运行结果及报错内容

多幅图像拼接时,中间有白线

我的解答思路和尝试过的方法

<Grid Height="640" Width="1280">
    <Image x:Name="image11" HorizontalAlignment="Left" Width="640" Margin="0,0,0,0" Source="D:\shuju\image1\22_11.jpg" />
    <Image x:Name="image12" HorizontalAlignment="Left" Width="640" Margin="640,0,0,0" Source="D:\shuju\image1\22_12.jpg"/>
Grid>

像上面的方式拼接图像则没有白线,但是写代码会很麻烦

我想要达到的结果

我感觉Grid的拼接方式,应该能去掉白线,但是查了很多资料,没有结果,希望各路大师帮忙看下
