在某些地方，我启用了 sub antialiasing，而在其他地方，我没有。我使用结合 ClearType 的“显示”渲染模式。

但是，它确实是随机的，它使用灰度抗锯齿，而不是彩色抗锯齿。而且看起来很糟糕。我怎么能强迫它？

根据我猜的操作系统，它的工作方式不同。但奇怪的是，有些地方我有 SubAA，而另一些地方我没有。

当在不同的窗户上时，有些地方我整体上都有 subAA。您知道为什么会存在这种不一致吗？我要苏巴！！

谢谢

There are certain situations when ClearType will get disabled in the rendering path which means it will then revert to grey scale anti-aliasing:

  • When you use AllowsTransparency="True" on a Window

  • When ClearType is disabled in Windows Settings (and you haven't used TextOptions.TextRenderingMode="ClearType" to force the use of ClearType)

  • ClearType text does not display correctly on a background that is not fully opaque i.e you introduce some transparency.

  • If Text is rendered to an intermediate target due to the use of a:

    • VisualBrush
    • DrawingBrush
    • OpacityMask
    • Viewport2DVisual3D
    • Effect
    • BitmapEffect

Are you using TextOptions.TextFormattingMode="Display" on your top level element i.e. Window? (the property is inherited so you if you put it there it should apply to everything in your Window).

You can use RenderOptions.ClearTypeHint="Enabled" to re-enable ClearType in the rendering path but you may have artifacts because there was usually a good reason to disable it.

You can use TextOptions.TextHintingMode="Fixed" when you have animations and you don't want to have lower-quality text rendering (i.e. ClearType disabled) while the animation is in effect.

You can use TextOptions.TextRenderingMode="ClearType" to force ClearType to be used even then the Windows System Settings have not enabled it (this won't do anything special for you in this case, it's here for reference).
