Barcode Scanning: Truncated PDF417

[red5leader]

So from the old GitHub repo for android-vision there was an open issue googlesamples/android-vision#335 for being able to read PDF417 truncated barcode formats.

Is PDF417 truncated actually supported now with MLKit com.google.mlkit:barcode-scanning:16.0.3

It scans PDF417 just fine but I have been unsuccessful trying to read truncated PDF417 barcodes. If it is supported any guidance on what to send to my BarcodeScannerOptions would be most helpful.

Regular PDF417

Truncated PDF417

I also am having trouble scanning truncated / compacted PDF417 barcodes, albeit with the iOS MLKit SDK.

Thanks for the request!
It's not supported currently and will file internal feature request to track this.

Hey,

I see on the official MLKit website https://developers.google.com/ml-kit/vision/barcode-scanning/android

There is support for "Adds support for broken PDF417 start/stop pattern detection," Just wanted to confirm if this works for the truncated issue?

[zhouyiself]

Thanks for bumping this up!

Unfortunately not. Will ping here once there's update.

hello again, @zhouyiself just want to ask if this is supported in latest version?

[rjmangubat23]

Hello, for reference
I filed this in MLKit google issue tracker: https://issuetracker.google.com/issues/247450973?pli=1

Truncated PDF417 scanning with MLKit would be very much appreciated.

I'm afraid with the shift of priority in our team, there is no plan in the near future to address this.
