使用c＃中的iTextSharp的pdf阿拉伯语

我想在C＃中创建一个包含阿拉伯文本内容的PDF文件。 我正在使用iTextSharp来创建它。 我按照http://geekswithblogs.net/JaydPage/archive/2011/11/02/using-itextsharp-to-correctly-display-hebrew–arabic-text-right.aspx中的说明进行操作。 我想在pdf中插入以下阿拉伯语句子。

تمإبرامهذاالعقدفيههااليوم[●]مالموافق[●]منقبلوبين。

[●]需要用动态英语单词代替。 我尝试使用ARIALUNI.TTF实现这一点[本教程链接建议]。 代码如下。

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(); } 

在调用此函数时，我得到了一个带有一些Unicode的PDF，如下所示。

اذهيفدقعلااذهماربإمتdsdsdsdsdsقفاوملام2007نيبولبقنممويلا

它与我们的硬编码阿拉伯语句子不匹配。 这是字体问题吗？ 请帮助我或建议我实施相同的任何其他方法。

Answer 1

@csharpcoder有正确的想法，但他的执行是关闭的。 他没有将单元格添加到表格中，并且表格不会在文档中结束。

 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(); } } 

你可能想要摆脱细胞边界等，但这些信息可以在SO或iText网站的其他地方找到。 iText应该能够处理包含RTL和LTR字符的文本。

编辑

我认为源问题实际上是在Visual Studio和Firefox（我的浏览器）中如何呈现阿拉伯语文本，或者是如何连接字符串。 我对阿拉伯语文本编辑器不太熟悉，但如果我们这样做，文本似乎正确：

仅供参考我必须截取屏幕截图，因为从VS复制粘贴到浏览器（反之亦然）会弄乱文本部分的顺序。

只有ColumnText和PdfPTable支持从右到左的书写和阿拉伯语连字！

试试下面的代码：

  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(); } 

Answer 3

我希望这些笔记可以帮助您解决其他问题：

1. 使用安全代码来实现您的字体：

    var tahomaFontFile = Path.Combine( Environment.GetFolderPath(Environment.SpecialFolder.Fonts), "Tahoma.ttf"); 

2. 使用BaseFont.IDENTITY_H和BaseFont.EMBEDDED属性。

    var tahomaBaseFont = BaseFont.CreateFont(tahomaFontFile, BaseFont.IDENTITY_H, BaseFont.EMBEDDED); var tahomaFont = new Font(tahomaBaseFont, 8, Font.NORMAL); 

3. 对您的单元格和表格使用PdfWriter.RUN_DIRECTION_RTL ：

    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, }; 

Answer 4

我相信你在字符串结构部分的问题，尝试使用下面的代码，它对我很好，祝你好运.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; } }
