Problems reading long code39 codes

[vladf95]

Hi,

I'm using the quagga barcode reader in order to read the following barcode formats: code128, code39, ean8 and ean13

I'm having problems with code39, because it can't be read. My codes are long (length = 20), besides this, the codes start and end with "*" (so the length is 22).

What should I do in order to make it work?

This is the order of the readres in the Quagga_init:
readers : ["code_128_reader", "ean_reader", "ean_8_reader", "code_39_reader", "code_39_vin_reader"]

p.s. The reader works fine for the other three barcode formats.

Best regards,
Vlad

This problem still exists. @vladf95 Did you find a workaround, by any chance?

[mteneglio]

still having this problem, is there a workaround somekind, quagga is still not able to read barcode more than 15 chars ( with code_39_reader )
@bezo97 @vladf95 Did you find a workaround for this issue?

[bezo97]

@mteneglio nope, I went with another similar lib, called zxing-js

[vladf95]

@mteneglio I wasn't able to find a solution for the problem. I also used the zxing library.
