Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`int`	`getLength(long presentationTimeUs)`	Returns the length N of the 3D N x N x N LUT cube with the given timestamp.
`int`	`getLutTextureId(long presentationTimeUs)`	Returns the OpenGL texture ID of the LUT to apply to the pixels of the frame with the given timestamp.

    Specified by:
    
    toGlTextureProcessor in interface GlEffect
    
    Parameters:
    
    context - A Context.
