如何实现图象的拷贝、剪切和粘贴？

[猛将]

我想实现对application界面上的图象进行拷贝、剪切和粘贴等操作，能实现吗？
给点源代码吧

[Asprilla]

源码就没有，你可以看java2核心技术2册里有介绍.

up!

too simple ,use methed :darwImage(Image img,int ,int y,ImageObserver obsever),use you head and see the method in java doc.

import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;

public class TranslateTest extends Applet {
Image image;
Point pressed = new Point(), lastTranslate = new Point();

public void init() {
image = getImage(getCodeBase(), "saint.gif");
try {
MediaTracker mt = new MediaTracker(this);
mt.addImage(image, 0);
mt.waitForID(0);
}
catch(InterruptedException e) {
e.printStackTrace();
}
addMouseListener(new MouseAdapter() {
public void mousePressed(MouseEvent e) {
Point loc = e.getPoint();

// adjust mouse pressed location for
// translation ...
pressed.x = loc.x - lastTranslate.x;
pressed.y = loc.y - lastTranslate.y;
}
});
addMouseMotionListener(new MouseMotionAdapter() {
public void mouseDragged(MouseEvent e) {
Point loc = e.getPoint();
Point translate = new Point(loc.x - pressed.x,
loc.y - pressed.y);
Graphics g = getGraphics();

try {
g.clearRect(0,0,
getSize().width,getSize().height);
g.translate(translate.x, translate.y);
showStatus("Translating Graphics: " +
translate);

g.drawImage(image, 0, 0, TranslateTest.this);
}
finally {
g.dispose();
}
lastTranslate = translate;
}
});
}
public void paint(Graphics g) {
g.drawImage(image, 0, 0, this);
}
}

用剪贴板实现就可以了

to oscarzhou88:
你的程序是实现图象的拖动，如何实现选取图象一部分进行的拷贝、剪切和粘贴之类的功能呢？
