我是结合在jspsmart.upload下使用的,这个是imgbean的代码 package com.pic;
import java.awt.*; import java.awt.event.*; import java.io.*; import java.awt.image.*; import org.w3c.dom.*; import com.sun.image.codec.jpeg.*; import javax.imageio.*;
public class ImgBean_i{ public void ImgBean_i(){
}
public void ImgYin(String Imagename_biao,String ImgName){ try{ File _file = new File(ImgName); Image src = ImageIO.read(_file); int wideth=src.getWidth(null); int height=src.getHeight(null); BufferedImage image=new BufferedImage(wideth,height,BufferedImage.TYPE_INT_RGB); Graphics g=image.createGraphics(); g.drawImage(src,0,0,wideth,height,null);
//水印文件 File _filebiao = new File(Imagename_biao); Image src_biao = ImageIO.read(_filebiao); int wideth_biao=src_biao.getWidth(null); int height_biao=src_biao.getHeight(null); g.drawImage(src_biao,wideth-110,height-110,wideth_biao,height_biao,null); //水印文件在原图片文件的位置,原图片文件的右下角为wideth-0,height-0 g.dispose(); FileOutputStream out=new FileOutputStream(ImgName); JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out); encoder.encode(image); out.close(); } catch(Exception e){ System.out.println(e); } } } 以下是修改过的smartupload代码 <%@ page language="java" import="com.jspsmart.upload.*" import="java.util.*,java.text.*"%> <%@ page contentType="text/html;charset=GBK" %>
