Operator Library: Base
The operator monitors the state of the input pixel stream and provides a register for reading out of the latest valid value via software.
Link Parameter | Input Link I |

Range | InputBitWidth |
The latest valid value from the input pixel stream is stored in the register Status which is readable via software. Note that the parameter is always of type unsigned. If you connected a signed link to the operator, reinterpret the value as signed value in your software. |
The use of operator GetStatus is shown in the following examples:
