20 <para>These four pixel formats are packed raw sRGB /
21 Bayer formats with 10 bits per colour. Every four consecutive
22 colour components are packed into 5 bytes. Each of the first 4
23 bytes contain the 8 high order bits of the pixels, and the
24 fifth byte contains the two least significants bits of each
25 pixel, in the same order.</para>
26
27 <para>Each n-pixel row contains n/2 green samples and n/2 blue
28 or red samples, with alternating green-red and green-blue
29 rows. They are conventionally described as GRGR... BGBG...,
30 RGRG... GBGB..., etc. Below is an example of one of these
31 formats:</para>
