- brightness (int)
The brightness value used, -150 to 150.
- contrast (float)
The contrast value, -1 to infinity, where a negative value decreases contrast, zero does nothing and positive values increase contrast.
If true, brightness will be adjusted the same way Photoshop used to prior to CS3 (now called "Legacy" in the B&C dialog). This means the brightness value is simply added to the pixel value, in effect shifting the entire histogram left or right.
If true, this means the brightness values are inverted to swap black and white.
