使用iTextSharp为不同语言生成pdf [英] Generate pdf using iTextSharp for different languages
本文介绍了使用iTextSharp为不同语言生成pdf的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我尝试了不同的选项，但它没有用。该代码为英语生成pdf但不适用于其他语言。
I have tried different options, but it did not work. The code generated pdf for English but does not work for other languages.
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();
}
推荐答案
我能够创建多个语言PDF英文和日文。
实现此
的先决条件1.拥有支持您计划使用的语言的相应Font。
2.从iTextSharp实施IFontProvider界面并注册您将使用的多语言字体。
I was able to create multi language PDF in English and Japanese. The prerequisite for achieving this 1. To have appropriate Font which supports the languages you are planning to use. 2. Implement IFontProvider interface from iTextSharp and register the multi language font you will be using.
如果您按照这两个步骤操作，则可以创建多语言PDF 。
If you follow these 2 steps, you can create multi language 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;
}
}
static void Main (string[] args)
{
// step 1
Document document = new Document();
Byte[] bytes;
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))
{
document.Open();
