InvertBrush(id)
id
, which means
that all colors are replaced with their complements (white
will become black, blue will become yellow etc.).
Note that if id
specifies a palette brush, InvertBrush()
will
just invert the palette colors which makes this function
really fast when used with palette brushes.
