20 These four pixel formats are packed raw sRGB / 27 These four pixel formats are packed raw sRGB / Bayer formats with 12
21 bits per colour. Every two consecutive samples 28 bits per colour. Every two consecutive samples are packed into three
22 bytes. Each of the first two bytes contain the 29 bytes. Each of the first two bytes contain the 8 high order bits of
23 the pixels, and the third byte contains the fo 30 the pixels, and the third byte contains the four least significants
24 bits of each pixel, in the same order. 31 bits of each pixel, in the same order.
