The idea is that the 8-bit input range 0..255 should map to the 16-bit
output range 0..65535 ... Try the original code, compared to your
suggestion;)
(To be honest, multiplying by 257 did sound weird to me, too, but then
I realized that 257 == 65535/255 . I would perhaps write out the
65535/255 explicitly and let the compiler fold it to 257.)
