Description | Called when a new camera frame is available. Use the read() method to capture this frame. If there is more than one capture device in the program, captureEvent() is called each time any of the devices has a new frame available. Use an if() to determine which device is triggering the event. See the above example for implementation details.
Syntax |
    void captureEvent(Capture which) {
      statements
    }
