Depends on the format of that UINT32… Something like:

    SDL_Color c;
    c.r = i >> 16;
    c.g = i >> 8;
    c.b = i;

and
i = (c.r << 16) | (c.g << 8) | c.b;

I think that should work, the uin32 is something like 0xff00ff. I knew
it could be solved with shifts, but I didnt knew the correct syntax in C
and if it also requires some specific order.
Thanks a lot.
