===================
8-bit Bayer formats
===================

Description
===========

These four pixel formats are raw sRGB / Bayer formats with 8 bits per
sample. Each sample is stored in a byte. Each n-pixel row contains n/2
green samples and n/2 blue or red samples, with alternating red and
blue rows. They are conventionally described as GRGR... BGBG...,
RGRG... GBGB..., etc. Below is an example of a small V4L2_PIX_FMT_SBGGR8 image:

**Byte Order.**
Each cell is one byte.
