当我尝试使用 C# 这段代码创建阿拉伯语 PDF 时,生成的 PDF 文件包含离散字符。有什么帮助我无法获得连续字符吗?
//Create our document object
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.NOT_EMBEDDED);
//Create a specific font object
iTextSharp.text.Font f = new iTextSharp.text.Font(bf, 12, iTextSharp.text.Font.NORMAL);
//Write some text, the last character is 0x0278 - LATIN SMALL LETTER PHI
Doc.Add(new Phrase("This is a ميسو ɸ", f));
//Write some more text, the last character is 0x0682 - ARABIC LETTER HAH WITH TWO DOTS VERTICAL ABOVE
Doc.Add(new Phrase("Hello\u0682", f));
//Close the PDF
Doc.Close();
}
仅支持从右到左书写和阿拉伯连字ColumnText
and PdfPTable
!
看看下面的例子:

阅读包含这些示例的书,了解为什么在 Peace.pdf 中并非所有单词都能正确呈现

无论如何,您需要一种知道如何显示阿拉伯字形的字体:
BaseFont bf = BaseFont.CreateFont(ARIALUNI_TFF, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
Font f = new Font(bf, 12);
您现在可以添加阿拉伯文本,例如在表格中:
PdfPCell cell = new PdfPCell();
cell.AddElement(new Phrase("Hello\u0682", f));
cell.RunDirection = PdfWriter.RUN_DIRECTION_RTL;
