Not able to scan certain barcode

halaharr commented 10 months ago

What's happening?

App not able to scan certain barcodes when the barcode is white on transparent background. It used to work with react-native-vision-camera (V2.16.4) and vision-camera-code-scanner(V0.2.0). Please see the attached image where the barcode is white in transparent background.

Reproduceable Code

import { BarcodeFormat, scanBarcodes } from 'vision-camera-code-scanner'
import { runOnJS } from 'react-native-reanimated'
import { useCameraDevices, useFrameProcessor } from 'react-native-vision-camera'
import { Camera } from 'react-native-vision-camera'

  const frameProcessor = useFrameProcessor(frame => {
    'worklet'
    const detectedBarcodes = scanBarcodes(
      frame,
      [
        BarcodeFormat.CODE_128,
        BarcodeFormat.CODE_39,
        BarcodeFormat.CODE_93,
        BarcodeFormat.CODABAR,
        BarcodeFormat.EAN_13,
        BarcodeFormat.EAN_8,
        BarcodeFormat.ITF,
        BarcodeFormat.UPC_A,
        BarcodeFormat.UPC_E
      ],
      { checkInverted: true }
    )
    runOnJS(setBarcodes)(detectedBarcodes)
  }, [])

 <Camera
              style={StyleSheet.absoluteFill}
              device={device}
              isActive={keepScanning}
              frameProcessor={frameProcessor}
              frameProcessorFps={5}
              audio={false}
            />

Hey - this is related to the code scanner FP plugin you are using.
