Public methods
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 ARGB_8888 format.
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 ARGB_8888 format.
getLength
public int getLength(long presentationTimeUs)
Returns the length N of the 3D N x N x N LUT cube with the given timestamp.
getLutTextureId
public int getLutTextureId(long presentationTimeUs)
Must be called after toGlTextureProcessor.
release
public void release()
Releases the OpenGL texture of the LUT.
