Barcode AR Responsive Annotation

Defined in framework ScanditBarcodeCapture

BarcodeArResponsiveAnnotation

open class BarcodeArResponsiveAnnotation : UIView, BarcodeArAnnotation

Added in version 7.5.0

Responsive annotations dynamically switch between two different info annotation variations based on the barcode’s size relative to the screen. This allows for different display styles when barcodes appear close-up versus far away in the camera view.

The annotation uses a configurable threshold to determine when to switch between the close-up and far-away variations. When the barcode area as a percentage of the screen area exceeds the threshold, the far-away annotation is displayed. Otherwise, the close-up annotation is shown.

Both the close-up and far-away annotations are BarcodeArInfoAnnotation instances, but either can be set to null to display nothing for that variation.

init

init(barcode: Barcode, closeUp closeUpAnnotation: BarcodeArInfoAnnotation?, farAway farAwayAnnotation: BarcodeArInfoAnnotation?)

Added in version 7.5.0

Constructs a new responsive annotation with the given barcode and annotation variations.

threshold

open class var threshold: CGFloat { get, set }

Added in version 7.5.0

The threshold (percentage of the barcode area vs screen area) that determines when to display close-up vs far-away annotations.

The value should be between 0.0 and 1.0, where 0.1 represents 10% of the screen area. The default value is 0.05.

Note

The threshold is a class-level property that applies to all instances of BarcodeArResponsiveAnnotation.

barcode

open var barcode: Barcode { get }

Added in version 7.5.0

The barcode instance for the annotation.

annotationTrigger

open var annotationTrigger: BarcodeArAnnotationTrigger { get, set }

Added in version 7.5.0

The trigger that causes the annotation to be presented. By default is BarcodeArAnnotationTrigger.highlightTapAndBarcodeScan.
