Overview
When a trigger occurs, the toolbox sets the object's Logging property to 'on' and
starts storing the acquired frames in a buffer in memory, a disk file, or both. When the
acquisition stops, the toolbox sets the object's Logging property to 'off'.
The following figure illustrates when an object moves into a logging state and the
relation between running and logging states.
Logging State Transitions
Note After Logging is set to 'off', it is possible that the object might still be logging
data to disk. To determine when disk logging is complete, check the value of the
DiskLoggerFrameCount property. For more information, see “Logging Image Data to
Disk” on page 6-42.
The following figure illustrates a group of frames being acquired from the video stream
and being logged to memory and disk.
