如何避免WPF中的单个像素行消失? [英] how to avoid a single pixel line disappear in wpf?

问题描述

我使用路径element(StrokeThickness="1" SnapsToDevicePixels="True") 在网格中.我想调整窗口大小，Grid元素由Viewbox元素包装.

I use a Path element(StrokeThickness="1" SnapsToDevicePixels="True") in Grid. I want to resize the window, the Grid element is wrapped by a Viewbox element.

问题

当我调整窗口大小时，路径将消失一段时间.如果将SnapsToDevicePixels设置为false，则Path元素可能会模糊，这不是我想要的.

When I resize the window, the Path will disappear some time. If I turn SnapsToDevicePixels to false, the Path element may blur which is not what I want.

XAML代码:

<Window x:Class="WpfApplication2.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="207" Width="475">
   <Viewbox Stretch="Fill">
       <Grid Height="320" Width="517">
          <Path Data="M0,0 H1 z" StrokeThickness="1" Stroke="Black" Margin="72,73,79,218" Stretch="Fill" SnapsToDevicePixels="True" MinHeight="1"/>
       </Grid>
   </Viewbox>

可惜，我没有声誉来发布运行时效果.

Pity for I have no reputation to post the runtime effect.

推荐答案

我已经对放置在Viewbox中的分隔符进行了相同的实验.其中一些消失了一些解决方案.要解决此问题，我将其替换为高度为1像素的边框:

I have experimented the same problem with separators put in a Viewbox. Some of these disappear for some resolutions. To fix it, I replace them with border with 1 pixel height :

< Border Background="DarkGray" Grid.Row="0" Grid.ColumnSpan="7" Height="1" />

这避免了一个像素的单行在viewBox中消失. 希望它对您也有用.

This avoid single line of one pixel to disappear in viewBox. Hope it could be useful for you too.
