Message;
    }
    }

    private byte[] ConvertToPDF()
    {
    Rectangle rect = new Rectangle(int.Parse(TextBox1.Text), int.Parse(TextBox2.Text), int.Parse(TextBox3.Text), int.Parse(TextBox4.Text));
    PDFBuilder.HtmlToPdfBuilder builder = new PDFBuilder.HtmlToPdfBuilder(rect);
    PDFBuilder.HtmlPdfPage NewPage;
    NewPage = builder.AddPage();
    NewPage.AppendHtml(lblText.Text.Trim());

    byte[] file = builder.RenderPdf();

    return file;
    }

    private void GetNumberOfPDFPages(byte[] file)
    {
    PdfReader reader = new PdfReader(file);
    lblPageCount.Text = ” No of Pages in the pdf doc : ” + reader.NumberOfPages;
    }

    private void WriteFileToFileForVerification(byte[] file)
    {
    PdfReader rd = new PdfReader(file);

    File.WriteAllBytes(Server.MapPath(“~”) + “/” + “final.pdf”, file);
    }

    — What the above code will do ———
    What the code above will do is create a pdf and check of the number of pages.. If number of pages in the generated document is more than 1 then we notify the user that the html supplied will not fit.

    — The output ——————-
    The pdf gets generated great, but if you look at the pdf, it leaves a huge space on the top of each page and due to this prints only one line and even though this text should fit in one page creates 4 pages with one line each…

    Can anyone please advice me as to why the big space on the top of each page in the document..

    Thanks for any help in advance…

    builder.AddStyle(“#total”, “font-weight:bold;”);

  68. Your post help me a lot of understanding how to use HTML to build a pdf file. I have a project need to build some pdf files. I want use some flexible way to modify the template using HTML or XML. But the output pdf file must be in CMYK color. Can I generate a CMYK pdf file using HTML convertion? or I should use XML instead? If XML is needed, how do you have any reference/example for me?

  73. To apply border bottom just put the below specified line of code in incell.cs file parameter constructer.

    value = props[“border-bottom-width”];
    float borderbottom = 0;
    if (value != null)
    borderbottom = float.Parse(value, System.Globalization.NumberFormatInfo.InvariantInfo);
    cell.BorderWidthBottom = borderbottom;

    also add below line of code in the insertStyle of the FactoryProperties class

    else if (key.Equals(Markup.CSS_KEY_BORDERWIDTHBOTTOM))
    {
    String ss = prop[key].Trim().ToLower(System.Globalization.CultureInfo.InvariantCulture);
    h[“border-bottom-width”] = ss;
    }

    In your html page add the Style as follows.

    1

    In order to make it work for other style propeties you have to parse the style element in the incell.cs class.

  74. […] Reference from : Hugoware […]

  75. […] If you want to use iTextSharp to convert HTML to PDF, you can start it by reading a very good article “iTextSharp – Simplify Your HTML to PDF Creation” at https://somewebguy.wordpress.com/2009/05/08/itextsharp-simplify-your-html-to-pdf-creation/ […]

  76. This is a great wrapper class for iTextSharp. Is it possible to directly stream the generated PDF to the client browser instead of saving it in the hard drive? If you have a code snippet how to do it, that will be great!!

    Thanks

  77. Hi,
    This article was wonderful and helpful to me but, I can’t get the output from my HTML code. I don’t know why? This component will not consider the ‘style’ attribute for the HTML tags. I have tried using this code snippets. But I was disappointed by seeing the ouput.

    StringBuilder htmlText =
    new StringBuilder(“<table background='c:\\IMG_0806.jpg' style='background-repeat:no-repeat;'");
    htmlText.Append("Karunagara Pandi Software Engineer”);

    HtmlToPdfBuilder builder = new HtmlToPdfBuilder(PageSize.A4);
    HtmlPdfPage first = builder.AddPage();
    first.AppendHtml(htmlText.ToString());

    byte[] fileContent = builder.RenderPdf();
    File.WriteAllBytes(@”C:\PDFImage.pdf”, fileContent);

    Image is not shown…the page… Without using styles alone, how to get the output by adding subsidiary attribute of the tags…..

  78. Hi Hugo.

    Great job.
    But can you give me tips about how to format cells in a table.
    I mean:

    HIPEOPLE
    or
    HIPEOPLE

    does not work:
    the columns are the same size, 50% each.

    I see it works with the ‘colspan’ attribute, but I need ‘width’.

    Any idea?
    Thanks.

    About people looking for headers/footers with itextsharp 5 or later, have a look at this example:

    if (Cache[“pageContent”] == null || (DateTime)Cache[“pageCreateTime”] < expired)
    {
    // Render the page
    System.IO.StringWriter htmlStringWriter = new System.IO.StringWriter();
    Server.Execute(target, htmlStringWriter);

    // Save the page content to the Cache
    Cache["pageContent"] = htmlStringWriter.ToString();
    Cache["pageCreateTime"] = DateTime.Now;

    //Page sizes are found in iTextSharp.text.PageSize
    HtmlToPdfBuilder builder = new HtmlToPdfBuilder(PageSize.LETTER);
    HtmlPdfPage first = builder.AddPage();
    first.AppendHtml(htmlStringWriter.ToString());

    byte[] file = builder.RenderPdf();
    File.WriteAllBytes(Server.MapPath("PDF/Chart.pdf"), file);

    // Output the cached content

    which are the tags supported, which are not? what can it be done?
    I have this in my css file:

    h2
    {
    color: red;
    }
    div.big
    {
    background-color: green;
    }

  86. Hi

    I have made some support for margins for the 4.1.6 version. You can download the files here and replace the files in 4.1.6 source.

    (Get file here)
    https://sourceforge.net/tracker/?func=detail&aid=3102295&group_id=72954&atid=536238

    Then you can do things like this:

    styles.LoadTagStyle(“li”, “style”, “margin-top:0;margin-bottom:0;”);
    styles.LoadTagStyle(“ul”, “style”, “margin-left:10px;margin-top:5;margin-bottom:5;”);
    styles.LoadTagStyle(“ol”, “style”, “margin-left:10px;margin-top:5;margin-bottom:5;”);
    styles.LoadStyle(“phead”, “style”, “font-family: Arial;font-size: 12pt;color:#333333; font-weight:bold;line-height:12pt;margin-top:10;”);

  92. I need to be able to determine the size in bytes of each page in a PDF file. I can get the size of a page in xy cordinates. But I need page size as if that page were stored as a file on disk (size in bytes). Is there a method in ITextSharp that will allow me to get the size of a given page in bytes?

    Thank You!

      Also get this errors:
      ‘PDFBuilder.HtmlToPdfBuilder.PageSize.get’ must declare a body because it is not marked abstract or extern on this line:
      public Rectangle PageSize { get; set; }

      Also i try tu use vb.net class but is not completed and with other errors, anyone got a solution? thanks 😦

      March 31, 2011 at 10:39 am

      • Finally i solve it using a previous version of iText and using a code inside the replays to remove the error i have, now i have another thing, i already have an html on disk so load the Html content of the file on a string, but i get this error:
        Input string was not in a correct format.
        on:
        public virtual void AppendHtml(string content, params object[] values) {
        this._Html.AppendFormat(content, values);
        }
        i guess this is becaus i send all the html of the file in the string maybe?

      • Hi Oliver,

        I have the exact same error. Can you please give me the full details of how you solved it? Do I need to change the code of the HtmlToPdfBuilder class? I need to fix this urgently to fulfill requirements for a project I am working on.

        I tried to compile this in VS 2005 (C#). I first used the latest version of the iTextSharp libraries (5.0.6), and also tried with (4.1.2), but the error remains the same. If you have used a different version, can you please attach the dll or share the dll you used with me?

        Please give me the complete details of how to fix this as I am new to iTextSharp.

        If there’s anyone else who has encountered this and can help me, I will be very grateful to hear from you.

        Many thanks!

        April 8, 2011 at 6:36 am

      • I, like imentioned in this post, the error was raised becuase in the html text you have this characters “{” or “}”, that is a problem for the code because use those characters for something else, my recomendation is replace thos strings before send it to convert to something lile “(” and “)” and your problem is solved 🙂
        anyway i just can’t make the code work for the new version of iText that is the version that solve the problems of apply styles to the pdf file converted 😦

        Oliver

        April 8, 2011 at 8:07 am

  95. Ok, solve it, i hace some “{” and “}” in html code that was crashing this thing….now i have a differente issue with REGEX_GET_STYLES:
    parsing “(?[^\{\s]+\w+(\s\[^\{\s]+)?)\s?\{(?[^\}]*)\}” – Unrecognized grouping construct.
    on:
    public void ImportStylesheet(string path) {
    string content = File.ReadAllText(path);
    foreach (Match match in Regex.Matches(content, HtmlToPdfBuilder.REGEX_GET_STYLES)) {

    any ideas?

  99. Hi,

    I used the above code along with the itextSharp assembly, although i am able to generate the pdf if i pass a string. but the pdf is empty if i pass HTML tags..

    Below is the code i am trying with

    string strCont = “NameAgeCity”;
    HtmlToPdfBuilder builder = new HtmlToPdfBuilder(PageSize.LETTER);
    HtmlPdfPage first = builder.AddPage();
    first.AppendHtml(“strCont”);
    byte[] file = builder.RenderPdf();
    File.WriteAllBytes(“c:\\final2.pdf”, file);

    Please let me know if am missing anything here.

    Thanks,
    Raj
