En este ejemplo se muestra cómo usar la propiedad TileMode de una TileBrush para crear un patrón.
TileMode propiedad permite especificar cómo se repite el contenido de un TileBrush, es decir, como mosaico para rellenar un área de salida. Para crear un patrón, establezca el TileMode en Tile, FlipX, FlipY, o FlipXY. También debe establecer el Viewport del TileBrush para que sea menor que el área que está pintando; de lo contrario, solo se produce un solo cuadro, independientemente de la configuración que use con TileMode.
Ejemplo
En el ejemplo siguiente se crean cinco DrawingBrush objetos, se les proporciona una configuración diferente TileMode y se usan para pintar cinco rectángulos. Aunque en este ejemplo se usa la DrawingBrush clase para demostrar TileMode el comportamiento, la TileMode propiedad funciona de forma idéntica para todos los TileBrush objetos, es decir, para ImageBrush, VisualBrushy DrawingBrush.
En la ilustración siguiente se muestra la salida que genera este ejemplo.
