Reading barcodes or QR codes from screen or image files

[pablo22]

Hi, I wonder if it's possible to decode a barcode or a QR code from the PC screen, or image file (such as PDF or TIFF).
We receive scans of forms with QR codes or traditional barcodes on it and need to decode those codes to use the data on them.
Thanks.

Hi pablo22,

There doesn't appear to be a barcode reading action in BP although I am not not sure about the recent versions.

If you are keen in reading the barcodes online then you can make use of such links.
https://www.onlinebarcodereader.com/
https://online-barcode-reader.inliteresearch.com/
But I do understand that there might be documents that cannot be uploaded to 3rd party websites and shouldn't be either.

So in that case something like the below can help

The same page has the link for the VB code too.

I believe searching for more such code can lead you to the right one.

There are also paid dlls available with code that make the barcode reading possible.
