Changing the Threshold Values for Right and Left Margins
When a bar code is printed inside of quadrangle, scanning may not be possible because there is
not enough left and/or right marginal space. By making change on the right and left marginal
threshold values, scanning a bar code becomes possible. See the table below.
Table 2.52
When the left marginal
space is narrow.
When the right marginal space is
narrow.
When both right and left
marginal spaces are narrow.
The functions of the Laser Scanner Library relevant to the “Changing the threshold values for
Right and Left margins” are as follows.
OBRSetMarginCheckRatio
:
Sets up a threshold value for right and left side space margins.
OBRGetMarginCheckRatio
:
Retrieves the threshold value for right and left side space margins.
Changing the Thickness of Bars
If bars that form a bar code are printed thick because blurring or scratchy white bars (spaces
between two bars) are printed thinly, the bar ratio will not be correct causing scanning incorrectly.
Adjusting the thickness of these bars makes scanning the bar code possible. This method is
applicable if all bars of a bar code are either too thick or too thin because the method is applied to
the whole of a bar code.
The functions of the Laser Scanner Library relevant to the “Changing the thickness of bars” are as
follows.
OBRSetBarWidthAdjustment
:
Sets up the adjustment of thickness of bars.
OBRGetBarWidthAdjustment
:
Retrieves the adjustment set for the thickness of bars.
