property System::Windows::Rect Viewport { System::Windows::Rect get(); void set(System::Windows::Rect value); };public System.Windows.Rect Viewport { get; set; }member this.Viewport : System.Windows.Rect with get, setPublic Property Viewport As RectProperty Value
The position and dimensions of the base tile for a TileBrush. The default value is a rectangle (Rect) with a TopLeft of (0,0) and a Width and Height of 1.
Remarks
When you paint an area by using a TileBrush, you use three components: content, tiles, and the output area. The following illustration shows how these three TileBrush components relate to each other.

The Viewport property determines the size and position of the tiles in a TileBrush. By default, a TileBrush has a single tile that fills the whole output area. The Stretch property controls how the TileBrush content fits into that tile. You can override this default behavior and specify the tile size by using the Viewport property.
Use the ViewportUnits property to specify whether the Viewport uses absolute or relative coordinates. If the coordinates are relative, they are relative to the size of the output area. The point (0,0) represents the upper-left corner of the output area, and (1,1) represents the lower-right corner of the output area. To specify that the Viewport property uses absolute coordinates, set the ViewportUnits property to Absolute.
The following illustration shows the difference in output when you set the ViewportUnits property of a TileBrush to either relative or absolute.
