我想在C#中创建一个包含阿拉伯文字内容的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。
اذهيفددعلااذهماربإمتdsdsdsdsdsقفاوملام2007نيبولبقنم مويلا
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。

@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。
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复制粘贴到浏览器中(反之亦然)会弄乱文本部分的顺序。

只有ColumnText和PdfPTable支持从右到左书写和阿拉伯语连字!
试用以下代码:
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();
}

我希望这些说明可以帮助您解决其他问题:
使用安全代码来实现您的字体:
var tahomaFontFile = Path.Combine(
Environment.GetFolderPath(Environment.SpecialFolder.Fonts),
"Tahoma.ttf");
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);
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,
};
