Parameter Overview
– Row and Column
If the calibration process is successful, the WOI is modified to frame
the symbol and an additional margin area around the symbol, which the
WOI determines.
– Column
If the calibration process is successful, the WOI columns are modified
to frame the symbol vertically, plus an additional margin area around
the symbol, which the WOI Margin parameter determines.
– Row
If the calibration process is successful, the WOI rows are modified to
frame the symbol horizontally, plus an additional margin area around
the symbol, which the WOI Margin parameter determines.
– 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 WOI is modified according to the symbol
orientation. The scan line orientation is determined to be vertical if the
symbol tilt is between 225…315°, or between 45…135°. Otherwise, the
scan line is horizontal. If the symbol is vertical, the scan height
parameter sets the image column size, and is configured for full row
resolution. If the symbol is horizontal, the scan height parameter sets
the image row size, and is configured for full column resolution. The
scan line is centered in the middle of the symbol. If the symbol is tilted
such that the scan line does not pass completely through the symbol,
the scan width is adjusted to include the entire symbol. See
.
Figure 92 - Straight-line Scan
– Straight Line Framed
This parameter is the same as Straight Line, except that the WOI also
frames the scan line on the symbol length. The scan line includes the
symbol plus an additional margin area that the WOI Margin parameter
determines.
