19 | These four pixel formats are raw sRGB / Bayer formats with 8 bits per |
| 20 | sample. Each sample is stored in a byte. Each n-pixel row contains n/2 | |
| 21 | green samples and n/2 blue or red samples, with alternating red and | |
| 22 | blue rows. They are conventionally described as GRGR... BGBG..., | |
| 23 | RGRG... GBGB..., etc. Below is an example of one of these formats: | |
