Variants

GetStateNormalized

Gets the current backlight brightness as a percentage value between 0.0 and 1.0

Fields

responder: DeviceGetStateNormalizedResponder

SetStateNormalized

Sets the current backlight brightness as a percentage value between 0.0 and 1.0

Fields

state: State

responder: DeviceSetStateNormalizedResponder

GetStateAbsolute

Gets the current backlight brightness in nits

Fields

responder: DeviceGetStateAbsoluteResponder

SetStateAbsolute

Sets the current backlight brightness in nits. Not affected by the scale set by SetNormalizedBrightnessScale.

Fields

state: State

responder: DeviceSetStateAbsoluteResponder

GetMaxAbsoluteBrightness

Gets the maximum supported backlight brightness in nits, if known. Otherwise returns error ZX_ERR_NOT_SUPPORTED.

Fields

responder: DeviceGetMaxAbsoluteBrightnessResponder

SetNormalizedBrightnessScale

Scales the maximum normalized brightness by a percentage value in [0.0, 1.0], if supported. Otherwise returns error ZX_ERR_NOT_SUPPORTED. Values passed to SetStateNormalized will correspond to a maximum brightness of scale * GetMaxAbsoluteBrightness(). Calling this may change the current absolute brightness.

Fields

scale: f64

responder: DeviceSetNormalizedBrightnessScaleResponder

GetNormalizedBrightnessScale

Gets the current normalized brightness scale as a percentage value in [0.0, 1.0].

Fields

responder: DeviceGetNormalizedBrightnessScaleResponder
