Lets you control the brightness, saturation, and hue of an image. Hue
is the percentage of absolute rotation from the current position. For
example 50 results in a counter-clockwise rotation of 90 degrees, 150
results in a clockwise rotation of 90 degrees, with 0 and 200 both
resulting in a rotation of 180 degrees.
Parameters
brightness
