Change background color : dump_image

There is a dump_image command in
LAMMPS, which generates images of simulation box at desired timesteps. I
have generated the images but the background is black as shown in attached
file. Can anyone please tell me the option so that background can be changed
to white. Or if it can be changed by some other means. Need urgent help
