爲什麼基於網格的可視化畫筆顯示水平和垂直網格線

如果您測試下面的代碼和任何明亮的圖像，您會看到在所用圖像上繪製了4列和4行。我需要這種配置來使用某種效果。基本上我做了它，它的工作原理，但我想刪除這些網格線，不知道如何。這可能與網格控件本身的實現有關嗎？網格的屬性ShowGridlines是false。爲什麼基於網格的可視化畫筆顯示水平和垂直網格線

有可能使用Canvas而不是網格並手動進行放置，但我想繼續使用Grid並使用Canvas作爲最後的解決方案。

您可以將RenderOptions.EdgeMode屬性設置爲Aliased在網格上，以避免這種影響：

<VisualBrush x:Name="DissolveInBrush" TileMode="None" > 
    <VisualBrush.Visual> 
     <Grid RenderOptions.EdgeMode="Aliased"> 
      ... 
     </Grid> 
    </VisualBrush.Visual> 
</VisualBrush>
