1、用JaVa从DOC和DOCX格式的Word文档中提取图片DOC和DOCX的文档格式因为存储格式不一样，所以需要用不通的方法提取图片。DOCX格式的文档实际上是压缩文件，用程序提取图片相对实际上只需要对文章进行解压缩,然后到指定文件夹找到图片即可。DOe文档则需要把图片数据读出来，再生成文件。下面代码均可直接运行。从DoCX文件中提取图片的代码：packagecom.on1an.docx;importjavaio,BufferedInputStream;importjava.io.BufferedOutputStream;importjava.io.Fi1e;importjava.io.Fi1e

6、tDir+wordmedia;catch(Exceptione)eprintStackTrace();returnnu11;)从Doc文件中提取图片的代码，该代码不仅可以从文档中提取图片，还可以把DOC文档中图片所在位置加上标签以及图片文件名，与提取的图片对应起来：packagecom.on1an;importjava.io.Fi1e;importjava.io.Fi1eInputStream;importjava.io.Fi1eOutputStream;importjava.io.Inputstream;importjava.io.OutputStream;importorg.apache.
