有没有办法禁用Mac OS Retina Scaling为Swing应用程序？ [英] Is There A Way To Disable Mac OS Retina Scaling For A Swing App?

问题描述

我们有一个相当复杂的应用程序需要尽可能多的屏幕空间，自然视网膜显示Mac Books非常适合这个目的。

We have a rather complex application that needs as much screen real-estate as it can get, naturally the retina display Mac Books are excellent for this purpose.

然而，似乎在Swing中，这些设备使用的是点而不是像素。它们允许我将图标更改为更高分辨率的版本，如上所述此处。但由于我们做了很多复杂的图形和组件覆盖，我想只使用真实像素。要清楚，我不想修复模糊的图像或图标（在我的情况下不实用）只是为了禁用像素加倍。

However, it seems that in Swing those devices use points rather than pixels. They allow me to change the icons to higher resolution versions as discussed here. But since we do a lot of complex graphics and components overlays I want to just use "real pixels". To be clear I am not interested in fixing blurry images or icons (not practical in my case) just to disable the pixel doubling.

这个我找到的nofollow noreferrer>这个有趣（虽然很笨拙）的选项问题。

There is this interesting (albeit hacky) option I found thru this question.

推荐答案

据我所知，从JDK 1.8开始这是不可能的。唯一的解决方法是检测视网膜并在绘图时使用比例仿射变换。
然而，检测视网膜似乎是一个问题，因为似乎可用的唯一选项不在每个监视器的情况下，这可能不是一个好的解决方案：
如何检测Mac是否有来自Java的Retina显示器？

To my knowledge this is not possible as of JDK 1.8. The only workaround is to detect retina and use the scale affine transform when drawing. However, detecting retina seems to be a problem since the only option that seems to be available isn't on a per monitor case which is probably not a good solution: How can I detect whether a Mac has a Retina display from Java?
