Question

我在拉伸图像以填充按钮方面遇到问题，我是UWP的新手，这是我的代码：

 <Grid  Margin="0,0,0,54" VerticalAlignment="Bottom" Height="39" Style="{Binding HorizontalAlignment, ElementName=grid}" ScrollViewer.HorizontalScrollBarVisibility="Auto">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*" />
            <ColumnDefinition Width="*" />
        </Grid.ColumnDefinitions>

        <Button Grid.Column="0"  Height="39" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >
            <Image Source="images/icon1.png" Stretch="Fill" RenderTransformOrigin="0.5,0.5" UseLayoutRounding="True" d:LayoutRounding="Auto" />

        </Button>
        <Button Grid.Column="1"  Height="39" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >
            <Image Source="images/icon2.png" Stretch="Fill" RenderTransformOrigin="0.5,0.5" UseLayoutRounding="True" d:LayoutRounding="Auto" />
        </Button>
