Question

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

                </Setter.Value>
            </Setter>
        </Style>

用法：

<Button Style="{StaticResource FlatStyle}" BorderThickness="0" Width="48" Height="48">
                <Button.BorderBrush>
                    <ImageBrush ImageSource="/appbar.favs.rest.png"/>
                </Button.BorderBrush>
            </Button>

在WP7的其他地方自动图标着色的应用栏式？
