(crops by 5px all round)
>>ImageIO.write(cropped, "jpeg", new File("cropped.jpg");
should have been
ImageIO.write(cropped, "jpeg", new File("cropped.jpg"));
should have been
ImageIO.write(cropped, "jpeg", new File("cropped.jpg"));

well I am new to this so I am not sure how to get output in main method
public Image cropImage(Image img,int x, int y, int width, int height){
Image image = createImage(new FilteredImageSource(image. getSource( ), new CropImageFilter(x, y, width, height)));
return image;
}
what should be the main method for this??? how do I see the cropped jpg image??? and how do i pass in jpg image
public Image cropImage(Image img,int x, int y, int width, int height){
Image image = createImage(new FilteredImageSource(image.
return image;
}
what should be the main method for this??? how do I see the cropped jpg image??? and how do i pass in jpg image
Make the above method static then:
public static void main(String[] args) {
BufferedImage bi = ImageIO.read(new FileInputStream("x.jpg"));
// or use parameter
//BufferedImage bi = ImageIO.read(new FileInputStream(args[0]));
Image i = cropImage(bi, 5, 5, bi.getWidth() - 10, bi.getHeight() - 10);
}
public static void main(String[] args) {
BufferedImage bi = ImageIO.read(new FileInputStream("x.jpg"));
// or use parameter
//BufferedImage bi = ImageIO.read(new FileInputStream(args[0]));
Image i = cropImage(bi, 5, 5, bi.getWidth() - 10, bi.getHeight() - 10);
}
Display:
JFrame f = new JFrame();
f.getContentPane().add(new JLabel(new ImageIcon(i)));
f.pack();
f.setVisible(true);
JFrame f = new JFrame();
f.getContentPane().add(new
f.pack();
f.setVisible(true);
