final actor PKStrokeRecognizerAn actor that recognizes handwritten strokes and searches for text in a drawing.
updateDrawing(drawing: PKDrawing): Promise<void>final func updateDrawing(_ drawing: PKDrawing) asyncUpdates the drawing the recognizer analyzes. Recognition expects handwriting and strokes scaled as if written on standard paper sizes in points, such as US-letter or A4. - Parameter drawing: The new drawing.
recognizedText(strokeIDs?: (Array<string>) | null): Promise<(string) | null>final func recognizedText(strokeIDs: Set<UUID>? = nil) async -> String?Returns the recognized text from the specified strokes in the drawing. - Parameter strokeIDs: The `id`s of the `PKStrokes` in `drawing` to analyze. Pass `nil` to return the recognized text from the whole drawing.
get unownedExecutor(): SDKHandlenonisolated final var unownedExecutor: UnownedSerialExecutor { get }Retrieve the executor for this actor as an optimized, unowned reference. This property must always evaluate to the same executor for a given actor instance, and holding on to the actor must keep the executor alive. This property will be implicitly accessed when work needs to be scheduled onto this actor. These accesses may be merged, eliminated, and rearranged with other work, and they may even be introduced when not strictly required. Visible side effects are therefore strongly discouraged within this property. - SeeAlso: ``SerialExecutor`` - SeeAlso: ``TaskExecutor``
get indexableContent(): Promise<(string) | null>final var indexableContent: String? { get async }A string suitable for indexing the drawing's recognized text in search systems such as Spotlight. The string may contain multiple concatenated candidate matches for recognized text in the drawing. - Important: This query runs low-priority background recognition. Interactive queries can cancel it, in which case it returns nil. Use the indexing query when the person isn't interacting with the device.
static init(preferredLanguages?: (Array<_Foundation_Locale_Language>) | null): PKStrokeRecognizerinit(preferredLanguages: [Locale.Language]? = nil)Creates a recognizer with the specified preferred languages. Languages are respected on a best-effort basis. Factors such as feature support may affect which languages the recognizer uses. - Parameters: - preferredLanguages: A list of languages to recognize ordered by descending priority. Pass nil to use the system languages. The system languages may be used if no listed language is available for recognition.
static get recognitionVersion(): numberstatic var recognitionVersion: Int { get }The version number of the recognition engine. If you persist results this recognizer returns, store this value alongside them and regenerate the results when running on an OS with a higher version number.
static get supportedLanguages(): Array<_Foundation_Locale_Language>static var supportedLanguages: Set<Locale.Language> { get }The languages the recognizer supports.
search(query: string, fullWordsOnly?: boolean, caseMatchingOnly?: boolean): Promise<Array<PKStrokeRecognizer_SearchResult>>final func search(_ query: String, fullWordsOnly: Bool = false, caseMatchingOnly: Bool = false) async -> [PKStrokeRecognizer.SearchResult]Searches the drawing for strokes whose recognized text matches the query. - Parameters: - query: The query string to search for. - fullWordsOnly: Restricts matches to whole words only. - caseMatchingOnly: Restricts matches to exact case. - Returns: An array of all results found.
