Focus Gestures

Defined in framework ScanditCaptureCore

FocusGesture

protocol FocusGesture : NSObjectProtocol

Added in version 6.6.0

Common protocol for all the focus gestures.

triggerFocus

open func triggerFocus(_ pointWithUnit: PointWithUnit) -> Void

Added in version 6.7.0

Triggers a focus as if the focus gesture was performed.

add

open func add(_ listener: any FocusGestureListener) -> Void

Added in version 6.7.0

Adds the listener to this gesture.

In case the same listener is already observing this instance, calling this method will not add the listener again. The listener is stored using a weak reference and must thus be retained by the caller for it to not go out of scope.

remove

open func remove(_ listener: any FocusGestureListener) -> Void

Added in version 6.7.0

Removes a previously added listener from this gesture.

In case the listener is not currently observing this instance, calling this method has no effect.

jsonString

open var jsonString: String { get }

Added in version 6.7.0

Returns the JSON representation of the focus gesture.

showUIIndicator

open var showUIIndicator: Bool { get, set }

Added in version 6.19.0

If enabled triggering the focus gesture will also show a visual indicator. Defaults to true.

TapToFocus

open class TapToFocus : NSObject, FocusGesture

Added in version 6.6.0

Tap to focus gesture.

init

init()

Added in version 6.6.0

Constructs a new TapToFocus instance. The focus strategy can be changed in the CameraSettings through focusGestureStrategy.
