Method Detail

• createGrayscaleFilter

  public static RgbFilter createGrayscaleFilter()

  Creates a new grayscale RgbFilter instance.

• createInvertedFilter

  public static RgbFilter createInvertedFilter()

  Creates a new inverted RgbFilter instance.

• getMatrix

  public float[] getMatrix​(long presentationTimeUs,
                           boolean useHdr)

  Description copied from interface: RgbMatrix
  Returns the 4x4 RGB transformation matrix to apply to the color values of each pixel in the frame with the given timestamp.

  Specified by:

  getMatrix in interface RgbMatrix

  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 RgbMatrix.toGlTextureProcessor(Context, boolean).

  Returns:

  The RgbMatrix to apply to the frame.

• toGlTextureProcessor

  public 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

  Specified by:

  toGlTextureProcessor in interface RgbMatrix

  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
