需要将较低分辨率的图像“拉伸”到屏幕尺寸

我正在使用C＃WPF制作视频游戏。我现在尝试实现的是添加其他解决方案。

我的默认显示器分辨率为1600x900。我正在为游戏的窗口和网格使用相同的大小。

现在，我想添加更多分辨率。我已经找到了一种简单的方法来更改代码中的值，问题出在另一个主题上。

这就是游戏在1600x900分辨率下的外观。

然后，我尝试将分辨率设置为800x600。

我要实现的是使图像的分辨率低于Windows中的分辨率，以“拉伸”并仍然覆盖整个屏幕。

That's what I get. The game only takes a part of the screen, and white background on the remaining part.

The stretched window, what I am trying to achieve looks like that. To create this image I stretched the previous image in graphics editor. I want the game do it by itself.

If you look at first and third screens at full size, you'll notice they are different, and that lower image has worse detail.

How can the window or grid has resolution lower that one in Windows, but still cover full screen?

UPDATE: Code for one of game screens - the main menu

                    <ControlTemplate>
                        <Image Source="Resources/Images/Interface/Blank.png" Stretch="Fill" Margin="12,0,6,0"/>
                    </ControlTemplate>
                </Button.Template>
            </Button>
        </Grid>
        <Label Content="0.7.1" HorizontalAlignment="Left" Height="46" Margin="1258,724,0,0" VerticalAlignment="Top" Width="53" FontSize="24" Foreground="#FFFBEEEE"/>
        <Button x:Name="btnResolution" Content="Button" HorizontalAlignment="Left" Height="104" Margin="1040,644,0,0" VerticalAlignment="Top" Width="181" Click="btnResolution_Click"/>
    </Grid>

Xaml at the start:

<Window
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" x:Name="wdwMain" x:Class="RealityIncognita.MainWindow"
    Height="900" Width="1600" ResizeMode="NoResize" WindowState="Maximized" Cursor="Cross" WindowStyle="None" Loaded="wdwMain_Loaded">
<Grid x:Name="areaContainer" HorizontalAlignment="Left" Height="900" VerticalAlignment="Top" Width="1600">

How it looks now:

Thank you, Evgenie

Just remove the HorizontalAlignment="Left" Height="600" VerticalAlignment="Top" Width="800" from your grid so that grid can stretch to the whole window,

if you need these values use it on the window itself

Edit: Okay, I see that you're setting the height and width for each element(like the buttons) inside the grid , and you're setting the margin to move them to the correct place, This will not work with different resolutions. lets say you set the window width to 800 and your button is set to be 200. if you change the window width to 1024, this change will not be reflected automatically to the buttons, it will always be 200 (and same goes for the margin)

The correct solution is to rewrite the xaml code in the correct way, (you will use Grids with Grid.ColumnsDefinition/RowDefinition, Stackpanels ..etc) without setting the values in pixels.

But if you're in hurry you can put all elements in a Viewbox:

<Window ....
    <Viewbox Stretch="Fill">
           <Grid x:Name="areaContainer" ....
           </Grid>
    </Viewbox>
</Window>

现在请注意，使用viewbox将根据Viewbox的宽度和高度来拉伸内容（就像在图形编辑器中一样）。另请注意，应避免使用Viewbox，因为它在资源方面非常昂贵
