Zoom Gestures

Defined in framework ScanditCaptureCore

ZoomGesture

protocol ZoomGesture : NSObjectProtocol

Added in version 6.6.0

Common protocol for all the zoom gestures.

triggerZoomIn

open func triggerZoomIn() -> Void

Added in version 6.7.0

Triggers a zoom in as if the zoom in gesture was performed.

triggerZoomOut

open func triggerZoomOut() -> Void

Added in version 6.7.0

Triggers a zoom out as if the zoom out gesture was performed.

add

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

Added in version 6.1.0

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 ZoomGestureListener) -> Void

Added in version 6.1.0

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 zoom gesture.

SwipeToZoom

open class SwipeToZoom : NSObject, ZoomGesture

Added in version 6.6.0

Swipe to zoom gesture.

init

init()

Added in version 6.6.0

Constructs a new SwipeToZoom instance. The zoom levels can be changed in the CameraSettings through zoomFactor (zoom factor when zoomed out) and zoomGestureZoomFactor (zoom factor when zoomed in).

jsonString

open var jsonString: String { get }

Added in version 6.7.0

Implemented from ZoomGesture. See ZoomGesture.jsonString.
