Window of Interest (WOI) Framing
Definition: If WOI Framing is enabled, the camera's Window of Interest will be set to
a full size image when calibration begins. Once a symbol is decoded, the
camera WOI will be zoomed in both vertically and horizontally (regardless
of which WOI mode is enabled) to include the symbol plus an additional
margin. This is done to speed up the calibration process. When a successful
calibration is complete, the camera WOI will be adjusted according to the
mode enabled. Otherwise, the original WOI configuration will be retained.

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 calibration completes, the original WOI configuration
is restored.
Disabled
When this feature is disabled, the Window of Interest is not modified after the calibration
process is complete.
Row and Column
If the calibration process is successful, the Window of Interest will be modified to frame the
symbol as well as an additional margin area around the symbol, determined by the WOI
Margin parameter.
Row
If the calibration process is successful, the Window of Interest rows will be modified to
horizontally frame the symbol, plus an additional margin area around the symbol, determined
by the WOI Margin parameter.
Column
If the calibration process is successful, the Window of Interest columns will be modified to
vertically frame the symbol, plus an additional margin area around the symbol, determined
by the WOI Margin parameter.
