<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>
