LutProperties

Kotlin |Java

public final class LutProperties
extends Object

java.lang.Object
↳	android.hardware.LutProperties

Provides Lut properties of the device.

A Lut (Look-Up Table) is a pre-calculated table for color correction. Applications may be interested in the Lut properties exposed by this class to determine if the Lut(s) they select using SurfaceControl.Transaction.setLuts(SurfaceControl, DisplayLuts) are by the HWC.

Summary

Constants
`int`	`ONE_DIMENSION` The Lut is one dimensional
`int`	`SAMPLING_KEY_CIE_Y` use y of CIE XYZ as the gain value of a lut
`int`	`SAMPLING_KEY_MAX_RGB` use max of r,g,b channel as the gain value of a Lut
`int`	`SAMPLING_KEY_RGB` use r,g,b channel as the gain value of a Lut
`int`	`THREE_DIMENSION` The Lut is three dimensional

Public methods
`int`	`getDimension()`
`int[]`	`getSamplingKeys()`
`int`	`getSize()`

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
