>could it be that the "WinRGBToIndex" call is very slow ?

Well, "very" is obviously subjective, so it is hard to give an absolute
answer.  However, think about what the routine needs to do: given a
three-byte value, search through 256 unsorted and presumably unique values
to find the closest one to the given value.

No wonder it is slow :-)

Presumably you'd be able to cache the index that you want, unless you're
changing the palette all the time.
