Xaml 在图像上形成按钮

需要帮助，我是Xamarin的初学者

如何在图像上放置1和2个按钮？ 我的XAML：

试试这个： 您还需要为Im1和Im2设置边距

    <Grid>
          <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
          </Grid.RowDefinitions>

          <Image
              Grid.Row="0"
              Grid.RowSpan="3"
              Source="{Binding ImSource}"
              Aspect="AspectFill"
               />
      <ImageButton
          Grid.Row="0"
          Source="{Binding Im1}"
          HorizontalOptions="End" />

      <ImageButton
          Grid.Row="2"
           Source="{Binding Im2}"
          HorizontalOptions="Start"/>
    </Grid>
