如何在WPF中做图片形状的按钮？

<Button Width="100" Height="100" Style="{StaticResource CustomButtonStyle}">
    <Image Source="path_to_your_image.png" Stretch="Fill"/>
</Button>

<Window.Resources>
    <Style x:Key="CustomButtonStyle" TargetType="Button">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Grid>
                        <Image Source="path_to_your_image.png" Stretch="Fill"/>
                        <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Window.Resources>
