调整窗口大小时,保持两个图像相对缩放

假设有两个图像,一个用于背景,一个用于前景。前景正好位于背景的中间,覆盖了它的相对数量(例如50%),因此用户将它们视为单个图像。

问题在于我需要背景以各种尺寸填充Window。将其Stretch值设置为UniformToFill即可。但是如何保持前景仍然覆盖50%的背景?

使用矢量图像会更好,因为它可以在调整容器大小时缩放'本身'

然后根据窗口大小设置边距,如下所示:

<Window x:Class="MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    Height="400" Width="400">
<Grid>
    <Image Margin="100">
        <Image.Source>

要始终使用50%的窗口,您可以使用Converter绑定属性。

此外,也许this可以帮助您。
