学习：ITEXT导出doc
首先我们需要的是itext.jar包。
itext是一个开源的rtf、pdf读写项目，属于sourceforge。rtf即是Rich Text Format，由微软公司开发的跨平台文档格式，缺点在于保存的大小会比较大，可能是由于考虑了兼容性的关系。
它的读写方式是比较通用的，无论是写rtf、pdf还是html，都有统一的Document，不同的格式有不同的写入器。如RTFWriter\PDFWriter。
下面记录几个概念：
1、 Font，字体对象
2、 Chunk，文本块，处理文本的最小单位，可以设置字体，颜色，等。
3、 Phrase，短语，由一个或多个Chunk组成。
4、 Paragraph，段落，由一个或多个Chunk以及Phrace组成。
5、 Chapter，章节对象
6、 Section，小节对象
7、 Table，表格对象
8、 Image，图像对象
