java水印组件和jspsmart组件的综合使用
要改写webedit的上传文件用百度搜ImageOperate
ImageOperate18.java
package com.image;
import java.awt.*;
import java.awt.image.*;
import javax.imageio.ImageIO.*;
import java.io.*;
import com.sun.image.codec.jpeg.JPEGCodec;
import com.sun.image.codec.jpeg.JPEGImageEncoder;

public class ImageOperate18 {
Image img1;
String message = "";
String filePath = ""; //程序本身所在的根目录，绝对路径。
String waterImg1 = "", waterImg2=""; //水印图片文件名
String waterPath = ""; //水印图片所在路径，绝对路径
String str = new String("www.baidu.cn");
public void waterImage(String oldFile, String newFile){
/* oldFile加水印前的文件名.
* newFile加水印后的文件名。
*/
try{
File myFile = new File(filePath + oldFile); //指定文件名含路径
Image src = javax.imageio.ImageIO.read(myFile); //构造Image对象
int w=src.getWidth(null); //得到源图宽
int h=src.getHeight(null); //得到源图长
Graphics gim = src.getGraphics();
BufferedImage tag = new BufferedImage(w,h,BufferedImage.TYPE_INT_RGB);
tag.getGraphics().drawImage(src,0,0,w,h,null);
if(!waterImg1.equals("") && waterImg2.equals("")){
Image img1 = javax.imageio.ImageIO.read(new File(waterPath+waterImg1));//构造Image对象
int w1 = img1.getWidth(null); //得到源图宽
int h1 = img1.getHeight(null); //得到源图长
tag.getGraphics().drawImage(img1,w-w1-12,h-30,w1,h1,null);
}
if(!waterImg1.equals("") && !waterImg2.equals("")){
Image img1 = javax.imageio.ImageIO.read(new File(waterPath+waterImg1));//构造Image对象
int w1 = img1.getWidth(null); //得到源图宽
int h1 = img1.getHeight(null); //得到源图长
Image img2 = javax.imageio.ImageIO.read(new File(waterPath+waterImg2));//构造Image对象
int w2 = img2.getWidth(null); //得到源图宽
int h2 = img2.getHeight(null); //得到源图长
tag.getGraphics().drawImage(img2,w-w2-12,h-30,w2,h2,null);
tag.getGraphics().drawImage(img1,w-w1-w2-15,h-32,w1,h1,null);
}
FileOutputStream out=new FileOutputStream(filePath + newFile); //输出到文件流
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
encoder.encode(tag); //JPEG编码
gim.dispose();
out.close();
}catch(Exception e){
message = waterPath + e.toString() + filePath;
}
}
public void writeImage(String oldFile, String newFile){

//设置字体
try{
File myFile = new File(filePath + oldFile); //指定文件名含路径
Image src = javax.imageio.ImageIO.read(myFile); //构造Image对象
int w=src.getWidth(null); //得到源图宽
int h=src.getHeight(null); //得到源图长
//在你创立的image上写字
Graphics gim = src.getGraphics();
Font font = new Font("Tahoma", Font.BOLD, 18);
gim.setFont(font);
gim.setColor(Color.black);
gim.drawString(str, w-(str.length()*10-3), h-5);
gim.setColor(Color.lightGray);
gim.drawString(str, w-(str.length()*10-2), h-6);
BufferedImage tag = new BufferedImage(w,h,BufferedImage.TYPE_INT_RGB);
tag.getGraphics().drawImage(src,0,0,w,h,null);
FileOutputStream out=new FileOutputStream(filePath + newFile); //输出到文件流
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
encoder.encode(tag); //JPEG编码
gim.dispose();
out.close();
}catch(Exception e){
message = e.toString();
}
}
public String getMessage(){
return this.message;
}
public void setFilePath(String filePath){
if(filePath!=null){
this.filePath = filePath;
}else{
this.filePath = "";
}
}
public void setStr(String str){
if(str!=null){
this.str = str;
}else{
this.str = "www.baidu.cn";
}
}
public void setWaterImg1(String str){
if(str!=null){
this.waterImg1 = str;
}else{
this.waterImg1 = "";
}
}
public void setWaterImg2(String str){
if(str!=null){
this.waterImg2 = str;
}else{
this.waterImg2 = "";
}
}
public void setWaterPath(String str){
if(str!=null){
this.waterPath = str;
}else{
this.waterPath = "";
}
}
}

使用时加入bean

<jsp:useBean id="mySmartUpload" scope="page" class="com.jspsmart.upload.SmartUpload" />
<jsp:useBean id="imageWrite18" scope="page" class="com.image.ImageOperate18"/>
