- Name

GammaBrush -- correct gamma values of brush (V5.0)
- Synopsis
-
GammaBrush(id, red, green, blue)
- Library
-
brush
- Function
-
This function can be used to gamma correct the color channels of the
specified brush. For each color channel, you have to pass a floating
point value that specifies the desired gamma correction. A value of
1.0 means no change, a value smaller than 1.0 darkens the channel, a
value greater than 1.0 lightens the channel.
Note that if id specifies a palette brush, InvertBrush() will
just apply the gamma correction to the palette colors which makes this
function really fast when used with palette brushes.
Note that when using Miniwood, this function requires filters library.
