It can be horizontal direction or vertical direction to be interrupted direction.
In this step, the interruption quantity n is the quantity of intermittent line, and the interruption quantity can (must be with value 1-10
Integer) between, such as 2,3,5, the printing interruption degree that different interruption quantity is formed is different.For example, interruption quantity is 3
When, represent 3 printing intermittent lines in the source bar code symbol be present.
In this step, the interruption ratio r is to be interrupted line width and the percentage of bar code module size, the percentage
Can between value 10-90%, such as 30%, 40%, 50%, 46%, 78%, 80%, 90%, 48.9%, 52.3%, it is different
The printing interruption degree that is formed of percentage it is different.For example, when percentage is 30%, it is 100 to represent bar code module size
During pixel, there is the printing intermittent line that 30 points are arranged to white.
Action five, according to the bar code module size unit, interruption ratio r, calculate interruption width wide=unit*r；
Action six, when the interruption direction be horizontal direction, it is interrupted quantity n according to described, the wide w of the bar code symbol,
The high h of bar code symbol, the source bar code symbol is from left to right subjected to n deciles in the horizontal direction, forms the horizontal decile of n bars
Line, each horizontal bisector both ends point coordinates are { (0, h/n*k), (w, h/n*k) }, k=1 ... .n；For described every
One horizontal bisector, a printing discontiguous area a is all generated, for the point (x, y) on the printing discontiguous area a, x values
