1、北风网在线培训数字图像处理,第二讲：动态设置混合值 讲师：历风行,添加设置对话框,final JDialog dialog = new JDialog(frame,true); dialog.setBounds(200, 300, 300, 300); dialog.setLayout(null); JLabel blueLabel = new JLabel(蓝色); final JTextField blueField = new JTextField(); blueLabel.setBounds(50, 10, 30, 20); blueField.setBounds(100,10,100

2、,20); dialog.add(blueLabel); dialog.add(blueField); JLabel greenLable = new JLabel(绿色); final JTextField greenField= new JTextField(); greenLable.setBounds(50, 40, 30, 20); greenField.setBounds(100,40,100,20); dialog.add(greenLable); dialog.add(greenField);,添加设置对话框,JLabel redLable = new JLabel(红色);

3、final JTextField redField = new JTextField(); redLable.setBounds(50, 70, 30, 20); redField.setBounds(100,70,100,20); dialog.add(redLable); dialog.add(redField); JButton button = new JButton(确定); button.setBounds(100, 100, 100, 30);,为按钮添加监听器,button.addMouseListener(new MouseAdapter() public void mous

4、eClicked(MouseEvent e) int blue = 0; int red = 0; int green = 0; blue = Integer.parseInt(blueField.getText(); green = Integer.parseInt(greenField.getText(); red = Integer.parseInt(redField.getText(); filter.setIntoB(30); filter.setIntoG(30); filter.setIntoR(30); BufferedImage src = new BufferedImage(image.getWidth(null),image.getHeight(null),BufferedImage.TYPE_INT_RGB); src.getGraphics().drawImage(image, 0, 0, null); BufferedImage dst = src; image = filter.filter(src, dst); beforeImage = image; dialog.setVisible(false);
