LutProperties
public
final
class
LutProperties
extends Object
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.
