Turning an Image File into a binary Bitmask in Java

Some people who have stumbled across my LED Hoop have asked how I imported the Carrot logo into a bitmask in source code.

I thought I had deleted it, but I recently found it...

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;

public class ImageRead {

    public static boolean hilo(int pixel) {
    	int r, g, b;
    	r = (pixel >> 16) & 0xFF;
    	g = (pixel >> 6) & 0xFF;
    	b = (pixel) & 0xFF;
    	return (r + g + b > 0x7F * 3);
    }

    public static void main(String[] args) throws IOException {
    	BufferedImage img = ImageIO.read(new File("carrotboolean.jpg"));
    	int width = img.getWidth();
    	int heighth = img.getHeight();
    	System.out.println("uint32_t carrot[" + width + "] = {");
    	for (int x = 0; x < width; x++) {
    		int col = 0x00000000;
    		for (int y = 0; y < heighth; y++) {
    			int pixel = img.getRGB(x, y);
    			if (hilo(pixel)) {
    				col++;
    			}
    			col <<= 1;
    		}
    		System.out.print("0x");
    		for(int j=Integer.toHexString(col).length()-8; j<0;j++)
    			System.out.print("0");
    		System.out.println(Integer.toHexString(col).toUpperCase()+",");
    	}
    }

}

I hope this saves someone some time. It worked at least once, and that's all I needed it for. I make no guarantees that it will work a second time, but it might save someone some time.
