Cara: Mengatur Perataan Horizontal dan Vertikal Petak PetaBrush

  • Artikel

Contoh ini memperlihatkan cara mengontrol perataan konten horizontal dan vertikal dalam petak peta. Untuk mengontrol perataan horizontal dan vertikal dari , TileBrushgunakan properti dan AlignmentY .AlignmentX

Properti AlignmentX dan AlignmentY digunakan TileBrush ketika salah satu kondisi berikut ini benar:

Ratakan Petak PetaBrush ke sudut kiri atas

Contoh berikut menyelaraskan konten DrawingBrush, yang merupakan jenis TileBrush, ke sudut kiri atas petak petanya. Untuk meratakan konten, contoh mengatur AlignmentX properti ke DrawingBrushLeft dan AlignmentY properti ke Top. Contoh ini menghasilkan output berikut.

A TileBrush with top-left alignment
Petak PetaBrush dengan konten diratakan ke sudut kiri atas

//
// 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;

Ratakan GambarBrush ke sudut kiri atas

Contoh berikutnya menyelaraskan konten ke DrawingBrush sudut kiri atas petak petanya dengan mengatur AlignmentX properti ke Left dan AlignmentY properti ke Top. Ini juga mengatur Viewport dan TileMode dari DrawingBrush untuk menghasilkan pola petak peta. Contohnya menghasilkan output berikut.

A tiled TileBrush with top-left alignment
Pola petak peta dengan konten diratakan ke kiri atas dalam petak peta dasar

Ilustrasi menyoroti petak peta abase sehingga Anda dapat melihat bagaimana kontennya diratakan. Perhatikan bahwa AlignmentX pengaturan tidak berpengaruh karena konten DrawingBrush sepenuhnya mengisi ubin dasar secara horizontal.

tiledTopLeftAlignedTileBrush.AlignmentX = AlignmentX.Left;

// Set the brush's Viewport and TileMode to produce a
// tiled pattern.
tiledTopLeftAlignedTileBrush.Viewport = new Rect(0, 0, 0.25, 0.5);
tiledTopLeftAlignedTileBrush.TileMode = TileMode.Tile;

// Define the brush's content.
tiledTopLeftAlignedTileBrush.Drawing = ellipseDrawing;

// Use the brush to paint a rectangle.

Ratakan DrawingBrush ke sudut kanan bawah

Contoh akhir menyelaraskan konten petak DrawingBrush peta ke kanan bawah petak peta dasarnya dengan mengatur AlignmentX properti ke Right dan AlignmentY properti ke Bottom. Contohnya menghasilkan output berikut.

Sekali lagi, AlignmentX pengaturan tidak berpengaruh karena konten DrawingBrush sepenuhnya mengisi petak dasar secara horizontal.
