NSButton和NSImageView中的图像模糊 [英] Images in NSButton and NSImageView Blurred

问题描述

我完全被困在这里；我正在修补一系列小图像并制作成按钮:

I am completely stumped here; I have a series of small images I'm tinkering with and making into buttons:

正如您所见，它们都非常脆且锋利，当我在预览"中打开png文件时保留了这些，而没有.

And as you can see they are all decently crisp and sharp, and retain this when I open the png files in Preview and what not.

但是，当我在Interface Builder的NSButtons和NSImageViews中使用它们时，将Scaling设置为None:

However, when I use them in NSButtons and NSImageViews in Interface Builder, setting Scaling to None:

图像变得非常模糊.我究竟做错了什么?我不知道从哪里开始，应该尝试什么.我应该回到图标上并尝试使其像素完美吗?它与抗锯齿或与此类似的事物有关吗?

The images become horribly blurred. What am I doing wrong? I don't know where to start and what to try; should I go back to the icons and try to make them pixel perfect? Does it have to do with anti-aliasing or something along those lines?

由于某种原因，即使我处于正常显示状态，似乎NSButtons和NSImageViews都在加载图像的高分辨率版本，这可以通过我添加到它们的浅蓝色笔划来识别.由于某些原因，Quartz Debug不会将这些图像识别为高分辨率图像，也没有红色.删除对@ 2x图像的引用确实可以解决问题...但是...

For some reason, it seems as if the NSButtons and NSImageViews are loading the high resolution versions of the images, even though I'm on a normal display, which can be identified by a slight light blue stroke I added to them. For some reason, Quartz Debug does not identify these as high resolution images and there's no red tint. Removing references to the @2x images does fix the problem... but...

推荐答案

如果您在NSImage的第一部分的WWDC 2012视频Advanced Tips and Tricks for High Resolution on OS X中检出了会话245，则会发现原因.

If you check out session 245 in the WWDC 2012 videos Advanced Tips and Tricks for High Resolution on OS X in the first section on NSImage you'll find out why.

NSImage没有高分辨率的概念-它仅使用最小像素大于其必须填充空间的图像-因此，如果NSImageView尺寸大于1x图像，它将请使用2x图像，因为它有更多像素.

NSImage doesn't have any concept of high resolution - it just uses the smallest image that has more pixels than the space it has to fill - so if your NSImageView is bigger in dimension than your 1x image it will use the 2x image as it has more pixels.
