How to write Arabic text using MigraDoc?

I am using ASP for this and I had to generate reports in PDF format and send the file back to clients so they can download it.
I made the reports using MigraDoc library and they were great but after I tried it with Arabic text I found the texts were in LTR and the characters were disjointed so I made this code to test things out
...............
MigraDoc.DocumentObjectModel.Document reportDoc = new MigraDoc.DocumentObjectModel.Document();
reportDoc.Info.Title = "test";
sec = reportDoc.AddSection();
string fileName = "test.pdf";
addformattedText(sec, "العبارة", true);
PdfDocumentRenderer renderer = new PdfDocumentRenderer(true);
renderer.Document = reportDoc;
renderer.RenderDocument();
MemoryStream pdfStream = new MemoryStream();
renderer.PdfDocument.Save(pdfStream);
byte[] bytes = pdfStream.ToArray();
...............
private void addformattedText(Section sec,string text, bool shouldBeBold = false)
{
var tf = sec.AddTextFrame();
var p = tf.AddParagraph(text);
p.Format.Font.Name = "Tahoma";
if (shouldBeBold) p.Format.Font.Bold = true;
}
I get the output like this
I have tried to encode the text and make it a unicode string using this code
private string getEscapedString(string text)
{
if (true || HasArabicCharacters(text))
{
string uString = "";
byte[] utfBytes = Encoding.Unicode.GetBytes(text);
foreach (var u in utfBytes)
{
if (u != 0)
{
uString += String.Format(#"\u{0:x4}", u);
}
}
return uString;
}
else
return text;
}
and get the returned string into a paragraph and save the PDF documents with unicode parameter set to true
But it is all the same.
I can not figure out how to get it done.
The reports were done using MigraDoc 1.50.5147 library.

The problem is Arabic language font have 4 different shap in begging,last,connected and alone, where Pdfsharp and MigraDoc can not recognize which shap to print farther more you need to reverse the character order to solve this you can use AraibcPdfUnicodeGlyphsResharper to help do such work as following:
using PdfSharp.Drawing;
using PdfSharp.Pdf;
using AraibcPdfUnicodeGlyphsResharper;
namespace MigraDocArabic
{
internal class PrintArabicUsingPdfSharp
{
public PrintArabicUsingPdfSharp(string path)
{
PdfDocument document = new PdfDocument();
document.Info.Title = "Created with PDFsharp";
System.Text.Encoding.RegisterProvider(System.Text.CodePagesEncodingProvider.Instance);
// Create an empty page
PdfPage page = document.AddPage();
// Get an XGraphics object for drawing
XGraphics gfx = XGraphics.FromPdfPage(page);
// Create a font
XFont font = new XFont("Arial", 20, XFontStyle.BoldItalic);
var xArabicString = "كتابة اللغة العربية شيئ جميل".ArabicWithFontGlyphsToPfd();
// Draw the text
gfx.DrawString("Hello, World!", font, XBrushes.Black, new XRect(0, 0, page.Width, page.Height), XStringFormats.Center);
gfx.DrawString(xArabicString, font, XBrushes.Black, new XRect(50, 50, page.Width, page.Height), XStringFormats.Center);
// Save the document...
document.Save(path);
}
}
}
Do not Forget the Extension method
By the way this is work with iText7 too
see the image for result
Result

PDFsharp does not support RTL languages yet:
http://www.pdfsharp.net/wiki/PDFsharpFAQ.ashx#Does_PDFsharp_support_for_Arabic_Hebrew_CJK_Chinese_Japanese_Korean_6
You can work around this limitation by reversing the string.
PDFsharp does not support font ligatures yet. You are probably able to work around this limitation by replacing letters with the correct glyph (start, middle, end) depending on the position.

How to set the default font for iText7 / pdfhtml

Various comments are written into a PDF table. The table has one column.
The comments come from an HTML editor from a web application and contain HTML text that is output with pdfhtml.
Examples for comments:
<div> a <b>bold</b> and an <i>italic</i> text.</div>
<div><span style="font-size: 18px">large</span><div><div><span style="font-size: 11px">medium</span><div><div><span style="font-size: 8px">small</span></div>
The whole output should be in Verdana, but some other fonts (AgencyFB) should appear (in the spans of the second example).
The code
public byte[] CreateDoc()
{
using (MemoryStream stream = new MemoryStream())
{
using (PdfWriter writer = new PdfWriter(stream))
{
PdfDocument pdfDoc = new PdfDocument(writer);
Document doc = new Document(pdfDoc, PageSize.A4);
PdfFont font = PdfFontFactory.CreateRegisteredFont("Verdana", PdfEncodings.CP1252, true);
float fontSize = 11f;
Table table = new Table(1);
table.AddCell(new Cell().Add(new Paragraph("no Html").SetFont(font).SetFontSize(fontSize)));
string comment1 = "<div>a <b>bold</b> and an <i>italic</i> text.</div>";
string comment2 = "<div><span style=\"font-size: 18px\">large</span><div><div><span style=\"font-size: 11px\">medium</span><div><div><span style=\"font-size: 8px\">small</span></div>";
InsertHtmlCell(table, font, fontSize, comment1);
InsertHtmlCell(table, font, fontSize, comment2);
doc.Add(table);
doc.Flush();
doc.Close();
pdfDoc.Close();
writer.Close();
}
byte[] buffer = stream.ToArray();
return buffer;
}
}
private void InsertHtmlCell(Table table, PdfFont f, float fontSize, string comment)
{
var cell = new Cell(1, 1);
// Without ConverterProperties, "times" is used
ConverterProperties prop = new ConverterProperties();
prop.SetFontProvider(new DefaultFontProvider(false, false, true));
var elements = HtmlConverter.ConvertToElements(comment, prop).Cast<IBlockElement>();
foreach (var element in elements)
{
// without the following 2 lines always "AgencyFB" is used.
element.SetProperty(Property.FONT, f);
element.SetProperty(Property.FONT_SIZE, new UnitValue(UnitValue.CreatePointValue(fontSize)));
cell.Add(element);
}
table.AddCell(cell);
}
Result:
"bold", "large", "medium" and "small": AgencyFB
"italic": BookAntiqua
But the whole output should be in Verdana. How can I reach this?

You are telling the font provider to load all the system fonts. If you definitely don't need all of them, you can just have a white list of fonts that you want to use. In your case you need to add Verdana Regular, Verdana Bold and Verdana Italic fonts.
This is how you can do that:
FontProvider fontProvider = new DefaultFontProvider(false, false, false);
fontProvider.addFont("C:/Windows/Fonts/verdana.ttf");
fontProvider.addFont("C:/Windows/Fonts/verdanab.ttf"); // Bold
fontProvider.addFont("C:/Windows/Fonts/verdanai.ttf"); // Italic

Arabic in pdf using iTextSharp in c#

I want to create a PDF file with Arabic text content in C#. I'm using iTextSharp to create this. I followed the instruction in http://geekswithblogs.net/JaydPage/archive/2011/11/02/using-itextsharp-to-correctly-display-hebrew--arabic-text-right.aspx. I want to insert the following Arabic sentence in pdf.
تم إبرام هذا العقد في هذا اليوم [●] م الموافق [●] من قبل وبين .
The [●] need to be replaced by dynamic English words. I tried to implement this by using ARIALUNI.TTF [This tutorial link suggested it]. The code is given below.
public void WriteDocument()
{
//Declare a itextSharp document
Document document = new Document(PageSize.A4);
//Create our file stream and bind the writer to the document and the stream
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(#"D:\Test.Pdf", FileMode.Create));
//Open the document for writing
document.Open();
//Add a new page
document.NewPage();
//Reference a Unicode font to be sure that the symbols are present.
BaseFont bfArialUniCode = BaseFont.CreateFont(#"D:\ARIALUNI.TTF", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
//Create a font from the base font
Font font = new Font(bfArialUniCode, 12);
//Use a table so that we can set the text direction
PdfPTable table = new PdfPTable(1);
//Ensure that wrapping is on, otherwise Right to Left text will not display
table.DefaultCell.NoWrap = false;
//Create a regex expression to detect hebrew or arabic code points
const string regex_match_arabic_hebrew = #"[\u0600-\u06FF,\u0590-\u05FF]+";
if (Regex.IsMatch("م الموافق", regex_match_arabic_hebrew, RegexOptions.IgnoreCase))
{
table.RunDirection = PdfWriter.RUN_DIRECTION_RTL;
}
//Create a cell and add text to it
PdfPCell text = new PdfPCell(new Phrase(" : "+"من قبل وبين" + " 2007 " + "م الموافق" + " dsdsdsdsds " + "تم إبرام هذا العقد في هذا اليوم ", font));
//Ensure that wrapping is on, otherwise Right to Left text will not display
text.NoWrap = false;
//Add the cell to the table
table.AddCell(text);
//Add the table to the document
document.Add(table);
//Close the document
document.Close();
//Launch the document if you have a file association set for PDF's
Process AcrobatReader = new Process();
AcrobatReader.StartInfo.FileName = #"D:\Test.Pdf";
AcrobatReader.Start();
}
While calling this function, I got a PDF with some Unicode as given below.
اذه يف دقعلا اذه ماربإ مت dsdsdsdsds قفاوملا م 2007 نيبو لبق نم
مويلا
It is not matching with our hard coded Arabic sentence. Is this a issue of font? Please help me or suggest me any other method to implement the same.

#csharpcoder has the right idea, but his execution is off. He doesn't add the cell to a table, and the table doesn't end up in the document.
void Go()
{
Document doc = new Document(PageSize.LETTER);
string yourPath = "foo/bar/baz.pdf";
using (FileStream os = new FileStream(yourPath, FileMode.Create))
{
PdfWriter.GetInstance(doc, os); // you don't need the return value
doc.Open();
string fontLoc = #"c:\windows\fonts\arialuni.ttf"; // make sure to have the correct path to the font file
BaseFont bf = BaseFont.CreateFont(fontLoc, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
Font f = new Font(bf, 12);
PdfPTable table = new PdfPTable(1); // a table with 1 cell
Phrase text = new Phrase("العقد", f);
PdfPCell cell = new PdfPCell(text);
table.RunDirection = PdfWriter.RUN_DIRECTION_RTL; // can also be set on the cell
table.AddCell(cell);
doc.Add(table);
doc.Close();
}
}
You will probably want to get rid of the cell borders etc, but that information can be found elsewhere on SO or the iText website. iText should be able to handle text that contains both RTL and LTR characters.
EDIT
I think the source problem is actually with how the Arabic text is rendered in Visual Studio and in Firefox (my browser), or alternatively with how the Strings are concatenated. I'm not very familiar with Arabic text editors, but the text seems to come out correctly if we do this:
FYI I had to take a screenshot, because copy-pasting into the browser from VS (and vice versa) messes up the order of the parts of the text.

Right-to-left writing and Arabic ligatures are only supported in ColumnText and PdfPTable!
Try out the below code :
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.EMBEDDED);
Font f = new Font(bf, 12);
//Write some text, the last character is 0x0278 - LATIN SMALL LETTER PHI
Doc.Add(new Phrase("This is a ميسو ɸ", f));
//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;
//Close the PDF
Doc.Close();
}

I hope these notes can help you from other answers:
Use a safe code to achieve your font:
var tahomaFontFile = Path.Combine(
Environment.GetFolderPath(Environment.SpecialFolder.Fonts),
"Tahoma.ttf");
Use BaseFont.IDENTITY_H and BaseFont.EMBEDDED properties.
var tahomaBaseFont = BaseFont.CreateFont(tahomaFontFile,
BaseFont.IDENTITY_H,
BaseFont.EMBEDDED);
var tahomaFont = new Font(tahomaBaseFont, 8, Font.NORMAL);
Use PdfWriter.RUN_DIRECTION_RTL, for both your cell and your table:
var table = new PdfPTable(1)
{
RunDirection = PdfWriter.RUN_DIRECTION_RTL
};
var phrase = new Phrase("تم إبرام هذا العقد في هذا اليوم [●] م الموافق [●] من قبل وبين .",
tahomaFont);
var cell = new PdfPCell(phrase)
{
RunDirection = PdfWriter.RUN_DIRECTION_RTL,
Border = 0,
};

i believe your problem in string structure part, try to use the below code it works fine with me, Good Luck.`
public static void GeneratePDF()
{
//Declare a itextSharp document
Document document = new Document(PageSize.A4);
Random ran = new Random();
string PDFFileName = string.Format(#"C:\Test{0}.Pdf", ran);
//Create our file stream and bind the writer to the document and the stream
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(PDFFileName, FileMode.Create));
//Open the document for writing
document.Open();
//Add a new page
document.NewPage();
var ArialFontFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Fonts), "ARIALUNI.ttf");
//Reference a Unicode font to be sure that the symbols are present.
BaseFont bfArialUniCode = BaseFont.CreateFont(ArialFontFile, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
//Create a font from the base font
Font font = new Font(bfArialUniCode, 12);
//Use a table so that we can set the text direction
var table = new PdfPTable(1)
{
RunDirection = PdfWriter.RUN_DIRECTION_RTL,
};
//Ensure that wrapping is on, otherwise Right to Left text will not display
table.DefaultCell.NoWrap = false;
ContentObject CO = new ContentObject();
CO.Name = "Ahmed Gomaa";
CO.StartDate = DateTime.Now.AddMonths(-5);
CO.EndDate = DateTime.Now.AddMonths(43);
string content = string.Format(" تم إبرام هذا العقد في هذا اليوم من قبل {0} في تاريخ بين {1} و {2}", CO.Name, CO.StartDate, CO.EndDate);
var phrase = new Phrase(content, font);
//var phrase = new Phrase("الحمد لله رب العالمين", font);
//Create a cell and add text to it
PdfPCell text = new PdfPCell(phrase)
{
RunDirection = PdfWriter.RUN_DIRECTION_RTL,
Border = 0
};
//Ensure that wrapping is on, otherwise Right to Left text will not display
text.NoWrap = false;
//Add the cell to the table
table.AddCell(text);
//Add the table to the document
document.Add(table);
//Close the document
document.Close();
//Launch the document if you have a file association set for PDF's
Process AcrobatReader = new Process();
AcrobatReader.StartInfo.FileName = PDFFileName;
AcrobatReader.Start();
}
}
public class ContentObject
{
public string Name { set; get; }
public DateTime StartDate { set; get; }
public DateTime EndDate { set; get; }

Force new lines in text, inserted in existing pdf using iTextSharp

So, I've seen an example for a newly created doc
Rectangle r = new Rectangle(400, 300);
Document doc = new Document(r);
try
{
PdfWriter.GetInstance(doc, new FileStream("C:/Blocks2.pdf", FileMode.Create));
doc.Open();
string text = #"The result can be seen below, which shows the text
having been written to the document but it looks a
mess. ";
text = text.Replace(Environment.NewLine, String.Empty).Replace(" ", String.Empty);
Font brown = new Font(Font.FontFamily.COURIER, 9f, Font.NORMAL, new BaseColor(163, 21, 21));
Font lightblue = new Font(Font.FontFamily.COURIER, 9f, Font.NORMAL, new BaseColor(43, 145, 175));
Font courier = new Font(Font.FontFamily.COURIER, 9f);
Font georgia = FontFactory.GetFont("georgia", 10f);
georgia.Color = BaseColor.GRAY;
Chunk beginning = new Chunk(text, georgia);
Phrase p1 = new Phrase(beginning);
Chunk c1 = new Chunk("You can of course force a newline using \"", georgia);
Chunk c2 = new Chunk(#"\n", brown);
Chunk c3 = new Chunk("\" or ", georgia);
Chunk c4 = new Chunk("Environment", lightblue);
Chunk c5 = new Chunk(".NewLine", courier);
Chunk c6 = new Chunk(", or even ", georgia);
Chunk c7 = new Chunk("Chunk", lightblue);
Chunk c8 = new Chunk(".NEWLINE", courier);
Chunk c9 = new Chunk(" as part of the string you give a chunk.", georgia);
Phrase p2 = new Phrase();
p2.Add(c1);
p2.Add(c2);
p2.Add(c3);
p2.Add(c4);
p2.Add(c5);
p2.Add(c6);
p2.Add(c7);
p2.Add(c8);
p2.Add(c9);
Paragraph p = new Paragraph();
p.Add(p1);
p.Add(p2);
p.Alignment = Element.ALIGN_JUSTIFIED;
doc.Add(p);
}
As you can see, the document is initiated with a rectangle Document doc = new Document(r);
So, the result of this code is gonna be like this
My question is: how do I append text, which will consider page size in an existing document?
Is it possible to add a rectangle with a text in a doc? Or maybe append a newly created document to an existing one?
I realise, that I should probably read iText books, but I'm kind of running out of time and this is the last thing I have to figure out. Is there a clean easy solution, to my question? Thank you
UPDATE:
Sadly, for some reason the solution by Alexis Pigeon doesn't work for me.
I've written
Document doc = new Document();
var writer = PdfWriter.GetInstance(doc, new FileStream("C:/Blocks2.pdf", FileMode.Open));
doc.Open();
and at the end
doc.Add(p); doc.Close()
And no changes are applied to the file, although code runs smoothly.
Something tells me, that this approach is wrong, since I haven't met any code examples, where people would have used Document with and existing pdf file, only creating a new one. Usually it's PDFStamper or PDFWriter.
So, let me rephrase my question: How do I append text to an existing document so that it will fill certain rectangle?

So, after looking around I figured out, that what Im looking for is called "hyphenation". Didnt know this word.
To fit the text in a rectangle area you need to create a table with one cell and invisible borders. I've also encoutered issues with encoding. Here is the code.:
PdfReader pdf = new PdfReader("Test1.pdf");
File.Delete("C:/Blocks.pdf");
PdfStamper stp = new PdfStamper(pdf, new FileStream("C:/Blocks.pdf", FileMode.OpenOrCreate));
var canvas = stp.GetOverContent(1);
PdfPTable table = new PdfPTable(1);
table.SetTotalWidth(new float[] { 100 });
Phrase phrase = new Phrase();
phrase.Hyphenation = new HyphenationAuto("ru", "RU", 2, 2);
var bf = BaseFont.CreateFont("c:/windows/fonts/arialbd.ttf", "Cp1251", BaseFont.EMBEDDED);
phrase.Add(new Chunk("О БОЖЕ ТЫ МОЙ НЕУЖЕЛИ РАБОТАЕТ ЕСЛИ РАБОТАЕТ Я БЫЛ БЫ ТАК СЧАСТЛИВ", new Font(bf, 12)));
PdfPCell cell = new PdfPCell(phrase);
cell.Border = Rectangle.NO_BORDER;
table.AddCell(cell);
table.WriteSelectedRows(0, 1, 200, 200, canvas);
stp.Close();

ItextSharp (Itext) - set custom font for paragraph

I am trying to set custom font to Paragraph, but I can't make it work.
I tried setting .Font= , but it only works size-wise, but it ignores font. Could you please assist?
Paragraph T = new Paragraph(newTempLine);
iTextSharp.text.Font contentFont = iTextSharp.text.FontFactory.GetFont("Webdings", 12, iTextSharp.text.Font.NORMAL);
T.Font = contentFont;
myDocument.Add(T);

Set it in the constructor:
Font contentFont = FontFactory.GetFont(…);
Paragraph para = new Paragraph(newTempLine, contentFont);

Check if below works:
string name = "Century Gothic Bold";
if (!FontFactory.IsRegistered(name))
{
string systemRoot = Environment.GetEnvironmentVariable("SystemRoot");
string path = Path.Combine(systemRoot, "fonts", #"GOTHICB.TTF");
FontFactory.Register(path);
}
var font = FontFactory.GetFont(name, fontSize, textColor);
var paragraph = new Paragraph(text, font);
Phrase phrase = new Phrase(paragraph);
var myPdfCell = new PdfPCell(phrase);
