Reading Problems with CVB Barcode
tool did not read a simple 1D-Barcode (e. g. Code 39) in my
application. What could be the problem?
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
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).
