| <title>Description</title> |
| |
| <para>The following four pixel formats are raw sRGB / Bayer formats with |
| 10 bits per colour. Each colour component is stored in a 16-bit word, with 6 |
| unused high bits filled with zeros. Each n-pixel row contains n/2 green samples |
| and n/2 blue or red samples, with alternating red and blue rows. Bytes are |
| stored in memory in little endian order. They are conventionally described |
| as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of one of these |
| formats</para> |
