iText操作pdf（生成，导入图片等）

生成pdf有很多种方法，用pdfbox也很方便，今天我要写的是用iText

主要在pom.xml中配置的jar包如下

<dependency>
            <groupId>com.lowagie</groupId>
            <artifactId>itext</artifactId>
            <version>4.2.2</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.eclipse.birt.runtime.3_7_1/com.lowagie.text -->
        <!--<dependency>
            <groupId>org.eclipse.birt.runtime.3_7_1</groupId>
            <artifactId>com.lowagie.text</artifactId>
            <version>2.1.7</version>
        </dependency>
-->
        <!-- https://mvnrepository.com/artifact/com.itextpdf/itextpdf -->
        <dependency>
            <groupId>com.itextpdf</groupId>
            <artifactId>itextpdf</artifactId>
            <version>5.5.11</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/com.itextpdf/itext-asian -->
        <dependency>
            <groupId>com.itextpdf</groupId>
            <artifactId>itext-asian</artifactId>
            <version>5.2.0</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/com.lowagie/itext-rtf -->
        <dependency>
            <groupId>com.lowagie</groupId>
            <artifactId>itext-rtf</artifactId>
            <version>2.1.7</version>
        </dependency>

如下代码所示，是生成pdf并且插入文字与图片

//创建pdf文件，并且写入文字跟图片
  public void createPdfWithImg) {
    Document document = null;
    try {
      BaseFont bfChinese = BaseFont.createFont"STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);// 设置中文字体
      Font headFont = new FontbfChinese, 10, Font.NORMAL);// 设置字体大小

      document = new Document);
      PdfWriter.getInstancedocument, new FileOutputStream"D:/img.pdf"));
      //设定文档的作者
      document.addAuthor"张小宁"); //测试无效
      document.open);
      document.addnew Paragraph"你好，Img！", headFont));
      //读取一个图片
      Image image = Image.getInstance"C:\Users\zhxn\Desktop\1.jpg");
      //插入一个图片
      document.addimage);
    } catch FileNotFoundException e) {
      e.printStackTrace);
    } catch DocumentException e) {
      e.printStackTrace);
    } catch MalformedURLException e) {
      e.printStackTrace);
    } catch IOException e) {
      e.printStackTrace);
    } finally {
      if document != null) {
        document.close);
      }
    }
  }

其余都不想写了，项目中也大概就需要这些
