Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`float[]`	`getMatrix(long presentationTimeUs, boolean useHdr)`	Returns the 4x4 RGB transformation matrix to apply to the color values of each pixel in the frame with the given timestamp.
`default SingleFrameGlTextureProcessor`	`toGlTextureProcessor(Context context, boolean useHdr)`	Returns a `SingleFrameGlTextureProcessor` that applies the effect.

- Method Detail
  - getMatrix
```
float[] getMatrix(long presentationTimeUs,
                  boolean useHdr)
```
    Returns the 4x4 RGB transformation matrix to apply to the color values of each pixel in the frame with the given timestamp.
    
    Parameters:
    
    presentationTimeUs - The timestamp of the frame to apply the matrix on.
    
    useHdr - If true, colors will be in linear RGB BT.2020. If false, colors will be in linear RGB BT.709. Must be consistent with useHdr in toGlTextureProcessor(Context, boolean).
    
    Returns:
    
    The RgbMatrix to apply to the frame.
  - toGlTextureProcessor
```
default SingleFrameGlTextureProcessor toGlTextureProcessor(Context context,
                                                           boolean useHdr)
                                                    throws FrameProcessingException
```
    Description copied from interface: GlEffect
    
    Returns a SingleFrameGlTextureProcessor that applies the effect.
    
    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
