LutProperties
class LutProperties
| kotlin.Any | |
| ↳ | 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 android.view.SurfaceControl.Transaction#setLuts are by the HWC.
