c# - FlowDocument 中的段落边框显得模糊，SnapsToDevicePixels 和 UseLayoutRounding 都不起作用

Question

当我使用Property 在in内的元素BorderThickness上绘制边框时，有时边框看起来很模糊。ParagraphFlowDocumentFlowDocumentScrollViewer

这是我的代码片段。

<Grid>
    <FlowDocumentScrollViewer>
        <FlowDocument>
            <Paragraph BorderBrush="Black" BorderThickness="0.5">This is a paragraph</Paragraph>
            <Paragraph BorderBrush="Black" BorderThickness="0.5">This is a paragraph</Paragraph>
            <Paragraph BorderBrush="Black" BorderThickness="0.5">This is a paragraph</Paragraph>
        </FlowDocument>
    </FlowDocumentScrollViewer>
</Grid>

我试图将SnapsToDevicePixels="True"andUseLayoutRounding="True"放在Gridor上FlowDocumentScrollViewer（因为它Paragraph本身不支持这些属性），但没有任何反应。

这个问题还有问题吗？如果没有，我该如何解决？

<Grid RenderOptions.EdgeMode="Aliased">
        <FlowDocumentScrollViewer>
            <FlowDocument>
                <Paragraph Margin="2" BorderBrush="Black" BorderThickness=".5">This is a paragraph</Paragraph>
                <Paragraph Margin="2" BorderBrush="Black" BorderThickness=".5">This is a paragraph</Paragraph>
                <Paragraph Margin="2" BorderBrush="Black" BorderThickness=".5">This is a paragraph</Paragraph>
            </FlowDocument>
        </FlowDocumentScrollViewer>
    </Grid>
