当我向应用程序栏添加图标按钮时,如果正在使用黑暗主题,系统将负责显示白色图标,如果正在使用灯光主题,则显示黑色图标。我可以在我的应用程序的其他地方使用此自动着色我想从SDK目录中获取一个图标图像并在普通按钮上使用它,如果我可以让系统根据主题显示白色或黑色,那将是很好的。现在我正在使用转换器手动完成它,但如果有办法自动执行它会更干净。有谁知道一种方式?

<Button Background="{StaticResource PhoneContrastBackgroundBrush}" >
<Button.OpacityMask>
<ImageBrush ImageSource="/Images/icon.png"/>
</Button.OpacityMask>
</Button>
icon.png必须为白色

或使用SDK图片(appbar.basecircle.rest.png)围绕它们绘制一个圆圈
