| <title>Description</title> |
| |
| <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> |
