This routine is faster than the one included with Gtk 1.0 for a number
|
|
of reasons:
|
|
|
|
1. Shifting instead of lookup tables (less memory traffic).
|
|
|
|
2. Much less register pressure, especially because shifts are
|
|
in the code.
|
|
|
|
3. A memcpy is avoided (i.e. the transfer function).
|
|
|
|
4. On big-endian architectures, byte swapping is avoided.
|
|
|
|
That said, it wouldn't be hard to make it even faster - just make an
|
|
inner loop that reads 3 words (i.e. 4 24-bit pixels), does a lot of
|
|
shifting and masking, then writes 2 words.
