Divide the bitmap in horizontal strips of 4 pixels (let's call them nibbles).
Use the following table to map each nibble to a hexadecimal number where 0 =white, 1=black:
0000 = 0
0001 = 1
0010 = 2
0011 = 3
0100 = 4
0101 = 5
0110 = 6
0111 = 7
1000 = 8
1001 = 9
1010 = A
1011 = B
1100 = C
1101 = D
1110 = E
1111 = F
