我已經嘗試了看寫/保存圖像的Oracle建議，但沒有任何工作。我有一個開始按鈕，開始將2張圖像從一個圖像混合到另一個圖像。然後一個停止按鈕來中途停止混合（或任何你想要的），然後我有一個saveImage按鈕，並希望它捕獲圖像的當前狀態並將其保存到文件。但是如何？這裏是從Frame.java我無法將我的圖像（中間混合）保存到文件？
import java.awt.AlphaComposite;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Image;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.image.BufferedImage;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JPanel;
import javax.swing.Timer;
class Frame extends JPanel implements ActionListener {
private static final long serialVersionUID = 1L;
private Image MeSmaller1;
private Image MeSmaller2;
protected Timer timer;
private float alpha;
JPanel pnlButton = new JPanel();
static JButton btnStartBlend = new JButton("Start Blend");
static JButton btnStopBlend = new JButton("Stop Blend");
static JButton saveImage = new JButton("Save Image To File");
public Frame() {
loadImages();
initTimer();
pnlButton.add(btnStartBlend);
this.add(pnlButton);
pnlButton.add(btnStopBlend);
this.add(pnlButton);
pnlButton.add(saveImage);
this.add(pnlButton);
addListeners();
}
// start button actionlistener
public void addListeners() {
btnStartBlend.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
initTimer();
timer.start();
System.out.println("Timer started");
}
});
// stop button actionlistener
btnStopBlend.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
// initTimer();
timer.stop();
System.out.println("Timer stopped");
}
});
// Save button actionlistener
saveImage.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
System.out.println("Save image clicked");
}
});
}
private void loadImages() {
MeSmaller1 = new ImageIcon("MeSmaller1.jpg").getImage();
MeSmaller2 = new ImageIcon("MeSmaller2.jpg").getImage();
}
public void initTimer() {
timer = new Timer(1000, this);
timer.start();
timer.stop();
alpha = 1f;
}
private void doDrawing(Graphics g) {
Graphics2D g2Dim = (Graphics2D) g;
// below sets the size of picture
BufferedImage buffImage = new BufferedImage(400, 600,
BufferedImage.TYPE_INT_ARGB);
Graphics2D gBuffI = buffImage.createGraphics();
AlphaComposite aComp = AlphaComposite.getInstance(
AlphaComposite.SRC_OVER, alpha);
// decides where images are drawn in JFrame
gBuffI.drawImage(MeSmaller1, 28, 55, null);
gBuffI.setComposite(aComp);
gBuffI.drawImage(MeSmaller2, 30, 48, null);
g2Dim.drawImage(buffImage, 10, 10, null);
}
public static void saveToFile(BufferedImage img) {
}
@Override
public void paintComponent(Graphics g) {
super.paintComponent(g);
doDrawing(g);
}
@Override
public void actionPerformed(ActionEvent e) {
alpha -= 0.1;
if (alpha <= 0) {
alpha = 0;
timer.stop();
System.out.println("Morph Finished please restart.");
}
repaint();
}
}
代碼誰能幫助這裏它只是不工作。還有另一個類PictureMorph.java
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
public class PictureMorph extends JFrame {
private static final long serialVersionUID = 1L;
public PictureMorph() {
initUI();
}
private void initUI() {
JFrame frame = new JFrame ("Image Morph");
setTitle("Facial Image Manipulation");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
add(new Frame());
// below set Frame Size around image
setSize(380, 470);
setLocationRelativeTo(null);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
PictureMorph picMorph = new PictureMorph();
picMorph.setVisible(true);
}
});
}
}
3班（我認爲可能是多餘的現在居然？）叫BtnStartBlendListener，BtnStopBlendListener，SaveImageListener不包含多少代碼在所有。誰能幫忙？
評論是不是擴展討論;這個對話已經[轉移到聊天]（http://chat.stackoverflow.com/rooms/75538/discussion-on-answer-by-alainlompo-i-cant-save-my-image-mid-blend-to-文件）。 – Taryn
@bluefeet對不起，感謝你提醒我們這個規則。最好的祝願。 – alainlompo
