| 17 | 16-bit depth data with distance values at each pixel |
| 18 | |
| 19 | |
| 20 | Description |
| 21 | =========== |
| 22 | |
| 23 | This is a 16-bit format, representing depth data. Each pixel is a |
| 24 | distance to the respective point in the image coordinates. Distance unit |
| 25 | can vary and has to be negotiated with the device separately. Each pixel |
| 26 | is stored in a 16-bit word in the little endian byte order. |
| 27 | |
| 28 | **Byte Order.** |
| 29 | Each cell is one byte. |
