Calibration Options
Straight Line
This feature is intended for use with linear symbologies. If the calibration process is successful,
the orientation of the symbol is determined and the Window of Interest is modified according
to the symbol orientation. The scan line orientation is determined to be vertical if the
symbol tilt is between 225° and 315°, or between 45° and 135°. Otherwise, the scan line
will be horizontal.
If the symbol is vertical, the image column size will be set by the scan height parameter,
and will be configured for full row resolution. If the symbol is horizontal, the image row size
will be set by the scan height parameter, and will be configured for full column resolution.
The scan line will be centered in the middle of the symbol. If the symbol is tilted such that
the scan line will not pass completely through the symbol, the scan width will be adjusted
to include the entire symbol. Refer to the diagram below:
Straight Line Framed
This parameter is the same as "Straight Line", except that the Window of Interest will also
frame the scan line on the symbol length as well. The scan line includes the symbol plus
an additional margin area determined by the WOI Margin parameter.
