a2391a80 | 20 | <para>These four pixel formats are raw sRGB / Bayer formats with |
039aa702 GL |
21 | 10 bits per colour. Each colour component is stored in a 16-bit word, with 6 |
22 | unused high bits filled with zeros. Each n-pixel row contains n/2 green samples | |
23 | and n/2 blue or red samples, with alternating red and blue rows. Bytes are | |
24 | stored in memory in little endian order. They are conventionally described | |
25 | as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of one of these | |
26 | formats</para> | |
