- Name

ModulateBrush -- change brightness, saturation, and hue of brush (V5.0)
- Synopsis
-
ModulateBrush(id, brightness, saturation, hue)
- Function
-
This function can be used to change the brightness, saturation, and hue
settings of a brush. For each setting, you need to pass a floating point
value that describes the desired change. A value of 1.0 means no change,
a value smaller than 1.0 reduces the brightness/saturation/hue, while a
value greater than 1.0 enhances it.
Note that if id specifies a palette brush, ModulateBrush() will
just modulate the palette colors which makes this function
really fast when used with palette brushes.
- Inputs
-
- id
- brush to modulate
- brightness
- desired brightness correction
- saturation
- desired saturation correction
- hue
- desired hue correction
- Example
-
ModulateBrush(1, 1.0, 2.0, 1.0)
The code above increases the saturation while leaving brightness and
hue untouched. The result is an image with emphasized colors, just like
in a cartoon.
