Calibration Options
Window of Interest (WOI) Framing
Definition: If a WOI framing mode is enabled, it will set the camera WOI to a full-size
image when calibration begins. Once a symbol is decoded, the camera
WOI will be re-sized both vertically and horizontally (regardless of which
WOI mode is enabled) to include the symbol plus an additional margin
area. This is done to accelerate the calibration process.
When a successful calibration process is completed, the camera WOI
will be adjusted according to the mode enabled. Otherwise, the original
WOI configuration will be retained.

Configured WOI
If WOI framing is not enabled, the current WOI configuration will be used until a symbol
has been decoded. After a symbol is decoded, the WOI is framed exactly as it would be if
a WOI framing mode was enabled. When the calibration process is complete, the original
WOI configuration is restored. Refer to the diagram below:
