我尝试将具有透明度的 PNG 图像应用到整个窗口中,但窗口始终是白色的。
有什么线索可以看到 PNG 的透明度吗?
谢谢!
C#
public SplashScreen()
{
InitializeComponent();
var myBrush = new ImageBrush();
var image = new Image
{
Source = new BitmapImage(
new Uri(
"pack://application:,,,/MyApp;component/Images/Logo.png"))
};
myBrush.ImageSource = image.Source;
Background = myBrush;
}
XAML
