Cómo: Establecer la alineación horizontal y vertical de TileBrush
En este ejemplo se muestra cómo controlar la alineación horizontal y vertical del contenido en un mosaico. Para controlar la alineación horizontal y vertical de un TileBrush use sus propiedades AlignmentX y AlignmentY.
Las propiedades AlignmentX y AlignmentY de un TileBrush se usan cuando se cumple alguna de las condiciones siguientes:
La propiedad Stretch es Uniform o UniformToFill y el Viewbox y Viewport tienen diferentes relaciones de aspecto.
La propiedad Stretch es None y el Viewbox y Viewport son tamaños diferentes.
Alinear TileBrush a la esquina superior izquierda
En el ejemplo siguiente se alinea el contenido de un DrawingBrush, que es un tipo de TileBrush, a la esquina superior izquierda del mosaico. Para alinear el contenido, el ejemplo establece la propiedad AlignmentX del DrawingBrush en Left y la propiedad AlignmentY en Top. Este ejemplo produce el siguiente resultado:
TileBrush con alineación de contenido en la esquina superior izquierda
//
// Create a TileBrush and align its
// content to the top-left of its tile.
//
DrawingBrush topLeftAlignedTileBrush = new DrawingBrush();
topLeftAlignedTileBrush.AlignmentX = AlignmentX.Left;
topLeftAlignedTileBrush.AlignmentY = AlignmentY.Top;
// Set Stretch to None so that the brush's
// content doesn't automatically expand to
// fill the entire tile.
topLeftAlignedTileBrush.Stretch = Stretch.None;
// Define the brush's content.
GeometryGroup ellipses = new GeometryGroup();
ellipses.Children.Add(new EllipseGeometry(new Point(50, 50), 20, 45));
ellipses.Children.Add(new EllipseGeometry(new Point(50, 50), 45, 20));
Pen drawingPen = new Pen(Brushes.Gray, 10);
GeometryDrawing ellipseDrawing = new GeometryDrawing(Brushes.Blue, drawingPen, ellipses);
topLeftAlignedTileBrush.Drawing = ellipseDrawing;
// Use the brush to paint a rectangle.
Rectangle rectangle1 = new Rectangle();
rectangle1.Width = 150;
rectangle1.Height = 150;
rectangle1.Stroke = Brushes.Red;
rectangle1.StrokeThickness = 2;
rectangle1.Margin = new Thickness(20);
rectangle1.Fill = topLeftAlignedTileBrush;

Alinear DrawingBrush a la esquina inferior derecha
En el ejemplo siguiente se alinea el contenido de un DrawingBrush a la esquina inferior derecha de su mosaico estableciendo la propiedad AlignmentX en Right y la propiedad AlignmentY en Bottom. El ejemplo genera el siguiente resultado.

Alinear DrawingBrush a la esquina superior izquierda
En el ejemplo siguiente se alinea el contenido de un DrawingBrush a la esquina superior izquierda de su mosaico estableciendo la propiedad AlignmentX en Left y la propiedad AlignmentY en Top. También establece el Viewport y TileMode del DrawingBrush para generar un patrón de mosaico. El ejemplo genera el siguiente resultado.
Patrón de mosaico con el contenido alineado en la parte superior izquierda en el mosaico base
La ilustración destaca el mosaico base, por lo que puede ver cómo se alinea el contenido. Observe que la opción AlignmentX no tiene efecto porque el contenido del DrawingBrush rellena completamente el mosaico base en sentido horizontal.
//
// Create a TileBrush that generates a
// tiled pattern and align its
// content to the top-left of its tile.
//
DrawingBrush tiledTopLeftAlignedTileBrush = new DrawingBrush();
tiledTopLeftAlignedTileBrush.AlignmentX = AlignmentX.Left;
tiledTopLeftAlignedTileBrush.AlignmentY = AlignmentY.Top;
tiledTopLeftAlignedTileBrush.Stretch = Stretch.Uniform;
// Set the brush's Viewport and TileMode to produce a
// tiled pattern.

tiledTopLeftAlignedTileBrush.TileMode = TileMode.Tile;
// Define the brush's content.

En los ejemplos se usan objetos DrawingBrush para mostrar cómo se usan las propiedades AlignmentX y AlignmentY. Estas propiedades se comportan de forma idéntica para todos los pinceles de mosaico: DrawingBrush, ImageBrush y VisualBrush.
