	<title>Description</title>

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