Ciao! I’d like to scan some UPC barcodes to get the product number, and after some research I unsuccessfully used the following libraries Zxing for Processing (unable to load some plugins for gstreamer 1.0) and QRCode (throws some errors in the console and seems dedicated to 2d barcodes) Now I’m…

Hello Th3cG, You can find below my take on your problem. This is the process I did: Extract the middle row of the image Convert the color to 0 or 1 Get rid of the sides by finding the first black pixel in each direction Find the size of each band by dividing pixel total width (in pixels) by expe…

Woe… You can use ANY java library with processing. Sure, there is no library that works?

I suppose the point are not the libraries, but their usage… probably there is some piece missing and I’m not able to fix it. On Windows I’m having some troubles with gstreamer, here’s the screenshot while running Zxing for Processing, the BarcodeReaderCam example: [Immagine 2021-05-05 120424] @Ch…

When he doesn’t find the dll: Do you have the dll? You can (under windows) add the path to the path statement of windows iirc

Really no expert for QR… but have you installed GStream? What does the documentation tell you?

I neither have that dll nor found it reinstalling gstreamer; why does the software seek for a windows32 dll while I’m running a 64-bit OS?

Does it work even for 1D barcodes?

i have not trying it but i found out that if any project could achieve without any kind of libraries is more flexible

And, by the way, any suggestion on how to get the distance between two parallel lines?

@jafal thank you for your support. Before opening this topic I discarded that solution as seems to import too many libraries and it’s unclear if it’s oriented only to QR codes.
