使用iTextSharp为不同的语言生成pdf

本文关键字:语言生成 pdf iTextSharp 使用 | 更新日期: 2023-09-27 18:18:33

我已经尝试了不同的选项,但它没有工作。该代码为英文生成pdf,但不能为其他语言工作。

using (var ms = new MemoryStream())
            {
                // Create an iTextSharp Document which is an abstraction of a PDF but **NOT** a PDF
                var doc = new Document();
                {
                    // Create a writer that's bound to our PDF abstraction and our stream
                    var writer = PdfWriter.GetInstance(doc, ms);
                    {
                        // Open the document for writing
                        doc.Open();
                        string finalHtml = string.Empty;
                        // Read your html by database or file here and store it into finalHtml e.g. a string
                        // XMLWorker also reads from a TextReader and not directly from a string
                        using (var srHtml = new StringReader(sHtmlText))
                        {
                            // Parse the HTML
                            iTextSharp.tool.xml.XMLWorkerHelper.GetInstance().ParseXHtml(writer, doc, srHtml);
                        }                            
                        doc.Close();
                    }
                }
                // After all of the PDF "stuff" above is done and closed but **before** we
                // close the MemoryStream, grab all of the active bytes from the stream
                return new PDFFormFillerResult(ms, PDFFormFillerResultType.Success, string.Empty);
                //bytes = ms.ToArray();
            }

使用iTextSharp为不同的语言生成pdf

我们不得不购买另一个能够理解UNICODE字符的第三方工具

我能够创建英语和日语的多语言PDF。实现这一目标的先决条件1. 要有合适的字体,支持您计划使用的语言。2. 从iTextSharp实现IFontProvider接口,并注册您将使用的多语言字体。

如果你遵循这两个步骤,你可以创建多语言的PDF。

代码示例:

public class smartUIFontProvider: IFontProvider
    {
      public Font GetFont(string fontname, string encoding, bool embedded, float size, int style, BaseColor color)
        {
            string myFont = @"C:'Tasks'Projects'SampleProject'iTextDemo_PDF'SmartFontUI'SmartFontUI.otf";
            iTextSharp.text.pdf.BaseFont bfR;
            bfR = iTextSharp.text.pdf.BaseFont.CreateFont(myFont,
              iTextSharp.text.pdf.BaseFont.IDENTITY_H,
              iTextSharp.text.pdf.BaseFont.EMBEDDED);
            iTextSharp.text.BaseColor clrBlack =
               new iTextSharp.text.BaseColor(0, 0, 0);
            iTextSharp.text.Font fntHead =
              new iTextSharp.text.Font(bfR, 12, iTextSharp.text.Font.NORMAL, clrBlack);
            return fntHead;
        }
       public bool IsRegistered(string fontname)
        {
            return true;
        }
    }

            var fileName = "resources''test_" + System.DateTime.Now.ToString("ddMMyyyy_hhmm") + ".pdf";
            var testFile = Path.Combine(System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location), fileName);
            MemoryStream ms = new MemoryStream();
            // step 2
            using (var writer = PdfWriter.GetInstance(document, ms))
