Parámetros

strokeId
Tipo: System.Int32
Identificador del trazo.

strokePacketData
Tipo: array<System.Int32[]
Matriz que contiene los datos del paquete del trazo.

strokePacketDescription
Tipo: array<System.Guid[]
Matriz que contiene los identificadores de las propiedades del paquete.

Comentarios

strokePacketData contiene datos del paquete de todos los puntos del trazo. strokePacketDescription contiene los identificadores únicos globales (GUID) que describen los tipos de datos del paquete incluidos para cada punto del trazo. Para obtener una lista completa de las propiedades del paquete disponibles, vea la clase Microsoft.Ink.PacketProperty.

Este método no actualiza la DirtyRegion del analizador de entrada manuscrita.

Si el trazo especificado no está asociado al analizador de entrada manuscrita, este método termina sin actualizar dicho analizador.

Ejemplos

En el ejemplo siguiente se define un método, theInkAnalyzerBase_UpdateStrokesCacheBase, que controla el evento UpdateStrokesCacheBase de un objeto InkAnalyzerBase. Este método recupera los datos de trazo de un objeto Microsoft.Ink.Ink, theInk. En la práctica, si la aplicación utiliza un objeto Microsoft.Ink.Ink para almacenar los datos de trazo, debería utilizar la clase derivada Microsoft.Ink.InkAnalyzer.
