#define    BM_AWS_GET_R(color)                (color & 0x0000FF);

                  qColor *to = (qColor*)qcolor;
    quint    r, g, b;   
    // black is special
    if ( color == 0 )
        color = color + 1;

    r = BM_AWS_GET_R(color);
    g = BM_AWS_GET_G(color);
    b = BM_AWS_GET_B(color);
    to->red  = (quint16)(r) * 0xffff / 0xff;
    to->green = (quint16)(g) * 0xffff / 0xff;
    to->blue  = (quint16)(b) * 0xffff / 0xff;
    to->pixel = G_RGB(r, g, b);
