Shrinking an image by skipping pixels

 


import java.awt.image.BufferedImage;

public class Main {
  static BufferedImage enlarge(BufferedImage image, int n) {
    int w = image.getWidth() / n;
    int h = image.getHeight() / n;

    BufferedImage shrunkImage = new BufferedImage(w, h, image.getType());

    for (int y = 0; y < h; ++y)
      for (int x = 0; x < w; ++x)
        shrunkImage.setRGB(x, y, image.getRGB(x * n, y * n));

    return shrunkImage;
  }
}
