如何替换word文档中已经插入的图片？我想把图片替换掉，尺寸不改变，并且加上边框

Posted 2023-04-16

我已经帮你在10WORD中试验过了，如果直接点击图片右键插入另外不同尺寸的图片，是不能保持图片原有的尺寸，你可以把需要替换的图片插入进来，根据原来的图片尺寸进行裁剪，再替换，就可以了。或者用PS把尺寸处理为大小一样的，可直接替换。

加边框：在“页面布局”选择“页面边框”，再选择“边框”选项，可设置边框颜色、宽度。或者右键单击图片，选择“设置图片格式”，也可设置“线条颜色”、“线型”等样式。追问

谢谢

参考技术A 右键图片格式能查看图片尺寸，然后把图片剪贴掉，再插入新图片，重新设置尺寸。追答

格式设置中可添加边框

参考技术B 选中图片，右键，更改图片，07版本追问

我的是03版本，没有更改图片这项

使用poi根据模版生成word文档，支持插入数据和图片

一、制作word模版，${xxxx}是一会要替换的内容，最下面的表格是要插入数据，根据是否以$开头来判断是需要替换还是插入数据，

　　注意如果是需要插入数据，制作的表格模版需要一行空行，也只能有一行空行，原因可以看我代码的逻辑，表格中${header}

　　和${hearder2}是放入需要替换的图片

 

二、添加poi所需要的jar包文件，我用的maven对jar包进行管理

 

<dependency>
      <groupId>org.apache.poi</groupId>
      <artifactId>poi</artifactId>
      <version>3.11</version>
</dependency>
<dependency>
      <groupId>org.apache.poi</groupId>
      <artifactId>poi-ooxml</artifactId>
      <version>3.11</version>
</dependency>

 

 

三、由于poi自身bug,会出现图片无法显示问题，这里需要自定义一个类继承XWPFDocument类，接下来使用的都是我们自己创建的这个类来操作word对象，这个

　　类对XWPFDocument进行了继承，所以不用担心会有什么问题

package com.cccuu.project.myUtils;

import org.apache.poi.openxml4j.opc.OPCPackage;
import org.apache.poi.xwpf.usermodel.XWPFDocument;

            testList.add(new String[]{"2","2AA","2BB","2CC"});
            testList.add(new String[]{"3","3AA","3BB","3CC"});
            testList.add(new String[]{"4","4AA","4BB","4CC"});
            String path="C:/Users/Administrator/Desktop/jar包/mobanFile.docx";  //模板文件位置
            String fileName= new String("测试文档.docx".getBytes("UTF-8"),"iso-8859-1");    //生成word文件的文件名
            wordUtil.getWord(path,params,testList,fileName,response);

        }catch(Exception e){
            e.printStackTrace();
        }
    }

 

六、最后生成的word文档
