hi Loic
The images that are attached to the topic are generated by our program and if I try to read bar codes, some are not read as I have indicated, and I can not understand why because the printing process and equal for all 9 the bar code. NB I read all the barcodes without using roi individual but the entire page.

Hello,

The lines of the non detected barcode are a little too thick for the engine sensitivity.
if you are in the situation in which you are sure to have n barcode to detect you can try to scale up the image, by resizing it to 200% for example, and start a new detection. This usually helps to obtain better results. This at least worked with the two images you've attached.

With best regards,

Loïc
