Reading Problems with CVB Barcode

Question

The Question/fr/produits/serie/CVB.Barcode">CVB Barcode tool did not read a simple 1D-Barcode (e. g. Code 39) in my application. What could be the problem?

Résponse

If you are using the Barcode tool from CVB version 7.1.1 or older the reason could be the image: If the barcode is very long and not very high, then the older versions of Résponse/fr/produits/serie/CVB.Barcode">CVB Barcode cannot recognize the code.
This Problem has been fixed in CVB version 7.1.2.

Another possibility is that you do not adhere to the specifications of the Barcode Tool: Some codes require a so-​called 'quiet zone' around the code in which there are no symbols (or things that can be mistaken for symbols), and for all codes it is necessary to have a modulus size of at least two pixels (please have a look at Barcode documentation for details).
