CSDK: Barcode bars width in pixels

Question:

What are the quality requirements for optimal barcode recognition?  

Answer:

For the BAR module both the width of the bars and the difference between the width of the narrow and the wide bars are important factors for good OCR results. The best results can be achieved if the narrow bars are at least 3 pixels thick and the wide bars are at least 4 pixels thicker than the narrow bars. The same requirements are true for the width of the space between the bars.
