How to set a .PNG image as a TILED background image for my WPF Form?

Question

I\'m learning WPF on my own and I can\'t seem to find a way to make this work.

Here\'s my code:

Answer 1

Or, perhaps, you could use 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>

Answer 2

Set the ViewportUnits to absolute, which will allow you to define the pixel size of your image in the Viewport. In my example the image size is 32x32.

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