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.
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>
