- Method Detail
  - createFromCube
```
public static SingleColorLut createFromCube(int[][][] lutCube)
```
    Creates a new instance.
    lutCube needs to be a N x N x N cube and each element is an integer representing a color using the Bitmap.Config.ARGB_8888 format.
  - createFromBitmap
```
public static SingleColorLut createFromBitmap(Bitmap lut)
```
    Creates a new instance.
    LUT needs to be a Bitmap of a flattened HALD image of width N and height N^2. Each element must be an integer representing a color using the Bitmap.Config.ARGB_8888 format.
  - getLutTextureId
```
public int getLutTextureId(long presentationTimeUs)
```
    Must be called after toGlTextureProcessor(Context, boolean).
    
    Specified by:
    
    getLutTextureId in interface ColorLut
  - getLength
```
public int getLength(long presentationTimeUs)
```
    Description copied from interface: ColorLut
    
    Returns the length N of the 3D N x N x N LUT cube with the given timestamp.
    
    Specified by:
    
    getLength in interface ColorLut
  - release
```
public void release()
             throws GlUtil.GlException
```
    Description copied from interface: ColorLut
    
    Releases the OpenGL texture of the LUT.
    
    Specified by:
    
    release in interface ColorLut
    
    Throws:
    
    GlUtil.GlException
  - toGlTextureProcessor
```
public SingleFrameGlTextureProcessor toGlTextureProcessor(Context context,
                                                          boolean useHdr)
                                                   throws FrameProcessingException
```
    Description copied from interface: ColorLut
    
    This method must be executed on the same thread as other GL commands.
    
    Specified by:
    
    toGlTextureProcessor in interface ColorLut
    
    Specified by:
    
    toGlTextureProcessor in interface GlEffect
    
    Parameters:
    
    context - A Context.
    
    useHdr - Whether input textures come from an HDR source. If true, colors will be in linear RGB BT.2020. If false, colors will be in linear RGB BT.709.
    
    Throws:
    
    FrameProcessingException
