Code 39 - Scanner unable to decode dashes embedded within the barcode #3

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
Hi Jordão,

I am using your dll to generate Code 39 barcode. The dll produces the barcode 
with no issues however, we have "dashes" embedded within the code that the 
scanner does not display when reading. 

I have attached a file for your reference. If you were to scan this file, it 
will not display the dashes. 

Can you please advice? Is there something we need to do so that the barcode 
scanner can read the barcode and display the ID number with dashes?

Thanks,
Ken

Hello Ken,

Can you please try to set the barcode settings as follows:

        NarrowWidth = 1.5f
        WideWidth = 3.5f

It seems I picked the wrong defaults for those values. Please tell me if that 
fixes the issue. If so, I'll later change the defaults to these values.

Regards,
Rodrigo Jordão

Hi Rodrigo,

Sorry to report to you that the scanner still cannot decode the barcode
with dashes after changing the settings. However the same id number used
for generating barcode through this free online tool works fine.

Any suggestions?

Thank you!
Ken

Hello Ken,

The only difference that I see from the generated barcode to the online 
generator you linked to is the height, which should not interfere in the 
reading. But anyway, you can try it:

    BarHeight = 100f
    NarrowWidth = 1.5f
    WideWidth = 3.5f

Apart from that, the only way I could reproduce your issue is to know which 
scanner you're using. If you could reproduce the issue with an online scanner, 
or a phone software scanner, it would be best.

Regards,
Rodrigo Jordao

Hello Jordão,

Is there a way to set the DPI resolution in nbarcodes? It is set to 72 but
we need to print at 300DPI...Can you please give some suggestions??

Hello, NBarCodes 2.0 is out. Please be aware that some changes were made to the 
API and to the default values used. Adjustments to your project might be 
needed. Please check if it fixes this issue.
