13	<para>This is commonly the native format of digital cameras,
14reflecting the arrangement of sensors on the CCD device. Only one red,
15green or blue value is given for each pixel. Missing components must
16be interpolated from neighbouring pixels. From left to right the first
17row consists of a green and blue value, the second row of a red and
18green value. This scheme repeats to the right and down for every two
