- <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>
