需要較低分辨率的圖像「拉伸」至屏幕尺寸

我正在製作使用C＃WPF的視頻遊戲。我現在想要實現的是增加額外的分辨率。需要較低分辨率的圖像「拉伸」至屏幕尺寸

我的默認顯示器分辨率是1600x900。我使用相同尺寸的遊戲窗口和網格。

現在，我想添加更多的分辨率。我已經找到了一種簡單的方法來改變代碼中的值，問題在於另一個話題。

這就是遊戲在1600x900上的樣子。

然後，我試圖設置分辨率800x600。

我想實現的目標是使圖像的分辨率低於Windows中設置的分辨率，以獲得「延伸」並仍然覆蓋整個屏幕。

這就是我得到的。遊戲只佔用屏幕的一部分，其餘部分使用白色背景。

拉伸的窗口，我試圖實現的是這樣的。爲了創建這個圖像，我在圖形編輯器中拉伸了以前的圖像。我想讓遊戲自己做。

如果你看第一和第三屏幕的全尺寸，你會注意到它們是不同的，而較低的圖像有更糟糕的細節。

窗口或網格如何在Windows中具有較低的分辨率但仍覆蓋全屏？

UPDATE：用於遊戲畫面之一 - 主菜單

XAML中起步：

<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">

如何現在看起來：

如何它應該看起來如下：

只需卸下的HorizontalAlignment = 「左」 HEIGHT = 「600」 VerticalAlignment = 「評出的」 WIDTH = 「800」從你的網格，使網格可以拉伸至整個窗口，

如果你需要這些值使用窗口本身

編輯： 好了，我看到你設置的高度和寬度的每個元素（如按鈕），並且您將邊距設置爲將其移動到正確的位置，這不適用於不同的分辨率。可以說你把窗口寬度設置爲800，你的按鈕設置爲200。如果將窗口寬度更改爲1024，則此更改不會自動反映到按鈕，它將始終爲200（並且邊距也相同）

正確的解決方案是以正確的方式重寫xaml代碼，（你將使用Grid.ColumnsDefinition/RowDefinition，Stackpanels ..等），而不需要設置像素值。

但是，如果你在趕時間，你可以把視框的所有元素：

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

現在請注意，使用視框將根據視框的寬度和高度（舒展你的內容，因此它就像你做了什麼在圖形編輯器中）。另外請注意，應避免使用Viewbox，因爲它在資源方面非常昂貴

工作，我非常感謝！ – EvgenieT

你好，再次抱歉，但仍有一些問題。提供的解決方案適用於整個網格，我的意思是，網格只有一個圖像。但是每個網格上還有更小的圖像和按鈕，我需要給他們什麼屬性，所以他們不會移動？ – EvgenieT

完整xaml？它大約有2.5萬行，它不適合這裏。我可以用其他方式上傳嗎？ – EvgenieT

需要較低分辨率的圖像「拉伸」至屏幕尺寸
