如何将.PNG图像设置为我的WPF表单的TILED背景图像？

Question

我自己学习WPF,似乎无法找到一种方法来完成这项工作.

这是我的代码:

<Window x:Class="Test.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Test" Height="600" Width="800" >
<DockPanel>
    <Menu DockPanel.Dock="Right"
          Height="30"              
          VerticalAlignment="Top"
          Background="#2E404B"
          BorderThickness="2.6">
        <Menu.BitmapEffect>
            <DropShadowBitmapEffect Direction="270" ShadowDepth="3" Color="#2B3841"/>
        </Menu.BitmapEffect>                          
    </Menu>
</DockPanel>

如何显示平铺的背景图像？

Answer 1

将ViewportUnits设置为absolute,这将允许您在视口中定义图像的像素大小.在我的示例中,图像大小为32x32.

<Window.Background>
    <ImageBrush ImageSource="image.png" TileMode="Tile" ViewportUnits="Absolute" Viewport="0,0,32,32"/>
</Window.Background>

Answer 2

或者,也许你可以使用Visual Brush:

<Window
    x:Class="Test.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Test" Height="600" Width="800">
  <Window.Background>
    <VisualBrush TileMode="Tile" Viewport="0,0,0.5,0.5">
      <VisualBrush.Visual>
        <Image Source="image.png"></Image>
      </VisualBrush.Visual>
    </VisualBrush>
  </Window.Background>
</Window>
