    <title>Description</title>

    <para>This is a grey-scale image with a depth of 16 bits per
pixel. The least significant byte is stored at lower memory addresses
(little-endian). Note the actual sampling precision may be lower than
16 bits, for example 10 bits per pixel with values in range 0 to
1023.</para>
