Win7中的图标文件无效，字体缩放为125％

[英]Icon file invalid in Win7 only with fonts scaled to 125%

原文 2014-12-19 21:12:33 3 1 c#/ winforms/ visual-studio/ icons/ font-scaling

A customer has his fonts enlarged to 125% on Windows 7-64. 在Windows 7-64上，客户将其字体放大到125％。 This causes our app to crash with this error: 这会导致我们的应用程序因此错误而崩溃：

System.ArgumentException: Argument 'picture' must be a picture that can be used as a Icon. System.ArgumentException：参数'picture'必须是可用作Icon的图片。

To track down the problem, I loaded Visual Studio onto a VM running Win7-64 Pro, then opened my project. 为了追踪问题，我将Visual Studio加载到运行Win7-64 Pro的VM上，然后打开我的项目。 If the font is set to normal (100%), everything works fine, however if I change the Windows display font scaling to 125% and try to build the project, I get the same error message from the compiler! 如果字体设置为正常（100％），一切正常，但是如果我将Windows显示字体缩放到125％并尝试构建项目，我从编译器得到相同的错误消息！ That's right, the Visual Studio resource editor tells me the icon file is not valid, but when I put the font scaling back to 100%, everything is OK. 没错，Visual Studio资源编辑器告诉我图标文件无效，但是当我将字体缩放回100％时，一切正常。

As far as I can tell, it is a valid .ico file. 据我所知，这是一个有效的.ico文件。 In VS, I can double-click on it (from the Resources tab of project properties) and it opens in the icon editor. 在VS中，我可以双击它（从项目属性的“资源”选项卡），然后在图标编辑器中打开它。
The following sizes are implemented: 实施以下规模：

16x16,32 bit, BMP 16x16,32位，BMP
24x24,32 bit, BMP 24x24,32位，BMP
32x32,32 bit, BMP 32x32,32位，BMP
48x48,32 bit, BMP 48x48,32位，BMP
64x64,32 bit, BMP 64x64,32位，BMP
96x96,32 bit, BMP 96x96,32位，BMP
128x128,32 bit, BMP 128x128,32位，BMP
192x192,32 bit, BMP 192x192,32位，BMP
256x256,32 bit, BMP 256x256,32位，BMP
300x300,32 bit, BMP 300x300,32位，BMP

Any ideas? 有任何想法吗？

40x40 is also needed. 40x40也是需要的。

While reading this post: Which icon sizes should my Windows application's icon include? 阅读本文时：我的Windows应用程序的图标应包含哪些图标大小？

I noticed mention of 40x40 pixel image, which I'd never seen before, but 40 just happens to be 125% of 32, so I tried it. 我注意到提到了40x40像素的图像，这是我以前从未见过的，但40只恰好是32％的125％，所以我试了一下。

Although 40x40 isn't one of the normal sizes created by the icon-generator tools I've used, I was able to edit the icon file and manually add this size using the free trial of icofx (www.icofx.ro). 虽然40x40不是我使用的图标生成器工具创建的正常尺寸之一，但我能够编辑图标文件并使用icofx（www.icofx.ro）的免费试用版手动添加此尺寸。

Now our app runs on Win7 with 125% enlarged fonts. 现在我们的应用程序在Win7上运行，扩大了125％的字体。
