A bitmap picture can be represented by hexadecimal numbers. Each two-digit hexadecimal number represents a row. To convert a number into a picture, one converts the hexadecimal number into binary, then shades the bitmap according to the binary numbers. Each row represents one byte, that is, eight bits. A zero is a blank square, a one is a shaded square.

Consider the bitmap picture below:
