  3. 48bpp (16bits per channel x 3 channels ) RGB Fixed Point.
  4. 48bpp (16bits per channel x 3 channels ) RGB Floating Point.
  5. 64bpp (16bits per channel x 4 channels ) RGBA Fixed Point.
  6. 64bpp (16bits per channel x 4 channels ) RGBA Floating Point.
  7. 32bpp (32bits per channel x 1 channel) Grayscale Fixed Point.
