问题描述

我想提出一个report.following是code和sample.I我使用HTML表reports.When我运行成功生成了code的PDF，但阿拉伯语是不是showing.Can你指导我如何我可以嵌入阿拉伯语it.Can修改我的下面code，显示阿拉伯语数据。

  Response.ContentType =应用程序/ PDF
Response.AddHeader（内容处置，附件;文件名= TestPage.pdf）;
Response.Cache.SetCacheability（HttpCacheability.NoCache）;
StringWriter的SW =新的StringWriter（）;
HtmlTextWriter的HW =新的HtmlTextWriter（SW）;
tblid1.RenderControl（HW）;
StringReader SR =新StringReader（sw.ToString（））;
文档pdfDoc =新的文档（PageSize.A4，80F，80F，-2F，35F）;
HTMLWorker的HTMLParser =新HTMLWorker（pdfDoc）;
PdfWriter作家= PdfWriter.GetInstance（pdfDoc，Response.OutputStream）;
pdfDoc.Open（）;
htmlparser.Parse（SR）;
pdfDoc.Close（）;
的Response.Write（pdfDoc）;
到Response.End（）;＆LT;表ID =tblid1=服务器＆GT;＆所述; TR＆GT;   ＆LT; TD＆GT;سلطانالخارج＆LT; / TD＆GT;＆LT; TD＆GT;مسندم＆LT; / TD＆GT;＆LT; / TR＆GT;＆LT; /表＆gt;
 

解决方案

您需要嵌入字体到您的PDF支持阿拉伯语字型。

 字符串字体路径= Environment.GetEnvironmentVariable（SYSTEMROOT）+\\\\ \\\\字体arabtype.ttf
BASEFONT BASEFONT = BaseFont.CreateFont（字体路径，BaseFont.IDENTITY_H，BaseFont.EMBEDDED）;
字体arabicFont =新Font（BASEFONT，10F，Font.NORMAL）;
 

螺纹找到

答： iTextSharp的和阿拉伯字符

修改：这是我如何根据例子我能找到并做到这一点你要完成的任务：

 使用（Web客户端的客户端=新的WebClient（））{
   字符串htmlString = client.DownloadString（URL）;
}FontFactory.Register（C：/windows/fonts/arabtype.TTF）;
风格样式表=新的样式表（）;
style.LoadTagStyle（身体，面子，阿拉伯字体％的％NAME）;
style.LoadTagStyle（身体，编码，BaseFont.IDENTITY_H）;
使用（文档的文档=新的文件（PageSize.A4，80F，80F，-2F，35F））{
  PdfWriter作家= PdfWriter.GetInstance（
    文档，Response.OutputStream
  ）;
  document.Open（）;
  在HTMLWorker.ParseToList的foreach（IElement元素（
      新StringReader（htmlString），样式））
  {
    document.Add（元件）;
  }
}
 

请注意，您将需要确保您注册一个包含阿拉伯语字符的编码​​正确的TTF文件，并​​且你需要与你正在使用的字体的名称，以取代阿拉伯字体％的％NAME，并更换％变量包含您的原始HTML％与实际的HTML。

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>

解决方案

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.
