@john1jan

This library/module is only a wrapper around https://github.com/dm77/barcodescanner ─ so I think this issue doesn't belongs to here. Do you agree?

Maybe you can report it there.

I think there is some issue in ReactNative rendering. The same view works fine in Native Side. The camera preview is also very clear.

I used the same ZXingScannerView in a Native Activity and tested. It works great. But when the same view is used in React Native UI component it is blurring and not scanning barcodes.

Submitted a issue on this in react github repo, start commenting on it

Hi,

The component should be able to scan the following barcode formats:

BarcodeFormat.PARTIAL BarcodeFormat.EAN8 BarcodeFormat.UPCE BarcodeFormat.ISBN10 BarcodeFormat.UPCA BarcodeFormat.EAN13 BarcodeFormat.ISBN13 BarcodeFormat.I25 BarcodeFormat.DATABAR BarcodeFormat.DATABAR_EXP BarcodeFormat.CODABAR BarcodeFormat.CODE39 BarcodeFormat.PDF417 BarcodeFormat.QRCODE BarcodeFormat.CODE93 BarcodeFormat.CODE128

I never had an issue with blurring of the camera preview. Can you please provide a small project on github to reproduce the error? Also which react native version do you use?

It is working fine in full screen. The actual issue was, the BarcodeScannerView should be in full screen, I was displaying the BarcodeScannerView in half of the screen. So the Scanner view was getting distorted. But issue is still present in BarcodeScannerView when you reduce the height of the view.

I have made workaround, like this, Made the BarcodeScannerView fullscreen and placed my other view components on top of BarcodeScannerView.

Glad you found a workaround. I think I can close the issue then.
