  • Enabling of zebras of overexposure image zones. ‘true’ to enable the zebras of overexposure zone.

    Declaration

    Swift

    public var zebrasEnabled: Bool { get set }

  • Threshold of overexposure used by zebras, in range [0.0, 1.0]. ‘0.0’ for the maximum of zebras and ‘1.0’ for the minimum.

    Default value is 0,94.

    Declaration

    Swift

    public var zebrasThreshold: Double { get set }
