7.20. NarrowToWideRatio Property

Description

Returns or sets the ratio of the wide to narrow bar in a barcode.

Remarks

Some linear symbologies can have two module widths. The width of the wide one is a fixed multiple of the width of the narrow module (NarrowBarWidth). You can choose a value ranging from 2.0 to 3.0 for this ratio.

This property is valid only for Code 39, Code 25, Code 11, Codabar and Interleaved 2 of 5 symbologies. All others ignore this property. We also recommend you set a value between 2.5 to 3.0, so the barcode can be easier to be recognized.

Since the value may impact the readability of the barcode, we highly recommend that you test the barcode readability when you set the value to anything below 2.5.
