XAML窗口显示图像模糊

我是WPF中的新手，我试图在WPF窗口中显示图像，然后在absulute坐标中显示一个按钮和两个链接。我有两个问题：XAML窗口显示图像模糊

浮动控制是从一台计算机转移到其他
的图像模糊。我认为这正在调整。

表单必须是固定对话框，图像大小为800x560。

这里是我的代码：

WPF调整它正在运行的显示器的像素密度。考虑使用Grid Columns或其他布局控件，例如StackPanel而不是边距偏移。例如，你的按钮可以使用以下布局：

<StackPanel Orientation="Horizontal" Margin="10,0" HorizontalAlignment="Right"> 
    <Button x:Name="PreviousButton" Content="Previous" IsDefault="False" 
     Style="{DynamicResource ActionFlatButtonStyle}" Margin="4,0" 
     Width="90" Click="PreviousButton_Click"/> 
    <Button x:Name="NextButton" Content="Next" IsDefault="True" 
     Style="{DynamicResource ActionFlatButtonStyle}" Margin="4,0" 
     Width="90" Click="NextButton_Click"/> 
    <Button x:Name="CloseButton" Content="Close" IsDefault="False" 
     Style="{DynamicResource ActionFlatButtonStyle}" Margin="4,0" 
     Width="90" Click="CloseButton_Click"/> 
</StackPanel>

对于模糊图像，请尝试在Image定义使用UseLayoutRounding="False"。
