This Python script provides a simple way to scan barcodes from images (local files or URLs) using the zxing-cpp library. It decodes barcodes, extracts their information, and visually highlights detected barcodes on the image. The script can be run directly to test barcode detection and display results with bounding boxes.

Thanks for sharing your work. I have a couple of issues with it that don't make this a good addition as is:

  • it depends on both PIL and opencv that seems redundant to me
  • it contains non-english language
  • it does not allow the user to pass in a url or filename
  • it constructs something like a copy of the Barcode object
  • it calls get_bytes twice, which does not make sense to me

There might be more. So I'll not merge this as is. If at all, it seems to make more sens to me to extend the existing demo_reader.py code.

i cleaned but,
It's just a arbitrary PR, don't worry too much about it. I saw something missing while working on the project with the kids and wanted to add it.
If you want, you can pull it, it's up to you :D
