13 | <para>This is a grey-scale image with a depth of 16 bits per | |
14 | pixel. The least significant byte is stored at lower memory addresses | |
15 | (little-endian). Note the actual sampling precision may be lower than | |
16 | 16 bits, for example 10 bits per pixel with values in range 0 to | |
17 | 1023.</para> | |
