Scanning a barcode from an image

The Barcode Scanner efficiently analyzes a still image to identify and extract information from any barcodes present. Once detected, the scanner returns the barcode data in the result.

Processing the image

With the Scanbot SDK, you can detect barcodes from a still image, such as a JPG from the Photo Library or another source. The image should be provided as a file URI.

Single image barcode detection

Picking an image from the gallery using galleryManager:

var imageBitmapForDetection by remember { mutableStateOf<ImageBitmap?>(null) }

imageBitmapForDetection?.let { bitmap ->
    var barcodeResult = detectBarcodesFromImageBitmap(bitmap)
}

val galleryManager = rememberGalleryManager { sharedImage ->
    imageBitmapForDetection = sharedImage?.imageBitmap
}

LaunchedEffect(Unit) {
    galleryManager.launch()
}

To detect barcodes from a single image:

val imageBitmap: ImageBitmap = /* your ImageBitmap here */

// Specify the barcode formats you want to detect
val barcodeFormats = listOf(
    BarcodeFormat.AZTEC,
    BarcodeFormat.EAN_8,
    BarcodeFormat.UPC_A
    //...
)

// Specify accepted document formats for barcode detection
val documentFormats = listOf(
    BarcodeDocumentFormat.SEPA,
    BarcodeDocumentFormat.MEDICAL_CERTIFICATE
    //..
)

val result: List<BarcodeItem>? = detectBarcodesFromImageBitmap(
    imageBitmap = imageBitmap, 
    barcodeFormats = barcodeFormats, /* your list of BarcodeFormat here, or null */
    acceptedDocumentFormats = documentFormats /* your list of BarcodeDocumentFormat here, or null */
)

• Result: result - A list of recognized barcodes as items of List<BarcodeItem> type.
