| |
| <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> |
