thanks for the when i run that it throws exception "Exception in thread "main" java.lang.OutOfMemoryError: Java heap space"

my code is as below:

BufferedImage buggImg = ImageIO.read(new File("Image1.jpg"));

AffineTransform tx = new AffineTransform();

tx.scale(200, 150);

AffineTransformOp op = new AffineTransformOp(tx, AffineTransformOp.TYPE_BILINEAR);

buggImg = op.filter(buggImg, null);

ImageIO.write(scale(buggImg, 200), "jpg", new File("image2.jpg"));

That's because your output image is too big.

> size of Image1.jpg is around 53x72... and the resulting scaled image is around (53 * 200) x (72 * 150) = 10600 x 10800I guess you meant a scale factor of 2.0 x 1.5
