截屏工具 java.doc

截屏工具一、工具软件简介：MyEclipse，是在eclipse 基础上加上自己的插件开发而成的功能强大的企业级集成开发环境，主要用于Java、Java EE以及移动应用的开发。MyEclipse的功能非常强大，支持也十分广泛，尤其是对各种开源产品的支持相当不错。二、设计要求：1) 能够全屏截屏；2) 能够手动选择局部矩形截屏；3) 能够定时截屏；4) 能够将截屏的图片存储在指定文件夹；5) 除以上功能外，还可根据实际需要添加其他功能。三、类和方法的设计：类：主窗口类，截图类，截全屏类四、核心方法窗口功能菜单设计：import java.awt.BorderLayout;import java.awt.EventQueue;import javax.swing.JFrame;import javax.swing.JPanel;import javax.swing.border.EmptyBorder;import javax.swing.JTextField;import javax.swing.JCheckBox;import javax.swing.JButton;import java.awt.event.ActionListener;import java.awt.event.ActionEvent;import java.util.Calendar;import java.util.Timer;import java.util.TimerTask;import javax.swing.SwingConstants;import java.awt.Window.Type;import java.awt.Dialog.ModalExclusionType;public class Chuangkou extends JFrame private JPanel contentPane;protected String args;/* * Launch the application. */public static void main(String args) EventQueue.invokeLater(new Runnable() public void run() try Chuangkou frame = new Chuangkou();frame.setVisible(true); catch (Exception e) e.printStackTrace(););/* * Create the frame. */public Chuangkou() setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);setBounds(100, 100, 450, 300);contentPane = new JPanel();contentPane.setBorder(new EmptyBorder(5, 5, 5, 5);setContentPane(contentPane);contentPane.setLayout(null);JButton btnNewButton = new JButton(截图);btnNewButton.setBounds(237, 10, 192, 247);btnNewButton.addActionListener(new ActionListener() public void actionPerformed(ActionEvent arg0) AWTpicture a=new AWTpicture();a.setBackground(getBackground(););contentPane.add(btnNewButton);JButton button = new JButton(全屏);button.setBounds(5, 10, 192, 247);button.addActionListener(new ActionListener() public void actionPerformed(ActionEvent e) GuiCamera a= new GuiCamera();a.main(null););button.setToolTipText();contentPane.add(button);截全屏类import java.awt.Dimension; import java.awt.Rectangle; import java.awt.Robot; import java.awt.Toolkit; import java.awt.image.BufferedImage; import java.io.File; import javax.imageio.ImageIO; public class GuiCamera private String fileName; /文件的前缀 private String defaultName = GuiCamera; static int serialNum=0; private String imageFormat; /图像文件的格式 private String defaultImageFormat=png; Dimension d = Toolkit.getDefaultToolkit().getScreenSize(); /* * 默认的文件前缀为GuiCamera，文件格式为PNG格式 * The default construct will use the default * Image file surname GuiCamera, * and default image format png */ public GuiCamera() fileName = defaultName; imageFormat=defaultImageFormat; /* * param s the surname of the snapshot file * param format the format of the image file, * it can be jpg or png * 本构造支持JPG和PNG文件的存储 */ public GuiCamera(String s,String format) fileName = s; imageFormat=format; /* * 对屏幕进行拍照 * snapShot the Gui once */ public void snapShot() try /拷贝屏幕到一个BufferedImage对象screenshot BufferedImage screenshot = (new Robot().createScreenCapture(new Rectangle(0, 0, (int) d.getWidth(), (int) d.getHeight(); serialNum+; /根据文件前缀变量和文件格式变量，自动生成文件名 String name=fileName+String.valueOf(serialNum)+.+imageFormat; File f = new File(name); System.out.print(Save File +name); /将screenshot对象写入图像文件 ImageIO.write(screenshot, imageFormat, f); System.out.print(.Finished!n); catch (Exception ex) System.out.println(ex); public static void main(String args) GuiCamera cam= new GuiCamera(d:图片, png);/ cam.snapShot(); 五、总结： 经过java记事本的课程设计，我在老师的指导下，和同学的帮助下，顺利完成该课程设计。通过这次课程设计，我收获到了很多，这次JAVA课程设计给我的最大的印象就是
