阿拉伯转换“统一”内容HTML或XML为PDF使用iTextSharp的(Convert arabi

我想很多搜索后，创建我的asp.net MVC3应用报告我发现很多博客文章挂在嘴边ITextSharp我的转换Html/Razor到Pdf我试图解析Razor视图获取PDF作为如下

 public void Render(ViewContext viewContext, TextWriter writer)
    {
        var doc = new Document();

        // associate output with response stream
        var pdfWriter = PdfWriter.GetInstance(doc, viewContext.HttpContext.Response.OutputStream);
        pdfWriter.CloseStream = false;

        viewContext.HttpContext.Response.ContentType = "application/pdf";
        viewContext.HttpContext.Response.ContentEncoding = System.Text.Encoding.UTF8;

        // generate view into string
        var sb = new System.Text.StringBuilder();
        TextWriter tw = new System.IO.StringWriter(sb);
        _result.View.Render(viewContext, tw);
        var resultCache = sb.ToString();

        //Path to our font
        string arialuniTff = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Fonts), "ARIALUNI.TTF");
        //Register the font with iTextSharp
        iTextSharp.text.FontFactory.Register(arialuniTff);

        //Create a new stylesheet
        iTextSharp.text.html.simpleparser.StyleSheet ST = new iTextSharp.text.html.simpleparser.StyleSheet();
        //Set the default body font to our registered font's internal name
        ST.LoadTagStyle(HtmlTags.BODY, HtmlTags.FACE, "Arial Unicode MS");
        //Set the default encoding to support Unicode characters
        ST.LoadTagStyle(HtmlTags.BODY, HtmlTags.ENCODING, BaseFont.IDENTITY_H);


        //Parse our HTML using the stylesheet created above
        List<IElement> list = HTMLWorker.ParseToList(new StringReader(resultCache), ST);
        doc.Open();
        //Loop through each element, don't bother wrapping in P tags
        foreach (var element in list)
        {
            doc.Add(element);
        }

        doc.Close();
        pdfWriter.Close();
    }

该代码的结果是

这是不正确的，阿拉伯语单词应该是“محمد”。所以我需要的是设置文档的方向是从右到左

编辑感谢@Romulus

我做了他的代码一点点改变我刚刚更换添加元素PdfPCell到循环在我的HTML，并设置一些属性

 //Loop through each element, don't bother wrapping in P tags
        foreach (var element in list)
        {
            //Create a cell and add text to it
            //PdfPCell text = new PdfPCell(new Phrase(element.ToString(), f));

            //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);
            if (element is iTextSharp.text.pdf.PdfPTable)
            {
                table = (iTextSharp.text.pdf.PdfPTable)element;
                table.DefaultCell.NoWrap = false;
                table.RunDirection = PdfWriter.RUN_DIRECTION_RTL;
                foreach (PdfPRow row in table.Rows)
                {
                    foreach (PdfPCell cell in row.GetCells())
                    {
                        cell.RunDirection = PdfWriter.RUN_DIRECTION_RTL;
                        cell.NoWrap = false;
                    }
                }
            }

        }

现在的工作对我很好谢谢:)

您需要使用支持RunDirection容器元素，如ColumnText或PdfPCell，然后设置其element.RunDirection = PdfWriter.RUN_DIRECTION_RTL

List<IElement> list = HTMLWorker.ParseToList(new StringReader(resultCache), ST);
doc.Open();

//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;
table.RunDirection = PdfWriter.RUN_DIRECTION_RTL;

//Loop through each element, don't bother wrapping in P tags
foreach (var element in list)
{
    //Create a cell and add text to it
    PdfPCell text = new PdfPCell(new Phrase(element, 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);
doc.Close();
pdfWriter.Close();
