The Trigger class provides methods for activating the trigger mode. If the camera is in standby mode, it quits this mode and activates trigger mode.
In hardware trigger mode, image capture is delayed for each function call until the selected trigger event has occurred.
In software trigger mode, an image is captured immediately when Freeze() is called, or a continuous triggered capture is started when Capture() is called. In hardware trigger mode, you can use the Force() command to trigger an image capture even if no electric signal is present.
When you disable the trigger functionality, you can query the signal level at the trigger input. This option causes the camera to change to freerun mode.
