6.属性说明：
itextsharp-4.0.3-dll.zip 示例文件包含几乎所有的PDF处理需求
颜色：
Font fontChinese = new Font(bfChinese, 12, Font.NORMAL,new Color(0, 0, 0)); //黑Font fontChinese = new Font(bfChinese, 12, Font.NORMAL,new Color(0, 255, 0)); //绿

你可以添加一小段文本到你的文档中，但它并非文档内容的一部分，注释有标题和内容：
Annotation a = new Annotation( "authors", "Maybe it's because I wanted to be an author myself that I wrote iText.");
对齐方式：
cell.HorizontalAlignment = Element.ALIGN_CENTER;
cell.VerticalAlignment = Element.ALIGN_MIDDLE;
cell.VerticalAlignment = Element.ALIGN_MIDDLE;
下划线/删除线：
Chunk chunk1 = new Chunk("This text is underlined",FontFactory.getFont(FontFactory.HELVETICA, 12, Font.UNDERLINE));
Chunk chunk2 = new Chunk("This font is of type ITALIC | STRIKETHRU", FontFactory.getFont(FontFactory.HELVETICA, 12, Font.ITALIC | Font.STRIKETHRU));
Chunk chunk2 = new Chunk("This font is of type ITALIC | STRIKETHRU", FontFactory.getFont(FontFactory.HELVETICA, 12, Font.ITALIC | Font.STRIKETHRU));
加密：
public void setEncryption(boolean strength, String userPassword, String ownerPassword, int permissions);
