I use less accurate approximation here by simply left-shifting the input

| 232 |
value and filling the low order bits with zeroes. This method improves PNG
|
| 233 |
compression but this scheme cannot reproduce white exactly, since it does
|
| 234 |
not generate an all-ones maximum value; the net effect is to darken the
|
| 235 |
image slightly.
|
| 236 |
|
| 237 |
The better method should be "left bit replication":
