I'm not convinced that you need the throws Exception on main. Then again, I haven't done Java in a while.

| Jan 17, 2017 at 0:44 | comment | added | Tatarize | Bunch of tricks to save 1 character, that coulda been more than saved by y[0] or any of the rest. import static javax.imageio.ImageIO.*;import java.io.*;class Main{public static void main(String[]y)throws Exception{java.awt.image.BufferedImage a=read(new File(y[0])),b=read(new File(y[1]));for(int i=0,q=a.getWidth();i<q*a.getHeight();)a.setRGB(i%q,i/q,a.getRGB(i%q,i/q)^b.getRGB(i%q,i++/q));write(a,"jpg",new File(y[2]));}} | |

| Jan 16, 2017 at 22:40 | comment | added | Tatarize | for (j=0;j++<a.getWidth();a.setRGB(j, i, a.getRGB(j, i) ^ read(new File(y[1])).getRGB(j, i))) write(a, "png", new File(y[2])); -- Feels wrong, but you can move the command of the second loop into the for's terminator section and then just save every single iteration of the loop, thereby getting rid of one semicolon. | |
| Jan 16, 2017 at 22:24 | comment | added | Tatarize | "Input can be taken as a path to the image" -- I gotta note y[0] (4 bytes) is fewer bytes than "a.png" (6 bytes) | |
| Jan 16, 2017 at 22:16 | comment | added | Tatarize | You can save a byte by doing ..."i++ < a.getHeight();)" | |

The file extension .png shouldn't be necessary

You can remove the public from public class M to save 7 bytes

You can save a byte by removing the space between String[] y. Just a minor little golf.

It looks much better with syntax highlighting
