C# itext pdf creator Greek fonts not displaying - c#

I am trying to create a pdf which contains greek characters. But it doesn't display them at all. I know its something to do with the font but I can't find out the correct way to print the greek characters.
Here is my code:
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(filename, FileMode.Create));
iTextSharp.text.Font font5 = iTextSharp.text.FontFactory.GetFont(FontFactory.HELVETICA, 10);
document.Add(new Paragraph("User: " + NameTxt.Value));
If NameTxt.Value uses greek characters then is not displayed at all

Try that:
string sylfaenpath = Environment.GetEnvironmentVariable("SystemRoot") + "\\fonts\\sylfaen.ttf";
BaseFont sylfaen = BaseFont.CreateFont(sylfaenpath, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
Font normal = new Font(sylfaen, 10f, Font.NORMAL, BaseColor.BLACK);
document.Add(new Paragraph("User: " + NameTxt.Value, normal));

Font style is not preserved when converting HTML to PDF using ItextSharp

I'm trying to convert HTML to PDF, but the font style isn't being properly applied to the PDF. Below is my code (using itextsharp.dll):
Document document = new Document();
FileStream fs = new FileStream(fileName, FileMode.Create);
PdfWriter.GetInstance(document, fs);
document.Open();
HTMLWorker htmlWorker = new HTMLWorker(document);
string content = radEditorCollector.Content;
if (string.IsNullOrWhiteSpace(content))
{
content = AppConstants.LetterNotConfigured;
}
htmlWorker.Parse(new StringReader(content));
document.Close();
fs.Close();
//Create document list of each debtor
PdfReader pdfReader = new PdfReader(fileName);
readerList.Add(pdfReader);
You can edit your font with pdfStamper. Here is little idea. You can manage with what you need.
PdfReader pdfReader = new PdfReader(fileName);
PdfStamper pdfStamper = new PdfStamper(pdfReader, fs);
PdfContentByte pdfContentByte = pdfStamper.GetOverContent(1);
BaseFont baseFont = BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1250, BaseFont.NOT_EMBEDDED);
pdfContentByte.SetColorFill(BaseColor.BLUE);
pdfContentByte.SetFontAndSize(baseFont, 8);
pdfContentByte.BeginText();
pdfContentByte.ShowTextAligned(PdfContentByte.ALIGN_CENTER, "Here is your settings", 400, 600, 0);
pdfContentByte.EndText();
pdfStamper.Close();
readerList.Add(pdfReader);
Update:
Change only tag settings. Use before close.
pdfStamper.AcroFields.SetFieldProperty("YOUR_TAG", "textfont",
baseFont, null);

getting text from a pdf document itextsharp

i tried using iTextSharp to get the text from a pdf document,
it works great if the pdf file is with english text(latin chars).
If i try to get the text from a pdf doc with cyrillic characters the output is just question marks. Are there some settings to be made, or cyrillic isnt supported?
this is the code for creating the pdf:
string testText = "зззi";
string tmpFile = #"C:\items\test.pdf";
string myFont = #"C:\windows\fonts\verdana.ttf";
iTextSharp.text.Rectangle pgeSize = new iTextSharp.text.Rectangle(595, 792);
iTextSharp.text.Document doc = new iTextSharp.text.Document(pgeSize, 10, 10, 10, 10);
iTextSharp.text.pdf.PdfWriter wrtr;
wrtr = iTextSharp.text.pdf.PdfWriter.GetInstance(doc,
new System.IO.FileStream(tmpFile, System.IO.FileMode.Create));
doc.Open();
doc.NewPage();
iTextSharp.text.pdf.BaseFont bfR;
bfR = BaseFont.CreateFont(myFont, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
iTextSharp.text.BaseColor clrBlack =
new iTextSharp.text.BaseColor(0, 0, 0);
iTextSharp.text.Font fntHead =
new iTextSharp.text.Font(bfR, 34, iTextSharp.text.Font.NORMAL, clrBlack);
iTextSharp.text.Paragraph pgr =
new iTextSharp.text.Paragraph(testText, fntHead);
doc.Add(pgr);
doc.Close();
this is the code for retrieving the text:
PdfReader reader1
= new PdfReader("c:/items/test.pdf");
Console.WriteLine(PdfTextExtractor.GetTextFromPage(reader1, 1, new SimpleTextExtractionStrategy()));
Console.ReadLine();
the output is: ???i
EDIT 2
i managed to read text from the pdf i created, but still cant get the text from a random pdf. How can i check if that pdf provides the required info for text extraction?

ITextsharp not displaying ARABIC data when converting html table data to PDF

I am making a report.following is a code and sample.I am using html table for reports.When I run the code pdf is successfully generated but Arabic is not showing.Can you guide me how can i embed Arabic in it.Can you modify my following code which shows arabic data.
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);
tblid1.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A4, 80f, 80f, -2f, 35f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
<table id="tblid1" runat="server">
<tr>
<td>سلطانالخارج</td>
<td>مسندم</td>
</tr>
</table>
You would need to embed a font into your pdf that supports arabic glyphs.
string fontpath = Environment.GetEnvironmentVariable( "SystemRoot" ) + "\\fonts\\arabtype.ttf";
BaseFont basefont = BaseFont.CreateFont( fontpath, BaseFont.IDENTITY_H, BaseFont.EMBEDDED );
Font arabicFont = new Font( basefont, 10f, Font.NORMAL );
Answer found in thread: Itextsharp and arabic character?
EDIT: This is how I would do it based on the examples I could find and what you're trying to accomplish:
using(WebClient client = new WebClient()) {
string htmlString = client.DownloadString(url);
}
FontFactory.Register("c:/windows/fonts/arabtype.TTF");
StyleSheet style = new StyleSheet();
style.LoadTagStyle("body", "face", "%NAME OF ARABIC FONT%");
style.LoadTagStyle("body", "encoding", BaseFont.IDENTITY_H);
using (Document document = new Document(PageSize.A4, 80f, 80f, -2f, 35f)) {
PdfWriter writer = PdfWriter.GetInstance(
document, Response.OutputStream
);
document.Open();
foreach(IElement element in HTMLWorker.ParseToList(
new StringReader(htmlString), style))
{
document.Add(element);
}
}
Note that you would need to ensure you are registering the correct TTF file that contains the encoding for arabic characters and that you would need to replace %NAME OF ARABIC FONT% with the name of the font you're using, and replace %VARIABLE CONTAINING YOUR RAW HTML% with the actual HTML.
var arialFontPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Fonts), "ARIALUNI.TTF");
FontFactory.Register(arialFontPath);
BaseFont bf = BaseFont.CreateFont(arialFontPath, BaseFont.IDENTITY_H, true);
iTextSharp.text.Font FontAr = new iTextSharp.text.Font(bf);
iTextSharp.text.FontFactory.RegisterDirectory(arialFontPath);
StyleSheet styles = new StyleSheet();
styles.LoadTagStyle(HtmlTags.DIV, HtmlTags.FONTSIZE, "16");
styles.LoadTagStyle(HtmlTags.DIV, HtmlTags.COLOR, "navy");
styles.LoadTagStyle(HtmlTags.DIV, HtmlTags.FONTWEIGHT, "bold");
styles.LoadTagStyle(HtmlTags.P, HtmlTags.INDENT, "30px");
styles.LoadTagStyle(HtmlTags.BODY, HtmlTags.FACE, "Arial Unicode MS");
styles.LoadTagStyle(HtmlTags.BODY, HtmlTags.ENCODING, BaseFont.IDENTITY_H);
List<IElement> htmlarraylist = HTMLWorker.ParseToList(new StringReader(htmlText), styles);
for (int k = 0; k < htmlarraylist.Count; k++)
{
pdfDocument.Add((IElement)htmlarraylist[k]);
}
this piece of code worked for me, arabic language works perfect in this,
just pass your html text to my htmltext Variable..
Hopefully it will work fine.

arabic encoding in itextsharp

When I'm trying this code to create a PDF in Arabic using C#, the generated PDF file contains discrete characters. Any help so I can't get continuous characters?
//Create our document object
Document Doc = new Document(PageSize.LETTER);
//Create our file stream
using (FileStream fs = new FileStream(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "Test.pdf"), FileMode.Create, FileAccess.Write, FileShare.Read))
{
//Bind PDF writer to document and stream
PdfWriter writer = PdfWriter.GetInstance(Doc, fs);
//Open document for writing
Doc.Open();
//Add a page
Doc.NewPage();
//Full path to the Unicode Arial file
string ARIALUNI_TFF = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Fonts), "arabtype.TTF");
//Create a base font object making sure to specify IDENTITY-H
BaseFont bf = BaseFont.CreateFont(ARIALUNI_TFF, BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
//Create a specific font object
iTextSharp.text.Font f = new iTextSharp.text.Font(bf, 12, iTextSharp.text.Font.NORMAL);
//Write some text, the last character is 0x0278 - LATIN SMALL LETTER PHI
Doc.Add(new Phrase("This is a ميسو ɸ", f));
//Write some more text, the last character is 0x0682 - ARABIC LETTER HAH WITH TWO DOTS VERTICAL ABOVE
Doc.Add(new Phrase("Hello\u0682", f));
//Close the PDF
Doc.Close();
}
Right-to-left writing and Arabic ligatures are only supported in ColumnText and PdfPTable!
Take a look at the following examples:
http://itextpdf.com/examples/iia.php?id=205 with result: say_peace.pdf
http://itextpdf.com/examples/iia.php?id=215 with result: peace.pdf
Read the book from which these examples are taken to find out why not all words are rendered correctly in peace.pdf
Search http://tinyurl.com/itextsharpIIA2C11 for the corresponding C# version of these examples.
In any case, you need a font that knows how to display Arabic glyphs:
BaseFont bf = BaseFont.CreateFont(ARIALUNI_TFF, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
Font f = new Font(bf, 12);
You can now add Arabic text, for instance in a table:
PdfPCell cell = new PdfPCell();
cell.AddElement(new Phrase("Hello\u0682", f));
cell.RunDirection = PdfWriter.RUN_DIRECTION_RTL;

Html to pdf some characters are missing (itextsharp)

I want to export gridview to pdf by using the itextsharp library. The problem is that some turkish characters such as İ,ı,Ş,ş etc... are missing in the pdf document. The code used to export the pdf is:
protected void LinkButtonPdf_Click(object sender, EventArgs e)
{
Response.ContentType = "application/pdf";
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.AddHeader("content-disposition", "attachment;filename=FileName.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
System.IO.StringWriter stringWrite = new StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
GridView1.RenderControl(htmlWrite);
StringReader reader = new StringReader(textConvert(stringWrite.ToString()));
Document doc = new Document(PageSize.A4);
HTMLWorker parser = new HTMLWorker(doc);
PdfWriter.GetInstance(doc, Response.OutputStream);
doc.Open();
parser.Parse(reader);
doc.Close();
}
public static string textConvert(string S)
{
if (S == null) { return null; }
try
{
System.Text.Encoding encFrom = System.Text.Encoding.UTF8;
System.Text.Encoding encTo = System.Text.Encoding.UTF8;
string str = S;
Byte[] b = encFrom.GetBytes(str);
return encTo.GetString(b);
}
catch { return null; }
}
Note: when I want to insert characters into the pdf document, the missing characters are shown in it. I insert the characters with this code:
BaseFont bffont = BaseFont.CreateFont("C:\\WINDOWS\\Fonts\\arial.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
Font fontozel = new Font(bffont, 12, Font.NORMAL, new Color(0, 0, 0));
doc.Add(new Paragraph("İİııŞŞşşĞĞğğ", fontozel));
Finaly I think I found the solution,I changed itextsharp source code a little in order to show turkish characters.(turkish character code is cp1254)
I add "public const string CP1254 = "Cp1254";" to [BaseFont.cs] in the source code.
After that I modify the [FactoryProperties.cs].I changed like this;
public Font GetFont(ChainedProperties props)
{
I don't write the whole code.I changed only code below;
------------Default itextsharp code------------------------------------------------------
if (encoding == null)
encoding = BaseFont.WINANSI;
return fontImp.GetFont(face, encoding, true, size, style, color);
-------------modified code--------------------------------------------
encoding = BaseFont.CP1254;
return fontImp.GetFont("C:\\WINDOWS\\Fonts\\arial.ttf", encoding, true, size, style, color);
}
.After I compile new dll ,and missing characters are shown.
No need to change the source code.
Try this:
iTextSharp.text.pdf.BaseFont STF_Helvetica_Turkish = iTextSharp.text.pdf.BaseFont.CreateFont("Helvetica","Cp1254", iTextSharp.text.pdf.BaseFont.NOT_EMBEDDED);
iTextSharp.text.Font fontNormal = new iTextSharp.text.Font(STF_Helvetica_Turkish, 12, iTextSharp.text.Font.NORMAL);
thank you very much all who posted the samples..
i use the below solution from codeproject , and there was the turkish char set problems due to font..
If you use htmlworker you should register font and pass to htmlworker
http://www.codeproject.com/Articles/260470/PDF-reporting-using-ASP-NET-MVC3
StyleSheet styles = new iTextSharp.text.html.simpleparser.StyleSheet();
styles.LoadTagStyle("h3", "size", "5");
styles.LoadTagStyle("td", "size", ".6");
FontFactory.Register("c:\\windows\\fonts\\arial.ttf", "Garamond"); // just give a path of arial.ttf
styles.LoadTagStyle("body", "face", "Garamond");
styles.LoadTagStyle("body", "encoding", "Identity-H");
styles.LoadTagStyle("body", "size", "12pt");
using (var htmlViewReader = new StringReader(htmlText))
{
using (var htmlWorker = new HTMLWorker(pdfDocument, null, styles))
{
htmlWorker.Parse(htmlViewReader);
}
}
I am not familiar with the iTextSharp library; however, you seem to be converting the output of your gridview component to a string and reading from that string to construct your PDF document. You also have a strange conversion from UTF-8 to UTF-8 going on.
From what I can see (given that your GridView is outputting characters correctly) if you are outputting the characters to a string they would be represented as UTF-16 in memory. You probably need to pass this string directly into the PDF library (like how you pass the raw UTF-16 .NET string "İııŞŞşşĞĞğğ" as it is).
You can use:
iTextSharp.text.pdf.BaseFont Vn_Helvetica = iTextSharp.text.pdf.BaseFont.CreateFont(#"C:\Windows\Fonts\arial.ttf", "Identity-H", iTextSharp.text.pdf.BaseFont.EMBEDDED);
iTextSharp.text.Font fontNormal = new iTextSharp.text.Font(Vn_Helvetica, 12, iTextSharp.text.Font.NORMAL);
For Turkish encoding
CultureInfo ci = new CultureInfo("tr-TR");
Encoding enc = Encoding.GetEncoding(ci.TextInfo.ANSICodePage);
If you're outputting HTML, try different DOCTYPE tags at the top of the page.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
Note if using HTML you may need to HTMLEncode the characters.
Server.HTMLEncode()
HttpServerUtility.HtmlEncode()
BaseFont bF = BaseFont.CreateFont("c:\\arial.ttf","windows-1254",true);
Font f = new Font(bF,12f,Font.NORMAL);
Chunk c = new Chunk();
c.Font = f;
c.Append("Turkish characters: ĞÜŞİÖÇ ğüşıöç");
document.Add(c);
In the first line, you may write these instead of "windows-1254". All works:
Cp1254
iso-8859-9
windows-1254
Don't change the source code of the iTextSharp. Define a new style:
var styles = new StyleSheet();
styles.LoadTagStyle(HtmlTags.BODY, HtmlTags.FONTFAMILY, "tahoma");
styles.LoadTagStyle(HtmlTags.BODY, HtmlTags.ENCODING, "Identity-H");
and then pass it to the HTMLWorker.ParseToList method.
i have finally find a soultution for this problem , by this you can print all turkish character.
String htmlText = html.ToString();
Document document = new Document();
string filePath = HostingEnvironment.MapPath("~/Content/Pdf/");
PdfWriter.GetInstance(document, new FileStream(filePath + "\\pdf-"+Name+".pdf", FileMode.Create));
document.Open();
iTextSharp.text.html.simpleparser.HTMLWorker hw = new iTextSharp.text.html.simpleparser.HTMLWorker(document);
FontFactory.Register(Path.Combine(_webHelper.MapPath("~/App_Data/Pdf/arial.ttf")), "Garamond"); // just give a path of arial.ttf
StyleSheet css = new StyleSheet();
css.LoadTagStyle("body", "face", "Garamond");
css.LoadTagStyle("body", "encoding", "Identity-H");
css.LoadTagStyle("body", "size", "12pt");
hw.SetStyleSheet(css);
hw.Parse(new StringReader(htmlText));
I strongly suggest not to change itextsharp source code in order to solve this problem. Have a look at my other comment on the subject: https://stackoverflow.com/a/24587745/1138663
I solved the problem. I can provide my the other solution type...
try
{
BaseFont bf = BaseFont.CreateFont("c:\\windows\\fonts\\calibrib.ttf",
BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
Document document = new Document(PageSize.A4, 25, 25, 30, 30);
PdfWriter writer = PdfWriter.GetInstance(document, fs);
Font f = new Font(bf, 12f, Font.NORMAL);
// Open the document to enable you to write to the document
document.Open();
// Add a simple and wellknown phrase to the document
for (int x = 0; x != 100; x++)
{
document.Add(new Paragraph("Paragraph - This is a test! ÇçĞğİıÖöŞşÜü",f));
}
// Close the document
document.Close();
}
catch(Exception)
{
}
