用java从和x格式的word文档中提取图片.doc

上海傲蓝科技用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。Doc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：package com.onlan.docx;import java.io.BufferedInputStream; import java.io.BufferedOutputStream; import java.io.File; import java.io.FileOutputStream; import java.util.Enumeration; import java.util.zip.ZipEntry; import java.util.zip.ZipFile; public class ImgExt4Docx /* * param args */ static final int BUFFER = 2048; public static void main(String args) String inputFilename = D:/work/test.docx; String unZipPathname = D:/work/unZipDir/; ImgExt4Docx ied=new ImgExt4Docx(); System.out.println(ied.unZipDocx(inputFilename,unZipPathname); /* * return the fold of the images */ public String unZipDocx(String docxfile,String destDir) try String inputFilename = docxfile; String unZipPathname = destDir; ZipFile zipFile = new ZipFile(inputFilename); Enumeration enu = zipFile.entries(); int i = 0; while(enu.hasMoreElements() ZipEntry zipEntry = (ZipEntry)enu.nextElement(); if(zipEntry.isDirectory() new File(unZipPathname+zipEntry.getName().mkdirs(); continue; BufferedInputStream bis = new BufferedInputStream(zipFile.getInputStream(zipEntry); File file = new File(unZipPathname+zipEntry.getName(); File parent = file.getParentFile(); if(parent != null & !parent.exists() parent.mkdirs(); FileOutputStream fos = new FileOutputStream(file); BufferedOutputStream bos = new BufferedOutputStream(fos,BUFFER); int count; byte array = new byteBUFFER; while(count = bis.read(array, 0, BUFFER)!=-1) bos.write(array, 0, BUFFER); bos.flush(); bos.close(); bis.close(); return destDir+word/media; catch(Exception e) e.printStackTrace(); return null; 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：package com.onlan;import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.InputStream;import java.io.OutputStream;import org.apache.poi.hwpf.HWPFDocument;import org.apache.poi.hwpf.model.PicturesTable;import org.apache.poi.hwpf.usermodel.CharacterRun;import org.apache.poi.hwpf.usermodel.Picture;import org.apache.poi.hwpf.usermodel.Range;public class ImgExt4Doc public void readWord(String docFile,String imgStoreDir) throws Exception File f = new File(docFile); / / File f = new File(D:worktest.doc); / InputStream in =new FileInputStream(f); HWPFDocument msWord=new HWPFDocument(in); String text=; PicturesTable pTable = msWord.getPicturesTable(); int numCharacterRuns = msWord.getRange().numCharacterRuns(); / ArrayList pList=msWord.getParagraphTable().getParagraphs(); / PAPX p=pList.get(0); int underlinecode = 0; int imgcount = 0; OutputStream out = null; int startOffset=0,endOffset; int enterCount=0; for (int i = 0; i numCharacterRuns; i+) CharacterRun characterRun = msWord.getRange().getCharacterRun(i); startOffset= characterRun.getStartOffset(); characterRun.getUnderlineCode(); endOffset= characterRun.getEndOffset(); / for(int m =startOffset;mendOffset;m+) / Range range = new Range(m,m+1,msWord); int hashCode=range.text().hashCode(); / System.out.println(range.text()+-+hashCode); CharacterRun cr=range.getCharacterRun(0); underlinecode = cr.getUnderlineCode(); if (underlinecode != 0 & range.text() != null) text = text +_; if(mendOffset&(hashCode = 13|hashCode=7)/get line enterCount+; / System.out.println(ENTER FIND.+enterCount); text=text + range.text(); / if (pTable.hasPicture(characterRun) /是图片则把图片位置替换为image标签，再把图片输出到指定位置 Picture pic = pTable.extractPicture(characterRun, true); String fileName = pic.suggestFullFileName(); byte content=pic.getContent(); out=new FileOutputStream(new File(imgStoreDir + File.separator + fileName);/save picture out.write(content); out.flush(); out.close(); text = text + ; imgcount+; in.close(); System.out.prin
