They are represented as sequences of bytes, which themselves are composed of bits, all of which is binary... I'm not sure what exactly you're asking there.

Graphics file formats aren't just "lines"--they have structure which is more complex than I think you think it is. I recommend you do a little research on your own first; these should get you started:

A picture or an image is made from a sequence of pixels.
