在iTextSharp中反转从右到左（双向）语言的字符串 [英] Reversing Strings in Right To Left (BiDirectional) Languages in iTextSharp

问题描述

我正在使用iTextSharp（C＃iText端口）从text / html创建pdf。我的大多数文本都是希伯来语，一种从右到左的语言。

I'm using iTextSharp( C# iText port) to create pdfs from text/html. Most of my text is in Hebrew, a Right-To-Left language.

我的问题是PDF显示反向RTL语言，所以我需要在一种只能反转RTL文本而不用英语反转任何数字或文本的方法。
据我所知，fribidi允许在linux上执行此操作，但我找不到针对此问题的任何解决方案。

My problem is that PDFs show RTL langauge in reverse, so I need to reverse my strings in a way that would only reverse the RTL text without reversing any numbers or text in English. It is my understanding that fribidi allows doing that on linux, but I couldn't find any solutions for this problem for Windows.

我欢迎任何建议，包括自动执行此操作的iTextSharp的替代方法（如果存在）。

I would welcome any suggestions, including an alternative to iTextSharp that would do this automatically (if one exists).

推荐答案

通过正确使用iTextSharp显示RTL文本：

To show RTL texts by using iTextSharp correctly:

• 您需要将字体的编码设置为 BaseFont.IDENTITY_H


• 然后你必须使用支持 RunDirection 的容器元素，例如 PdfPCell ， ColumnText 等，现在你可以设置他们的元素.RunDirection = PdfWriter.RUN_DIRECTION_RTL ;

• You need to set the font's encoding to BaseFont.IDENTITY_H
• Then you have to use container elements which support RunDirection, such as PdfPCell, ColumnText, etc. and now you can set their element.RunDirection = PdfWriter.RUN_DIRECTION_RTL;
