java图片编辑器

Ⅳ 如何用java方法获取编辑器中第一张图片

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class IconsDemo extends JFrame{
private static Icon[] icons;
private JButton jb1,jb2=new JButton("Disable");
private boolean flag=false;
public IconsDemo(String title){
super(title);

icons=new Icon[]{
new ImageIcon(getClass().getResource("0.jpg")),//图片提取
new ImageIcon(getClass().getResource("1.jpg")),
new ImageIcon(getClass().getResource("2.jpg")),
new ImageIcon(getClass().getResource("3.jpg")),
new ImageIcon(getClass().getResource("4.jpg")),
};
jb1=new JButton("pet",icons[0]);
Container contentPane=getContentPane();
contentPane.setLayout(new FlowLayout());
jb1.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
if(flag){
jb1.setIcon(icons[0]);
flag=false;
}
else{

jb1.setIcon(icons[1]);
flag=true;

}
jb1.setVerticalAlignment(JButton.TOP);
jb1.setHorizontalAlignment(JButton.LEFT);

}
});
jb1.setRolloverEnabled(true);//为true则绘制翻转效果为false无效果
jb1.setRolloverIcon(icons[2]);//鼠标移动到按钮区域的图标
jb1.setPressedIcon(icons[3]);//鼠标按下按钮后的图标
jb1.setDisabledIcon(icons[4]);//按钮无效状态下的图标
jb1.setToolTipText("click me");
contentPane.add(jb1);
jb2.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
if(jb1.isEnabled()){
jb1.setEnabled(false);
jb2.setText("Enable");
}
else{
jb1.setEnabled(true);
jb2.setText("Disable");
}

}
});

contentPane.add(jb2);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//关闭程序
pack();
setVisible(true);

}
public static void main(String[] args){

new IconsDemo("hellow");

}

}

Ⅵ java，或者javaweb中如何实现图片编辑器的功能，，什么方法，什么代码，就可以得到和电脑自带的那个画板

你好，Java Image Editor
http://www.jhlabs.com/ie/
ImageEditor。可以用现成的东西！！！

Ⅶ 有没有什么好用的JAVA图形界面编辑器

NETBEANS的GUI设计已经算是最为优秀的了，再觉得不好用的话，那你还是自己拼代码设计吧。

Ⅷ 我java系统里面要加一个图片编辑的功能 应该用什么技术做

Java 完全可以出色的实现多媒体的编辑与处理，包括图象的处理技术（ JGraph ）、动画技术（ JFlash ）、声音视频技术（ JMF ）等等；

Java 对图象处理进行了很好的支持，通过 java 提供的类，我们完全可以对图象进行各种常见的操作和变换；
1、 java图形图象处理所用到的相关类与接口：
java.awt.color、java.awt.grahpics、java.awt.image、
java.awt.image.bufferedimage、java.awt.image.LookupOp、
java.awt.image.ConvolveOp、java.awt.image.AffineTransformOp、
bufferedimageop接口及其实现类等；

2、 java 图形图象处理可以完成的功能：

图象文件的打开（浏览）与保存（支持 jpg 、 jpeg 、 gif 、 png 等）、放大镜操作、旋转与镜像操作、反色和其他反色、黑白色阈值处理、亮度调整、缩放显示、边缘化、图形的锐化和钝化、其它功能等； .

Ⅸ 适合java系统类似于美图秀秀的图片编辑软件

早期java软件比较少这类软件，毕竟早期都是开发小游戏
现在都基于android或者iphone平台开发了，所以建议最好还是在电脑上做编辑

Ⅹ 用JAVA实现的图形编辑器

楼主给你一个我的，直接保存成pb.java编译运行，就是你要的画图功能 ，可以参考一下
