如何改变透明图像的颜色？

Question

我有一些黑白的透明图像。我想用颜色选择器改变这些透明图像的颜色。我怎么能这样做。

  <Image  x:Name="img" HorizontalAlignment="Left" Stretch="Fill"  Width="50" Height="50"  Margin="148,263,0,375"   >
        </Image>
      <c4fToolkit:ColorPicker x:Name="picker" Height="200" 
             Width="200" ColorChanged="picker_ColorChanged"  Margin="270,283,10,245" Opacity="0.5" />

.cs代码是

private void picker_ColorChanged(object sender, System.Windows.Media.Color color)
{
    tattoo.Source = new SolidColorBrush(color);
}

您可以将图像封装在堆叠面板或网格中并设置其背景

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="100"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
    <StackPanel Background="Aqua" Height="100" Width="100" Grid.Row="0">
    <Image Name="img" Source="Assets/StoreLogo.scale-240.png" Height="100" Width="100"/>
    </StackPanel>
</Grid>
