今天我无意中看到的.
程序代码如下:
- import java.awt.image.BufferedImage;
- import java.io.File;
- import java.io.IOException;
- public class TestImageIO {
- public static void main(String[] args) throws IOException {
- if (args.length < 1)
- {
- System.out.println("error in parameter!");
- return;
- }
- File imageFile = new File(args[0]);
- BufferedImage image = ImageIO.read(imageFile);
- for (int i=0; i<image.getHeight(); i++) {
- for (int j=0; j<image.getWidth(); j++) {
- System.out.print(" " + image.getRGB(j,i) + " ");
- }
- System.out.println();
- }
- File outFile = new File("out.jpg");
- ImageIO.write(image, "jpg", outFile);
- }
- }
-bash-3.00$ javac TestImageIO.java
-bash-3.00$ java TestImageIO d0bo806aapvqs.jpg
