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 zoomed-in 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.
Serial Cmd:
<K529,gain,shutter speed,focus position,symbol type,WOI framing,WOI margin,line scan height,processing>
Default:
Disabled
Options:
0 = Disabled
1 = Row and Column
 
2 = Row
3 = Column
 
4 = Straight Line
5 = Straight Line Framed

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:
