[classlib][awt]BufferedImage.getSubimage method is incorrect
[classlib][awt]BufferedImage.getSubimage method is incorrect
------------------------------------------------------------
Key: HARMONY-4221
URL: https://issues.apache.org/jira/browse/HARMONY-4221
Project: Harmony
Issue Type: Bug
Components: Classlib
Reporter: Dmitry Irlyanov
Priority: Minor
according spec, BufferedImage.getSubimage(int x, int y, int w, int h) method takes 2 first ints as a upper-left corner coordinate of subimage. But harmony implementation takes upper-left corner point as (0,0)
Look at the following code:
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.JFrame;
import junit.framework.TestCase;
public class cropTest extends TestCase {
public void testCrop() throws IOException {
final BufferedImage image = ImageIO.read(new File(cropTest.class
.getResource("test.png").getPath()));
JFrame f = new JFrame() {
@Override
public void paint(Graphics g) {
g.drawImage(image.getSubimage(0, 0, 10, 10), 100, 100, 100,
100, null);
g.drawImage(image.getSubimage(0, 10, 10, 10), 100, 200, 100,
100, null);
g.drawImage(image.getSubimage(0, 20, 10, 10), 100, 300, 100,
100, null);
g.drawImage(image.getSubimage(10, 0, 10, 10), 200, 100, 100,
100, null);
g.drawImage(image.getSubimage(10, 10, 10, 10), 200, 200, 100,
100, null);
g.drawImage(image.getSubimage(10, 20, 10, 10), 200, 300, 100,
100, null);
g.drawImage(image.getSubimage(20, 0, 10, 10), 300, 100, 100,
100, null);
g.drawImage(image.getSubimage(20, 10, 10, 10), 300, 200, 100,
100, null);
g.drawImage(image.getSubimage(20, 20, 10, 10), 300, 300, 100,
100, null);
}
};
f.setSize(500, 500);
f.setVisible(true);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
