this one is pretty buggy. space to start scanning USE TURBO MODE!!! or else it will be VERY SLOW!!!!! you can do this by holding shift and clicking the flag!!! if you decide to put in an image, it MUST fill the entire screen, i.e, if you put in image of an apple, no matter how small it is, it must have some kind of background that fills the entire screen, or else colors could bug a little bit.
