Instance Property

maximumExtendedDynamicRangeColorComponentValue

The current maximum color component value for the screen.

Declaration

var maximumExtendedDynamicRangeColorComponentValue: CGFloat { get }

Discussion

Typically the maximum value is 1.0, but if any rendering context on the screen has requested extended dynamic range, it may return a value greater than 1.0, depending on system capabilities and other conditions. Only rendering contexts that support extended dynamic range can use values greater than 1.0. When the value changes, didChangeScreenParametersNotification is posted.
