Parameters

  • 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.
  • legacy (bool)
    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.
  • invert(bool)
    If true, this means the brightness values are inverted to swap black and white.
