把文本文件的文字读出来,然后写到PDF文件

其中两个文件关于编码和字体（下面例子会用到）。

cjkencodings.properties

UniGB-UCS2-H=UniGB-UCS2-H

UniGB-UCS2-V=UniGB-UCS2-HUniGB-UCS2-V

cjkfonts.properties

STSong-Light=Adobe-GB1-UCS2_UniGB-UCS2-H_UniGB-UCS2-V_

STSongStd-Light=Adobe-GB1-UCS2_UniGB-UCS2-H_UniGB-UCS2-V_

 

我下载的是目前最新的包——itext-1.4.7.jar　一个简单的示例代码如下：

package powerwind;

 

import java.io.*;

 

import com.lowagie.text.*;

import com.lowagie.text.pdf.*;

 

// 功能:把文本文件的文字读出来,然后写到PDF文件

publicclass TxtToPdf {

 

    publicstaticvoid main(String[] args) {

 

       Document doc = null;

       BufferedReader br = null;

 

       final String pdfFilename = "PdfFile.pdf";

       final String txtFilename = "TxtFile.txt";

       // 设置纸张为A5

 

       try {

           doc = new Document();

       　　doc.setPageSize(PageSize.A5);

 

           PdfWriter.getInstance(doc, new FileOutputStream(pdfFilename));

 

           // 设置字体和编码：

           BaseFont baseFont = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);

           Font font = new Font(baseFont, 8, Font.NORMAL);

           doc.open();

 

           br = new BufferedReader(new FileReader(txtFilename));

           String str = null;

           // 从txt文件读出一行,加入到Document的段落

           while ((str = br.readLine()) != null) {

              doc.add(new Paragraph(str, font));

           }

       } catch (DocumentException de) {

           System.out.println(de);

       } catch (IOException ioe) {

           System.out.println(ioe);

 

       } finally {

           if (doc != null)

              doc.close();

           try {

              if (br != null)

                  br.close();

           } catch (IOException ioe) {

              System.out.println(ioe);

           }

       }

       System.out.println("done");

    }

}
