InkRecognizer 類別

提供對 InkAnalyzer 所使用之手寫辨識器的存取。

命名空間： System.Windows.Ink
組件： IAWinFX (在 IAWinFX.dll 中)

備註

辨識器具有用來執行辨識的特定屬性 (Attribute) 和屬性 (Property)。辨識器的屬性 (Property) 必須在辨識發生之前決定。辨識器支援的屬性 (Property) 類型決定了它可以執行的辨識類型。例如，如果辨識器不支援草寫的手寫輸入，當使用者使用草寫時，它會傳回不正確的結果。

辨識器也有自動管理手寫輸入許多層面的內建功能。例如，它會判斷繪製筆劃之行的度量資訊。您可以傳回筆劃的行號，而因為辨識器內建功能的關係，您不需要指定判斷這些行度量的方式。

InkAnalyzer 會維護可用辨識器的 InkRecognizerCollection。若要存取這個集合，請使用 InkAnalyzer 的 GetInkRecognizersByPriority 方法。

範例

下列範例會定義傳回字串的方法。這個字串包含指定之 InkRecognizer 的相關資訊。這個範例中未示範 Helper 方法 ListCapabilities，這個 Helper 方法會使用反映傳回 InkRecognizer 的功能相關資訊。
