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